Question B.) ????
Answer:
b) [tex]f^{-1}(x) = \frac{4x+5}{3}[/tex]
Step-by-step explanation:
b) To find the inverse function, switch the [tex]x[/tex] and [tex]y[/tex] variables and solve for [tex]y[/tex]:
[tex]f(x) = \frac{3x-5}{4}\\y = \frac{3x-5}{4}\\x = \frac{3y-5}{4}\\4x = 3y-5\\4x+5 = 3y\\\frac{4x+5}{3} = y\\f^{-1}(x) = \frac{4x+5}{3}[/tex]
Verify Answer:
[tex]f(1) = \frac{3(1)-5}{4} = -0.5\\f^{-1}(-0.5) = \frac{4(-0.5)+5}{3} = 1[/tex]

One winter day, the temperature at noon was -9f The temperature then rose by 1/2 degree each hour for 3 hours before dropping by 2 1/4 degrees each hour for 2 hours. What was the temperature, in degrees Fahrenheit, at 5 PM?
Answer:
The temperature at 5 PM was - 12°FStep-by-step explanation:
One winter day, the temperature at noon was -9°F.
The temperature then rose by 1/2 degree each hour for 3 hours:
1/2 × 3 = 3/2 = 1 1/2The temperature then dropped by 2 1/4 degrees each hour for 2 hours:
- 2 1/4 × 2 = - 4 2/4 = - 4 1/2Now add up all three values to find the final value:
- 9 + 1 1/2 - 4 1/2 = - 9 + 1 - 4 = - 12Find the median and mean of the data set below:
3,40,15,28
3,40,15,28
Answer:
21.5
Step-by-step explanation:
Median: List all numbers in order, then find the two in the middle and average them so 3 15 28 40 and then do 15+28=43 then divide by 2 = 21.5
Mean: Average all of them so 3+15+28+40=86 divided by 4 = 21.5

Find the volume of a cone with the base of 10 and height of 6
Answer:
Answer = 157
Step-by-step explanation:
The formula to finding the volume of a cone is h(pi)(r^2)/3. We know that the height is 6 and the base is 10. This means that the radius is 5 because it is 1/2 of the base. Now we plug in our numbers into the equation and get 157!
Hope that helps! :)

What is the point-slope form of a line with slope -5 that contains the point
a
(2,-1)?
The point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).
What is point slope form?The point slope form of a line is the expression of line which has a specified slope and passes through a point.
The point slope form is givne as,
(y-y₁)=m(x-x₁)
Here, m is the slope of the line, x₁ is the x coordinate of the point by which line passes and y₁ is the y coordinate of the same point.
The slope of a line is -5. This line contains the point A (2,-1). Thus, the point slope form is,
(y-y₁)=m(x-x₁)
(y-(-1))=-5(x-2)
(y+1)=-5(x-2)
Thus, the point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

Area of Trapezoid :
1/2 x (a + b) x ha and b = parallel side lengthsh = heightSolving :
1/2 x (5.2 + 3.6) x 3.11/2 x 8.8 x 3.14.4 x 3.113.64 cm²Answer:
13.64 square centimeters
Step-by-step explanation:
Hey there!
The formula to finding the area of a trapezoid is:
1/2 (p + q) h
Where h is the height, p is the shorter base and q is the longer base
In this case
p - 3.6
q - 5.2
h - 3.1
1/2 (3.6 + 5.2) 3.1
1/2 (8.8) 3.1
(4.4) 3.1 --> 4.4 x 3.1
13.64
So, the area of this trapezoid is 13.64 square centimeters

How do I find the domain range and function of the graph
Answer:
D = {-3, -2, -1, 1, 4}
R = {-5, -1, 0, 2}
Step-by-step explanation:
You have correctly described the process of finding the domain and range by the way you filled in the blanks at the top of the sheet.
__
The domain is the set of x-values of the points on the graph:
D = {-3, -2, -1, 1, 4}
The range is the set of (unique) y-values of the points on the graph:
R = {-5, -1, 0, 2}

A culture of bacteria contains 1,500 bacteria initially and doubles every 30 minutes.
1. Write a function that models the number of bacteria after t time.
2. Find the number of bacteria after 2 hours.
3. After how many minutes will there be 12,000 bacteria
if the bacterial is doubling, that means the growth rate is 100%, or 100% plus whatever it was before, so
[tex]\textit{Periodic/Cyclical Exponential Growth} \\\\ A=P(1 + r)^{\frac{t}{c}}\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &1500\\ r=rate\to 100\%\to \frac{100}{100}\dotfill &1\\ t=minutes\\ c=period\dotfill &30 \end{cases} \\\\\\ A=1500(1 + 1)^{\frac{t}{30}}\implies A=1500(2)^{\frac{t}{30}} \\\\\\ \stackrel{\textit{after two hours, or 120 minutes, t = 120}~\hfill }{A=1500(2)^{\frac{120}{30}}\implies A=1500(2)^4\implies A=24000}[/tex]

Solve the equation for x. Do not include "x =" in your answer.
-3+√3x-11=5
Help pls
The value of x in the equation is 25
How to solve for x?The equation is given as;
[tex]-3 + \sqrt{3x - 11} = 5[/tex]
Add 3 to both sides
[tex]\sqrt{3x - 11} = 8[/tex]
Take the square of both sides
3x- 11 = 64
Add 11 to both sides
3x = 75
Divide both sides by 3
x = 25
Hence, the value of x in the equation is 25
