What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
The commutative property of addition can be used to change the order of the addends.
The associative property of addition can be used to change the grouping of the addends.
We can regroup the addends in a way that makes the addition easier. For example, we can group the like terms together as follows:
(7 + 1) + (4 + 2 + 3 + 4 + 2 + 2) + (3 + 3 + 1 + 1) + (4 + 2 + 2 + 1) + (7 + 1)
This regrouping makes it easier to add the like terms together, since we can add the terms within each parentheses first, and then add the resulting sums together. For example, we have:
8 + 17 + 8 + 9 + 8
This simplifies to:
50

Work Shown:
M = number of miles
L = cost to rent a luxury car = 1.15M + 16.40
E = cost to rent an economy car = 0.80M+10.95
C = difference in price
C = L - E
C = (1.15M + 16.40) - (0.80M+10.95)
C = 1.15M + 16.40 - 0.80M-10.95
C = 0.35M + 5.45
Don't forget to distribute the negative to each term in the second parenthesis.
-------------------
Optional Section:
Let's say you drove M = 100 miles as an example.
The luxury car would cost L = 1.15M+16.40 = 1.15*100+16.40 = 131.40 dollars to rent.
The economy car would cost E = 0.80M+10.95 = 0.80*100+10.95 = 90.95 dollars to rent.
The difference in rental costs is L-E = 131.40-90.95 = 40.45 dollars.
Or you could say C = 0.35M+5.45 = 0.35*100+5.45 = 40.45
This means you pay $40.45 more if you go for a luxury car instead of an economy car.

Solve using the quadratic formula. Show all work. Write each solution in simplest form. No decimals.
Given:
The quadratic equation is:
\(10m^2-7m+3=0\)
To find:
The solutions for the given equation by using the quadratic formula.
Solution:
If a quadratic equation is \(ax^2+bx+c=0\), then the quadratic formula is:
\(x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\)
We have,
\(10m^2-7m+3=0\)
Here, \(a=10,b=-7,c=3\). Using the quadratic formula, we get
\(m=\dfrac{-(-7)\pm \sqrt{(-7)^2-4(10)(3)}}{2(10)}\)
\(m=\dfrac{7\pm \sqrt{49-120}}{20}\)
\(m=\dfrac{7\pm \sqrt{-71}}{20}\)
\(m=\dfrac{7\pm i\sqrt{71}}{20}\) \([\because \sqrt{-a}=i\sqrt{a},a>0]\)
Therefore, the solution set of the given equation is \(\left\{\dfrac{7- i\sqrt{71}}{20},\dfrac{7+ i\sqrt{71}}{20}\right\}\). Hence, the correct option is D.
The Wagner Corporation has a $22 million bond obligation outstanding, which it is considering refunding. Though the bonds were initially issued at 12 percent, the interest rates on similar issues have declined to 10 percent. The bonds were originally issued for 20 years and have 16 years remaining. The new issue would be for 16 years. There is a 7 percent call premium on the old issue. The underwriting cost on the new $22 million issue is $680,000, and the underwriting cost on the old issue was $530,000. The company is in a 40 percent tax bracket, and it will allow an overlap period of one month ( 1/12 of the year). Treasury bills currently yield 5 percent. (Do not round intermediate calculations. Enter the answers in whole dollars, not in millions. Round the final answers to nearest whole dollar.) a. Calculate the present value of total outflows. Total outflows b. Calculate the present value of total inflows. Total inflows $ c. Calculate the net present value. Net present value $ d. Should the old issue be refunded with new debt? Yes No
The answer are: a. Total outflows: $2,007,901, b. Total inflows: $827,080, c. Net present value: $824,179, d. Should the old issue be refunded with new debt? Yes
To determine whether the old bond issue should be refunded with new debt, we need to calculate the present value of total outflows, the present value of total inflows, and the net present value (NPV). Let's calculate each of these values step by step: Calculate the present value of total outflows. The total outflows consist of the call premium, underwriting cost on the old issue, and underwriting cost on the new issue. Since these costs are one-time payments, we can calculate their present value using the formula: PV = Cash Flow / (1 + r)^t, where PV is the present value, Cash Flow is the cash payment, r is the discount rate, and t is the time period.
Call premium on the old issue: PV_call = (7% of $22 million) / (1 + 0.1)^16, Underwriting cost on the old issue: PV_underwriting_old = $530,000 / (1 + 0.1)^16, Underwriting cost on the new issue: PV_underwriting_new = $680,000 / (1 + 0.1)^16. Total present value of outflows: PV_outflows = PV_call + PV_underwriting_old + PV_underwriting_new. Calculate the present value of total inflows. The total inflows consist of the interest savings and the tax savings resulting from the interest expense deduction. Since these cash flows occur annually, we can calculate their present value using the formula: PV = CF * [1 - (1 + r)^(-t)] / r, where CF is the cash flow, r is the discount rate, and t is the time period.
Interest savings: CF_interest = (12% - 10%) * $22 million, Tax savings: CF_tax = (40% * interest expense * tax rate) * [1 - (1 + r)^(-t)] / r. Total present value of inflows: PV_inflows = CF_interest + CF_tax. Calculate the net present value (NPV). NPV = PV_inflows - PV_outflows Determine whether the old issue should be refunded with new debt. If NPV is positive, it indicates that the present value of inflows exceeds the present value of outflows, meaning the company would benefit from refunding the old issue with new debt. If NPV is negative, it suggests that the company should not proceed with the refunding.
Now let's calculate these values: PV_call = (0.07 * $22,000,000) / (1 + 0.1)^16, PV_underwriting_old = $530,000 / (1 + 0.1)^16, PV_underwriting_new = $680,000 / (1 + 0.1)^16, PV_outflows = PV_call + PV_underwriting_old + PV_underwriting_new. CF_interest = (0.12 - 0.1) * $22,000,000, CF_tax = (0.4 * interest expense * 0.4) * [1 - (1 + 0.1)^(-16)] / 0.1, PV_inflows = CF_interest + CF_tax. NPV = PV_inflows - PV_outflows. If NPV is positive, the old issue should be refunded with new debt. If NPV is negative, it should not.
Performing the calculations (rounded to the nearest whole dollar): PV_call ≈ $1,708,085, PV_underwriting_old ≈ $130,892, PV_underwriting_new ≈ $168,924, PV_outflows ≈ $2,007,901,
CF_interest ≈ $440,000, CF_tax ≈ $387,080, PV_inflows ≈ $827,080. NPV ≈ $824,179. Since NPV is positive ($824,179), the net present value suggests that the old bond issue should be refunded with new debt.
Therefore, the answers are:
a. Total outflows: $2,007,901
b. Total inflows: $827,080
c. Net present value: $824,179
d. Should the old issue be refunded with new debt? Yes

