Answer:

The value which is possible for the length of the rectangle is:

7 in.

Step-by-step explanation:

We know that in order to form a rectangle the length and width of a rectangle must be in positive dimension.

i.e. l,w>0

where l denotes length and w denotes width of the rectangle.

Also, The perimeter of a rectangle is 16 inches.

Hence, the equation that represents the perimeter of the rectangle is:

2l + 2w = 16.

i.e. on dividing both side of the equation by 2 we obtain:

l+w=8

Now, when l=7 we get w=1

Hence, it could be a possible value.

Also, when l=8 then w=0 which is not possible.

Similarly when l=9, w= -1 which is again not possible.

and when l=10 then w= -2 which is again not a possible dimension.

The answer is:

7 in.

Hello,

Thus l+w=8

if l=7 =>w=1 Possible
if l=8 ==>w=0 Impossible not a rectangle
if l=9==>w=-1 not possible
if l=10 ==>w=-2 not possible.

Answer:

The difference between the size of white blood cells and the size of red blood cells in scientific notation is $5.5 * 10^(-6)$ m.

Step-by-step explanation:

we are given that the size of white blood cells is 0.000012 metres and the size of red blood cells is 0.0000065 metres.

And we have to find the difference between the size of both cells in scientific notation.

SO, Size of White blood cells = 0.000012 m

Size of Red blood cells = 0.0000065 m

Now, Difference between both cell sizes = Size of white blood cells - Size of Red blood cells

= 0.000012 m - 0.0000065 m

= 0.0000055 m

Now, in scientific notation it is represented as = $5.5 * 10^(-6)$ m

Hence, the difference between the size of white blood cells and the size of red blood cells in scientific notation is $5.5 * 10^(-6)$ m.

Korey is planning to open a comic book store. In his first year of operation, Korey expects to average $1,000 of profit each month. He then expects profits to increase by 6% each year for the next 4 years. How much does Korey expect to make in profits in his fifth year of operation?a. $15,149.72
b. $16,058.71
c. $31,120.46
d. $32,987.69

Answers

Answer:

option A

Step-by-step explanation:

given,

Korey expects to average $1,000 of profit each month

first year profit from the comic book store = $1000 × 12

= $12,000

now for next four year profit will increase by 6%

Second year profit: $12,000 × 1.06

Third year profit: $12,000 × 1.06²

Fourth year profit: $12,000 × 1.06³

Fifth year profit: $12,000 × 1.06⁴

=$15,149.72

Profit of Korey expected after fifth year is equal to $15,149.72.

Hence the correct answer is option A

I believe the answer is the first choice. If I’m correct, the numbers outside of the square root are the y intercept, the graph is clearly starting in the negatives, it could be -2 (it being the y intercept). I hope this is right, my apologies if it isn’t.
