Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (4, 3)
m =
=
= 
First find the length of the line in the middle.
c^2=5^2 + 5^2
c = square root of 50
Then use that to find x.
8^2 - c^2 = x^2
64-50 = x^2
14 = x^2
x = square root of 14
C as the bass is flat and the two sides are straight so no curved edges ruling out all other options and definitely not A as a cross section is 2d
Substitute values and isolate v.
v^2 = u^2 + 2as
v^2 = 8^2 + 2(3)(19)
v^2 = 64 + 114
v^2 = 178
v = √178
v = about 13.3
Since the velocity isn’t exactly 13m/s, it cannot be A, so the correct answer is C.
