Answer:
1/16
Step-by-step explanation:
4^-2 is the same as 1/4^2
and then calculate 4^2 to get 16, making it 1/16.
Answer:
Step-by-step explanation:
Find the Supplement to 101
Supplementary angles = 180 degrees
180 = 101 + unknown Subtract 101 from 180
unknown = 79
Because the upper triangle is marked as having 2 equal sides, the left angle is also 79 degrees,
Now the vertex angle is 79 + 79 + y = 180 All triangles have 180 degrees
158 + y = 180 Subtract 158 from both sides
y = 180 - 158
y = 22
y is vertically opposite the vertex angle of the lower triangle. Both the sides are marked as equal, so the angles opposite them are equal as well.
x + x + 22 = 180 Combine
2x + 22 = 180 Subtract 22 from both sides.
2x = 180 - 22
2x = 158 Divide by 2
x = 158/2
x = 79
Assuming we’re talking about a cylinder, whose volume formula is V = pi r^2 h…
It will have a greater effect to change a variable’s value that has a greater power on it.
Changing h from 1 to 2 doubles the volume.
Changing r from 1 to 4 quadruples the volume, because 1^2 = 1 and 2^2 = 4. The effect of the change on r is amplified by the power.
Xintercept is where the line crosses the x axis or where y=0
yintercept is where the line crosses the y axis or where x=0
aka
finding the finding the x intercept is finding the x value when y=0
finding the finding the y intercept is finding the y value when x=0
y=-1/2x-5
xint
y=0
0=-1/2x-5
5=-1/2x
-10=x
(-10,0) is x intercpet
yint
set x=0
y=-1/2(0)=5
y=-5
(0,-5) is yint
xint: x=-10 or at point (-10,0)
yint: y=-5, or at point (0,-5)
