Jermaine earned $2000 during the summer. He plans to put the money in a
savings account and leave it for 40 years. The account will earn 9% simple
interest annually. What will the balance be after 40 years?
Please help!! This is a test and I need a good grade!!
Answer:9200
Step-by-step explanation: .09 * 2000 = 180 * 40 = 7200 + 2000 = 9200
Balance amount in Jermaine account after 40 years is equals to $9200.
What is simple interest?" Simple interest is the process of calculating amount of interest given on the principal amount at the rate of interest over period of time."
Formula used
S.I. = = (P × R × T) / 100
S.I.= Simple Interest
P = Principal amount
R = Rate of interest
T = Time
Total amount = P + S.I.
According to the question,
Given
P = $2000
R = 9%
T = 40 years
Substitute the given values in the formula we have,
Simple Interest = (2000 × 9 × 40) / 100
= $7200
Total balance amount after 40 years = $2000 + $ 7200
= $9200
Hence, balance amount after 40 years is equals to $9200.

Which of the functions below is an inverse of the quadratic function f(x) = x2 - 3 ?
Answer:
the inverse of the quadratic function [tex]f(x) = x^2 - 3[/tex] is [tex]\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}[/tex]
Step-by-step explanation:
We need to find inverse of the quadratic function [tex]f(x) = x^2 - 3[/tex]
Let
[tex]y=x^2-3[/tex]
Replace x and y
[tex]x=y^2-3[/tex]
Now, we will solve for y
Adding 3 on both sides
[tex]x+3=y^2-3+3[/tex]
[tex]x+3=y^2[/tex]
Taking square root on both sides
[tex]\sqrt{y^2}=\sqrt{x+3}\\y=\pm \sqrt{x+3}[/tex]
Now replace y with [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x)=\pm \sqrt{x+3}[/tex]
So, the inverse of the quadratic function [tex]f(x) = x^2 - 3[/tex] is [tex]\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}[/tex]
Solve for b. ax+3b=2f
b = [tex]\frac{2f}{3}[/tex] - [tex]\frac{ax}{3}[/tex]

Hi, I am trying to find the Area but I cant tell if its 2D or 3D help please!
pls answer to become the brainliest
Answer:
37.50 square centimeters
Step-by-step explanation:
The computation of the area of the sector is as follows:
As we know that
Area of the circle is
= πr^2
Since the radius is 10 cm so the area of total circle is
= 3.14 × 100
= 314
Also it is 360 degrees
So, the area of the sector is
= 135 ÷ 360 × 1200
= 37.50 square centimeters

The total (after-tax) cost of a laptop computer is $1571.02. The local sales tax rate is 5.3%. What is the retail (pre-tax)
price?
Answer:
Retail price of laptop = $1491.94
Step-by-step explanation:
Price of laptop after tax = $1571.02
Local sales tax rate = 5.3%
Total price = Pre tax price + tax = (100+5.3)%
Total price = 105.3%
Let,
x be the pre-tax price
105.3% of x = 1571.02
[tex]\frac{105.3}{100}x=1571.02[/tex]
1.053x = 1571.02
[tex]\frac{1.053x}{1.053}=\frac{1571.02}{1.053}\\x=1491.94[/tex]
Retail price of laptop = $1491.94

Answer:
a) The equation of V and W
V = k W
b) The value of V = 666.6
Step-by-step explanation:
Step(i):-
Given that V is inversely proportional to W
V∝ W
⇒ V = k W
⇒ 40 = k (0.9)
⇒ [tex]k = \frac{40}{0.9} = 44.44[/tex]
Step(ii):-
Given that W = 15 and k = 44.44
we have to find the value is 'V'
V = k W
⇒ V = 44.44 × 15
⇒ V = 666.6
