For the answer to the question above,
since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.
<span>That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value we multiply by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked. </span>
<span>You can also check this by plugging in values: </span>
<span>Assume 10 doors are knocked: </span>
<span>E(10) = 20(10)-50 = 200-50 = 150 </span>
<span>Assume 11 doors (1 more door) is knocked: </span>
<span>E(11) = 20(11)-50 = 220-50 = 170 </span>
<span>The increase from 1 door is $20.</span>
Answer:
y = x
Step-by-step explanation:
The C's are both placed at 5
Since we know that the two functions are equal, f (x) = g
(x), therefore when we equate the two equations the result should be similar to
3x = x – 4:
A. f(x) = 3x, g(x) = x – 4
Equating the two functions:
3x = x – 4 (correct)
So we now got our answer (A)
whatttttttt? i have no idea what that is
Answer:
Chan is not correct.
The correct equivalent quarterly interest rate is 1.3108% per quarter.
Step-by-step explanation:
Given that Chan deposited money into his retirement account.
The interest was 7% compounded annually.
Let P be the amount invested and F the final amount got after 1 year
If compounded annually,
F = P(1+0.07) = 1.07P
If compounded quarterly, no of quarters = 4
F = ![P(1+\frac{7}{100} )^4](https://tex.z-dn.net/?f=P%281%2B%5Cfrac%7B7%7D%7B100%7D%20%29%5E4)
= 1.3108P
Hence equivalent interest rate = 1.3108% and not 2%
