Answer:
Finding the Average Rate of Change of a Function
To find the average rate of change, we divide the change in the output value by the change in the input value. The Greek letterΔ (delta) signifies the change in a quantity; we read the ratio as “delta-y over delta-x” or “the change iny divided by the change inx.
Answer:
Step-by-step explanation:666 niger
Width: W
length: L = 5W
Use the Pyth. Theorem to find the length of the diagonal:
|D| = sqrt(W^2 + [5W]^2) = sqrt(W^2 + 25W^2) = sqrt(26W^2), or
Wsqrt(26) (ans.)
Hey there!
Let's start by finding what 1% of 210 is.
This can be done by dividing 210 by 100, since 1% is the same as 1/100 of something.
210 ÷ 100 = 2.1
To find 36%, we can multiply 2.1 by 36.
2.1 x 36 = 75.6
So, 36% of 201 is 75.6.
Hope this helps!
Answer:
Her son is 10 years old.
Step-by-step explanation:
Let son be x
Ellie is 4x
In 5 years time: Her son = x + 5
Ellie = 4x + 5
Given that she will then be 3 times as old as her son: 4x + 5 = 3(x + 5)
Solve x: 4x + 5 = 3(x + 5) ,4x + 5 = 3x + 15
x = 10
