volume of sphere = V=(4/3)(pi)r^3
so V = (4/3) x 3.14 x 20^3 = 33,493.33 cubic cm
11.25
Convert 15% to decimal of 0.15
Then multiply 0.15 by 75 to get 11.25
Answer:
Here you go sorry.
Step-by-step explanation:
Question 1.
y = 4x - 8 has a slope of 4. Since parallel lines have equal slopes, the slope of your new line will also be 4.
Now, you have a point (3,9) and a slope 4. Use the Point-Slope Form for the equation of a line.
y - y1 = m(x - x1)
y - 9 = 4(x - 3)
y - 9 = 4x - 12
y = 4x - 3
Question 2.
Since it is parallel, it must have the same slope.
y = (1/2)x + b
Find b from the given point.
4 = (1/2)(2) + b
b = 3
y = (1/2)x + 3
