Brandon invested $9,200 in an account paying an interest rate of 3 1/4%
compunded quarterly. Lamonte invested $9,200 in an account paying an interest rate of 2 7/8% compounded monthly. After 19 years, how much more money would Brandon have in his account than Lamonte, to the nearest dollar?

Answers

Answer 1

Answer:

$1141

Step-by-step explanation:

The general formula for compound interest is:

[tex]A(t)=P(1+r/n)^n^t[/tex], where A is the amount in dollars, P is the principal (i.e., amount invested), r is the interest rate, n is the number of compounding periods, and t is the time in years.

For Brandon's account (and equation), P = $9200, r = 0.0325, n = 4 and t = 19.

Explanations for r and n:

We always convert the percentage to a decimal when dealing with interest.  3 1/4% is the same as 3.25%.  We find the decimal by moving the decimal point two places to the right or by dividing 3.25 by 100 which gives us r = 0.0325Quarterly divides a unit into 4.  There are 12 months in a year and dividing 12 into 4 means that the money is compounded every 3 months

Now, we can simply plug in everything to find the amount Brandon would have in 19 years and round to the nearest dollar (i.e., nearest whole number):

[tex]A_{Brandon}(19)=9200(1+0.0325/4)^(^4^*^1^9^)\\ A_{Brandon}(19)=9200(1.008125)^7^6\\ A_{Brandon(19)}=17016.92431=17017[/tex]

For Lamonte's account (and equation), P = $9200, r = 0.02875, n = 12, and t = 19

Explanations for r and n:

2 7/8% is the same as 2.875% and when we move the decimal two places to the left (or divide 2.875 by 100), our decimal for r is 0.02875There are 12 months in year so monthly means that the money is compounded every month.  This is why n = 12 when money is compounded monthly

We can again plug in the values into the general equation to find the amount Lamonte would have in 19 years and round to the nearest dollar/whole number:

[tex]A_{Lamonte}(19)=9200(1+0.02875/12)^(^1^2^*^1^9^)\\ A_{Lamonte}(19)=9200(1.002395833)^2^2^8\\A_{Lamonte}(19)=15875.86592=15876[/tex]

Now we can subtract Lamonte's amount (15875) from Brandon's (17017) to find how much more Brandon would have in his account than Lamonte in 19 years:

17017 - 15876 = $1141

**If you didn't do any intermediate rounding and waited until the very last subtraction to round, you'd still get a similar answer

17016.92431 - 15875.86713 = 1141.05718 = $1141

What is coordinate?

In mathematics, a coordinate refers to a set of numbers that identifies the position or location of a point in a space. Coordinates can be used to specify the position of objects in one, two, or three-dimensional spaces. The most common types of coordinates used in mathematics are the Cartesian coordinates, which consist of an ordered pair of numbers representing the x and y coordinates of a point in a two-dimensional space, and the three-dimensional Cartesian coordinates, which consist of an ordered triple of numbers representing the x, y, and z coordinates of a point in a three-dimensional space. Coordinates are widely used in geometry, algebra, and other branches of mathematics.

Here,

To apply the transformation Is,-1 ° r y-axis, we need to reflect each point of the original figure across the y-axis. This is done by changing the sign of the x-coordinate and leaving the y-coordinate unchanged. The coordinates of the vertices of AJRB are J(1,-2), R(-3,6), and B(4,5). Applying the transformation, we get:

J'(-1,-2) (x-coordinate changes sign, y-coordinate stays the same)

R'(3,6) (x-coordinate changes sign, y-coordinate stays the same)

B'(-4,5) (x-coordinate changes sign, y-coordinate stays the same)

Answers

The solution of the given problem of unitary method comes out to be beam's maximum bending moment is 180 Nm.

=> wL = 40 N/m x 2 m = 80 N, where RA =

=> RBv - RA = 0 (sum of forces in the vertical direction)

=> RBh = 0 (sum of forces in the horizontal direction) (sum of forces in the horizontal direction)

To solve for RBv, we obtain:

=> 80 N = RBv = RA

Hence, the responses at support points A and B are as follows:

=> RA = 80 N (vertical response at A) (vertical reaction at A)

=> RBv = 80 N (vertical response at B) (vertical reaction at B)

=> RBh = 0 N (horizontal reaction at B) (horizontal reaction at B)

=> M = 80 N x 2 m - 40 N/m x (2 m)2/2 - 500 Nm

=> -180 Nm, where MB = RA x L - wL2/2 -

Keep in mind that the bending moment is opposite the applied moment, as shown by the negative sign.

