Choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8

Maru [420]

Answer:

$f(x)=8x^2+73x-70$

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

$f(x)=a(x-(-10))(x-\frac{7}{8})$

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

$f(x)=8(x-(-10))(x-\frac{7}{8})$

now, we can simplify it

$f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)$

so, we get

$f(x)=8x^2+73x-70$

Can somebody please help me with this question?

Minchanka [31]

In the problem, t is said to be the time in seconds and h is the height. The only value we can plug into the right side of the equation is t, time, and we are solving for h, height. Therefore, h(2) is the height of the ball after 2 seconds.

The correct answer is the red square, the height of the ball after 2 seconds.

Hope this helps!! :)

If the area of a circle is 121pie square units, what is the diameter

velikii [3]

Since you are given the area, we can solve for radius with this equation:
$A_c = \pi r^2$
$r = \sqrt{ \frac{A_c}{ \pi } } = \sqrt{ \frac{121 \pi }{ \pi } } = \sqrt{121} = 11$

The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is 22 units²
