Answer:
2 : 3
Step-by-step explanation:
A disc has a diameter of 21 cm while a mini disc has a diameter of 14cm. Write the ratio of the mini disc diameter to the disc diameter.
Answer: Let the diameter of the mini disc be 
while the diameter of the disc be 
. To get the ratio of the mini disc diameter to the disc diameter, we just simply have to divide the diameter of the mini disc by the diameter of the disc and then represent the fraction in ratio form. The ratio of the disc diameters is given by:
Ratio of the mini disc diameter to the disc diameter = Diameter of mini disc / diameter of disc
Ratio of the mini disc diameter to the disc diameter = 
Ratio of the mini disc diameter to the disc diameter = 2 : 3
Answer:
Step-by-step explanation:
a^2+b^2=c^2
7^2+12^2=c^2
=193^2
find the square root of 193

Answer:
77,700
Step-by-step explanation:
look at 690. since the nine is greater than 5 round to 700
Given:
f(x) = x²
g(x) = 4x²
Therefore
g(x) = 4f(x)
This means that the value of g(x) is 4 times the value of f(x). So the graph og (x) is the graph of f(x) vertically stretched by a factor of 4.
The graph shown below confirms the conclusion.
Answer: C.
The graph of g(x) is the graph of f(x) vertically stretched by a factor of 4.
Answer:
(If you were asking for the answer for question 7)
c. Initially, Cassie has $20 in her account.
Step-by-step explanation:
-20 represents the slope or rate of change of the line and 275 represents the y-intercept or starting point of the line on the y-axis. C is the right answer because initially Cassie had $275 in her account, not $20.
