CAN SOMEONE HELP ME ASAP

BARSIC [14]

Answer:

3 minutes

Step-by-step explanation:

To calculate this, you have to multiply 4.5 minutes by 8. This will give you the amount of pages that Wafa will print.

4.5 x 8 = 36 pages

Now that you have the amount of pages, you should divide it by the speed of the Sure-Fire printer. 12 ppm means that 12 pages can be printed in 1 minute.

36/12 = 3

Therefore, it would take 3 minutes if Wafa were to use her brother's Sure-Fire printer.

20. BUSINESS The function f(x) = 1000-0.01x² models the manufacturing cost per item when x items are produced,

tamaranim1 [39]

Answer:

Profit is calculated by subtracting the total cost from the total revenue as expressed in the equation given above as,

P(x) = R(x) - C(x)

If we are to substitute the given expression for each of the terms, we have,

P(x) = x(S(x)) - C(x)

Substituting,

P(x) = x(30 - 0.01x) - (0.15x³ + 0.01x² + 2x + 120)

Simplifying,

P(x) = 30x - 0.01x² - 0.15x³ - 0.01x² - 2x - 120

Combining like terms,

P(x) = -0.15x³ - 0.02x² + 28x - 120

The answer to this item is the second among the choice, number 2.

Calvin deposits $400 in a savings account that accrues 5% interest compounded monthly. after c years, calvin has $658.80. makayl

pochemuha

Answer:

The approximate difference in time is 2 years.

Step-by-step explanation:

The equation for Calvin's account is

$658.80=400(1+\frac{0.05}{12})^{12c}$

To solve for c, we first divide both sides by 400. This gives us:

$1.647=(1+\frac{0.05}{12})^{12c}$

Using logarithms to solve this, we have

$\log_{1+\frac{0.05}{12}}1.647=12c\\\\119.9986131=12c$

Dividing both sides by 12, we get c = 9.9998 or around 10 years.

The equation for Makayla's account is

$613.04=300(1+\frac{0.06}{4})^{4m}$

Dividing both sides by 300, we get

$2.043466667=(1+\frac{0.06}{4})^{4m}$

Using logarithms to solve this, we have

$\log_{1+\frac{0.06}{4}}2.043466667=4m\\\\4m=47.9961799$

Dividing both sides by 4, we get

m = 11.9999 or about 12.

This means Makayla had her money in the account 12-10 = 2 years longer than Calvin.
