Anyone knows how to do this
Answer:
length = x - 2
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × width
Here A = x² - 7x + 10 and width = x - 5
x² - 7x + 10 = length × (x - 5) ← divide both sides by (x - 5)
length = [tex]\frac{x^2-7x+10}{x-5}[/tex] ← factor the numerator
= [tex]\frac{(x-5)(x-2)}{x-5}[/tex] ← cancel common factor (x - 5) on numerator/ denominator
= x - 2
Thus length = x - 2 metres

Answer:
Part 1) The volume of the storage body is 576 cubic feet
Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box
Part 3) Sheila can fit 64 boxes into the truck
Step-by-step explanation:
step 1
Find the volume of the storage body
we know that
The volume of the of the storage body is equal to the volume of two rectangular prism
The volume of a rectangular prism is equal to
[tex]V=LWH[/tex]
First rectangular prism (top)
[tex]V=(15)(6)(8-6)=180\ ft^3[/tex]
Second rectangular prism (bottom)
[tex]V=(15-4)(6)(6)=396\ ft^3[/tex]
The volume of the storage body is
[tex]V=180+396=576\ ft^3[/tex]
step 2
we know that
To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box
step 3
substitute the given values
[tex]\frac{576}{9}= 64\ boxes[/tex]
therefore

at age 27, jill deposited $4,000 into an ira, where it earns 9.8% interest compounded monthly. what will it be worth when she is thirty-five?
The amount when she is 35 is $8,733.01221.
Given that,
The deposited amount is $4,000.The rate of interest is 9.8%.The time is 8 years.Based on the above information, the calculation is as follows:
[tex]= \$4,000 \times (1 + 9.8\%\div 12)^{8\times 12}\\\\= \$4,000 \times (12.098\div 12)^{96}[/tex]

Final answer:
At age 35, Jill's IRA investment, which started with a $4,000 deposit at age 27 and earns 9.8% interest compounded monthly, will be worth approximately $8,159.55.
Explanation:
To determine the future value of Jill's IRA investment, we will use the formula for compound interest, which is A = [tex]P(1 + \(\frac{r}{n}\))^n^t[/tex], where:
P is the principal amount (the initial amount of money)
r is the annual interest rate (decimal)
n is the number of times that interest is compounded per year
t is the time the money is invested for in years
A is the amount of money accumulated after n years, including interest.
In Jill's case, she deposited $4,000 into an IRA at age 27, and we want to find out what it will be worth when she is 35. The annual interest rate is 9.8%, but since it is compounded monthly, we will have to convert this to a monthly rate and adjust the time accordingly
The steps to solve for the amount A are as follows:
Convert the annual interest rate to a decimal: 9.8% = 0.098
Find the monthly interest rate by dividing the annual rate by 12: \[tex](\frac{0.098}{12}\)[/tex]
Calculate the number of years money is invested: 35 - 27 = 8 years
Find the number of times interest is compounded: 12 months/year × 8 years
Use the compound interest formula to calculate A.
Now, let's do the math:
P = $4,000
r = 0.098 / 12
n = 12
t = 8
A = 4000(1 + [tex]\(\frac{0.098}{12}\))^(12\(\times\)8)[/tex]
Using a calculator we get:
A = $4000(1 + 0.0081667)⁹⁶
A = $4000(1.0081667)⁹⁶
A = $4000 [tex]\(\times\)[/tex] 2.0398873
A ≈ $8,159.55
Therefore, at age 35, Jill's IRA investment will be worth approximately $8,159.55.

A plastic storage bin is shaped like a rectangle or prism. The height of the band is 9 inches. The bottom of the band has an area of 180 in.². What is the volume of the storage bin
Answer:
v = 1620 ^3
Step-by-step explanation:
If the area of the bottom is 180 sq in and the height is 9 in then this is how you would solve the problem.
To get area of the volume is l * w * h
Because of the associative property we can do this in any order we want
If we know that l * w is 180, then all we have to do is multiply 180 by 9
180 * 9 = 1620

What is this limit? Without using lopital rule
Answer:
60.
Step-by-step explanation:
(x^2 - 25) / (√(x + 4) - 3).
We rationalise the expression by multiplying top and bottom of the fraction by the complement of the denominator.
That is by (√(x + 4) + 3):
(x^2 - 25)(√(x + 4) + 3)
= ------------------------------------
(√(x + 4) - 3)(√(x + 4) + 3)
= (x + 5)(x - 5)(√(x + 4) + 3)
----------------------------------
(x - 5)
= (x + 5)(√(x + 4) + 3).
The limit as this---> 5
is (5 + 5)(√(5 + 4) + 3)
= 10 * 6
= 60.
Find the equation of the axis of symmetry for this function
F(x)= 5x^2 - 3x + 5
Answer:
x = [tex]\frac{3}{10}[/tex]
Step-by-step explanation:
Given a quadratic in standard form, ax² + bx + c : a ≠ 0
Then the axis of symmetry is a vertical line with equation x = h
where h is the x- coordinate of the vertex.
The x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = 5x² - 3x + 5 ← is in standard form
with a = 5 and b = - 3, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{-3}{10}[/tex] = [tex]\frac{3}{10}[/tex]
Thus the equation of the axis of symmetry is x = [tex]\frac{3}{10}[/tex]
