What is the solution to the inequality below x2>25

4vir4ik [10]

Answer:

Ans: (-5, 5)

-5 < x < 5

Step-by-step explanation:

Standard form: f(x) = x^2 - 25 < 0.

First solve x^2 - 25 = 0 --> x = +- 5

Use the algebraic method to solve f(x) < 0. Between the 2 real roots (-5) and (5), f(x) < 0, as opposite in sign to a = 1.

Answer by open interval: (-5, 5)

Answer:

C. 4 weeks

Step-by-step explanation:

We have the formula

$s = 16 \sqrt{7t} + 62$

We are looking for the value of t (number of weeks) when s = 150.

So, we isolate t (well, almost isolate, because it would be hard to read)

$(\frac{s - 62}{16} )^{2} = 7t$

If we replace s by 150 we get:

$7t = (\frac{150 - 62}{16} )^{2} = (\frac{88}{16} )^{2} = (5.5 )^{2} = 30.25$

We have 7t = 30.25. If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.
