4x^2 - 36 = 0

4x^2 = 36

x^2 = 36/4

x^2 = 9

sqrt{x^2} = sqrt{9}

x = - 3 and x = 3

Answer:

Step-by-step explanation:

You need to use Pythagorean's Theorem to find the height of the pole. Namely,

$pole^2+15^2=113^2$ and

$pole^2=113^2-15^2$ and

$pole^2=12769-225$ and

$pole^2=12544$ so

pole = 112 cm

Answer:

Step-by-step explanation:

30t - 5t² = 10

5t² - 30t + 10 = 0

t = [30 ± √(30² - 4 ⋅ 5 ⋅ 10)] / [2 ⋅ 5]

= [30 ± √700] / 10

= [30 ± 10√7] / 10

= 3 ± √7

≈ 0.35 seconds and 5.65 seconds
