-5x - 25 = 78
-5x = 78 + 25
-5x = 103
x = 103/-5
x = -20.6
Compare her solution with that above.
number 3 and 4 you should answer on that axis
number 5 = 12
6.4 + 10 = 14
7.9+2 = 11
8.13 - 5 = 8
9.16 - 2 = 14
10.15 + 7 = 22
Answer:
The effect of translating points is just changing the points, nothing else. Dilations change size, reflections reflect the image across the x, y, or y=x axis, etc..
Step-by-step explanation:
Answer:
a. 9,416.9 mm²
Step-by-step explanation:
Given:
Circumference of a sphere = 172 mm
Required:
Surface area of the sphere rounded to nearest tenth
Solution:
First, we need to determine the radius of the sphere since we know the circumference.
Circumference = 2πr
Plug in the value of the circumference
172 = 2*π*r
Divide both sides by 2π
172/2π = r
86/π = r
r ≈ 86/π
Next, find the surface area of the sphere
Surface area = 4πr²
plug in the value of r
Surface area = 4*π*(86/π)²
= 4*π*86²/π²
= 4*7,396/π
= 9,416.87967
≈ 9,416.9 mm² (nearest tenth)
y-2=5(x-(-3))
or
y-2=5(x+3)
(they represent the same thing)
