Answer:
126 inches
Step-by-step explanation:
C = 2π·r = π·d = 3.14×40in = 125.6 inches ≈ 126 inches
Answer:
-42
Step-by-step explanation:
-2y = 46
y = 46/ -2
y = -23
Substitute y in y = 4x-11
-23 = 4x -11
-23+11 =4x
-12 = 4x
x = -12/4
x = -3
Now plug in x value in 14x
14(-3) = -42
Answer:
I cant see it
Step-by-step explanation:
The input is the x-coordinate and the output is the y-coordinate. If the input is 4, plug 4 into the x variable to find the output, y.
y=3(4)-5
y=12-5
y=7
The output is 7.
Answer:
22.7604763 degrees
Step-by-step explanation:
Note that the answer is NOT 20 degrees.
She adjusted the ramp to half the original <em>incline</em>
Therefore we have tan 40 = x = 0.839099631.
We want an incline of y degrees where tan y = x/2 = 0.839099631/2 = 0.419549815
Taking the arctan of both sides, we get
y = arctan(0.419549815) = 22.7604763 degrees
