Answer:
Step-by-step explanation:
To find the length of the pole, use Pythagorean theorem,
4.6m = 4.6*100 = 460 cm
hypotenuse² = base² + altitude²
altitude² = hypotenuse² - base²
=460² - 280²
= 211600 - 78400
= 133200
altitude = √133200 = 364.97 cm
Length of the pole = 364.97 cm
b) Length of stair² = 95² + 364*94²
= 9025 + 133200
= 142225
Length of stair= √14225 = 377.13
Length of stair = 377.13 cm

The answer is c. Really not much to explain besides it’s c
Answer:
p = 3
Step-by-step explanation:
Given that x = - 4 is a zero then p(- 4) = 0, that is
p(x) = x² - 2x - (7p + 3), then
(- 4)² - 2(- 4) - 7p - 3 = 0, that is
16 + 8 - 7p - 3 = 0
21 - 7p = 0 ( subtract 21 from both sides )
- 7p = - 21 ( divide both sides by - 7 )
p = 3
