Answer:
D
Step-by-step explanation:
The quadratic formula:
where a is the coefficient of , b being the coefficient of and c being the constant.
Plug in the values:
Since
The answer is:
The slope of the line that passes through (1, -3) and (0, 2) is: B. m = -5.
<h3>What is the Slope of a Line?</h3>
Slope (m) = rise / run = change in y / change in x.
Given the points, (1, -3) and (0, 2):
Slope (m) = (-3 - 2)/(1 - 0)
Slope (m) = -5/1
Slope (m) = -5
Therefore, the slope of the line is: B. m = -5.

The height of the taller building is 18.6 meters
<h3>How to find the side of a right triangle?</h3>
A right triangle has one of its angles as 90 degrees. The side of a right angle triangle can be found using trigonometric ratios.
Therefore, the height of the taller building is the sum of the height of the smaller building and upper part of the taller building.
tan 53 = opposite / adjacent
tan 53 = x / 10
cross multiply
x = 10 tan 53
x = 10 × 1.32704482162
x = 13.2704482162
x = 13.3 m
tan 28 = y / 10
y = 10 tan 28
y = 5.31709431661
y = 5.3
Therefore, the height of the taller building is 13.3 + 5.3 = 18.6 meters.
