Answer:
5.5%
Step-by-step explanation:
Given data
Simple interest = $137.50
Principal= $500
time = 5 years
We want to find the rate R
Simple interest= PRT/100
137.50 = 500*R*5/100
137.50=2500R/100
cross multiply
137.5*100= 2500R
13750= 2500R
divide both sides by 2500
R= 13750/2500
R=5.5%
Hence the rate is 5.5%
Answer:
x = 2 / 3 or x = 2
Step-by-step explanation:
3x² = -4 + 8x
3x² - 8x + 4 = 0
3x² - 6x - 2x + 4 = 0
3x ( x - 2 ) -2 ( x - 2 ) = 0
( 3x - 2 ) ( x - 2 ) = 0
Therefore,
3x - 2 = 0 or x - 2 = 0
3x = 2 x = 2
x = 2/3
Hope this helps you :-)
Answer:
B. f(x) = 1 - x²
Step-by-step explanation:
Since we are dealing with only vertical movement, all we change is the constant. Since the red graph is up one from the reflected parent graph, we know our graph is f(x) = -x² + 1 or f(x) = 1 - x².
