Answer:
<u>b = -4, 0</u>
Step-by-step explanation:
<u>Given</u> :
<u>Take b as a common factor.</u>
<u>Solutions</u>
- b = 0
- b + 4 = 0 ⇒ b = -4
- <u>b = -4, 0</u>
Don’t you have to flip the sign when you divide by a negative? So I think she’s wrong bc the answer should be d is less than or equal to 7.5
Answer:
h = 64 feet
Step-by-step explanation:
If you graph the function you see that 64 feet is the maximum of the parabola so this is the max height that the projectile reaches.
Answer:
A
Step-by-step explanation:
So we have the equation:

First, let's subtract 16 from both sides:

Now, let's divide both sides by 3:

Remember that with fractional exponents, we can move the denominator into the root position. Therefore:
![(\sqrt[3]{x-4})^4=16](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx-4%7D%29%5E4%3D16)
Let's take the fourth root of both sides. Since we're taking an even root, make sure to have the plus-minus symbol!
![\sqrt[3]{x-4} =\pm 2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-4%7D%20%3D%5Cpm%202)
Cube both sides. Since we're cubing, the plus-minus stays.

Add 4 to both sides.

So, our answer is A.
And we're done!
