Answer: sqrt of 5x+7+ sqrt of 5x-7
Step-by-step explanation:
I dont know if its right. it is seven hundred fifty one
Answer:
1,078
Step-by-step explanation:
I got that answer by multiplying 22 and 49. We know that product means to use the multiplication operation so our problem would look like this:
22 * 49 = 1,078
Interest paid by Linda is equal to $4.272 approximately equal to $4.27.
<u>
Solution:
</u>
Given that
Rate of interest on first $200 = 1.8%
Rate of interest on any amount over $200 = 1.2%
Unpaid balance amount of Linda’s credit card bill = $256
Need to calculate interest paid by her on $256.
Unpaid balance = $256
=$200 + 56
Amount over $200 = 56
Interest paid on first $200 = 1.8% of 200
= 0.018 x 200 = $3.6
Interest paid on amount over $200 that is $56 = 1.2% of 56
= 0.012 x 56 = $0.672
So total interest paid on $256 = 3.6 + 0.672 = $4.272.
Hence interest paid by Linda is equal to $4.272 approximately equal to $4.27.
The quadratic equation for this would be f(x) = 5x^2 - 10x - 120.
In order to find that, we need to start by taking our x intercept values and setting them equal to zero.
x = 6 ----> subtract 6 from both sides
x - 6 = 0
x = -4 ----> add 4 to both sides
x + 4 = 0
Now that we have both of these zero terms, we can multiply them to get a standard form.
f(x) = (x - 6)(x + 4)
And while this will give us the zeros we need, it will no give us the lead coefficient. So we must multiply by the desired lead coefficient.
f(x) = 5(x - 6)(x + 4)
f(x) = 5(x^2 - 6x + 4x - 24)
f(x) = 5(x^2 - 2x - 24)
f(x) = 5x^2 - 10x - 120
