Answer:
(f -g)(2) = 14
Step-by-step explanation:
You can write the expression for the composite function as ...
(f -g)(x) = f(x) -g(x) = (3x² +1) -(1 -x)
(f -g)(x) = 3x² +x
Then for x = 2 ...
(f -g)(2) = 3(2²) +2
(f -g)(2) = 14

A woman has 31 coins in her pocket, all of which are dimes and quarters. If the total value of the coins is $ 5.20, how many dimes and how many quarters does she have?
Answer:
D+Q = 31
10D + 25Q = 595
10D + 10Q = 310
subtract to get
15Q = 285 Q = 285/15 = 19 quarters D = 31-19 = 12 dimes
Jane and johnny are running a race. Jane's speed is 1/4 that of Johnny's.
What is Johnny's speed compared to Jane?
Explain.
25%
50%
150%
400%
The right response is 400%. In other words, Johnny moves at four times the pace of Jane.
We must compare the speeds of Johnny and Jane in relation to one another in order to get their ratio. According to the issue, Jane moves at a pace that is 1/4 that of Johnny. In other words, Jane moves at a speed that is one-fourth that of Johnny.
We may compare the speeds as a fraction to figure out the ratio:
Johnny's speed divided by Jane's speed equals 4/1.
This indicates that Johnny is moving at a speed that is four times that of Jane. We can express Johnny's speed as 400% of Jane's speed in percentage terms.

Borland, Inc., has a profit margin of 5.6 percent on sales of $13.6 million. If the firm has debt of $6.4 million and total assets of $9.8 million, what is the firm’s ROA?
Answer:
ROA = 7.77 percent
Step-by-step explanation:
Borland, Inc., has a profit margin of 5.6 percent on sales of $13.6 million
Thus, profit = 5.6% of $13.6 million
profit = 5.6 / 100 * $13.6 million = $0.7616 million
Profit is same as net income
Formula for ROA (return on asset) = net income/ total asset
total asset as given = $9.8 million
Thus, ROA = $0.7616/ $9.8 = 0.0777
ROA in percentage = 0.0777*100 = 7.77
Thus, ROA is 7.77 percent .
Betsy, a recent retiree, requires $6,000 per year in extra income. She has $50,000 to invest and can invest in B-rated bonds paying 13% per year or in a certificate of deposit (CD) paying 3% per year. How much money should be invested in each to realize exactly $6,000 in interest per year?
Answer:
$45,000 at 13% = B-rated bond
$5,000 at 3% = CD
Step-by-step explanation:
Let us assume the x amount at 13% be 0.13x
And, y amount at 3% be 0.03x
Total interest = $6,000
The equation is
0.13x + 0.03x = $6,000 ................(1)
Now the total amount is $50,000
So
x + y = $50,000
y = $50,000 - x ................(2)
Now put the y value in the equation 1
So,
0.13x + 0.03 ($50,000 - x) = $6,000
0.13x + $1,500 - 0.03x = $6,000
0.10x = $6,000 - $1,500
0.10x = $4,500
x = $4,500 ÷ 0.10
= $45,000 at 13%
now y value would be
= $50,000 - $45,000
= $5,000 at 3%

ABCD is a parallelogram.
The coordinates of point A are (2,5)
x = (4,0) and y = (5,12)
Find the coordinates of points B and C.
Answer:
B(6, 5), C(1, -7)
Step-by-step explanation:
A(2, 5)
From A to B, there is translation x, (4, 0).
Add 4 to A's x-coordinate, and add 0 to A's y-coordinate.
B(2 + 4, 5 + 0) = B(6, 5)
From C to B there is the translation y, (5, 12).
Since we are going from B to C, we undo translation y.
The translation from B to C is (-5, -12).
C(6 - 5, 5 - 12) = C(1, -7)

The weights of cockroaches follow a Normal distribution with mean 80 grams and standard deviation 2 grams. Use normal table to answer the question below:
What percent of cockroaches weigh greater than 85 grams?
Answer:
0.621%
Step-by-step explanation:
First of all let's find the z-score which is given by the formula;
z = (x' - μ)/σ
We are given;
Mean; μ = 80 g
Standard deviation; σ = 2 g
Test score; x' = 85 g
Thus;
z = (85 - 80)/2
z = 5/2
z = 2.5
From the z-distribution table attached, at z = 2.5, the probability is:
P(z > 2.5) = 1 - 0.99379 = 0.00621 or 0.621%

Instructions: Match the general form of the function to the name.
We need to match each general form of a function to the name.
• In a linear function, the exponent of the variable x is 1. Thus, it has the general form:
\(y=mx+b\)where m and b are constants.
• In a quadratic function, there is at least one term for which x has exponent 2. Thus, it has the general form:
\(y=ax^2+bx+c\)where a, b, and c are constants, and a ≠ 0.
• In an exponential function, x is the exponent of a constant. Thus, its general form is:
\(y=a(b^x)+c\)where a, b, and c are constants.

