A right cylinder has a radius of 3 and a height of 12. What is its surface area? O A. 72 units O B. 90 units O c. 45rt units O D. 108r units​

Answers

Answer 1

Answer:

[tex]A=72\pi\ units^2[/tex]

Step-by-step explanation:

Given that,

The radius of the cylinder, r = 3

Height of the cylinder, h = 12

We need to find the surface area of the cylinder. The formula for the surface area of a cylindrical object is given by :

[tex]A=2\pi rh\\\\=2\times \pi\times 3\times 12\\\\=72\pi\ units^2[/tex]

So, the surface area of the cylinder is equal to [tex]72\pi\ units^2[/tex].

When the new principal on a loan is $79,946.13 and the interest rate is 8 percent, the monthly payment is $587.20. Find the interest, the payment to principal, and the new balance. STEP 1: Find the interest.

Answer:

to interest: $532.97to principal: $54.23new balance: $79,891.90

Step-by-step explanation:

The interest is found by multiplying the monthly rate by the balance on the loan. For the first month, the balance is the loan amount.

  $79,946.13 × 0.08 ×(1/12) . . . . . one month = 1/12 year

  = $532.97

The interest amount in the first payment is $532.97.

__

The amount of the first payment that goes to principal is what is left after the interest is paid:

  $587.20 -532.97 = $54.23 . . . amount to principal

__

The new balance is the previous balance less the amount to principal:

  $79,946.13 -54.23 = $79,891.90 . . . new balance

Find the surface area of the square pyramid:​

Answers

Here's the solution,

Area of Square pyramid = Areas of triangles + Area of square base

and we know, the triangles have equal base and same height, so their areas will be equal

Area of each triangle :

=》

[tex] \dfrac{1}{2} \times 9 \times 7[/tex]

=》

[tex] \dfrac{63}{2} [/tex]

=》

[tex]31.5[/tex]

So, are of triangle = 31.5 ft²

since, there are four triangles ,

Area = 31.5 × 4

=》126 ft²

Area of square base = 9 × 9 = 81 ft²

Hence, Area of pyramid = 81 ft² + 126 ft²

=》207 ft²

Answers

Answer:

Root at -4 with multiplicity of 2

Root at 2 with multiplicity of 1

Step-by-step explanation:

You don't actually need to factor this, you can just use Vieta's formulas and deduce the answer by looking at the options.

It states that the product of the roots is equal to the constant over the coefficient of the highest degree term; in this case, it is 16/1=16.

If you take the product of the roots of each answer, you get (from top to bottom) 16, 4, -16, and -4, which means that only the first answer is correct.

Which of the following equations has a solution of x = -5?

Answers

Answer:

B

Step-by-step explanation:

16(-5) - 7 = 11(-5) - 32

-80 - 7 = -55 - 32

-87 = -87

-4(-5) - 10 = 2(-5) + 20

-30 ≠ 10

Answer:

c. Both A and B

Step-by-step explanation:

Let's solve the equations to find out.

Equation A

16x - 7 = 11x - 32

5x - 7 = -32

5x = -25

x = -5

So, Equation A has a solution of x = -5.

Equation B

-4x - 10 = 2x + 20

-6x - 10 = 20

-6x = 30

x = -5

And so does Equation B.