Thus, at point B, the beam's maximum bending moment is 180 Nm.

Answer:

4.  4/13

5.  7/13

6.  4/13

Step-by-step explanation:

A standard deck has 52 cards, 4 suits, each suit has cards Ace through 10 and the face cards, Jack, Queen, King.

If the idea of suits confuses you, think about Uno where the cards are blue, yellow, green, and red. Only here the suits are Diamonds, Clubs, Hearts, and Spades

To calculate compound probability use the following formula:

P(A ∪ B) = P(A) + P(B) - P(A | B)

This says that the probability of A or B occuring is the probability of A, plus the probability of B, minus the probability of them both occuring at the same time.

4)  Randomly selecting a diamond or a seven.

There are 13 diamonds in a deck and 4 sevens, one from each suit. The joint event for this probabaility is randomly drawing a 7 of diamonds. There is only one of these in the deck.

P(Diamond ∪ 7) = P( Diamond ) + P( 7 ) - P( Diamond | 7)

                         = 13/52 + 4/52 - 1/52

                         = 16/52 = 4/13

5)  Randomly selecting a red card or a queen.

There are 26 red cards in the deck, from diamonds and hearts suits, 13 from each. There are 4 queens in the deck, one from each suit. The joint event is a queen of a diamonds or hearts, which there are 2 of in the deck.

P( Red ∪ Queen ) = P( Red ) + P( Queen ) - P( Red | Queen)

                             = 26/52 + 4/52 - 2/52

                             = 28/52 = 7/13

6) Randomly selecting a three or a face card.

There are 4 threes in a deck of cards, one from each suit. There are 12 face cards in a deck (Jack, Queen, and King with three from each suit). There is no joint event because you cannot draw a three and a face card. So this time we subtract 0 because the events are mutually exclusive.

P( 3 | Face ) = P( 3 ) + P( Face ) - P( 3 | Face )

                   = 4/52 + 12/52 - 0/52

                   = 16/52 = 4/13

Answers

We can factor the left side of the equation and use the zero product property to find possible values of a. We get a=-3 and a=2. By substituting these values back into the original equation, we can find the corresponding values of b which are -18 and 12, respectively.

What is algebra?

Algebra is a branch of mathematics that deals with symbols and the rules for manipulating those symbols to solve equations and understand relationships between variables. It involves using letters and symbols to represent numbers and quantities, and manipulating equations to solve for unknown variables. Algebra is used in various fields of study, including science, engineering, economics, and finance.

According to the given information:

To solve for the possible values of a and b given the equation:

We can use algebraic manipulation to rewrite the equation in terms of one variable.

Starting with:

we can simplify the left side of the equation by factoring out a common factor of (a + 3):

Now, we can use the zero product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.

Therefore, we have two possibilities:

(a + 3) = 0

If a + 3 = 0, then a = -3. Substituting this value of a back into the original equation, we get:

(2a - 3) = 0

If 2a - 3 = 0, then a = 3/2. Substituting this value of a back into the original equation, we get:

Now we have found the possible values of a. To find the corresponding values of b, we can substitute each value of a into either of the original equations and solve for b. Let's use the first equation:

When a = -3, we have:

Simplifying, we get:

-3b = -54

Dividing both sides by -3, we get:

b = 18

Therefore, when a = -3, b = 18.

When a = 2, we have:

Simplifying, we get:

2b = 12

Dividing both sides by 2, we get:

b = 6

Therefore, when a = 2, b = 6.

Thus, the possible values of a are -3 and 2, and the corresponding values of b are -18 and 12, respectively.

Therefore,We can factor the left side of the equation and use the zero product property to find possible values of a. We get a=-3 and a=2. By substituting these values back into the original equation, we can find the corresponding values of b which are -18 and 12, respectively

In conclusion  the solution to the system of equations is x = 1 and y = 2.

How to justify each step?

Here are the steps to solve the system of equations:

5x - y = 3

x + 2y = 5

To eliminate y, we can multiply the second equation by 2:

2(x + 2y = 5)

2x + 4y = 10

Now we can add the first equation and the new second equation together, to eliminate y:

5x - y = 3

2x + 4y = 10

7x = 13

To solve for x, we can divide both sides by 7:

7x / 7 = 13 / 7

Simplifying, we get:

x = 1

Now we can use substitution to find y. We can substitute x = 1 into the first equation:

5x - y = 3

5(1) - y = 3

Solving for y, we get:

-y = -2

To solve for y, we can divide both sides by -1:

-y / -1 = -2 / -1

Simplifying, we get:

y = 2

So, the solution to the system of equations is x = 1 and y = 2.

