Answer:

Because I don't know exactly which form you need here is the same answer $ ways

x= 6/12

x= 1/2

x= .5

x=50%

Step-by-step explanation:

Your solving for x so here is how you do it:

4(3x-2)+2^3=6

12x-8+2^3=6

12x-8+8=6

12x=6 (because the 8s cancel each other out)

x= 6/12= 1/2= .5 =50%

Solve for x. show your work.

Hello!

$\large\boxed{x = 8}$

The two angles pictured are corresponding angles, so they are congruent.

Therefore:

17x - 4 = 12 + 15x

Isolate for x by subtracting 15x from both sides:

2x - 4 = 12

Add 4 to both sides:

2x = 16

Divide both sides by 2:

x = 8.

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of

ale4655 [162]

Answer: 4 seconds

Step-by-step explanation:

Given: The function $h(t)=-36t^2+288t+9$ can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.

Differentiate the given function with respect to t , we get

$h'(t)=-36(2)t+288=-72t+288$

Put h'(t)=0

$\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4$

Also, $h''(t)=-72$

By second derivative test, h(t) is maximum at t=4.

Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
