Answer:
f(x) = 3(0.2)^x
Step-by-step explanation:
The leading coefficient is 3 as x = 0 gives f(x) = 3.
When x = 1, f(x) = 0.6. so try :
0.6 =3(1.2)^1 = 3.6 so it's not the fiirst choice.
0.6 = 3(0.2)^1 = 0.6 so its last choice.
Check when x = -1:
3(0.2)^-1
= 3/ 0.2
= 15
If you want to evaluate what percent of 550 is 4, you can do this in two following steps.<span>
<span>First, you have to write it as a fraction: 4</span>/550.
Second, you have to transform this fraction to
percent: (4/550)*100%.
(4/550)*100% = 0.0072727272727273*100% =
0.727%
<span>The correct result is </span>0.727%.</span>
Hey!
Hope this helps...
~~~~~~~~~~~~~~~~~~~~~~
To solve this we will first find out what f(x) equals at the given point of 4, and than substitute that answer it for g(f(4))...
f(x) = x - 7
f(4) = 4 - 7 = -3
g(f(4)) = (x - 7)^2 > -3^2 = 9
So...
The answer is: g(f(4)) = 9
Answer:
Amount of Discount: 85, Discounted cost of item: 340
Step-by-step explanation:
You Start by dividing the main price of the item by 100
You then multiply your answer from that by however much the discount is.
We divide by 100 because there is 100 percent when you are paying full price, dividing by 100 gives you the amount that is equal to 1 percent of that price
You then multiply the answer from that by 20, this will give you 20% of the full price, this will give you a discount of 85 Dollars.
To find the Discounted price you then subtract 85 from 425 and you will have an answer of 340 dollars. Hope this helps!
