Answer:
32/3 pi
Step-by-step explanation:
The volume of the sphere is 4/3 pi r^3. r=2 because it is 1/2 of the diameter. Now just plug it into the equation. 4/3 pi 2^3= 4/3 pi 8= 32/3 pi
Answer:
x= (1/2,0) y= (0,2)
Step-by-step explanation:
To find the y intercept you, you substitute 0 for y and solve. To find the x intercept you substitute 0 for x and solve.
Step-by-step explanation:
TPC and DPC are supplementary angles so
DPC=180-123=57°
Rearrange 3x - 2y = 5 into y = mx + c form:
2y + 5 = 3x
2y = 3x - 5
y = 1.5x - 2.5
The lines must have the same gradient to be parallel and it goes through (-2,2) so you use y - y1 = m(x - x1):
y - 2 = 1.5(x - (-2))
y - 2 = 1.5x + 3
Answer: y = 1.5x + 5
