What is the inverse 7,3?Use a symbol to show this. How much is its value?
Answers
The inverse of 7.3 is 1/7.3, which is approximately equal to 0.13699. This means that if we multiply 7.3 by 0.13699, we should get a value close to 1.
The inverse of a number is the reciprocal or multiplicative inverse of that number. In other words, it is a number that when multiplied by the original number gives 1. To find the inverse of a number, we can simply divide 1 by that number.
In this case, we are asked to find the inverse of 7.3. So we can write:
inverse of 7.3 = 1/7.3
This means that if we multiply 7.3 by its inverse, we should get 1 as the result:
7.3 * (1/7.3) = 1
Therefore, the inverse of 7.3 is 1/7.3, which is approximately equal to 0.13699. This means that if we multiply 7.3 by 0.13699, we should get a value close to 1.
As an example, let's multiply 7.3 by its inverse and see what we get:
7.3 * 0.13699 = 0.9999...
We can see that the result is very close to 1, which confirms that 0.13699 is indeed the inverse of 7.3.

Answers
Solution:
Given:
\(\begin{gathered} \text{The sequence;} \\ 3,8,13,18,23,\ldots \end{gathered}\)The sequence given is an arithmetic progression because it increases by a common difference.
Hence, the function rule for the sequence will follow that of an arithmetic progression (A.P).
The nth term of an A.P is given by;
\(\begin{gathered} a_n=a+(n-1)d_{} \\ \text{where;} \\ a_n\text{ is the nth term} \\ a\text{ is the first term} \\ n\text{ is the number of terms} \\ d\text{ is the co}mmon\text{ difference} \end{gathered}\)For the sequence given;
\(\begin{gathered} 3,8,13,18,23,\ldots \\ \\ a=3 \\ d=8-3\text{ or 13-8 or 18-13 or 23-18} \\ d=5 \\ \\ \text{Hence, substituting these values into the nth term of an A.P to get the rule,} \\ a_n=a+(n-1)d_{} \\ A(n)=3+(n-1)(5) \end{gathered}\)Therefore, the function rule for the sequence is;
\(A(n)=3+(n-1)(5)\)The compound interest formula states the if P dollars are invested at an annual interest rate of r, compounded n times per year, then A, the amount of money present after t years, is given by A=P(1+r/n)^nt. If $9500 is invested at 7% compounded quarterly, how much will this investment be worth in 14 years? Solve the problem and round answer to two decimal places.
Answers
The investment of $9500 at an annual interest rate of 7% compounded quarterly will be worth approximately $24,843.34 after 14 years.
Using the compound interest formula, we have P = $9500, r = 7% = 0.07, n = 4 (quarterly compounding), and t = 14 years. Substituting these values into the formula, we can calculate the final amount A:
A = $9500 * (1 + 0.07/4)^(4*14)
≈ $9500 * (1.0175)^(56)
≈ $9500 * 2.6186418
≈ $24,843.34
Therefore, the investment will be worth approximately $24,843.34 after 14 years.

What are similar triangles?
If two triangles have the same ratio of corresponding sides and an equal pair of corresponding angles, they are similar. When two or more figures have the same shape but differ in size, they are referred to as similar figures.
Consider △ABC:
Height = AC = x, Hypoteneous = BC = 4+8 = 12.
Consider △ADC:
Height = DC = 8, Base = AD = y, Hypoteneous = AC = x
Consider △ABD:
Height = AD = y, Base = 4.
The triangle ABC is similar to ADC, and ABC is similar to ABD. Since all have one right angle and one angle is common.
The ratio of the corresponding sides of similar triangles is constant.
Consider △ABC and △ADC:
AC/DC = BC/AC
x/8 = 12/x
x² = 12×8
x = 4√6.
Since ABC is similar to ADC and ABC is similar to ABD. Then ADC is similar to ABD.