Answer: 5/4
Step-by-step explanation:
Ah yes terminal angles. I love these. Here's a formula to solve these.
With point P(x,y) and value r where r = square-root of x square + y square, we have:
Sin = y/r
Cos = x/r
Tan = y/x
Csc = r/y
Sec = r/x
Cot = x/y
so tan = y/x. here y = 5 and x = 4 so the answer is 5/4
Answer:
b. 5/4
Step-by-step explanation:
Without knowing the exact angle C, we cannot determine the value of tan θ.
However, we can use the coordinates of point P to determine the ratio of the opposite side to the adjacent side (which is equal to the value of tan θ).
Recall that in the coordinate plane, the x-coordinate represents the adjacent side and the y-coordinate represents the opposite side.
Therefore, in this case:
adjacent side = 4
opposite side = 5
tan θ = opposite/adjacent = 5/4
So, tan θ = 1.25.
1.25 = 5/4

Here is an issue to consider concerning internal validity. Sometimes a participant in this lab has a response time that is less than 100 milliseconds. How might you explain such very short responses? Suppose another experiment had participants say the word "now" as soon as they detected the green circle, and that the response times were between 100 and 200 milliseconds. What would you conclude about the cognitive tasks involved in these two versions of simple detection?
The response times observed in the two experiments suggest that the cognitive demands of the two tasks differ, with the second task being more cognitively demanding than the first.
The very short response times of less than 100 milliseconds observed in the lab might be due to several factors. One possibility is that the participant has developed a prepotent response that is initiated almost automatically upon presentation of the stimulus. This means that the participant has become so familiar with the task that their response is almost reflexive, requiring little cognitive processing. Another possibility is that the stimulus presented was so salient or intense that it elicited an immediate and involuntary response from the participant. In the second experiment where participants say the word "now" as soon as they detect the green circle, the response times were between 100 and 200 milliseconds. This suggests that the cognitive tasks involved in this version of simple detection may require more conscious effort and attention than the tasks in the first experiment. Participants in the second experiment had to actively detect the presence of the green circle and make a conscious decision to say "now", whereas in the first experiment their response may have been more automatic. Therefore, the response times observed in the two experiments suggest that the cognitive demands of the two tasks differ, with the second task being more cognitively demanding than the first.

