For f(x)=2x+1 and g(x)=x+14 , find (g o f) (x).
Answers
Answer:
(g o f) (x) = 2x + 16
Step-by-step explanation:
" (g o f) (x) )" is called "the composition of f and g."
Evaluating this involves substituting the function f(x) = 2x + 1 for x in g(x) = x+14:
(g o f) (x) = 2(x+1) + 14, or
(g o f) (x) = 2x + 2 + 14, or

4400 dollars is placed ina an account with an annual interest rate of %8.25. How much will be in the account after 29 years
Answers
Answer: 43839.13
Step-by-step explanation:
Final answer:
To calculate the amount in the account after 29 years, use the formula for compound interest. The amount in the account will be approximately $40,882.53.
Explanation:
To calculate the amount in the account after 29 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal (initial amount), r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year, and t is the number of years. In this case, the principal is $4400, the annual interest rate is 8.25%, and since it is not specified, we'll assume interest is compounded annually. So, the formula becomes:
A = 4400(1 + 0.0825/1)^(1*29)
To calculate this, we can enter the expression into a calculator or spreadsheet:
A = 4400(1 + 0.0825)^(29)
After evaluating this expression, we find that the amount in the account after 29 years will be approximately $40,882.53.

What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is a television production company charges a basic fee of $4000 and then $2000 per hour when filming a commercial.
Assume that the number of hours required for filming the commercial be [h]. Then, we can write, the equation as follows -
y[h] = 2000h + 4000
The graph of the equation is attached with the answer.
For 4 hours of filming, the production cost would be -
y[4] = 2000 x 4 + 4000 = 8000 + 4000 = 12000
Therefore, the equation in slope - intercept form is as - y[h] = 2000h + 4000 and for 4 hours of filming, the production cost would be $12000.

What is the slope of a line?A slope of a line is the change in y coordinate with respect to the change in x coordinate.
How to find the slope of line from the two points?If [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} , y_{2} )[/tex] be the two points then the slope of the line is given by
[tex]slope = \frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]
According to the given question.
We have slope of a line is [tex]\frac{-3}{5}[/tex].
As, we know that the two parallel lines have the same slope.
Now according to the given ordered pairs
A). (-8, 8) and (2, 2)
[tex]slope = \frac{2-8}{2+8} = \frac{-6}{10} =\frac{-3}{5}[/tex]
Therefore, (-8, 8) and (2, 2) are the ordered pairs could be the points on the parallel line.
B) (-5, -1) and (0, 2)
[tex]slope = \frac{2+1}{0+5} =\frac{3}{5} \neq \frac{-3}{5}[/tex]
Hence, the ordered pair (-5, -1) and (0, 2) will never be the points on the parallel line.
C) (-3, 6) and (6, -9)
[tex]slope = \frac{-9-6}{6+3} =\frac{-15}{9} =\frac{-5}{3}\neq \frac{-3}{5}[/tex]
The ordered pair (-3, 6) and (6, -9) will never be the points on the parallel line.
D). (-2, 1) and (3, -2)
[tex]slope = \frac{-2-1}{3+2} =\frac{-3}{5}[/tex]
Therefore, (-2, 1) and (3, -2) are the ordered pairs could be the points on the parallel line.
E). (0, 2) and (5, 5)
[tex]slope = \frac{5-2}{5-0} =\frac{3}{5} \neq \frac{-3}{5}[/tex]
Therefore, (0, 2) and (5, 5) are the ordered pairs could not be the points on the parallel line.

To determine if the given ordered pairs could be points on a parallel line with a slope of -3/5, we can calculate the slope of each line and compare it to the original slope. The pairs (D) (-2, 1) and (3, -2) have a slope of -3/5, making them parallel.
Explanation:A line with a slope of -3/5 is a line that slopes downwards from left to right. In order for a line to be parallel to this line, it must have the same slope. To determine if the given ordered pairs could be points on a parallel line, we can calculate the slope of each line and compare it to the slope of the original line.
B) (-5, -1) and (0, 2): The slope of this line is (2 - (-1))/(0 - (-5)) = 3/5, which is different from the original slope of -3/5. Therefore, this line is not parallel.
D) (-2, 1) and (3, -2): The slope of this line is (-2-(-2))/(3-(-2)) = -3/5, which is equal to the original slope of -3/5. Therefore, this line is parallel.
E) (0, 2) and (5, 5): The slope of this line is (5 - 2)/(5 - 0) = 3/5, which is different from the original slope of -3/5. Therefore, this line is not parallel.
So, the parallel lines are (D) (-2, 1) and (3, -2).

