Answer:
B = 44 degree
Step-by-step explanation:
ABC triangle C = 90 degree
AB is slope
A = 46 degree
C = 10.3ft
B = 180-(90+46) = 44 degree as al angles inside a triangle add up to 180 degree.
a = 9.94659 = 9.9 ft
b = 14.31868 = 14.3 ft
Answer:
A
The leading coefficient is negative.
Step-by-step explanation:
Quadratic equation:
A quadratic equation has the following format:

The leading coefficient is a.
a negative:
The graph of the function is concave down, that is, it displays values that approach negative infinity.
a positive:
The graph of the function is concave up, that is, it displays values that approach up infinity.
In this question:
Displays values that approach negative infinity, so the leading coefficient is negative, and the correct answer is given by option A.
Answer:
Step-by-step explanation:
0 is not an interval, it is just the origin
hard to make an estimate without knowing the limits.
average rate of change will be Δy / Δx or (y - y₀) / (x - x₀)
as (0, 0) is the origin and appears to be on the plot line, the average rate of change will be y/x for any other point on the curve relative to the origin.
EDIT
for interval 0 ≤ x ≤ 8
at x = 8 y appears to be -24
average change is -24 / 8 = -3
4x/5 - y = -2 im pretty sure
Hope this helps !
