what is the nth term a_(n) of the geometric sequence with a_(1)=4 r=(1)/(2) and n=5

Answers

Answer 1

1/4

The nth term of a geometric sequence can be found using the formula:

a_(n) = a_(1) * r^(n-1)

where a_(1) is the first term of the sequence and r is the common ratio.

Given a_(1) = 4, r = 1/2, and n = 5, we can substitute these values into the formula to get:

a_(5) = 4 * (1/2)^(5-1)

= 4 * (1/2)^4

= 4 * (1/16)

= 1/4

Therefore, the 5th term of the geometric sequence is a_(5) = 1/4.

Knowledge Check Questio Calculate the distance between the points C=(-7,6) and E=(-2,2)

Answers

The distance between the points C=(-7,6) and E=(-2,2) is 6.4 units.

To calculate the distance between two points, we use the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

In this case, the points are C=(-7,6) and E=(-2,2), so we can plug in the values into the formula:

d = √((-2 - (-7))^2 + (2 - 6)^2)

d = √((5)^2 + (-4)^2)

d = √(25 + 16)

d = √(41)

d = 6.4

Therefore, the distance between the points C=(-7,6) and E=(-2,2) is 6.4 units.

According to the graph

B Solve the following showing all steps \( 5 \quad \log _{2}(32)=x \) \( 6 \log _{2}(x-4)+\log _{2}(x)=5 \)

Answers

To solve this problem, use logarithmic properties to combine the two equations into one.


First, use the product rule to combine the two equations:
$\log_2(32) + \log_2(x-4) + \log_2(x) = 5$
Then use the power rule to combine the last two terms:
$\log_2(32) + \log_2(x^2 - 4x) = 5$
Finally, use the quotient rule to separate the terms:
$\log_2\frac{32}{x^2 - 4x} = 5$


To solve for $x$, take the inverse logarithm of both sides:
$\frac{32}{x^2 - 4x} = 2^5$
Expand and simplify the left side to get a quadratic equation:
$x^2 - 4x - 32 = 0$
Solve the quadratic equation using the quadratic formula:
$x = \frac{4 \pm \sqrt{4^2 + 4(32)}}{2}$
$x = \frac{4 \pm \sqrt{136}}{2}$
$x = 4 \pm \sqrt{17}$


Therefore, the solutions are:
$x = 4 + \sqrt{17}$
$x = 4 - \sqrt{17}$

a) Determine if f is continous from the left at x =0
b) Determine if f is continous from the right at x =0
c) Determine if f is continous at f = 0

Answers

"f " is continuous at x = 0.

a) To determine if f is continuous from the left at x = 0, we need to evaluate the limit of f(x) as x approaches 0 from the left. This means we need to use the first piece of the function, x + sin x, since this is the piece that applies when x < 0:

lim(x->0-) f(x) = lim(x->0-) (x + sin x) = 0 + sin 0 = 0

Since the limit exists and is equal to the value of the function at x = 0 (which is 2), f is continuous from the left at x = 0.

b) To determine if f is continuous from the right at x = 0, we need to evaluate the limit of f(x) as x approaches 0 from the right. This means we need to use the third piece of the function, 2/(1+x^2), since this is the piece that applies when x > 0:

lim(x->0+) f(x) = lim(x->0+) (2/(1+x^2)) = 2/(1+0^2) = 2

Since the limit exists and is equal to the value of the function at x = 0 (which is 2), f is continuous from the right at x = 0.

c) To determine if f is continuous at x = 0, we need to make sure that the limits from the left and right both exist and are equal to each other and to the value of the function at x = 0. We already found that the limits from the left and right are both equal to 2, which is also the value of the function at x = 0. Therefore, f is continuous at x = 0.

Irons is trying to lay out the bases for a game of kickball such that the infield is a square as shown. She would like bases to be 25 feet apart. She first placed home base and then places first and third base 25 feet from home base
How far to the nearest tenth of a foot should first base and third base be from each other justify.

Answers

The answer of the given question based on the Irons is trying to lay out the bases for a game of kickball such that the infield is a square the answer is  first base and third base should be about 35.4 feet apart.

What is Pythagorean theorem?

The Pythagorean theorem is  fundamental concept in geometry that relates to three sides of right triangle. It states that in right triangle, the square of  length of  hypotenuse (the side opposite the right angle) is equal to  sum of the squares of  lengths of other two sides.

We can use the Pythagorean theorem to find this distance.

Let's call the distance between home base and first base "a". We know that the distance between home base and third base is also "a", because the infield is a square. We also know that the distance between home base and second base (which is the hypotenuse of the right triangle formed by home base, first base, and second base) is 25 feet.

Using the Pythagorean theorem, we can solve for "a":

a² + 25² = a² + a²

2a² = 25²

a² = (25²)/2

a = sqrt((25²)/2) ≈ 17.7 feet

So the distance between first base and third base should be approximately 35.4 feet (2a). Rounding to the nearest tenth of a foot, this is 35.4 feet. Therefore, first base and third base should be about 35.4 feet apart.

