What is (f+g)(x)?
f(x)=4x+6
g(x)= -5x
Write your answer as a polynomial or a rational function in simplest form.
Answer:
(f + g)(x)= -x + 6.
Step-by-step explanation:
The sum of two functions, f(x) and g(x), is given by (f + g)(x) = f(x) + g(x).
So, for f(x) = 4x + 6 and g(x) = -5x,
(f + g)(x) = f(x) + g(x) = (4x + 6) + (-5x) = -x + 6.
The result is a linear function and is already in the simplest form, so it cannot be further simplified.

5. A cliff-jumper of mass 68.0 kg stands on the edge of a cliff and possesses 16,800 J of potential energy. How high up is this lunatic from the base of the cliff?
The potential energy of an object is given by the equation:
PE = mgh
where PE is potential energy, m is mass, g is the acceleration due to gravity, and h is the height.
Rearranging this equation, we get:
h = PE / (mg)
Substituting the given values, we get:
h = 16800 J / (68.0 kg x 9.81 m/s^2)
h = 24.8 meters
Therefore, the cliff-jumper is standing 24.8 meters above the base of the cliff.

In the diagram KG, JF, AE and AH intersect at point A. Use this diagram for problems 1-3.
1. Describe the relevant angle relationships in the diagram.
2. Write and solve an equation to find the value of x
3. What are the measures if
As a result, the measurements of angles KAG and JAF are both 90, and the measure of arc KG is 2 * 90 = 180. Angle HAE and angle HAF are both 90 degrees.
What is angle?An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles.
Here,
In the diagram, since KG, JF, AE, and AH intersect at point A, we know that angle KAG = angle JAF (both are inscribed angles and intercept the same arc), and angle HAE = angle HAF (both are alternate interior angles and are equal in measure).
To find the value of x, we need to use the angle relationships. Since angle KAG = angle JAF, and they are both inscribed angles, they are equal to half the measure of the intercepted arc KG. We also know that angle HAE = angle HAF, so we can use them to find the measure of KG.
Let's call the measure of KG = 2x. Then, angle KAG = angle JAF = x, and angle HAE = angle HAF = x.
Adding the measures of angle KAG and angle HAE, we get x + x = 2x = 180. Solving for x, we get x = 90.
So, the measures of angle KAG and angle JAF are 90, and the measure of arc KG is 2 * 90 = 180. The measures of angle HAE and angle HAF are also 90.

Kweku drives about 18,000 miles a year. How much would he save in a year buying electricity for the Desla electric compared to buying gas for the deswagon? and about how long would it take to makeup for the higher sale price of the desla electric?
Kweku would save $180 in a year buying electricity for the Desla electric compared to buying gas for the Deswagon.
To make up for the higher sale price,
it will take him more than 66 years.
What is subtraction?Subtraction is a mathematical operation. Which is used to remove terms or objects in the expression.
Given:
Deselectric costs $11900 more than the Deswagon.
Unit cost:
Deselectric: $0.11 per mile.
Deswagon: $0.12 per mile.
Kweku drives about 18,000 miles a year.

In kite PQRS, measure of angle QPO=50° and measure of angle QRO=70°. Find measure of angle PSR
The measure of angle PSR in a kite PQRS, is equals to the 60°.
We have a kite PQRS, present in above figure. The measure of angle QPO = 50°
The measure of angle QRO = 70°
We have to determine the measure of angle PSR. As we see in figure, there is four right angled triangles as ∆POQ, ∆OQR , ∆POS and ∆OSR.
measure of angle POS = measure of angle SOR = 90°
measure of angle SPO = measure of angle QRO = 70° ( Since alternative angles)
Similarly, measure of angle SRO
= measure of angle QPO = 50° ( Alternative angles )
So, measure of angle PSR = measure of angle PSO + measure of angle RSO --(1)
Measure of angle RSO = 180° - measure of angle ROS - measure of angle SRO
= 180° - 90° - 50° = 40°
Also, Measure of angle PSO = 180° - measure of angle POS - measure of angle SPO = 180° - 90° - 70° = 20°
So, from equation (1),
measure of angle PSR = measure of angle PSO + measure of angle RSO
= 40° + 20°
= 60°
Hence, required measure of angle is 60°.

