Answer:
choice 4) 33.5 in³
Step-by-step explanation:
r = 4/2
V = 4/3πr³ = 4/3(3.14)(2³) = 33.5 in²
y = 12 is a line in which every point has a y-coordinate of 12 no matter what the x-coordinate is. That means that y = 12 is a horizontal line. The equation of line y = 12 can be written as y = 0x + 12 clearly showing m = 0 (slope is zero) and the y-intercept is 12. A line parallel to line y = 12 has the same slope, so its slope is also zero.
A line perpendicular to y = 12 is a vertical line. For a vertical line, the slope is undefined because it involves division by zero which is undefined in math.
5x + 75 = 120
5x = 45
x = 9
The quadriatic portion of a quadriatic equation is actually the term x^2. On the other hand, the constant in a quadriatic equation are a, b, c, or whatever letter except for x, which is a variable.
Answer:
a. is equal to -21
b. is equal to -1
c. is equal to 31
Step-by-step explanation:
a. 2(-2)²-5
-4²-5
-16-5
= -21
b.2(1)²-5
2²-5
4-5
= -1
c.2(3)²-5
6²-5
36-5
= 31