The steps in solving the system of equations are justified using various properties of equality, as follows:

Step 1 uses the multiplication property of equality, which states that multiplying both sides of an equation by the same nonzero number does not change the solution set of the equation.

Step 2 uses the addition property of equality, which states that adding the same quantity to both sides of an equation does not change the solution set of the equation.

Step 3 uses the division property of equality, which states that dividing both sides of an equation by the same nonzero number does not change the solution set of the equation.

Step 4 uses the substitution property of equality, which states that if two expressions are equal, then one can be substituted for the other in any equation or expression without changing the solution set.

Step 5 uses the subtraction property of equality, which states that subtracting the same quantity from both sides of an equation does not change the solution set of the equation.

Step 6 uses the substitution property of equality again.

Step 7 uses the division property of equality again.

Suppose stop lights at an intersection alternately show green for one minute, and red for two minutes (no yellow). Suppose a car arrives at the lights at a time distributed uniformly from 0 to 3 minutes. Let X be the delay of the car at the lights (assuming there is only one car on the road). E(X) is: a. none of the choices given b. 3/8
c. 1/4
d. 2/3

Answers

The expected value of the car representing the delay of the car at one of the light as per distribution of time is given by option d. 2/3.

For the probability density function of X.

Divide the interval from 0 to 3 minutes into three sub-intervals,

The first minute, during which the car will pass the intersection if the light is green.

The second minute, during which the car will be delayed by one minute if the light is red.

The third minute, during which the car will be delayed by two minutes if the light is red.

The probability of the car arriving during the first sub-interval is 1/3.

If the light is green, the car will pass immediately with no delay.

If the light is red, the car will be delayed by one minute.

So the probability density function of the delay during this sub-interval is,

f(x) ={  1/3, if 0 ≤ x ≤ 1

         0,     otherwise  }

Probability of the car arriving during the second sub-interval is also 1/3.

If the light is red, the car will be delayed by one minute.

If the light is green, the car will be delayed by two minutes.

So the probability density function of the delay during this sub-interval is,

f(x) = { 1/6,      if 1 ≤ x ≤ 2

         1/3,       if 2 ≤ x ≤ 3

         0,          otherwise }

Probability of the car arriving during the third sub-interval is also 1/3.

If the light is red, the car will be delayed by two minutes.

If the light is green, the car will be delayed by three minutes.

But since the car cannot wait for more than three minutes, the delay during this sub-interval is bounded by 2 minutes.

So the probability density function of the delay during this sub-interval is,

f(x) = {  1/6,     if 2 ≤ x ≤ 3

             0,      otherwise  }

Now,

calculate the expected value of X by integrating the product of the delay and the probability density function over the entire range of possible delays

E(X) = [tex]\int_{0}^{3}[/tex] x f(x) dx

= [tex]\int_{0}^{1}[/tex]0 dx + [tex]\int_{1}^{2}[/tex] x (1/6) dx + [tex]\int_{2}^{3}[/tex] x(1/6) dx

= (1/6)(1/2)  [(2^2 - 1^2) + (3^2 - 2^2)]

= (1/12) [ 3 + 5 ]

= 8/12

= 2/3

Therefore, the expected value of the delay of the car at the light is equal to option d. 2/3.

BC=?

Answers

Answer:

BC = 62

Step-by-step explanation:

There are 3 triangles total in the figure shown, one large triangle, and two smaller triangles created by the segment BC. Now, look at triangle ACD and see that is a scaled version of common right triangle.

Some common right triangles are 3-4-5, 5-12-13, and 7-24-25. You may be able to see a pattern here where the square of the smallest side length is equal to the sum of the other two side lengths. Triangle ACD happens to be a scaled form of a 5-12-13 triangle. The triangle is scaled by a factor of 3. So the respective side length of AD is 12 * 3 = 36.

Now look at triangle ABD. We have two of the three side lengths.

AD = 36

AB = 85

We want to find BC, so we will use the pythagorean theorem, with (x + 15) to represent the length of BD.

