Answer:
D
Step-by-step explanation:
y-y1=m(x-x1) through (4,4)
x-3y= -18 is perpendicular : m1*m2=-1
y=mx+c
-3y=-18-x
3y= 18+x
y=x/3 + 6
y= 1/3x + 6
m1*m2= -1
m1= -1/m2
m1= -1/1/3
m1= -3
y- 4= -3(x - 4)
y-4= -3x +12
y= -3x +12+4
y= -3x + 16
16.76 rounds off to 17
After the dot if it’s 1-4 then they it would’ve been 15
5-9 is 17
If you meant a thickness of 1/2 inch. . .
Because the inserts are put on all the sides, the dimensions of the usable space are 5 X 5 X 9. This means the diameter of the base is 5. The radius is half the diameter, so we divide 5 by 2 to get the radius. 5/2 = 2.5. Now, we plug in the radius and the height (9) into the formula for the volume of a cylinder, which is


So, D is correct.
It is C
all the other options have positive slopes
Y(0)=0+3=3 (0;3)
y(1)=1+3=4 (1;4)
y(2)=2+3=5 (2;5)
x+3=0
x=-3
x+3=1
x=-2
x+3=2
x=-1
