Answer:

(-3, -34)

Step-by-step explanation:

I'm assuming g(x) is supposed to by g(x) = 2x² + 12x - 16

The general form for a quadratic function is f(x) = ax² + bx + c

For our equation, a = 2, b = 12 and c = -16

The formula for the x coordinate of the vertex is

x = -b/(2a)

Plug in our values and simplify...

x = -12/(2*2) = -12/4 = -3

Plug that value into g(x) to find the y coordinate of the vertex:

g(-3) = 2(-3)² + 12(-3) - 16

  g(-3) = 2(9) - 36 - 16

     g(-3) = -34

In the diagram, BC is a radius of C. Determine whether AB is tangent to C. Explain your reasoning.
Whitepunk [10]

Answer:

No, AB is not tangent to C.

If it were tangent, it would form a right angle with the radius, and we could use Pythagorean's Theorem.

3²+6²=7²

9+36=49

45=49  Since this is false, it's not a right angle, and AB is not tangent.

Step-by-step explanation:

No, AB is not tangent to C.

If it were tangent, it would form a right angle with the radius, and we could use Pythagorean's Theorem.

3²+6²=7²

9+36=49

45=49  Since this is false, it's not a right angle, and AB is not tangent.

I need to a paint a spherical storage tank in the pool. it has a radius of 8 feet and the paint cans i brought will cover 75 squ
Alexxandr [17]
<h3>Answer:   11 cans</h3>

======================================================

Explanation:

SA = surface area of the sphere

SA = 4*pi*r^2

SA = 4*pi*8^2

SA = 804.247719

The surface area is roughly 804.247719 sq ft.

I used the calculator's stored version of pi to get the most accuracy possible.

Since 1 paint can covers 75 sq ft, divide that surface area over 75 to find out how many cans you need.

804.247719/75 = 10.72330292

Round up to the nearest integer to get 11

You'll have leftover paint, but it's better to go over the goal than come up short.

(Geometry) PLZ HELP ASAP
Marianna [84]

Answer:

121 square feet

Step-by-step explanation:

The area of a triangle is the height multiplied by the base divided by 2. Since this is a right triangle, you can simply use the two legs for this. The area of this triangle is therefore:

\dfrac{24.2\cdot 10}{2}=\dfrac{242}{2}=121

Hope this helps!
