A company made a profit of $90,000 in the year 2006. In 2010, the same company made a total profit of $135,000. If the rate of change is a constant, what is the average rate of change of the company’s profit in dollars per year? HELP
Answer:
Average rate of change = $11250 per year.
Step-by-step explanation:
Let's take two points from given information (2006, 90000) and (2010, 135000).
Now, use slope formula to find slope.
Slope =[tex]\frac{y2-y1}{x2-x1}[/tex]
Use the two points to find average rate of change (slope)
Average rate of change =[tex]\frac{135000-90000}{2010-2006}[/tex]
=[tex]\frac{45000}{4}[/tex]
=11250
Average rate of change = $11250 per year.
Find the value of x.
Answer:
6
Step-by-step explanation:
We can find the value x using Euclidian theorem
x^2 = 3*12
x^2 = 36
x = 6
Match each equation with its solution.
Answer:
1. x = -2 , 3
2. x = - 1, 5
3. -1, 6/5
4. - 0/3, 1.3
Step-by-step explanation:
1.
[tex]ln(x+5)=ln(x-1)+ln(x+1)\\\\x+ 5 = (x-1)(x+1)\\\\x + 5 = x^2 - 1\\\\x^2 - x - 6 = 0 \\\\x^2 - 3 x + 2 x - 6 =0 \\\\x(x-3)+2(x-3)=0\\\\x = -2 and 3[/tex]
2.
[tex]e^{x^{2}}=e^{4x +5}\\\\x^2 - 4x - 5 = 0 \\\\x^2 - 5x + x - 5 = 0 \\\\x (x-5)+1 (x-5)=0\\\\x = -1 and 5[/tex]
3.
[tex]log_{4}(5x^2 +2)=log_{4}(x +8)\\\\5x^2 - x - 6 = 0 \\\\5 x^2 - 6 x + 5x- 6 = 0 \\\\5 x (x + 1)-6(x+1)=0\\\\x = -1 and \frac{6}{5}[/tex]
4.
[tex]log(x-1)+log 5x = 2\\\\5 x (x-1) =2 \\\\5x^2 - 5x -2 = 0 \\\\x = \frac{5\pm\sqrt{25+40}}{10}\\\\x = \frac{5\pm 8}{10}\\\\x = 1.3, - 0.3[/tex]
What is the measure of angle x? Please help asap! Khan academy question!
Answer:
38°
Step-by-step explanation:
90-58
I'm unsure if that's right but i think it is. otherwise 180-58 but angle x should be the rest of the angle in KAI
Answer:
[tex]\boxed{\boxed{\tt \angle x=32^{\circ}}}[/tex]
Step-by-step explanation:
From the diagram given, we know that ∠BAC and ∠IAK are vertical angles.
*Vertical angles are two lines that intersect each other.*
So ∠BAC is equal to ∠IAK.
[tex]\tt \overline{KL} \perp \overline{FG}[/tex] so, ∠ABC =90°
(Interior angles in a triangle always add up to 180°).
[tex]\tt \angle BAC+\angle ABC+\angle BCA=180^{\circ}[/tex]
[tex]\tt 58+90+\angle BCA=180^{\circ}[/tex]
[tex]\tt \angle BCA=32^{\circ}[/tex]
∠BCA and ∠x are vertical angles, therefore they are congruent.
∠BCA and ∠x= 32°

What rays are part of line BE?
Answer:
B. ray AB and ray AE
Step-by-step explanation:
Line BE is connected at three points, B, A, and E.
The rays that are part of line BE as shown in the diagram run across these three points. Thus, ray AB connects to Ray AE at point A, to form line BE.
Ray AB and ray AE are therefore parts of line BE.