What is an exponential function?

An exponential function is a mathematical function of the form f(x) = a^x, where a is a positive constant and x is a variable. The base a is usually a number greater than 1, although it can be any positive number.

Exponential functions have a distinctive characteristic that sets them apart from other types of functions: the value of the function increases or decreases exponentially as the value of x increases or decreases. In other words, the rate of change of the function is proportional to its current value, which results in a rapid growth or decay.

We have that;

p(t) = 1000e^0.042t

p(t)/1000 = e^0.042t

Jason earns $232.50 per week as the manager at Big Bucks Department Store. He is single and claimed
1 allowance last year. How much more will be deducted from his weekly check if he claims no
allowances?

Answers

If Jason claims no allowances this year, $17 more will be deducted from his weekly check for taxes compared to last year when he claimed one allowance.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

The amount of money deducted from Jason's paycheck for taxes depends on the number of allowances he claims.

Claiming more allowances reduces the amount of taxes withheld from his paycheck while claiming fewer allowances increases it.

If Jason claimed 1 allowance last year, his employer would have withheld taxes from his paycheck based on that information.

If he claims no allowances this year, more taxes will be withheld.

To calculate how much more will be deducted from his weekly check if he claims no allowances, we need to know his tax bracket and the amount of taxes that will be withheld for each allowance.

Assuming Jason is paid on a weekly basis, we can use the IRS tax withholding tables for 2021 to estimate the additional amount of taxes that will be withheld if he claims no allowances.

Using these tables, we find that for a single person earning $232.50 per week, claiming no allowances would result in an additional withholding of $17 per week.

Therefore, claiming no allowances would result in an additional withholding of $17 per week.

Answers

To solve this problem, we can use a system of equations.

Let's call the number of Php 5 coins x and the number of Php 10 coins y. The first equation will represent the total number of coins: x + y = 120. The second equation will represent the total amount of money: 5x + 10y = 950. Now we can use the elimination method to solve for one of the variables. Let's multiply the first equation by -10 and then add the two equations together:

-10x - 10y = -1200

5x + 10y = 950

-----------------

-5x = -250

Divide both sides by -5 to get x:

x = 50. Now we can plug this value back into the first equation to solve for y:

50 + y = 120

y = 70

So there are 50 Php 5 coins and 70 Php 10 coins.

Answer:

To find the area of the trapezoid-shaped playground, we need to use the formula:

Area = (1/2) × (base1 + base2) × height

In the given diagram, the length of the top base is 24 feet, the length of the bottom base is 48 feet, and the height is 52 feet.

So, the area of the playground is:

Area = (1/2) × (24 + 48) × 52

= (1/2) × 72 × 52

= 1,872 square feet

Therefore, the area of the playground is 1,872 square feet.

The closest option to this answer is option B, which is 1,768 square feet. However, the correct answer is actually 1,872 square feet.

Step-by-step explanation:

for % questions always find 100% and/or 1%.

everything else can be easily calculated out of these 2.

the original price of $210 = 100%, as we want to know how many % the new price is different from that.

100% = $210

1% = 100%/100 = 210/100 = $2.10

the new price is $300.

the difference is 300 - 210 = $90

how many % are $90 compared to the original price ?

well, as many as the times 2.1 (1%) fits into 90 :

90/2.1 = 42.85714286...%

that increase from $210 to $300 was 42.85714286...%.

an additional $50 baggage fee ?

we have to add this to the $300 and get $350 as new price.

that difference is now 350 - 210 = $140.

how many % are $140 compared to the original price ?

140/2.1 = 66.66666666...%

Find all values of m for which the equation has two complex (non-real ) solutions.

Answers

The answer of values of m for which the equation has two complex (non-real) solutions are all values greater than 1/8. In other words, m > 1/8

To find all values of m for which the equation has two complex (non-real) solutions, we need to use the discriminant of the quadratic formula.

The discriminant is the part of the quadratic formula under the square root: b²-4ac. If the discriminant is less than 0, then the equation will have two complex (non-real) solutions.

So, let's start by setting the discriminant to be less than 0:

b²-4ac < 0

Now, let's plug in the values from the equation into the discriminant. The equation is in the form ax²+bx+c=0, so we can plug in the values for a, b, and c:

(1)²-4(m)(2) < 0

Simplify:

1-8m < 0

Subtract 1 from both sides:

-8m < -1

Divide both sides by -8:

m > 1/8

So, the values of m for which the equation has two complex (non-real) solutions are all values greater than 1/8. In other words, m > 1/8.

n = [tex](-9 ± √(9^2-4(1)(18)))/(2(1))[/tex]

n = (-9 ± √(81-72))/2

n = (-9 ± √9)/2

n = (-9 ± 3)/2

The two values of n are:

n = (-9 + 3)/2 = -6/2 = -3

n = (-9 - 3)/2 = -12/2 = -6

So the values of n for which the denominator equals zero are n = -3 and n = -6.