Enter your answer using slope-intercept form.
Answers
The equation of line is y = -5x using the given passing coordinates (-8, 8).
Given: The coordinates of the point through which the line passes are (-8, 8), and the line is parallel to the line
y = -5x + 5.
The standard form of a linear equation is given by the formula:
Ax + By = C
where A, B, and C are constants. We will use this formula to find the equation of the line through the point (-8, 8).
The line parallel to y = -5x + 5 will have the same slope as this line since parallel lines have the same slope.
Hence, the slope of the line we are looking for is -5.
The point (-8, 8) lies on the line we are looking for.
Therefore, we can substitute x = -8 and y = 8 into the equation of the line to get:
-5(-8) + b = 88 + b
= 8b
= 8 - 8b
= 0
So, the equation of the line is y = -5x.

Emir is standing in a treehouse and looking down at a swingset in the yard next door. The angle of depression from Emir's eyeline to the swingset is 30.26° and Emir is 14 feet from the ground How many feet is the base of the treehouse from swingset? Round your answer to the nearest foot
ANSWERS:
15 feet
20 feet
18 feet
24 feet
Answers
=============================================
Explanation:
Refer to the diagram below. The goal is to find x, which is the horizontal distance from the base of the tree to the swing set.
Focus on triangle BCD.
The angle B is roughly 30.26 degrees, and this is the angle of depression. This is the amount of degrees Emir must look down (when starting at the horizontal) to spot the swing set.
We know that he's 14 ft off the ground, which explains why AB = CD = 14.
The goal is to find BC = AD = x.
---------------------------
Again, keep your focus on triangle BCD.
We'll use the tangent ratio to say
tan(angle) = opposite/adjacent
tan(B) = CD/BC
tan(30.26) = 14/x
x*tan(30.26) = 14
x = 14/tan(30.26)
x = 23.9965714046732
That value is approximate. Make sure your calculator is in degree mode.
That value rounds to 24 feet when rounding to the nearest whole foot.
Using the slope concept, it is found that the base of the treehouse is 24 feet from swingset.
What is a slope? The slope is given by the vertical change divided by the horizontal change. It's also the tangent of the angle of depression.
In this problem:
The vertical distance is of 14 feet.The horizontal distance is of x feet.The angle of depression is of 30.26º.Hence:
\(\tan{30.26^{\circ}} = \frac{14}{x}\)
\(0.5834 = \frac{14}{x}\)
\(x = \frac{14}{0.5834}\)
\(x = 24\)
The base of the treehouse is 24 feet from swingset.

(A) If 100 frames are produced, the average cost is $ per frame. (B) The marginal average cost at a production level of 100 units is $ per frame. (Round to the nearest cent as needed.) (C) Using the results from parts (A) and (B), the estimate of the average cost per frame if 101 frames are produced is $ (Round to the nearest cent as needed.)
Answers
A. The average cost per frame if 100 frames are produced is $1,300.
B. The marginal average cost is $900 per frame.
C. The estimated average cost per frame if 101 frames are produced is $2,200.
(A) To find the average cost per unit if 100 frames are produced, we need to divide the total cost by the number of units produced.
C(x) = 40,000 + 900x
C(100) = 40,000 + 900(100)
C(100) = 130,000
The total cost of producing 100 frames is $130,000.
To find the average cost per frame, we divide the total cost by the number of frames produced:
Average Cost = Total Cost / Number of Frames
Average Cost = $130,000 / 100
Average Cost = $1,300
Therefore, the average cost per frame if 100 frames are produced is $1,300.
(B) To find the marginal average cost at a production level of 100 units, we need to find the derivative of the cost function:
C(x) = 40,000 + 900x
C'(x) = 900
The marginal average cost is the derivative of the cost function, so at a production level of 100 units, the marginal average cost is $900 per frame.
(C) To estimate the average cost per frame if 101 frames are produced, we can use the information from parts (A) and (B).
If the average cost per frame for 100 frames is $1,300, and the marginal average cost at 100 frames is $900, we can estimate the average cost per frame for 101 frames using the formula:
Average Cost = Previous Average Cost + Marginal Average Cost
Average Cost = $1,300 + $900
Average Cost = $2,200
Therefore, the estimated average cost per frame if 101 frames are produced is $2,200.

