Answer:
x ^2+
y^
2
=
25
Step-by-step explanation:
Square both sides:
r
^2
=
5^
2
Substitute x
^2
+
y^
2 for r
^2
:
x
^2+
y
^2
=
5
^2
Insert the center -0 into the x and y terms:
(
x
−
0
)^
2
+
(
y
−
0
)
^2
=
5
^2
This is the standard form for a circle whose center is (
0,
0
) and the radius is 5.
Answer:
0.7% off
Step-by-step explanation:
9.67 × y = 9.6 × 100
9.67y = 960
9.67y ÷ 9.67 = 960 ÷ 9.67
y = 99.2
100% - 99.2% = 0.8%
One Answer: Choice C) 0 < x < 1
==================================================
Explanation:
Let's go through the answer choices one at a time.
- Choice A represents an increasing interval since the graph goes uphill as we move from left to right. The line through the points (-2, f(-2)) and (-1.5, f(-1.5)) has a positive slope. We can rule out choice A.
- Choice B is a similar story to choice A. The graph goes uphill when we move from x = -1 to x = 0, so the graph is increasing on the interval -1 < x < 0. We can rule out choice B.
- In contrast, choice C is a decreasing interval. Going from x = 0 to x = 1 has us move downhill. Choice C is the only answer.
- Choice D is false because choice C was shown to be true.