transponder for a toll bridge costs $22.50. With the transponder, the toll is $4 each time you cross the bridge. The only other option is toll-by-plate, for which the toll is $5.25 each time you cross the bridge with an additional administrative fee of $1.25 for each crossing. How many times would you need to cross the bridge for the costs of the two toll options to be the same?
You need to cross the bride _ times?
Using linear function you would need to cross the bridge 30 times for the costs of the two toll options to be the same.
What is meant by linear function ?To find out how many times you would need to cross the bridge for the costs of the two toll options to be the same, we need to set up an equation.Let x be the number of times you need to cross the bridge.For the transponder option: 22.50 + 4x = costFor the toll-by-plate option: 5.25x + 1.25x = costSince the costs of the two options need to be equal, we can set the two equations equal to each other and solve for x:22.50 + 4x = 5.25x + 1.25x + 22.504x = 5.25x + 1.25x0.75x = 22.50x = 30So you would need to cross the bridge 30 times for the costs of the two toll options to be the same.To learn more about linear function refer:

The number of times of Puerto Rico is 5/6
No earthquake released 10³ of Colombia
How to determine the number of timesFrom the question, we have the following parameters that can be used in our computation:
The table of values
On the table of values, we have
Colombia = 6.0M
Puerto Rico = 5.0M
This means that
Number of times = Puerto Rico/Colombia
Substitute the known values in the above equation, so, we have the following representation
Number of times = 5/6
The earthquake that released 10³ of ColombiaHere, we have
Colombia = 6.0M
So, we have
Earthquake = Colombia * 10³
This gives
Earthquake = 6 * 10³
From the table of values, we have no entries with the readings 6 * 10³
Hence, no earthquake released 10³ of Colombia

Solve for theta in the image attached below.
Please show full working
Answer:
100°
Step-by-step explanation:
You want the measure of angle θ = ∠BDC in the figure of isosceles triangle ABC with vertex angle A=40° and interior point D such that AD≅BC and ∠BAD = 10°.
Vector solutionWe can define the midpoint of BC as the origin of a coordinate plane, and points B(-1, 0) and C(1, 0). Then point A will be located at A(0, tan(70°)).
Point D will be located at 2∠-100° from A, since AD=BC=2 units, and D is located 10° west of south relative to A.
This locates point D on the coordinate grid.
To find the angle between DC and DB, we can divide vector DC by vector DB. The angle of the quotient is the angle between those vectors. The calculator result in the second attachment shows the angle is 100°, in agreement with the geometry program's result in the first attachment.
θ = 100°
Law of cosines solutionGiven our assignment of a length of 2 to AD and BC, we know the lengths of AC and AB are sec(70°) ≈ 2.9238. This lets us use the law of cosines to find lengths DC and DB:
CD = √(2.9238² +2² -2·2.9238·2·cos(30°)) ≈ 1.5557
DB = √(2.9238² +2² -2·2.9238·2·cos(10°)) ≈ 1.0154
Then the law of cosines can be used again to find θ.
θ = arccos((1.5557² +1.0154² -2²)/(2·1.5557·1.1054))
θ = 100°
Geometrical solutionThe third attachment shows a geometrical solution to finding the angle. We define O as the center of the circle. Angle BAC is an inscribed angle of 40°, so angle BOC will be double that value, 80°.
Locating point G so that AOG is 80° makes segment AG the same length as segments AB and AD. AO bisects angle A, so angle GAD is 10° less than angle GAO, making ∆GAD~∆ACG and locating point D on segment AG. While point D can be shown to lie on segment AG using angle sums, it takes Law of Sines and Law of Cosines relations to demonstrate that point D lies on segment BO, which it does.
The angle of interest, BDC, is an external angle to triangle COD. As such, its measure is the sum of the remote interior angles of that triangle:
∠BDC = 80° +20°
∠BDC = 100°

Find the average rate of change of the function on the interval specified for real number b.
f(x) = 4x2 − 7 on [1, b]
The average rate of change of the function f(x) = 4 · x² - 7 for the interval [1, b] is m = - 4 · (b + 1).
How to derive the average rate of change of a function
Graphically speaking, the average rate of change associated to a function is represented by a secant line formula:
m = [f(b) - f(1)] / (b - 1)
If we know that f(x) = 4 · x² - 7, then the average rate of change is:
m = [4 · b² - 7 - 4 · 1² + 7] / (1 - b)
m = 4 · (b² - 1) / (1 - b)
m = - 4 · (b² - 1) / (b - 1)
m = - 4 · (b + 1)
