Answer: 251.2 inches.

Step-by-step explanation: You have to multiply 4*2*π*radius. So, simply multiply 4*2*3.14*10. It would come out as 251.2 inches.

Find the slope of the tangent line to the graph of f at the given point. f(x) = x√ at (36,6) 1/3 1/12 3 12

Alik [6]

slope = $\frac{1}{12}$

the slope is the value of f' (36)

f(x) = √x = $x^{\frac{1}{2} }$

f'(x) = $\frac{1}{2}$ $x^{-\frac{1}{2} }$ = $\frac{1}{2\sqrt{x} }$

f'(36) = $\frac{1}{2(6)}$ = $\frac{1}{12}$

Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.

ycow [4]

This involves quite a lot of arithmetic to do manually.

The first thing you do is to make the first number in row 2 = to 0.

This is done by R2 = -3/2 R1 + R2

so the matrix becomes

( 2 1 1) ( -3 )

( 0 -13/2 3/2) (1/2 )

(5 -1 2) (-2)

Next step is to make the 5 in row 5 = 0

then the -1 must become zero

You aim for the form

( 1 0 0) (x)

(0 1 0) (y)

(0 0 1) ( z)

x , y and z will be the required solutions.

You have decided to purchase a car for $22,346. 16. The credit union requires a 10% down payment and will finance the balance wi

Natali [406]

The amount that the credit union will finance is $24169.60

We have given that the cost of the car is $22,346. 16

and the credit union required 10% down payment

and sale tax=7.6%

The license and title charges are $125. 13.

We have to determine that the amount that the credit union will

finance Now we have sale tax 7.6% for $22,346. 16

Therefore, we get

$\frac{7.6}{100} \times 22,346. 16=1698.31$

<h3>What is the amount that the credit union finance ?</h3>

credit union finance=cost of car+sales tax+the license and title charges.

$=22346.16+1698.31+12.13\\=24169.60$

Therefore, the amount that the credit union will finance is $24169.60
