Answer:
Step-by-step explanation:
Let the number of cups of onions Katrina still needs to chop = x
She has already chopped the onions = 
cups ≈ 
cups
So total amount of chopped onions = 
cups
Since, onion soup recipe calls for the chopped onions = 
cups ≈ 
cups
Therefore, equation which shows the number of cups of onions to be chopped more will be,
We further solve this equation for the value of x,
x = 
x = 
= 
cups
≈ 
cups
You have the formula. Put in the numbers and solve for r.
The interest earned in 4 years on 5000 is (6500 -5000) = 1500.
.. I = Prt
.. 1500 = 5000*r*4
.. 1500/20000 = r = .075 = 7.5% . . . . . . matches selection B
Answer:
Step-by-step explanation:
x+10=0
x=-10
so vertex is (-10,-105)
<span>D. y = 20(0.75)^x,
for function to be decreasing value under exponent should be less than 1,
y(int) can be found when x=0
</span>y = 20(0.75)^0=20*1=20
