Step-by-step explanation:
Root:(1/2, 0)
Domain: x∈R
Range: y∈R
Vertical intercept: (0, 1)
So the amount needed=area of circle times height
area formula=pi times radius^2
height=3/4
so
pi=aprox 3.14
radius=7
3.14 times 7^2
3.14 times 49
153.86
times 3/4
115.395 in^3
answer is 115.4 cubic inches
Since it is perpendicular to y=3x-1, the slope must be a negative reciprocal.
there the slope of the perpendicular line is
So now we have,
To find b, we use the point that the line passes through and substitute it to the y and x values.
which would give us b=5/3
Therefore, the equation of the line is
Answer:
x > -3
Step-by-step explanation:
-2x < 9 - 3
-2x < 6
-x < 3
x > -3
