Answer:
r=94.2
Step-by-step explanation:
C=pi`d
C=3.14 multiplied by 30
C equals about 94.2
Answer:
sin(A-B) = 24/25
Step-by-step explanation:
The trig identity for the differnce of angles tells you ...
sin(A -B) = sin(A)cos(B) -sin(B)cos(A)
We are given that sin(A) = 4/5 in quadrant II, so cos(A) = -√(1-(4/5)^2) = -3/5.
And we are given that cos(B) = 3/5 in quadrant I, so sin(B) = 4/5.
Then ...
sin(A-B) = (4/5)(3/5) -(4/5)(-3/5) = 12/25 + 12/25 = 24/25
The desired sine is 24/25.
We have no idea how 'x' responds to changes in 'y'.
We don't even know their units, to make a guess with.
-- If 'x' and 'y' are the ages of two people, then when y = 30, 'x' will be 23.
-- If they are the frequency and wavelength of a wave on the lake,
then when y = 30, 'x' will be 2 .
-- If 'x' is the weight of a rock in your front yard and 'y' is the number of pages
in today's newspaper, then 'y' has no effect on 'x'. No matter what happens
to 'y' . . . 'x' will always be 5 .
With the information given in the question, we just don't know.
We need either an equation, or else one more example.
Answer:
x < -15
Step-by-step explanation:
-1x + 5 < 20
- 5 - 5
-1x < 15
/-1 /-1
x < -15
