Answer:
11/7 feet
Step-by-step explanation:
Perimeter of a circle = pi
Semicircle would be 1/2 of pi
1/2 × 22/7 × 1
You must divide by one to get the value of 1/2
11/7 is the answer
So the formula for slope is (y2 - y1)/(x2-x1), so here that would be
(-5-(-20))/(-18-(-18)) which would simplify to
(-4 +20)/(-18+18) = 16/0 and you cannot divide by 0 so the slope would be undefined
Answer:
63.57817848
Step-by-step explanation:
all will be in degrees:
cos 40 sinx - sin 40 cos x = sin(x - 40) by the formula sin(A − B) = sinA cosB − cosA sinB
sin(x - 40) = 2/5
x - 40 = arcsin(2/5)
x - 40 = 23.57817848
x = 63.57817848 degrees
Step-by-step explanation:
part A
all listed features (A - F) are correct and to be selected.
part B
the average rate of change is
(f(x2) - f(x1)) / (x2 - x1)
so,
(f(0) - f(-2)) / (0 - -2) = (2 - 0) / (0 + 2) = 2/2 = 1
