First, find out how the percentage left from your total.
New Value / Old Value
2.4 / 3.2 = 0.75
This means that 2.4 is 75% of 3.2
To find the decrease we minute the percentage from 100.
100 - 75 = 25
There was a 25% decrease.
Answer:
B
Step-by-step explanation:
The line of reflection of y=x is when the x and y swap places which means that the point of (6,-5) should change to (-5,6)
Hope this helps!
Answer:
Step-by-step explanation:
* Lets explain how to solve the problem
- We can write a sine as a cosine by translate the sine function to the
left by
-
∵ The value of sin(0 + π/2) = 1
∵ cos(0) = 1
∴ sin(0 + π/2) = cos(0)
∴ If sin(x) translated to the left by , then it will be
cos(x)
∴
- <u><em>Vice versa</em></u>
- We can write a cosine as a sine by translate the cosine function to
the right by
-
∵ The value of cos(0 - π/2) = 0
∵ sin(0) = 0
∴ cos(0 - π/2) = sin(0)
∴ If cos(x) translated to the right by , then it will be
sin(x)
∴
