Answer:

Step-by-step explanation:

What is the Radius?

1.5

this is just 1/2. 1/2 of 3 is 1.5 (also you can look up how do you find the radius of a circle with the diameter to be sure, a calculator will come up and you can put in the diameter)

What is the Circumference?

9.4

You can figure out the Circumference by multiplying pi by the diameter. (also you can look up how do you find the circumference of a circle with the diameter to be sure, a calculator will come up and you can put in the diameter)

What is the Area?

7.1

how you find the area with just the diameter is 1 /4πd^2 (also you can look up how do you find the area of a circle with the diameter to be sure, a calculator will come up and you can put in the diameter)

Marcus will receive $14869.38 at the end of the 14 years

Step-by-step explanation:

The rule of the future value of the compound interest is:

$FV=P(1+\frac{r}{n})^{nt}$ , where

1. P is the invested money

2. r is the rate of interest in decimal

3. n is the period of compound interest

4. t is the time

Marcus receives an inheritance of 6,000 he decides to invest the

money in a 14-year certificate of deposit that pays 6.5% interest

compounded monthly

We need to find how much money Marcus will receive at the end of

the 14 years

∵ P = $6000

∵ r = 6.5% = 6.5/100 = 0.065

∵ n = 12 ⇒ compounded monthly

∵ t = 14

Substitute these values in the rule above

∴ $FV=6000(1+\frac{0.065}{12})^{(12)(14)}$

∴ FV = $14869.38

Marcus will receive $14869.38 at the end of the 14 years

Solve 14(0.89)x+4.5 =162

dedylja [7]

So the first thing to do is to simplify both sides of this equation:
12.46x+4.5=162
Next we shall subtract 4.5 from both sides so:
12.46x+4.5−4.5=162−4.512.46x=157.5
Now that we are done with all those steps now here is the final steps so now we shall divide both sides by 12.46:
12.46x/12.46 = 157.5/12.46
Ok so your final answer shall be:
x=12.640449
I hope this helps you greatly!

I need help as soon as possible

mote1985 [20]

The sin ratio is the side opposite the reference angle over the hypotenuse. If Z is our reference angle, then the side opposite it has a length of 32. The hypotenuse has a length of 40. Therefore, the sin of Z = 32/40. We will reduce that to sin Z = 4/5. First choice above.

The daily advertising revenue (in dollars) for a local newspaper is given by the function R(t) = -18t2 + 720t – 103, where t is

erastovalidia [21]

Answer:

6647

Step-by-step explanation:

The computation of the advertising revenue for 15 years is shown below:

Given that

r(t) = -18t^2 + 720t - 103

where

t = number of years = 15

now put the value of t in the above equation

= -18(15)^2 + 720(15) - 103

= -4050 + 10,800 - 103

= 6647
