Find the coordinates of the point 3/10
of the way from A to B.

Answer: 46

Step-by-step explanation:

Since we know that angles J and E are congruent, we can do the equation 6x + 4 = 2x +32. We then solve for x which gives us 7. After that, we plug in the 7 into the equation for E which would be = 2(7) + 32. Once we solve that, we end up with 46.

Answer:

181

Step-by-step explanation:

Sally is running laps around a track. She runs 12 laps to warm up. Then she runs 13² laps.

First write the equation. we know she alr ran 12 laps so its going to be +12

to 13^2. so the equation will be 12+13^2 then using PEMDAS we know that we have to do the exponents first so 13^2 is just 13 * 13 which is 169. so now the equation is 169+12 now just add. the answer is 181

Answer:

B=30°

Step-by-step explanation:

Recall that the sum of interior angles of a triangle equals to 180°. So basically

[tex]A+B+\alpha+\beta=180^{\circ}[/tex]

[tex] \implies B + {70}^{ \circ} + {80}^{ \circ} = {180}^{ \circ} \\ \implies B = {180}^{ \circ} - {150}^{ \circ} \\ \implies B = \boxed{{30}^{ \circ} }[/tex]

[tex]x^4+4x^3-8x-32=0[/tex]  

Can be factoried into:

[tex](x^3-8)(x+4)=0\\[/tex]

Now you're looking for which values of x will make the equations in the brackets equal to 0, since as long as one is equal to 0, they will be multiplied into 0.

First we'll do:

[tex]x^3-8=0[/tex]

We're looking for what number cubed is equal to 8, which is 2.

Note: -2 is also a possibility, but if you plug it in, you'll see that it doesn't work.

Second we'll do:

[tex]x+4=0[/tex]

This one's pretty easy, x will be -4.

So your solutions are:

x = 2, -4

The solutions of the polynomial [tex]x^{4}[/tex] + 4x³ - 8x - 32 = 0 are 2 and -4.

Polynomials are sums of terms of the form k⋅xⁿ.

where k is any number

n is a positive integer.

Example:

2x + 4x - 7 is a polynomial

We have,

[tex]x^{4}[/tex] + 4x³ - 8x - 32 = 0 _______(1)

Divide into two parts.

[tex]x^{4}[/tex] + 4x³

-8x - 32

Take out the common from each part.

x³ ( x + 4 )

- 8 ( x  + 4 )

Now,

We have,

x³ ( x + 4 ) - 8 ( x  + 4 ) = 0

We can write this as:

(x³ - 8) (x + 4) = 0

Now,

We need to find the x values.

x³ - 8 = 0

x³ = 8

x = ±2

Put x = 2 in (1)

[tex]x^{4}[/tex] + 4x³ - 8x - 32 = 0

x = 2

16 + 32 - 16 - 32

0 = 0

x = 2 is satisfied

Put x = -2 in (1)

16 - 32 + 16 - 32 = 0

-64 ≠ 0

x = -2 is not satisfied

x + 4 = 0

x = -4 putting in (1)

256 - 256 + 32 - 32 = 0

0 = 0

x = -4 is satisfied

Thus the solutions of the polynomial [tex]x^{4}[/tex] + 4x³ - 8x - 32 = 0 are 2 and -4.

Step-by-step explanation:

The missing number (x) from the sequence → 11, 29, 11, x  is 17.

We have the mean of given set of numbers.

We have to identify the missing number.

The mean in math and statistics summarizes an entire dataset with a single number representing the data's center point or typical value. It is calculated  using the formula -

Mean (M) = ∑a[i] / n

where -  

∑a[i] = sum of the elements in a data set

n = total number of elements

According to the question - assume that the missing number is x. Then, we have -

11, 29, 11, x

Now, using the formula of mean -

M = ∑a[i] / n

17 = (11 + 29 + 11 + x)/4

68 = 51 + x

x = 68 - 51

x = 17

Therefore, the missing number is 17.

The value of x is 52° and the value of y is 104 ° as calculated using the chord properties of a circle.

A circle is defined as the locus of a moving point such that the distance of the point from a fixed point is always same.

In the given figure AC is the diameter of the circle.

We know that the  angle subtended by the chord is always 90°.

∴∠CBA = 90°

Now in ΔABC

∠ABC+∠BCA+ ∠CAB =180° (sum of all angles of a triangle is always 180°)

or, 90° + 38° + x° = 180°

or, 128° + x° =180°

or, x = 52°

Again in ΔDBC ,

DB=DC (radius of the circle)

∴∠DCB = ∠DBC (base angles of an isosceles triangles are equal)

∴∠DBC = 38°

Again in ΔDBC

∠DBC+∠BCD+ ∠CDB = 180° (sum of all angles of a triangle is always 180°)

or, y =  180° - 76°

or, y = 104°

Therefore the value of x is 52° and the value of y is 104 ° .

