It asks you to choose values for w, the width, and evaluate the equation for each. It describes the constraint "the perimeter of 20 units" The perimeter of a rectangle is the length of all the lines of a regtangle.
Or
2L + 2W = 20 reduce this to simplest for by dividing both sides by 2;
L + W = 10, so the length plus the width is 10. Rearrange it to be W = 10 - L. Values of W can range from 1 to 9. Now sove for a few points in the function.
f(W) = 10W - W^2
3; 10(3) - 3^2 = 30 - 9 = 21.
If we look at the constraint, L = 10 - W, when the width is 3 the length must be 7. The area of a rectangle is L x W, 3 x 7 = 21. That checks against the function.
Solve for additional points.
4; 10(4) - 4^2 = 40 - 16 = 24.
If W is 4 the L is 6 and 4 x 6 = 24

how do you find the slope of a line
Answers
Answer: Using y=mx+b
Step-by-step explanation:
Answer:
If there is a graph you can find the rise over run (m = y/x)
but if you have coordinate points you can do y2 - y1 / x2 - x1
(y2 - y1 over x2 - x1 ) which will give you the slope of a line

When sister has a checking account with the account balance ever falls below zero the bank charges her via $5.95 per day today found the balance in Lynn sisters account is -$2.67 if she does not make any deposits or withdrawals what will be the balance in your account after two days
Answers
Answer:
$-14.57
Step-by-step explanation:
the account is already below the zero limit, so for each day the account is below the required balance, there would be a charge of $5.95
After 2 days, the charge would be = $5.95 x 2 = $11.90
So, she would have to pay $11.90
Because she would be paying $11.90, there would be a negative sign in front of the amount
Total balance = $-11.90 -2.67 = $-14.57

Scientists know that the diameter of a normal cell is 0.000025 cm. How is that number written in scientific notation? please help
Answers
Answer:
2.5 * 10^-5 cm
Step-by-step explanation:
Scientists know that the diameter of a normal cell is 0.000025 cm. How is that number written in scientific notation? please help
Given that:
Diameter of a Normal cell = 0.000025 cm
In standard form:
Count the spaces in between each digit from right to left until the point where the decimal point is located.
The number of spaces in between each digit = 6
Since the spaces are counted backwards, the power notation takes a negative (-) sign.
0.000025 is thus rewritten as :
0.000025 = 25 * 10^-6
To place a decimal point in between 25 and rewrite as 2.5,
We the write as :
2.5 * 10^-5 cm

this is because you do 57+89=146
and then you do 180-146 because a triangle adds up to 180.
this gives you 34
so the value of 5x-6=34
add the 6 onto 34 which gets rid of the -6 ans fives you the answer of 40
After that yoy divide 40 by 5 which gives you the value of x which is 8

A 172 ft. Building casts a 444 ft. Shadow from the sun. To the nearest tenth of a degree, what is the angle of depression?
Answers
Answer:
22.77°
Step-by-step explanation:
Using SOH CAH TOA trigonometry identity
Height of the building (opposite side) = 172ft
Length of the shadow (hypotenuse) = 444ft
Using SOH
sin theta = opp/hyp
Sin theta = 172/444
Sin theta = 0.387
theta = arcsin0.387
theta = 22.77°
Hence the angle of depression is 22.77°

7th grade: A jewelry salesperson sells an
engagement ring for $6200. They earn a
16% commission. How much money does
the salesperson keep? How much does
the company keep?
Answers
Answer:
The salesperson keeps $922/The company keeps $5278
Step-by-step explanation:
16% of $6200
.16x6200= 992
The salesperson keeps $922
6200-922= 5278
The company keeps $5278
Answer:
The salesperson keeps $992 and the company keeps $5208.
Step-by-step explanation:
All you have to do to find the amount the salesperson keeps is find 16% of $6200, so to do that first convert the percent to a decimal, so 16% = 0.16. Then, you just do 0.16 * 6200 = $992.
To find how much the company keeps, do the total amount - the amount for the salesperson, so 6200 - 992 = $5208.
