F(x)=3x+2 and g(x)=-2x-4, find h(x)= f(x)-g(x)
Katena32 [7]


substitute for your equation;

h(x) = f(x) - g(x)

h(x) = (3x + 2) - (-2x -4)

h(x) = 3x + 2 + 2x + 4 (minus and minus = addition)

h(x) = 3x + 2x + 2 + 4 (combine like terms)

h(x) = 5x + 6

Hope that helps! :D

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?
Alchen [17]

Answer:

FV= $634.12

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $500

Number of periods (n)= 3*4= 12 quarters

Interest rate (i)= 0.08/4= 0.02

<u>To calculate the future value, we need to use the following formula:</u>

<u></u>

FV= PV* (1 + i)^n

FV= 500*(1.02^12)

FV= $634.12

Elena L [17]

Answer:

Step-by-step explanation:

Confidence interval is written in the form,

(Sample mean - margin of error, sample mean + margin of error)

The sample mean, x is the point estimate for the population mean.

Since the sample size is large and the population standard deviation is known, we would use the following formula and determine the z score from the normal distribution table.

Margin of error = z × σ/√n

Where

σ = population standard Deviation

n = number of samples

From the information given

1) x = 17.5

σ = 5

n = 50

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.9 = 0.1

α/2 = 0.1/2 = 0.05

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.05 = 0.95

The z score corresponding to the area on the z table is 1.645. Thus, confidence level of 90% is 1.645

Margin of error = 1.645 × 5/√50 = 1.16

Confidence interval = 17.5 ± 1.16