If the region enclosed by the -axis, the line y = 2 , and the curve y = โx is revolved about the -axis, the volume of the solid generated is
Answers
The volume of the solid generated by revolving the triangle about the -axis is (8π/3).
The region enclosed by the -axis, the line y = 2, and the curve y = -x is a triangle with base 2 and height 2.
To find the volume of the solid generated by revolving this triangle about the -axis, we can use the method of cylindrical shells.
The volume of each shell is given by the formula:
V = 2πr * h * δr
where r is the distance from the -axis to the shell, h is the height of the shell, and δr is the thickness of the shell.
We can express r as a function of y, since each shell corresponds to a vertical slice of the triangle:
r = y
The height of each shell is given by the difference between the -axis and the curve y = -x:
h = 2 - (-x) = 2 + x
Finally, the thickness of each shell is δr = dy.
Therefore, the volume of the solid is:
V = ∫[0,2] 2πy * (2 + y) dy
= 2π ∫[0,2] (2y + y^2) dy
= 2π [y^2 + (1/3)y^3] |[0,2]
= (8π/3)

If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c. True False Question 4 (1 point). A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0. True False Question 5 (1 point) If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = C. True False
Answers
Question 3: True
Question 4: False
Question 5: True
If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c.
This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.
Question 3: If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c.
True
When the derivative of a function, f'(x), is negative at a point c, it indicates that the function is decreasing at that point. Additionally, if the second derivative, f''(x), exists and is negative at x = c, it implies that the graph of f(x) is concave down at that point.
Question 4: A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0.
False
A local extreme point of a polynomial function can occur when f'(x) = 0, but it is not the only condition. A local extreme point can also occur when f'(x) does not exist (such as at a sharp corner or cusp) or when f'(x) is undefined. Therefore, f'(x) being equal to zero is not the sole requirement for a local extreme point to exist.
Question 5: If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = c.
True
If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c. This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

Solve the equation on the interval [0,2π), showing all steps of the solution process. While you are welcome to check with a solver, no credit will be given for magic answers! If it is possible to obtain an exact value solution, you must give in that form. Otherwise, use decimal radians rounded to two places for the angles. Clearly indicate reference angles and quadrants. After solving, produce a Desmos graph showing the left and right sides of the equation graphed as functions, restricted to [0,2π), and click to reveal points of intersection. Screenshot and include. Solve: 2 sin^2 x + 20 cos x = 6
Answers
The equation are: x = -1 radians (-57.3°) and x = 11 radians (626.9°).
To solve this equation, use the identity sin2x + cos2x = 1 and apply it to the left side of the equation.
2 sin2x + 20 cos x = 6
2 (1 - cos2x) + 20 cos x = 6
2 - 2 cos2x + 20 cos x = 6
2 cos2x - 20 cos x + 2 = 6
cos2x - 10 cos x + 1 = 0
Next, solve the resulting quadratic equation using the quadratic formula: x = [-b ± √(b2 - 4ac)]/2a. In this case:
x = [-(-10) ± √((-10)2 - 4(1)(1))]/2(1)
x = [10 ± √(100 - 4)]/2
x = [10 ± √(96)]/2
x = (10 ± 4√6)/2
x = (10 ± 12)/2
x = 5 ± 6
We then use the interval [0,2π) to calculate the exact radian values for x. The two solutions in this interval are:
x = 5 - 6 = -1
x = 5 + 6 = 11
For reference, the angle corresponding to -1 radians is -57.3° and the angle corresponding to 11 radians is 626.9°.
To check the solution, graph the two sides of the equation on Desmos, with the interval [0,2π). The graph will show the two points of intersection (marked with circles) which correspond to the two solutions.
In conclusion, the exact values of x which satisfy the equation are: x = -1 radians (-57.3°) and x = 11 radians (626.9°).
