Can you please explain the answer to me

Leviafan [203]

Answer:

$b=\sqrt{7}$

Step-by-step explanation:

When we solve for this we should always remember this formula $a^2+b^2=c^2$ and since we already know a and c we can plug that in to find out what b could be but we won't actually solve it.

$a^2+b^2=c^2\\3^2+b^2=4^2\\9+b^2=16\\b^2=7\\\sqrt{b^2}=\sqrt{7}\\b=\sqrt{7}$

So b would equal whatever the square root of 7 is.

Which is the BEST estimate of the average rate of change for the function given in the table, over the interval 2 ≤ x ≤ 4?

ladessa [460]

Answer:

Step-by-step explanation:

Use the slope formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Picking x = 2 and x = 4 as my two points (since the interval is 2 ≤ x ≤ 4), we get:

$m = \frac{15-3}{4-2} = \frac{12}{2} = 6$

So, the BEST estimate of the average rate of change for the function given in the table is 6.
