Answer:

The value is $v(3) = 29.4 \ m/s$

Step-by-step explanation:

From the question we are told that

$s(t) = -4.9t^2 + 500$

And

$\lim_{t \to a} \frac{s(a) - s(t)}{a-t}$

Generally s(t) at t = a is mathematically evaluated as

$s(a) = -4.9a^2+ 500$

So

$s(a) - s(t) = -4.9a^2 + 500 - ( -4.9t^2+500)$

$s(a) - s(t) = -4.9a^2 + 500 +4.9t^2-500)$

$s(a) - s(t) = 4.9(t^2 - a^2)$

Thus the velocity is represented as

$v(t) =\lim_{t \to a} \frac{s(a) - s(t)}{a-t} \equiv \lim_{t \to a} \frac{4.9(t^2 - a^2 )}{ a-t}$

=> $v(t) = \lim_{t \to a} - 4.9(a + t )$

=> $v(t) = -4.9 (a + a )$

=> $v(t) = -9.8a$

Now at t = 3

=> $v(3) = -9.8 (3)$

=> $v(3) = 29.4 \ m/s$

What value is added to both sides of the equation x^2 − 6x = 10 in order to solve by completing the square? (1 point)

snow_lady [41]

Answer:

9

Step-by-step explanation:

use half the x coefficent and square it

x^2 − 6x + (-3)^2 = 10 + (-3)^2

x^2 - 6x + 9 = 10 + 9

(x - 3)^2 = 19
