What is the measure of arc ADB?
 The measure of the arc for this case is given by the following angle:
 theta = 360-90
 theta = 270 degrees

 What is the length of arc ADB? 

 The arc length is given by:
 s = R * theta
 Substituting values:
 s = 15 * (270 * (pi / 180))
 s = 70.69 m

 What is the area of the shaded region?

 The area of the shaded region is:
 A = (s' / s) * (pi) * (r ^ 2)
 Substituting values:
 A = (270/360) * (3.14) * (15 ^ 2)
 A = 529,875 m ^ 2

Mitchell has $17000 to put towards a car. He wants to invest this money in an account paying 3.3%/a
arsen [322]

Answer:

He can afford the monthly payment of the Ford car since his accumulated interest after 5 years is greater than the amount the Ford will cost

Step-by-step explanation:

For the Ford

There are 60 months in 5 years so the total amount he will be paying is 60 * 299 = $17,940

For the Volkswagen, amount to pay will be 60 * 389 = $23,340

Now to see the payment he can afford, let’s calculate the amount he will have in his savings

We shall use the formula for compound interest here

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

where A is the amount after the

number of years

I is the initial amount = 17,000

r is the rate = 3.3% = 3.3/100 = 0.033

n is the

number of times interest is compounded per year = 12

t = number of years = 5

plugging these values we have

A = 17,000(1 + 0.033/12)^12(5)

A = 17,000( 1.00275)^60

A = $20,045

This shows he can afford the Ford

What is 965,000,000,000,000 in scientific notation?
sveticcg [70]

Answer:

9.65×10¹⁴

Step-by-step explanation:

The 9 of 9.65 has been moved 14 places to the left to get to its position in 965,000,000,000,000. That is, its value has been multiplied by 10¹⁴.

_____

If you were to write 965,000,000,000,000 in expanded form, you would write it as ...

... 9×10¹⁴ +6×10¹³ +5×10¹² +0×10¹¹ +... +0×10⁰ = 9.65×10¹⁴

The first term of this sum is a clue as to how the number is written in scientific notation,
