The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the perimeter of the rectangle.

Answers

Answer 1

Answer:

5 ft and 11 ft

Step-by-step explanation:

l= 2w+1

A=lw= 55

w(2w+1)=55

2w²+w-55=0

integer solution of quadratic equation is:

w=5 ft

l= 2*5+1=11 ft

Answer 2

Answer:

32 feet

Step-by-step explanation:

Start by creating your 2 equations

l = 2w + 1

l * w = 55

Plug in l, the isolated variable

(1 + 2w)w = 55

w + 2w² = 55

2w² + w -55 = 0

( − 5 ) ( 2 + 1 1 ) = 0

w= 5

w= -11/2 <- the width can't be negative so this one is out

Plug width into the area formula to find length

l * 5 = 55

l = 11

Find the Perimeter

2(11) + 2(5)

22 + 10 = 32

A line is reflected, what line is the results?

Answers

Answer:

A I think

Step-by-step explanation:

I dont really get the question so im not sure

Answer:

C.

Step-by-step explanation:

The question states that a LINE is reflected, just with this information we know that A. is incorrect because it is curved.

At first, when looking at B., it seems as though it could work, until you notice that it starts somewhere, but doesn't end, thus it is not a LINE. So, we can count B as incorrect as well.

When looking at C, it it a straight line, and has a beginning and and end, which means that so far, it is the most likely the line.

Then, we look at D. When looking at D, we can tell that it is a straight line, however, it has no beginning and no end, thus it can't be the answer.

Now, we know that C is the only possible answer for this question.

There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.

From Year 1 to Year 4, the average rate of change of the population was about 62.4 bass per year.

From Year 5 to Year 8, the average rate of change of the population was about 67.6 bass per year.

The rate of change increased by about _____ bass per a year.

Answers

Answer:

years 1–4: 62.4 bass per year

years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

 p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

 (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

___

For years 5–8, the rate of change is similarly computed:

 (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.
