Answer:

Option B is the correct answer.

Step-by-step explanation:

[tex]f(x)=27\bigg(\frac{1}{3}\bigg)^x[/tex] matches the table.

• When x = 0

[tex]\implies f(x)=27\bigg(\frac{1}{3}\bigg)^0= 27*1=27[/tex]

•When x = 1

[tex]\implies f(x)=27\bigg(\frac{1}{3}\bigg)^1= 27*\frac{1}{3}=9[/tex]

•When x = 2

[tex]\implies f(x)=27\bigg(\frac{1}{3}\bigg)^2= 27*\frac{1}{9}=3[/tex]

•When x = 3

[tex]\implies f(x)=27\bigg(\frac{1}{3}\bigg)^3= 27*\frac{1}{27}=1[/tex]

•When x = 4

[tex]\implies f(x)=27\bigg(\frac{1}{3}\bigg)^4= 27*\frac{1}{81}=\frac{1}{3}[/tex]

Answers

Answer:

Step 1) P = 600, Decimal format: 0.04, Balance = 624

Step 2) Principle = 624, Balance = 648.96

Step 3) Principle = 648.96, Balance = 674.92

Step-by-step explanation:

Use the formula of A = P(1 + r/n)^n*t

P = 600, r = 4%, n = 1, t = 1 years.

Plug in

A = 600(1 + 0.04/1)^1*1

A = 600 * 1.04^1

A = 600 * 1.04

A = 624

To find the seperate interest

A = P + I

624 = 600 + I

I = 624 - 600

I = 24

Repeat for Step 2

P = 624, r = 4%, n = 1, t = 1

A = 624(1 + 0.04/1)^1*1

A = 624 * 1.04^1

A = 624 * 1.04

A = 648.96

Repeat for interest

648.96 = 624 + I

I = 648.96 - 624

I = 24.96

Repeat for step 3

A = 648.96, r = 4%, n = 1, t = 1

A = 648.96(1 + 0.04/1)^1*1

A = 648.96 * 1.04^1

A = 648.96 * 1.04

A = 674.92

Interest repeat

674.92 = 648.96 + I

I = 674.92 - 648.96

I = 25.96

A normal distribution (X) has a mean of 100 and a standard deviation of 10.

What is the x value that is the third quartile for this distribution?

Round your answer to the first decimal position.

Answers

The x value for the third quartile for this distribution is 106.8

Z score

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

where μ is the mean, x = raw score and σ is the standard deviation.

Given μ = 100, σ = 10.

The third quartile correspond with a z score of 0.675, hence:

0.675 = (x - 100) / 10

x = 106.8

The x value for the third quartile for this distribution is 106.8

I THINK!!!!!! (x, y) = (-4, -25) im not completely sure tho

Step-by-step explanation:

substitute y = 7x + 3 in equation 2

9x - 2y = 14

9x - 2(7x + 3) = 14

9x - 14x + 6 = 14

-5x + 6 = 14

-5x = 14 - 6

x = 8 ÷ 5

x = 1.6

subs x = 1.6 into equation 1

y = 7x + 3

y = 7(1.6) + 3

y = 11.2 + 3

y = 14.2

(0,-6)
(3,0)
(-6,0)

Answers

Answer:

-6

Step-by-step explanation:

x-intercept is y = 0, so the point is (-6, 0), answer is -6

The Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).

What is Intercept?

The term "intercept" refers to the location where a line or curve crosses a graph's axis. The x-intercept is the point at which the x-axis is crossed. The y-intercept is the point at which the y-axis is crossed.

The x- or y-axis intersection point is what is meant when a line has an intercept. The y-axis is often taken into account if the axis is not stated. The letter "b" is typically used to represent it.

We know that the x intercept can be find where the value of y=0

So, From the table attached,

For x = -1, f(-1) = 0

For x = 2, f(2) = 0

For x = 3, f(3) = 0

Thus, Points (-1, 0), (2, 0) and (3, 0) are the x-intercepts of the function f(x).

Suppose you have invested $1500 at an APR of 8%. Use the Rule of 72 to estimate how long it will be until your investment reaches $3000.

Answers

Answer:

25 Years. thank you for your question

The time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.

What is the Rule of 72?

The rule of 72 is the easy way to calculate the number of years required the investment with the given interest rate. It can be calculated as,

[tex]t\approx\dfrac{72}{r}[/tex]

Here, (t) is the time period and (r) is the rate of return.

The invested amount is $1500 and the value of APR is 8%. The time we have to calculate using the rule of 72.

The final amount of the investment is $3000 which is double the initial amount. Thus, the time period required to double the investment with 8% of interest is,

[tex]t\approx\dfrac{72}{8}\\t\approx9[/tex]

Thus, the time required for the investment of $1500 reaches $3000 with APR of 8% using the rule of 72 is 9 years.

-3,2 and 8,2 in slope intercept form

Answers

Answer:

y = 2

Step-by-step explanation:

So we need to find the slope first.

m = y_2 - y_1/x_2 - x_1

Substitute

m = 2 - (2)/8 - (-3)

Simplify now.

Multiply -1 by 2

m = 2 - 2/(8 - (-3)

2 from 2

m = 0/8 - (-3)

Now we need to simplify the denominator.

To do so lets multiply -1 by -3

m = 0/8 + 3

m = 0/11

m = 0

Now we have the slope of 0 and the given point of (-3, 2)

So y - (2) = 0 * (x - (-3)) (Formula > y - y_1 = m(x - x_1) this comes from the original slope equation]

Simplify further

y - 2 = 0 * (x + 3)

Now we solve for y

Multiply 0 by x + 3

y - 2 = 0

Add 2 to both sides

y = 2
