Step-by-step explanation:
An investor has an account with stock from two different companies. Last year, her
stock in Company A was worth $800 and her stock in Company B was worth $6180.
The stock in Company A has decreased 1% since last year and the stock in Company B
has decreased 5%. What was the total percentage decrease in the investor's stock
account? Round your answer to the nearest tenth (if necessary).
Answer:
4.5%
Step-by-step explanation:
800(1-0.01)=\color{green}{792}
800(1−0.01)=792
6180(1-0.05)=\color{blue}{5871}
6180(1−0.05)=5871
Last Year This Year
Stock A 800 792
Stock B 6180 5871
Total 6980 6663
\text{Find overall decrease:}
Find overall decrease:
6980(1-r)=6663
6980(1−r)=6663
\frac{6980(1-r)}{6980}=\frac{6663}{6980}
6980
6980(1−r)
=
6980
6663
1-r=0.954585
1−r=0.954585
-r=-0.045415
−r=−0.045415
Subtract 1
r=0.045415
r=0.045415
Divide by -1
\text{Final Answer: }4.5\%
Final Answer: 4.5%

A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining to be paid. The graduate makes regular payments of $8,000 each year. The graph shows the sequence. f(x)=?
Answer:
The equation is: [tex]f(x) = 52000 - 8000x[/tex]
Step-by-step explanation:
Given
Initial = 52000
Rate = 8000 each year
Required
Determine the equation of the graph
The equation can be determined using.
[tex]Amount = Initial - Rate* Years[/tex]
We used minus (-) because, the amount reduces as the student pays.
Let
[tex]y = Amount[/tex]
[tex]x = Years[/tex]
So, we have:
[tex]y = Initial - Rate * x[/tex]
Substitute values for Initial and Rate
[tex]y = 52000 - 8000 * x[/tex]
[tex]y = 52000 - 8000x[/tex]
Express as a function:
[tex]f(x) = 52000 - 8000x[/tex]
Determine the axis of symmetry of the Quadratic equation.

George bought a car at $5000 and sold it at $5500. What benefit, in percent, did he
make?
a. 500%
b. 10%
C. 5000%
0.5%
The benefit in the percentage did he make at the time of purchasing and selling the car is 10%.
Calculation of the percentage:Since George bought a car at $5000 and sold it at $5500
So, the profit percentage be like
[tex]= (5500 - 5000) \div 5000[/tex]
= 10%
hence, The benefit in the percentage did he make at the time of purchasing and selling the car is 10%.

Step-by-step explanation:
For 1A
2y + 98° = 9y + 7° < being vertically opposite angles >
9y - 2y = 98° - 7°
7y = 91°
y = 13°
For 1B
9y + 7° = 9 * 13° + 7° = 124°
2y + 98° = 2 * 13° + 98° = 124°
The angles which are unknown are also vertically opposite angles so let unknown angles be x then
124° + 124 ° + x +x = 360° { being complete turn }
248° + 2x = 360°
2x = 112°
x = 56°
so all angles are 124° , 124° , 56°, 56°
For 2A
6y - 10 + 6y + 10 = 180° ( being linear pair)
12y = 180°
y= 15°
For 2B
6y - 10 = 6 * 15 - 10 = 80°
6y + 10 = 6 * 15 + 10 = 100°

Answer:
[tex]y = 40000(1.02)^8[/tex]
Step-by-step explanation:
Given
[tex]a = 40000[/tex] -- Initial population
[tex]r = 2\%[/tex] --- Rate
Required
Determine the population in 8 years
The question shows an exponential distribution and the final population will be calculated using:
[tex]y = a(1 + r)^x[/tex]
Where x is the number of years.
So, we have:
[tex]y = 40000(1 + 2\%)^8[/tex]
Convert % to decimal
[tex]y = 40000(1 + 0.02)^8[/tex]
[tex]y = 40000(1.02)^8[/tex]

What is the volume, in cubic cm, of a rectangular prism with a height of 8cm, a width of 2cm, and a length of 7cm?
Please , help .
Answer:
v = A x H = LxW xH = 7cm x 2cm x 8cm =112CM^3
Answer:
112 cm³
Step-by-step explanation:
In this question, we have to find the volume of a rectangular prism.
The formula to find the volume of a rectangular prism would be: V = L × W × H
To find the volume, plug in the values and solve.
Solve:
V = 7 × 2 × 8
V = 14 × 8
V = 112
This means that the volume of the rectangular prism is 112 cm³
Remember, volume is always represented with a exponent of 3, or cubed, in the unit.
Your answer would be 112 cm³
