nw we have
1/2*(15)+11
multiply 1/2 and 15 and get 15/2=7 and 1/2
then add 11
7+11=18
18 and 1/2 is answer or 37/2 or 18.5

Maureen earned some money doing odd jobs last summer and put it in a savings account that earns 9% interest compounded quarterly

ivolga24 [154]

Answer:

Maureen earned $123.19 doing odd jobs

Step-by-step explanation:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per unit year and t is the time in years for which the money is invested or borrowed.

In this question:

Compounded quarterly means that $n = 4$

10 years, so $t = 10$

9% interest, so $r = 0.09$

There is $300.00 in the account, which means that $A = 300$

How much did Maureen earn doing odd jobs?

This is P.

$A(t) = P(1 + \frac{r}{n})^{nt}$

$300 = P(1 + \frac{0.09}{4})^{4*10}$

$(1.0225)^{40}P = 300$

$P = \frac{300}{(1.0225)^{40}}$

$P = 123.19$

Maureen earned $123.19 doing odd jobs

Consider f(x) = bWhich statement(s) are true for 0 < b < 1? Check all that apply.

Ira Lisetskai [31]

Answer:

The domain is all real numbers.

The function is always decreasing

Step-by-step explanation:

Assuming the given function is

$f(x) = {b}^{x}$

for

$0 \: < \: b \: < \: 1$

Then f(x) is an exponential decay function.

This means that, the domain will be all real numbers.

The range will be y<0

The y-intercept is (0,-1)

There is no x-intercept.

The graph is a decreasing function.

Consider the leading term of the polynomial function. What is the end behavior of the graph? Describe the end behavior and provi

Nookie1986 [14]

The leading term is -3x^5. The end behavior of any function is the behavior that the highest powered term has as x approaches ±oo.

In this case because the highest order term is -3x^5, as x approaches -oo, y approaches +oo. And as x approaches +oo, y approaches -oo.

1000:300:750 simplified

atroni [7]

Answer: 40:12:30

Step-by-step explanation:

To simplify this, look for a common divisible number, which is 25

Then divide all through by 25

1000/25:300/25:750/25

=40:12:30

I hope this helps
