10 POINTS! Please help ASAP<br><br> How do I find the perimeter of a trapezoid?

KengaRu [80]

Use the triangle formed by the height of the trapezoid to find the lengths of the two sides of the trapezoid and the length of b2:

tan(60)=oppositeadjacent . Adjacent=5tan(60)=2.89 cm.

This finds the base of the triangle, which can be added twice to b1 to find b2: b2=8+2.89+2.89=13.78 cm.

Now, use the same triangle to find the length of the sides.

sin(60)=oppositehypotenuse . Hypotenuse=5sin(60)=5.77 cm.

Lastly, add all of the lengths together: b1+b2+2(l)=8+(2.78+2.78+8)+2(5.77)=33.32 cm.

Find the inverse of each function. Is the inverse a function? y=(x+4)³-1

tatuchka [14]

Inverse of the give function F(x) = ( x + 4 )³ - 1 is F⁻¹(x) = [√( x + 1 ) ] - 4.

Given is a function of x, F(x) = ( x + 4 )³ - 1

These question can be solved by following 4 easy steps

Step 1 : Switch the F(x) with the variable y

This implies, F(x) = ( x + 4 )³ - 1 becomes y = ( x + 4 )³ - 1

Step 2 : Interchange the variable x and y in the above obtained equation

This implies, from the equation y = ( x + 4 )³ - 1, we get

x = ( y + 4 )³ - 1

Step 3 : Solve the new obtained equation for y

This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.

x = ( y + 4 )³ - 1

=> x + 1 = ( y + 4 )³

=> (y + 4 )³ = x + 1

=> y + 4 = √( x + 1 )

=> y = √( x + 1 ) - 4

Hence we obtain the required equation.

Step 4 : Switch the variable y with F⁻¹(x)

This implies, y = √( x + 1 ) - 4 becomes F⁻¹(x) = √( x + 1 ) - 4

Therefore, we get the inverse of the give function F(x) = ( x + 4 )³ - 1 as F⁻¹(x) = [√( x + 1 ) ] - 4.

Question 5Ginny has $10,000 in a savings account earning 4% simple interest annually. Ginny plans on savingthis money for a long

Igoryamba

ANSWER

$18,000

EXPLANATION

Ginny has $10,000 in a savings account.

The interest is 4% simple interest.

We want to calculate Ginny's total account balance after 20 years.

To do this, we will first caluclate the interest and then we will add it to the initial balance.

To calculate Simple Interest, we use:

$\text{Simple Interest = }\frac{P\cdot\text{ R }\cdot\text{ T}}{100}$

P = principal = $10000

R = rate = 4%

T = time = 20 years

Therefore:

$SI\text{ = }\frac{10000\cdot\text{ 4 }\cdot\text{ 20}}{100}\text{ = \$8000}$

Therefore, her account balance after 20 years is:

Amount = $10000 + $8000 = $18,000