Answer:

y = 2x +4

Step-by-step explanation:

Equation of a line in slope-intercept form is

y = mx + b

where m is the slope and b is the y-intercept, the point at which the line crosses the y axis (at x = 0)

Given slope is 2 we get the equation as

y = 2x + b

We have to solve for b by plugging in the x and y values for point(1,6)

Thus we get y = 6 = 2(1) + b

Or 6 = 2 + b

b= 6-2 = 4

Equation in slope-intercept form is

so, we need to add 3 to x within the function to move it left by units.

i.e

[tex]\qquad \sf  \dashrightarrow \: y = |x + 3| [/tex]

Now, to move it down by 4 units we need to subtract 4 from the whole function.

[tex]\qquad \sf  \dashrightarrow \: y = |x + 3| - 4[/tex]

So, the correct choice is : C

the required can be transformed by moving at 3 units left and 4 units down do you understand ? after that are 3 and x

y = x + 3

now to move it down by 4 units we need to subtract for from the whole function which is y is equal to x + 3 - 4

y = |x+3| - 4

Aaron Smith would has average hits per baseball game as 0.79  hits per game.

Average provides ill information in case of skewed data.

Arithmetic mean is the best central measure available for representing the values of a data set.  It is also called average of the values of the considered data set. It serves as predicted value(in case no other information of the data is available) of that data set.

WE have been given that After 30 baseball games Aaron Smith had 24 hits. If after 100 games he had 80 hits, then he would has average hits per baseball game;

Average  = Hits in game / number of games

Average  = 24- 80 / 30-100

Average  =  56 / 70

Average  = 0.79  hits per game

Hence, Aaron Smith would has average hits per baseball game as 0.79  hits per game.

Answer:

y = - x + 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x + 5 ← is in slope- intercept form

with slope m = - 1

• Parallel lines have equal slopes , then

y = - x + c ← is the partial equation of the parallel line

to find c substitute (3, - 2 ) into the partial equation

- 2 = - 3 + c ⇒ c = - 2 + 3 = 1

y = - x + 1 ← equation of parallel line

Answer: range = 16 standard deviation = 5

Step-by-step explanation:

Answer:

Step-by-step explanation:

You are given the solution to a 2-step linear equation and asked to identify the properties of equality and operations that support the steps of the solution.

5(x -3) = 20 . . . . This is the Given equation we're solving.

(1/5)(5(x -3)) = (1/5)(20) . . . . Both sides are multiplied by 1/5. The Multiplication property of equality says you can do this without changing the value of the variable.

1(x -3) = 4 . . . . (1/5)(5) is replaced by 1. The Multiplicative inverse property tells you the product of a number and its multiplicative inverse is 1.

x -3 = 4 . . . . 1(x -3) is replaced by (x -3). The Multiplicative identity property tells you multiplication by 1 changes nothing. These properties of multiplication are what allow you to remove the factor of 5 from the equation.

Now, we're about to do the same thing with addition: use its properties to remove the unwanted -3.

x -3 +3 = 4 +3 . . . . 3 is added to both sides. The Addition property of equality says you can do this without changing the value of the variable.

x +0 = 7 . . . . -3+3 is replaced by 0. The Additive inverse property tells you the sum of a number and its additive inverse is zero.

x = 7 . . . . x+0 is replaced by x. The Additive identity property tells you addition of 0 changes nothing. These properties of addition are what allow you to remove the added -3 from the equation.

__

Additional comment

Clearly, for exercises like this, it is essential to know the names of these properties and what they mean. Once you understand cancelling multiplication using multiplicative inverses, and cancelling addition using additive inverses, you are on your way to solving most algebra problems.

You must always keep in mind the properties of equality that tell you the same operation must be performed on both sides of the equal sign.

Understanding these properties can also help you understand the relation between multiplication and division, addition and subtraction. Division is multiplication by the multiplicative inverse; subtraction is addition of the additive inverse.

The interest rate required to get a total amount of $3,688.86 from compound interest on a principal of $2,000.00 compounded 12 times per year over 5 years is 12.306% per year.

Given,

The total amount (A)= $3688.86

Principal (P) = $2000

time period (t) = 5 years.

compounded monthly (n) = 12

rate of interest per year = ?

we know that r=n[(A/P)¹/ⁿt  -1]

substitute the above values.

r = 12 × [(3688.86/2000)¹/⁽¹²⁾⁽⁵⁾ - 1]

r = 12 × [(1.84443)¹/⁶⁰ - 1]

r = 12 × 0.0102

r = 0.12306

Now convert r to R as a percentage.

R = r × 100

R = 0.12306 × 100

R = 12.306%

Hence the rate of interest compounded monthly is 12.306%
