ANSWER

The correct answer is B

\frac{4b}{ {a}^{2} }


EXPLANATION

The given exponential expression is

4 {a}^{ - 2} b

We can rewrite this as,

4b \times  {a}^{ - 2}

We need to simplify to obtain a positive index, so we apply the following property,


{a}^{ - m}  =  \frac{1}{ {a}^{m} }

This implies that,


4b \times  {a}^{ - 2}  = 4b \times  \frac{1}{ {a}^{2} }

This will finally simplify to,

4b \times  {a}^{ - 2}  =\frac{4b}{ {a}^{2} }


Therefore the correct answer is B

The answer would be D. (3, -4).

Work:
3 = x
-4 = y
3 • 5 = 15
-4 • 2 = -8
15 + -8 = 7

To check: y = x - 7
-4 = 3 - 7
3 - 7 = -4

Find the missing term or terms in each arithmetic sequence.
bezimeni [28]

Answer:

I believe the terms would be 31, 35, 39.

Step-by-step explanation:

We know this because 43-27 is 16. since there are 3 terms missing, we divide the answer by 4, and you get 4. The number you get there is how many you add to each term to get the missing ones. For example, 27+4=31. The pattern is adding 4 to each term. Hope I helped!

Dan's car depreciates at a rate of 15% per year. By what percentage has Dan's car depreciated after 3 years?​
Pavlova-9 [17]

The percentage of deprecation of the car in the third year is 38.59%.

<h3>What is deprecation?</h3>

Depreciation is the decline in the value of an asset as a result of wear and tear.

Deprecation in year 1 = 15%

Deprecation in year 2 = 15% x (100 - 15%) = 12.75%

Deprecation in year 3 = 15% x (85% - 12.75) = 10.84%

Sum of deprecation = 38.59%
