Answer:

The area of the base is 12.56 units squared.

Step-by-step explanation:

The volume formula of a cone is [tex]\pi r^{2} \frac{h}{3}[/tex]. To solve for the base area, just multiply the volume by 3 and divide by the height. 25.12 * [tex]\frac{3}{6}[/tex] = [tex]\frac{25.12}{2}[/tex] = 12.56 units squared.

Use the function f(x) = 2 sin x-1 to identify the following.

Answers

Answer:

See below for answers

Step-by-step explanation:

Do you mean [tex]f(x)=2sin(x-1)[/tex] or [tex]f(x)=2sin(x) -1[/tex]?

Use the formula [tex]f(x)=asin(bx+c)+d[/tex] where [tex]|a|[/tex] is the amplitude, [tex]-\frac{c}{b}[/tex] is the phase shift, [tex]d[/tex] is the vertical shift, and the period is [tex]\frac{2\pi}{|b|}[/tex].

Assuming your first case is true, the amplitude would be [tex]|a|=|2|=2[/tex], your period is [tex]\frac{2\pi}{|1|}=2\pi[/tex], and your midline/vertical shift is [tex]d=0[/tex].

Assuming your second case is true, everything but the vertical shift stays the same. It would be [tex]d=-1[/tex] in this case.

A line with a slope of -2 is written in the form y=mx+b.
what is the value of b If the line passes through the point (5,-7)?​

Answers

Answer:

b = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Here m = - 2 , then

y = - 2x + b ← is the partial equation

To find b substitute (5, - 7 ) into the partial equation

- 7 = - 10 + b ⇒ b = - 7 + 10 = 3

You want to create a scale model for a building that will be 120feet tall and 40 feet wide. If you make the model 6 feet tall, how wide should it be?

Answers

Given:

Length of the building  = 120 feet

Width of the building = 40 feet

Length of the model = 6 feet

To find:

Width of the model.

Solution:

The scale model similar to the original figure and the corresponding sides of the similar figures are proportional.

Let x be the width of the building.

[tex]\dfrac{\text{Length of the building}}{\text{Length of the model}}=\dfrac{\text{Width of the building}}{\text{Width of the model}}[/tex]

[tex]\dfrac{120}{6}=\dfrac{40}{x}[/tex]

[tex]20=\dfrac{40}{x}[/tex]

[tex]x=\dfrac{40}{20}[/tex]

[tex]x=2[/tex]

Therefore, the width of the model is 2 feet.

You can afford a $800 per month mortgage payment. You've found a 30 year loan at 7% interest.
a) How big of a loan can you afford?
$
b) How much total money will you pay the loan company?
c) How much of that money is interest?

Answers

a) You can afford a loan of approximately $96,927.88.

b) You will pay a total of $288,000 to the loan company.

c) Approximately $191,072.12 of that money is interest.

To determine how big of a loan you can afford, we can use the formula for the monthly mortgage payment:

M = P * (r(1+r)^n) / ((1+r)^n - 1)

Where M is the monthly mortgage payment, P is the loan principal, r is the monthly interest rate (annual interest rate divided by 12), and n is the total number of payments (number of years multiplied by 12).

a) First, we need to calculate the monthly interest rate and the total number of payments:

Monthly interest rate = 7% / 12 = 0.07 / 12 = 0.00583

Total number of payments = 30 years * 12 months/year = 360

Now we can plug in the values into the formula:

800 = P * (0.00583 * (1+0.00583)^360) / ((1+0.00583)^360 - 1)

To solve for P, we can rearrange the equation:

P = 800 * ((1+0.00583)^360 - 1) / (0.00583 * (1+0.00583)^360)

Using a calculator, we find that P is approximately $96,927.88.

b) To calculate the total money paid to the loan company, we multiply the monthly payment by the total number of payments:

Total money paid = $800 * 360 = $288,000

c) To determine how much of that money is interest, we subtract the loan principal from the total money paid:

Interest = Total money paid - Loan principal

Interest = $288,000 - $96,927.88

Interest = $191,072.12

Step-by-step explanation:

99+72=171

For the expression 99 + 72 = 9 (11 + x) the value of x is 8.

What are mathematical operations?

Calculate the answer using a math operator is referred to as a mathematical operation.

Basic mathematical operations are addition, multiplication, subtraction and division.

The given expression is,

99 + 72 = 9 (11 + x)

To find the value of x, simplify the expression by using mathematical operations,

171 = 9 (11 + x)

171 / 9 = 11 + x

19 = 11 + x

19 - 11 = x

8 = x

x = 8

The required value of x is 8.

Given that h varies inversely with respect to g, and that h= -24 when g= 3, write an
equation that describes the relationship between h and g. Then find h when g=-1,

Answers

Answer:

h = 72

Step-by-step explanation:

Given that h varies inversely with g then the equation relating them is

h = [tex]\frac{k}{g}[/tex] ← k is the constant of variation

To find k use the condition h = - 24 when g = 3 , then

- 24 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )

- 72 = k

h = - [tex]\frac{72}{g}[/tex] ← equation of variation

When g = - 1 , then

h = - [tex]\frac{72}{-1}[/tex] = 72
