Answer:
a: 3/2, -2 b: 1/5, -1/2 c: 3/2, -4
Step-by-step explanation:
a: 2x^2+x=6
Subtract 6 from both sides.
2x^2+x−6=6−6
2x^2+x−6=0
Factor left side of equation.
(2x−3)(x+2)=0
Set factors equal to 0.
2x−3=0 or x+2=0
b: 10a^2+3a=1
Subtract 1 from both sides.
10a^2+3a−1=1−1
10a^2+3a−1=0
Factor left side of equation.
(5a−1)(2a+1)=0
Set factors equal to 0.
5a−1=0 or 2a+1=0
c: 2c^2+5c=12
Subtract 12 from both sides.
2c^2+5c−12=12−12
2c^2+5c−12=0
Factor left side of equation.
(2c−3)(c+4)=0
Set factors equal to 0.
2c−3=0 or c+4=0

Balloons By Sunset (BBS) is considering the purchase of two new hot air balloons so that it can expand its desert sunset tours. Various information about the proposed investment follows: (Future Value of $1, Present Value of $1, Future Value Annuity of $1, Present Value Annuity of $1.) (Use appropriate factor(s) from the tables provided.)
Initial investment (for two hot air balloons) $ 399,000
Useful life 9 years
Salvage value $ 48,000
Annual net income generated 30,324
BBS’s cost of capital 8 %
Assume straight line depreciation method is used.
Required:
Help BBS evaluate this project by calculating each of the following:
1. Accounting rate of return. (Round your answer to 2 decimal places.)
2. Payback period. (Round your answer to 2 decimal places.)
3. Net present value (NPV). (Do not round intermediate calculations. Negative amount should be indicated by a minus sign. Round the final answer to nearest whole dollar.)
4. Recalculate the NPV assuming BBS's cost of capital is 11 percent. (Do not round intermediate calculations. Negative amount should be indicated by a minus sign. Round the final answer to nearest whole dollar.)
I'm mostly confused on NPV
The accounting rate of return is 7.6%, the payback period is 5.755 years, the Net present value is $58,072, and the net present value(11%) is $3611.
What is NPV?The Net Present Value (NPV) is a corporate finance technique for analyzing the viability of an investment or a firm. It's the disparity between the anticipated cash flows and the initial investment. Let's look more closely at NPV.
We can calculate the accounting rate of return as follows:
Accounting rate of return = (Annual net Income/ Average Investment)×100
=(30,324/399,000)×100
= 7.6%
For Payback period:
Payback = Initial investment/ Annul cash flow
Annual cash flow = Annual net income + Depreciation
Deprecition = cost - salvage value/useful life
= (399,000-48,000)/9
= $39,000
Annual cash flow = 30,324 + 39,000 = 69324
Payback= 399,000/69324
= 5.755 years
For NPV:
NPV = Total present value of investment - initial investment
= 69324×PVIFA(8%, 9 years)+48,000×PV(8%, 9 years) - 399,000
= 69324×6.2469+24,011.95 - 399,000
= $58,072
For Net value recalculate if the cost of capital is 11%
NPV = Total present value of investment - initial investment
= 69324×PVIFA(11%, 9 years)+48,000×PV(11%, 9 years) - 399,000
= 69324×5.5370+18,764.39 - 399,000
= 3610.988
= $3611
Thus, the accounting rate of return is 7.6%, the payback period is 5.755 years, the Net present value is $58,072, and the net present value(11%) is $3611.

Answer:
Step-by-step explanation:
Finding the center.
The general formula for a circle is
(x - a)^2 + (y - b)^2 = r^2
The center is a and b. The center is marked as (6,5)
So the equation becomes
(x - 6)^2 + (y - 5)^2 = r^2
Finding the radius
The radius is found by calculating the distance between the center and any point on the circumference.
The point given on the circumference is (8,8)
x1 = 8
x2 = 6
y1 = 8
y2 = 5
r^2 = (8 - 6)^2 + (8 - 5)^2
r^2 = 2^2 + 3^2
r^2 = 4 + 9
r^2 = 13
Answer
(x - 6)^2 + (y - 5)^2 = 13

From actual road tests with the tires, Hankook Tires estimated that the mean fire mileage is 36,500 miles and that the standard deviation is 5000 miles. Data is normally distributed. What percentage of the tires can be expected to last more than 40,000 miles? Assume that Hankook Tires is considering a guarantee that will provide a discount on replacement tires if the original tires do not provide the guaranteed mileage. What should the guarantee mileage be if the company wants no more than 10% of the tires to be eligible for the discount guaranfee? UNIVER