Jason's current yearly income is $13,000...If Jason’s training will allow him to get a job making $34,000 a year, how long will it take him to recover his initial investment of $35,200?
Answers
First, find the amount of extra money that he will make.
34,000 - 13,000 = 21,000
He will be making an extra 21,000 per year.
Now, divide the cost of his training by the amount of his increase.
35200 / 21000 = 1.68
That gives you the amount of years it will take him to pay off his investment.

Answers
If you draw a picture of the problem, you will see that you have to solve two right triangle problems with the tangent ratio.
If we subtract the measurements of the two triangles, we will have only the length of the radio tower.
tan(48) = x / 63
x = 69.97
tan(38) = x / 63
x = 49.22
69.97 - 49.22 = 20.77 for the height of the radio tower

(x^-2y^-4x³)^-2
We can combine the x terms inside the brackets using the concept;
x ^a × x^b = x^(a+b)
Therefore,
(x^-2)(x^3) = x^(3-2) = x^!
Thus we get;
(xy^-4)^-2
Using the concept
(x^a)^b = x^(ab)
Therefore
= x ^(-2×1) y^(-2×-4)
=x^-2y^8
But using the concept; x^-a = 1/x^a
Thus, x^-2y^8 = y^8/x²
Hence the simplified equation is;

ABC is an isosceles right triangle in which AB has a slope of -1 and angle ABC = 90 degrees. Triangle ABC is dilated by a scale factor of 1.8 with the origin as the center of dilation, resulting in the image A'B'C'. What is the slope of B'C'?
Answers
This kind of transformation results in a similar figure.
So the triangle A'B'C' will be similar to triangle ABC: which means that all the angles are preserved (thy are congruent).
Being the angles congruent the slope of B'C' will be the same angle of BC.
Since, the slope of AB is - 1, the other two sopes are one 0 and the other undefined (∞). The horizontal side has slope 0 and the vertical side has slope ∞.
Since you did not attache any figure I do not know whether B'C' is the horizontal or the vertical side.
The answer is that the slope of B'C' is zero if it is the horizontal side, and the slope is ∞ if B'C' is the vertical side.

Slope of 1

Final answer:
The circumference of the lid is approximately 132 millimeters, Thus, option D is correct.
Explanation:
To find the circumference [tex](\( C \))[/tex] of the lid, we use the formula for the circumference of a circle:
[tex]\[ C = \pi \times d \][/tex]
Where [tex]\( d \)[/tex] is the diameter of the circle.
Given that the diameter (\( d \)) of the lid is 42 millimeters and using the value of [tex]\( \pi \)[/tex] as [tex]\( \frac{22}{7} \)[/tex], we can calculate the circumference as follows:
[tex]\[ C = \frac{22}{7} \times 42 \][/tex]
[tex]\[ C = \frac{22 \times 42}{7} \][/tex]
[tex]\[ C = \frac{924}{7} \][/tex]
[tex]\[ C \approx 132 \, \text{mm} \][/tex]
Therefore, the circumference of the lid is approximately 132 millimeters, which corresponds to option D.

Step-by-step explanation:
We are given that,
Original amount of deodorant in the bottle = 30 grams
The rate of evaporation = 12% = 0.12
That is, we see that the deodorant is decreasing as the number of days increases.
So, the function form of the decrease in the amount of deodorant is given by,
[tex]f(x)=30(1-0.12)^x[/tex], where x is the number of days.
i.e. [tex]f(x)=30(0.88)^x[/tex], where x is the number of days.
Hence, the graph representing the amount of deodorant after x number of days is,

Determine if the properties define a Ray or a line segment
Answers
a line segment has 2 endpoints and a defined measure
A ray in geometric optics represents the path of light as a straight line originating from a point, while a line segment is a part of a line with two endpoints and a measurable length. The properties mentioned can be used to determine if they define a ray or a line segment.
Explanation:A ray in geometric optics is a straight line that originates at some point. In the context of light, a ray represents the path of light as it travels. When light encounters objects or changes media, it may change direction but it continues to travel in a straight line or as a ray. We can think of a ray of light as a straight line or a laser ray.
A line segment, on the other hand, is a part of a line with two endpoints. It has a definite length and can be measured. In the context of light, a line segment would indicate a finite path of light.
Given the properties mentioned, we can determine if they define a ray or a line segment. If the properties describe a straight line with no defined endpoints, it is a ray. If the properties suggest a line with two endpoints and a measurable length, it is a line segment.
