Which expression uses the associative property to make it easier to evaluate? (50points)

Naily [24]

The correct answer is option 4: $(8.\frac{1}{4}).\frac{3}{5}$

Step-by-step explanation:

Given expression is:

$8.(\frac{1}{4}.\frac{3}{5})$

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.

Let a,b and c be the three terms

then

$a.(b.c) = (a.b).c$

So applying the associative property on given expression

$8.(\frac{1}{4}.\frac{3}{5}) = (8.\frac{1}{4}).\frac{3}{5}$

Hence,

The correct answer is option 4: $(8.\frac{1}{4}).\frac{3}{5}$

suppose you deposit $1000 in a savings account that pays 4.8% interest compounded monthly. Write an exponential function to mode

zubka84 [21]

Answer:

The exponential function is $A(t) = 1000(1.004)^{12t}$ .

You will have $1,100.55 in the account after 2 years.

Step-by-step explanation:

Compound interest:

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 year and t is the time in years for which the money is invested or borrowed.

Deposit $1000 in a savings account that pays 4.8% interest compounded monthly.

This means that $P = 1000, r = 0.048, n = 12$ . So

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

$A(t) = 1000(1 + \frac{0.048}{12})^{12t}$

$A(t) = 1000(1 + 0.004)^{12t}$

$A(t) = 1000(1.004)^{12t}$

This is the exponential function

How much will you have in your account after 2 years?

This is A(2). So

$A(2) = 1000(1.004)^{24} = 1100.55$

You will have $1,100.55 in the account after 2 years.

Find the radius and circumference of a CD with a diameter of 4.75 inches. SOMEONE PLEASE HELP ME!!!!!

igomit [66]

The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7

Solve H= -b divided by 2a for b

nata0808 [166]

Answer:

b=-2aH

Step-by-step explanation:

H=-b/2a

Apply cross multiplication

H×2a=-b

2aH=-b

In the question you are to find positive b not negative b so you have to take negative b to the left hand side of the equation to become positive b and take 2aH to the right hand side to become -2aH

therefore b=-2aH