Find the Value of X. or other X finders. (worth 10 points)
Answer:
First, if we look at these angles, we can see that they are vertical.
Vertical angles are congruent(meaning they measure the same degrees).
So let's set up an equation where -2x - 6 is equal to 40°, because they are vertical angles.
-2x - 6 = 40°
Solve for x!
Get rid of constants by performing the inverse operation of subtraction which is addition(because 6 is negative).
Make sure to apply this to both sides!!
(Add 6 to both sides)
+6 +6
-2x = 46
Now, we isolate x by getting of x's co-efficient.
To do that, we also perform the inverse operations.
The inverse operation of multiplication is division (since -2 is being multiplied by x).
(Divide -2 from both sides)
÷ -2 ÷ -2
x = -23
Therefore, x measures -23°.
Answer:
x = -23
Step-by-step explanation:
Vertical Angle Theorem
A pair of opposite angles formed by intersecting lines.
Vertical angles are congruent.
⇒ -2x - 6 = 40
Add 6 to both sides:
⇒ -2x = 46
Divide both sides by -2
⇒ x = -23

Answer: (dc)⁶
Step-by-step explanation:
Apply exponent rule: a⁰=1
This means c⁰=1 and d⁰=1 leaving the equation d⁷·c⁻¹
This then becomes d⁷/c though since they don't want a denominator we will have to change it.
Apply quotient rule of exponents: aᵇ÷aⁿ=aᵇ⁻ⁿ
This leaves us with (dc)⁶
12) A job offers you $15 an hour. Your boss
states that a percentage of your check will
be taken out for taxes, and then $35 for
medical insurance and $4 for dental
insurance. If you worked 38 hours, and
your total paycheck (for the week) was
$462.60, what percentage is taken out for
taxes?
Answer:
12%Step-by-step explanation:
Total paycheck before taking out taxes and insurance :
38×15 = 570
Left Amount of money after applying taxes :
570 - 570×(p/100)
= 570×[1 - (p/100)]
= 570×[(100-p)/100]
= (570/100) × [100 - p]
= 5.7 × [100 - p]
After taking out the insurance amounts we can write this equation:
.,7 × [100 - p] - (35+4) = 462.6
⇔ 5.7 × [100 - p] - 39 = 462.6
⇔ 5,7 × [100 - p] = 462.6 + 39
⇔ 5,7 × [100 - p] = 501.6
⇔ 100 - p = 501.6/5.7
⇔ 100 - p = 88
⇔ p = 100 - 88
⇔ p = 12
Out of 260 racers who started the marathon, 232 completed the race, 25 gave up, and 3 were disqualified. What percentage did not complete the marathon?
Answer:
9
Step-by-step explanation:
You're looking for the percentage that "did not complete the marathon" So take the 25 that gave up and the 3 that were disqualified and add those. Then divide 260 by your sum of those groups. Your expresssion should be 260/28 which gives you the decimal 9.28571429. Your answer would be 9 because this question doesn't ask for a decimal answer.

Which expression is equivalent to x^2+7x+12 over x^2-x-12
Answer:
Step-by-step explanation:
Factorize the expression.
Sum = 7
Product = 12
Factors = 4 , 3
4 + 3= 7 & 4*3 = 12
x² + 7x + 12 = x² + 4x + 3x + 4*3
= x(x + 4) + 3(x + 4)
= (x + 4)(x + 3)
Sum = -1
Product = -12
Factors = (-4) , 3
(-4) + 3 = (-1) & (-4)*3 = -12
x² - x - 12 = x² - 4x + 3x - 4*3
= x(x - 4) +3(x - 4)
= (x -4)(x +3)
[tex]\sf \dfrac{x^{2}+7x+12}{x^{2}-x-12}=\dfrac{(x+4)(x + 3)}{(x -4 )(x + 3)}\\\\\bf \text{(x +3) in the numerator and denominator will get cancelled}[/tex]

Answer:
A. 25 books
Step-by-step explanation:
James has 100 comic books and sells 1/4 of his collection. This means that the amount of comic books that he sold is 1/4 of 100 since 100 is the total amount of comic books that he has. To calculate that, we divide 100 by 4 to get 25. Therefore, James sells 25 books.
