Answer:

Option 4

Step-by-step explanation:

2(a+6)

Substitute a=2:

2(2+6)=2(8)=16

-------------------------------

Check first option:

4a+8

Substitute a=2:

4(2)+8=8+8=16

Since 16 is not greater than 16, the first option is incorrect.

-------------------------------------------------------------------------------------

Check second option:

2a+a^2

Substitute a=2:

2(2)+2^{2} =4+4=8

Since 8 is not greater than 16, the second option is incorrect.

-------------------------------------------------------------------------------------

Check third option:

2a+12

Substitute a=2:

2(2)+12=4+12=16

Since 16 is not greater than 16, the third option is incorrect.

-------------------------------------------------------------------------------------

Check fourth option:

a^4+2

Substitute a=2:

2^4+2=16+2=18

Since 18 is greater than 16, the fourth option is correct.

When NB = 12 ft, find the area of the region that is NOT shaded. Round to the nearest tenth.
Alborosie
If this item has the same picture on the same question posted before, the following will be the data.

Given: NB = 12 ft, Angle-120°<span>
Asked: area of the region that is not shaded.
Substitute the given values in the equation in finding the area of a circle.
</span>A = πr² 
<span>A = ⅔π(12 ft)² </span>
<span>A = 96π ft² 
(Since </span>120° is 1/3 of the circle. it is then understood that the unshaded parts must be 2/3 of the circle.)
Since you already have the area, find the area of the triangle to add it to the area of the circle to find the area of the unshaded part. By using a handy trigonometry, you can tell that their will be 2 triangles of 12 ft (if you are going to divide 120° angle). From this, you'll see that there will be one of the smaller triangles having a <span> the height of 6 ft and the base is 6√3 ft. Substitute the values.</span>
A = ½bh 
<span>A = ½(6 ft)(6√3 ft) * 2 </span>
<span>A = 36√3 ft² 
</span>
Add them up and you will have the exact answer  96π + 36√3 ft², when rounded to the nearest tenth, you will have <span> 364 ft². </span>

If you invest $5,000 at 1.8 percent for 5 years, compounded quarterly, what is the amount in the
Drupady [299]

Answer: C. $5,470

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1 + r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = $5000

r = 1.8% = 1.8/100 = 0.018

n = 4 because it was compounded 3 times in a year(12/4 = 3 times)

t = 5 years

Therefore,

A = 5000(1 + 0.018/4)^4 × 5

A = 5000(1 + 0.0045)^20

A = 5000(1.0045)^20

A = $5470 to the nearest whole number