35² + (x + 15)² = 85²

1225 + (x + 15)² = 7225

(x + 15)² = 6000

x + 15 = ±√6000

x = -15 ± √6000

Our equation provides two answers, but the negative value doesn't make sense because length can't be negative, so use the positive length for this application.

x = -15 + √6000

x = 62.4596

Rounded to the nearest whole number, the length of BC is 62.

The diagram shows a square-based cuboid. 4 cm by 10.Work out the volume of the cuboid. State the units of your answer. ​

Answers

Answer:

Step-by-step explanation:

The volume of a square-based cuboid is given by the formula:

V = l × w × h

where l is the length, w is the width, and h is the height of the cuboid.

If the length is 4 cm, the width is also 4 cm (since it is a square-based cuboid), and the height is 10 cm, we can substitute these values into the formula and calculate the volume:

V = 4 cm × 4 cm × 10 cm

V = 160 cubic centimeters (cm³)

Therefore, the volume of the square-based cuboid is 160 cubic centimeters.

Answer:

Step-by-step explanation:

Unfortunately, I cannot see the diagram you are referring to. However, I can provide you with the formula for calculating the volume of a square-based cuboid.

The volume of a square-based cuboid is calculated by multiplying the length, width, and height of the cuboid together. In other words:

Volume = length x width x height

So if the length of the cuboid is 4 cm, the width is also 4 cm (since it is a square-based cuboid), and the height is 10 cm, the volume can be calculated as:

Volume = 4 cm x 4 cm x 10 cm

Volume = 160 cubic centimeters

Therefore, the volume of the cuboid is 160 cubic centimeters (cc), or cm^3.

ΔABC is similar to [tex]~[/tex]ΔADE. BC= 162 and m∠ACB≈ 67.86°

What it similarity of triangles?

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

In  ΔABC and [tex]~[/tex]ΔADE,

m∠ADE=m∠ABC=90⁰

m∠EAD=m∠CAB...(common angle)

Thus, ΔABC is similar to [tex]~[/tex]ΔADE, by AA test of similarity.

What are the properties on similar triangles?

Corresponding angles of both the triangles are equal, and

Corresponding sides of both the triangles are in proportion to each other.

In  ΔABC and [tex]~[/tex]ΔADE,

To find the value of x, we can cross-multiply the given equation and solve for x:

AE/AC=DE/BC

230/315 = 120/BC

Multiplying both sides by BC, we get:

230BC/315 = 120

Multiplying both sides by 315, we get:

230BC = 120 * 315

Dividing both sides by 230, we get:

BC= (120 * 315) / 230

Simplifying, we get:

BC= 162

What is Cosine of an angle?

The cosine of an angle in a right triangle equals the adjacent side divided by the hypotenuse.

In ΔABC

Cos ∠ACB=BC/AC

Cos ∠ACB=162/315

We can use the inverse cosine function (cos⁻¹) to find the measure of angle ACB:

∠ACB= cos⁻¹(162/315)

Using a calculator, we get:

∠ACB ≈ 67.86°

Therefore, the measure of angle ACB is approximately 67.86 degrees.

Round your answer to the nearest hundredth.

Answers

the area of the larger sector is approximately 7.11 m².

How to solve and what does circle mean?

To find the area of the larger sector with radius 8m and central angle 40°, we can use the formula:

Area of sector = (central angle/360) x πr²2

Plugging in the given values, we get:

Area of sector = (40/360) x π(8)²2

Area of sector = (1/9) x 64π

Area of sector = 7.11 m² (rounded to the nearest hundredth)

Therefore, the area of the larger sector is approximately 7.11 m².

A circle is a closed two-dimensional geometric shape consisting of all points that are at the same distance from a fixed point called the center. The distance from the center to any point on the circle is called the radius, and twice the radius is called the diameter. The circumference of a circle is the distance around its edge, and the area of a circle is the space enclosed within its edge.

Simplify 1. 7a^10 - 112a^2 completely

Answers

Answer:

7a^2(a^4 + 4)(a^4 - 4)

Step-by-step explanation:

To simplify 7a^10 - 112a^2, we need to find the greatest common factor (GCF) of the two terms and factor it out.

The GCF of 7a^10 and 112a^2 is 7a^2.

So, we can factor out 7a^2 from both terms, which gives:

7a^2(a^8 - 16)

Now, we can further simplify the expression by noticing that a^8 - 16 is a difference of squares. We can write it as:

a^8 - 16 = (a^4)^2 - 4^2 = (a^4 + 4)(a^4 - 4)

Therefore, the fully simplified expression is:

7a^2(a^4 + 4)(a^4 - 4)