evaluate and solve: y + 3 = –y + 9
The value of y is 3.
Answer:
Solution given;
: y + 3 = –y + 9
add +y on both term
y+y+3=-y+y+9
subtract both side by 3
2y+3-3=9-3
2y=6
divide both side by 2
2y/2=6/2
y=3
Answer:
y = 3
Step-by-step explanation:
y + 3 = –y + 9
Add y to each side
y+y + 3 = –y +y+ 9
2y +3 = 9
Subtract 3 from each side
2y+3-3 = 9-3
2y = 6
Divide by 2
2y/2 = 6/2
y = 3
The millage rate is the amount of property tax per $1000 of the taxable value of a home. For a certain county the millage rate is 29 mil. A city within the county also imposes a flat fee of $101 per home. a. Write a function representing the total amount of property tax T(x) for a home with a taxable value of x thousand dollars. b. Write an equation for T-1(x). c. What does the inverse function represent in the context of this problem
Answer:
(a) [tex]T(x) = 101 + 0.029 x[/tex]
(b) [tex]T^{-1}(x) = \frac{1000(x - 101)}{29}[/tex]
(c) See explanation
Step-by-step explanation:
[tex]T(x) = 172 + \frac{29}{1000}x[/tex]
Given
[tex]Flat = 101[/tex]
[tex]Rate = 29\ per\ 1000[/tex]
Solving (a): The function for total amount
This is calculated as:
[tex]T(x) = Flat + Rate * x[/tex]
Where:
[tex]x \to[/tex] taxable value
So, we have:
[tex]T(x) = 101 + \frac{29}{1000} * x[/tex]
[tex]T(x) = 101 + 0.029 * x[/tex]
[tex]T(x) = 101 + 0.029 x[/tex]
Solving (b): The inverse function
[tex]T(x) = 101 + 0.029 x[/tex]
Rewrite as:
[tex]y = 101 + 0.029x[/tex]
Swap the variables
[tex]x = 101 + 0.029y[/tex]
Make y the subject
[tex]0.029y = x - 101[/tex]
Divide by 0.029
[tex]y = \frac{x - 101}{0.029}[/tex]
Multiply by 1000/1000
[tex]y = \frac{1000(x - 101)}{29}[/tex]
Replace y with the inverse function
[tex]T^{-1}(x) = \frac{1000(x - 101)}{29}[/tex]
Solving (c): Interpret (b)
The inverse function, in this case; is the taxable value calculated from the amount of property tax

Which is linear
A linear function is represented as any of:
[tex]y = mx + b[/tex]
[tex]y - y_1= m(x - x_1)[/tex]
[tex](a)\ 8x - 3y = 2[/tex]
Rewrite as:
[tex]- 3y = -8x+2[/tex]
Divide by -3
[tex]y = \frac{8}{3}x - \frac{2}{3}[/tex] -- by comparison to [tex]y = mx + b[/tex], this is linear
[tex](b)\ y = |x - 4|-7[/tex]
This is an absolute function. It is not linear
[tex](c)\ y + 8=5(x - 4)[/tex]
By comparison to [tex]y - y_1= m(x - x_1)[/tex], this is linear
[tex](d)\ y = -7[/tex]
by comparison to [tex]y = mx + b[/tex], this is linear because [tex]m= 0[/tex]

Step-by-step explanation:
e^3x+6 =8
Subtract 6 from each side
e^3x+6-6 =8-6
e^3x =2
Take the natural log of each side
ln( e^3x) =ln(2)
3x = ln(2)
divide by 3
3x/3 = 1/3 ln(2)
x = 1/3 ln(2)
x is approximately 0.23104

Answer:
The slope-intercept form is [tex]y=\frac{1}{2}x+\frac{11}{2}[/tex]
Step-by-step explanation:
To find the slope, use
[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
Replace the x and y values with the points.
[tex]m=\frac{7-5}{3-(-1)}[/tex]
Solve.
[tex]m=\frac{2}{4}[/tex]
[tex]m=\frac{1}{2}[/tex]
After that, find the y-intercept form.
Put the equation in point-slope form.
[tex]y-5=\frac{1}{2}(x+1)[/tex]
Replace x with 0.
[tex]y-5=\frac{1}{2}(0+1)[/tex]
[tex]y-5=\frac{1}{2}[/tex]
Add 5 to both sides.
[tex]y=5\frac{1}{2}[/tex]
Convert to improper fraction form.
The y-intercept is [tex]\frac{11}{2}[/tex]
Now finally, write in slope-intercept form. (y=mx+b)
m is slope, b is the y-intercept.

Find the missing side or angle.
Round to the nearest tenth.
b=3
a=9
c=11
C= ?
Answer:
C=125°
Step-by-step explanation:
Hi there!
To find angle C, we can use the cosine law:
[tex]cosC=\frac{a^2+b^2-c^2}{2ab}[/tex]
Plug in the given information
[tex]cosC=\frac{9^2+3^2-11^2}{2(9)(3)}[/tex]
[tex]cosC=\frac{-31}{54}[/tex]
[tex]C=cos^-^1(\frac{-31}{54})[/tex]
[tex]C=cos^-^1(\frac{-31}{54})\\C=125[/tex]
Therefore, angle C is approximately 125 degrees.

Please help me pls help with step by step on paper and send it to me pls ! Thank you
Answer:
6
Step-by-step explanation:
So since we are handling decimals we need to get rid of them in order to divide.
Now the numbers should be 96 and 16.
16 * 6 = 96 therefore 6 is the answer.
The required solution of 9.6 divided by 1.6 is 6.
Given that,
To determine 9.6 divided by 1.6
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
= 9.6 / 1.6
= 96 * 10 / 16 / 10
Factoring 36 in the numerator as 96 = 16 * 6
= 16 * 6 * 10 / 16 * 10
Now,
factors that are common between numerator and denominator will be eliminated,
= 6 / 1
= 6
Thus, the required solution of 9.6 divided by 1.6 is 6.
