to find the inverse exchange the x and y and then solve for y
y =2x^2
x =2y^2
divide by 2
x/2 = y^2
take the square root of each side
sqrt(x/2) =y
the inverse of y =2x^2 is sqrt(x/2)
A, C, and E will be your correct answers! When 16:28 is simplified we get 4:7. When we simplify 20:35 we get 4:7. therefore, A, C, and E will be correct!
Answer:
$30.88
Step-by-step explanation:
The account value is given by ...
A = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual interest rate, t is the number of years, n is the number of times interest is compounded per year.
The amount of interest earned is the account value less the initial investment:
I = A - P = P(1 +r/n)^(nt) -P = P((1 +r/n)^(nt) -1)
Filling in the given values, we get ...
I = 500((1 +.03/12)^(12·2) -1) = 500(1.0025^24 -1) ≈ $30.88
The amount of interest earned is $30.88.
We have an equation: 13/?= 26/100
Cross multiply:
26*?= 13*100
⇒ ?= 13*100/26= 50
13 is 26% of 50~