appeared on the statement but had not been recorded
in the register. You also find that Check 307 for $35.29
had been entered in the register as $32.95. Reconcile the
checking account.
The new check register balance of $131.35 now matches the bank statement balance of $161.96.
Describe bank balance.A bank balance is the amount of money a person or organization has in their account at a financial institution such as a bank. It reflects the amount of money that is available for spending or withdrawal, taking into account any transactions that have been made or are pending. The bank balance is an important aspect of managing finances, and individuals and businesses monitor their balances regularly to ensure that they have enough money to cover their expenses and to make sure that their accounts are in good standing.
To reconcile the checking account, you need to find out the reason for the difference between the check register balance ($107.87) and the bank statement balance ($161.96).
Add the interest earned of $0.43 to the check register balance: $107.87 + $0.43 = $108.30
Add the ATM deposit of $56 to the check register balance: $108.30 + $56 = $164.30
Subtract the incorrect amount of Check 307 ($32.95 instead of $35.29) from the check register balance: $164.30 - $32.95 = $131.35
The new check register balance of $131.35 now matches the bank statement balance of $161.96. This means the checking account has been reconciled.

this boxplot shows the distribution of ages for a class of 20 students. why is there no line in the box to indicate the median age?
If there is no line in the box to indicate the median, it is possible that the median has not been calculated or that the data set is too small to provide an accurate representation of the median.
A boxplot is a visual representation of the distribution of a set of data, and it typically consists of a box, two whiskers, and possibly some outliers. The box represents the interquartile range (IQR), which is the range between the first and third quartiles of the data. The median (or second quartile) is usually represented by a line within the box.
If there is no line in the box to indicate the median, it is possible that the median has not been calculated or that the data set is too small to provide an accurate representation of the median. With only 20 students, it is possible that the median may not be a meaningful representation of the central tendency of the data, especially if there are extreme outliers or skewed distributions. In such cases, it is best to consult other measures of central tendency, such as the mean or mode, to get a better understanding of the data.

4. Anthony wanted to make his own soup can label. The soup can is shaped like a cylinder.
The can has a diameter of 16 cm and a height of 8 cm. About how much paper did he
used to create the label (lateral)? (If necessary, use T = 3. 14 )
The amount of paper used to create the label was approximately 201.06 cm². This was calculated by multiplying the diameter of 16 cm by the height of 8 cm and then multiplying the result by 3.14 (T).
The amount of paper used to create the label for an 8 cm tall cylinder can with a diameter of 16 cm can be calculated by using the formula for the lateral surface area of a cylinder (T*r*h). T is the constant pi, which is equal to 3.14. r is the radius of the cylinder, which is equal to half of the diameter (16 cm/2 = 8 cm). h is the height of the cylinder, 8 cm. Therefore, the lateral surface area of the cylinder can is calculated by multiplying 3.14 by 8 cm (radius) by 8 cm (height). This results in 201.06 cm² of paper needed to create the label. The label can be wrapped around the cylinder, covering the whole surface area of the can.

In the years from 2010 to 2015, the population of the District of Columbia is expected to decrease about 0.9% annually. In 2010, the population was about 530,000. What is the population of the District of Columbia expected to be in 2015?
Answer: 506,150
First we must divided 0.9 into 530,000 to find out how much of the population will decrease each year.
0.9% of 530,000 is 4770. Which means that each year, 4,770 people will move the District of Columbia. From 2010 to 2015, that is 5 years, which means that we have to multiply 4,770 by 5.
4770 x 5 is 23850.
Next we have to subtract the amount of people who moved.
530,000- 23,850 is 506,150
This means by 2015, the expected population will be 506,150 in the District of Columbia.

A bag contains red and blue counters in the ratio 3:5. There are 90 red counters in the bag. What is the total number of counters in the bag?
Answer:
The total number of counters in the bag is 150.
Step-by-step explanation:
There are 90 red counters and the ratio of red to blue is 3:5, which means that for every 3 red counters there are 5 blue counters. Thus, 90 red counters would mean that there are 5/3 times as many blue counters, or 150/3 = 50 blue counters. Therefore, 90 red counters + 50 blue counters = 150 counters in total.
five cards are dealt without replacement from this deck. what is the probability that at least two of the four cards dealt have the same numeric value (1 through 20)?
The probability that at least two of the four cards dealt have the same numeric value (1 through 20) is approximately 0.907.
To calculate the exact probability, we need to consider the different ways that two or more cards could have the same numeric value. If two cards have the same numeric value, there are 19 ways to choose that value and 2 ways to choose the two cards with that value. The probability of this happening is 19 * (2 / 20 * 19 / 19) * (18 / 18 * 17 / 18) * (16 / 17 * 16 / 17) * (15 / 16 * 15 / 16) = 19 * (1/190) = 0.1.
Similarly, we can calculate the probability of three or four cards having the same numeric value. Adding these probabilities, we get an estimate of 0.907 for the probability that at least two of the four cards dealt have the same numeric value.