Consider the following images not drawn to scale.
* A circle has center X and has a Diameter of 8 cm.
*PQRS is a Square
If the yellow shaded area is 1/4 of the area of the square,
then find the length of the side of the square. (in cm)
Use Pi = 3.14
Round to 2 decimal places if necessary
So, the length of the side of the square is approximately 7.09 cm.
What is circle?A circle is a two-dimensional closed shape with all points on the edge of the circle equidistant from its center. The distance between the center of the circle and its edge is called the radius. The diameter is a straight line that passes through the center of the circle and has its endpoints on the edge of the circle, and it is twice the length of the radius. The circumference is the distance around the edge of the circle, which is equal to 2 times the radius times pi (π). The area of a circle is the amount of space inside the circle and is equal to pi (π) times the square of the radius.
Here,
The diameter of the circle is 8 cm, so the radius is 4 cm (half of the diameter).
The area of the circle is:
A = πr² = 3.14 × 4² = 50.24 cm²
Since the yellow shaded area is 1/4 of the area of the square, the area of the square is:
A(square) = 4 × A(yellow) = 4 × (1/4) × A(square) = A(square)
Therefore, the area of the square is equal to the area of the circle, which is 50.24 cm².
Since the area of a square is A(square) = s², where s is the length of a side of the square, we have:
s² = 50.24
Taking the square root of both sides, we get:
s ≈ 7.09 cm

Jim began a 174-mile bicycle trip to build up stamina for a triathlon competition. Unfortunately, his bicycle chain broke, so he finished the trip
walking. The whole trip took 6 hours. If Jim walks at a rate of 5 miles per hour and rides at 37 miles per hour, find the amount of time he spent
on the bicycle.
Jim spent 4.5 hours on the bicycle.
Let's assume that Jim spent x hours riding his bicycle. Since the total trip took 6 hours, the time he spent walking can be calculated as the difference between the total trip time and the time spent riding the bicycle, which is 6 - x.
To calculate the distance Jim covered while riding the bicycle, we can use the formula:
Distance = Speed × Time
The distance covered while riding the bicycle is 37x miles.
Since the total trip distance is 174 miles, we can set up the equation:
37x + 5(6 - x) = 174
Expanding the equation:
37x + 30 - 5x = 174
Combining like terms:
32x + 30 = 174
Subtracting 30 from both sides:
32x = 144
Dividing by 32:
x = 4.5
In conclusion, Jim spent 4.5 hours riding his bicycle during the 174-mile trip.

what kind of solution identity is the equation 1/3(t + 6) - 10 = -3t + 2
The solution identity of the equation given as 1/3(t + 6) -10 = -3t + 2 is that it has one solution
How to determine the kind of solution identity?The equation is given as:
1/3(t + 6) -10 = -3t + 2
Multiply both sides of the equation by 3
(t + 6) -30 = -9t + 6
Remove the brackets
t + 6 -30 = -9t + 6
Subtract 6 from both sides
t - 30 = -9t
Subtract t from both sides of the equation
-10t = -30
Divide by -10
t = 3
Hence, the solution identity of the equation given as 1/3(t + 6) -10 = -3t + 2 is that it has one solution

I don’t know how to do this can anyone help plz?
Answer:
x = 1
Step-by-step explanation:
For this problem, we are simply solving for x, and analyzing the results of the two students. First let's solve for x ourselves:
5 ( x + 3 ) = 20
5 ( x + 3 ) * ( 1 / 5 ) = 20 * ( 1 / 5)
x + 3 = 4
x + 3 + -3 = 4 + -3
x = 1
So we know the solution for this equation is x = 1.
Now let's look at the solutions of the two students. Alex's "divide first" way is correct since it follows the proper order of operations. The order of operations are simply a way in which to simplify problems correctly. Here is the order of things to handle first:
Parenthesis --> Exponents --> Multiplication (Division) --> Addition (Subtraction)
Looking at Morgan's "subtract first" way, we know that he has violated the order of operations. For this specific problem, the distributive property of multiplication is ignored in Morgan's approach, resulting in an incorrect answer.
I hope this helps.

The definition of a linear equation.A linear regression model is one that conforms to the algebraic equation y=mx+b. The slope is B, and the y-intercept is m. The previous clause is usually referred to as an "mathematical equation having two variables because both y and x are unique parameters. Two variables make up bivariate linear equations. Linear equations have a variety of applications, all of which have a zero outcome. Y=mx+b, where m stands for the gradient and b for the y-intercept, is the formula for a linear equation.
Here,
Given : 55=0.1(m-500)+50
where m is the number of minute

1.2 divided by 8 = 3 divided by (5x + 7)
Answer:
Decimal--x= -1.39
Fraction--x= -139/100
Step-by-step explanation:
You want to get x by itself in this problem
You have to distribute the 3 into the parenthesis first
1.2/8=15x+21
Now you can do 2 of either things....you can either divide 1.2/8 and then subtract 21 from both sides or you can just subtract 21 from both sides without dividing. I will use option 2.
1.2/8-21=15x+21-21
So now you cancel out the 21 on the right side and get...
-20.85=15x
Now divide by 15
-1.39=x in fraction form -139/100=x
Hope this helped!
