Answer:
[tex] \bf \huge ± 5 [/tex]
Step-by-step explanation:
Given :- x^ 2 - 8 = - 33to find :find ''x''explanation :⟼ - x^ 2 - 8 = - 33
step 1 : add 8 to both sides
⟼ − x² − 8 + 8 = − 33 + 8
⟼ - x² = - 25
step 2 : Divide both sides by -1
⟼ - x² / - 1 = - 25 / - 1
⟼ x² = 25
step 3 : take square root
⟼ x² = 25
⟼ x = ± √25
⟼ x = ± 5
∴ x = ± 5.

A rake was marked up 25% from an original cost of $8.80. Last Friday, Dean bought the rake and paid an additional 3% in sales tax. What was his total cost?
Answer:
$11.33
Step-by-step explanation:
First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33
The total cost of the rake is $11.33.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Given that, a rake was marked up 25% from an original cost of $8.80.
25% of the original cost of $8.80 is
0.25×8.80 =$2.2
So the marked up price was 8.80+2.20
= $11
He then paid an additional 3% in sales tax, that is
11 + 0.03×11 = $11.33
Therefore, the total cost of the rake is $11.33.

Step-by-step explanation:
Grace and her brother need $400 to go to band camp. Their parents have agreed
to help them earn money by paying them $25 each time they mow the lawn
and $10 for each hour they babysit their younger brother. They will have to do a
combination of both chores to earn the money.
Select the equation that represents the number of lawns they can mow, m, and
hours they can babysit, b, to earn $400.
M. 10m + 25b = 400
P.
10m - 25b = 400
R. 25m + 10b = 400
S. 25m - 10b = 400
Answer:
R. 25m + 10b = 400
Step-by-step explanation:
25m: $25 for time the mow the lawn
10b: $10 for every hour that they babysit their younger brother
400: They need $400 in total
+ : You need to add what they made for mowing the lawn and for babysitting.
Find the difference of the complex numbers.
(2 +8i)-(-5 - 3i)
Answer:
7 + 11i
Step-by-step explanation:
Simplify: (2 +8i)-(-5 - 3i) = 2 + 8i + 5 + 3i
Add real numbers to real numbers and imaginary to imaginary: 2 + 8i + 5 + 3i = 7 + 11i
A complex number can be shown as a pair of integers (a, b). The difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.
What is a complex number?A complex number can be shown as a pair of integers (a, b) forming a vector on an Argand diagram, which represents the complex plane.
The difference of the complex number can be done as following,
(2+8i)-(-5-3i)
= 2 + 8i + 5 + 3i
= 5+2 + 8i+3i
= 7 + 11i
Hence, the difference of the complex number (2 +8i)-(-5 - 3i) is 7+11i.

determine the intercepts of the line
Answer:
(0, -5/2), (-2, 0)
Step-by-step explanation:
To find the y-intercept, set x = to 0 and find y: -4y = 10. Thus, y = -5/2. The y-intercept is (0, -5/2).
To find the x-intercept, set y = to 0 and fid x: -5x = 10. Therefore the x-intercept is -2: (-2, 0)

Answer:
That would be -2n - 1.
Answer:
-2n - 1
Step-by-step explanation:
You have to combine like term which would be 4n,n,and 7n.
Since n doesn't have a variable just add a one in front. So now the equation would be
1n+4n-7n That equation equals -2n
Now just add the remaining number
So that makes the answer -2n -1

"You purchase a vintage car for $140,000 and it appreciates (i.E. Increases in value) by 4% annually. How much will the car be worth in 10 years?"
Answer:
Future Value= $207,234.2
Step-by-step explanation:
Giving the following formula:
Initial value (PV)= $140,000
Appreciation rate (r)= 4% = 0.04
Number of years (n)= 10
To calculate the future value of the car after ten years, we need to use the following formula:
FV= PV*(1+i)^n
FV= 140,000*(1.04^10)
FV= $207,234.2
The angle of elevation of an electricity pole from a point 8 metres from its base is 52.7 degrees. What is the height of the pole?
Answer:
10.5m
Step-by-step explanation:
We solve the above question, using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 52.7 °
Adjacent = 8 m
Opposite = x
Hence,
tan 52.7= x/8m
Cross Multiply
x = tan 52.7 × 8m
x = 10.501501092m
Approximately = 10.5 m
Therefore, the height of the pole = 10.5m
