4 0

Answer:

It can be 5 or 3

Step-by-step explanation:

let x = that number

x * (x - 8) = -15

xx - 8x + 15 = 0

xx - 3x - 5x + 15 = 0

x(x - 3) - 5(x - 3) = 0

(x - 5)(x - 3) = 0

then x = 5 or x = 3

Answer:

Average velocity is 32 miles/hr.

Step-by-step explanation:

Given that a particle moves on a line away from its initial position so that after t hours it is $s=6t^2+2t$ miles from its initial position.

We have to find the average velocity of the particle over the interval [1, 4].

As, average velocity is the change is position over the change in time.

$s(4)=6(4)^2+2(4)=104$

$s(1)=6(1)^2+2(1)=8$

∴ $\text{Average Velocity=}\frac{s(4)-s(1)}{4-1}$

= $\frac{104-8}{3}=\frac{96}{3}=32miles/hr$

Hence, average velocity is 32 miles/hr.
