Answer:
9.230095943 or 9.2
Step-by-step explanation:
Trigonometry: sine, cosine, tang: Sohcahtoa
O: opposite(side from angle)
H: hypotenuse(side opposite from 90*)
A: Adgacent(side from angle)
Use scientific calculator: tang(40*) x 11 = 9.230095943
Answer:
5π or 15.71 inches
Step-by-step explanation:
Length of an arc = 
× 2πr
Where x is the angle and r is the radius
so 
× 2 × π × 10
0.25 × 2 × π × 10
Arc length = 5π inches (answer in terms of π)
= 15.71 inches (answer in two decimal places)
Answer:
A
Step-by-step explanation:
Add 3x^2 and 5x^2 now it = 8x^2
Add -8x and -4x = -12x
look at your answer choices the only one that has 8x^2-12x is A
Answer:
D) 1/25
Step-by-step explanation:
The formula for slope is
m = (the change in y)/(the change in x)
Y is always the vertical change, x is always the horizontal change.
For this problem, the road rises 4 feet (y) for every 100 feet of length (x), so the slope is..
m = 4/100
m = 1/25
