Solving the inequality we get x>-9.33
The graph is shown in figure attached.
Step-by-step explanation:
We need to solve the inequality: [tex]34 > 3(2-x)[/tex]
Solving:
[tex]34 > 3(2-x)\\[/tex]
Switching the sides , reversing the inequality and Multiply 3 with terms inside the bracket
[tex]3(2-x)<34\\6-3x<34[/tex]
Subtract 6 from both sides
[tex]6-3x-6<34-6\\-3x<28[/tex]
Divide both sides by -3 and inequality will be reversed
[tex]\frac{-3x}{-3} >\frac{-28}{3} \\x>\frac{-28}{3}\\x>-9.33[/tex]
Solving the inequality we get x>-9.33

The graph shows the distance Arlene ran on Saturday preparing for a marathon. What is the rate of change and what does it represent?
Answer:
Rate of change = 6 miles per hour
Step-by-step explanation:
Rate of change of the line is represented by the slope of the line.
Formula to get the rate of change is,
m = [tex]\frac{\triangle y}{\triangle x}[/tex]
From the graph attached,
Given straight line is passing through two points (2, 12) and (4, 24).
Rate of change = [tex]\frac{y_2-y_2}{x_2-x_1}[/tex]
= [tex]\frac{24-12}{4-2}[/tex]
= 6
Rate of change of the line = 6 miles per hour
Therefore, rate of change of the graph will define the speed of Arlene.

Sasha hasn’t won any of the 40 games she has played with her four friends so far. She wants to win at least 20%. How many does she need to win in a row to get 20%?
Answer:
10
Step-by-step explanation:
Given that Sasha has won 0 games in the 40 games she has played.
Let she needs to win x game in a row, so
Total game she played = 40 + x
The number of the game she won is x, which is 20% of the total game she played, so
x = 20% of (40+x)
[tex]\Rightarrow x = 0.2(40+x) \\\\\Rightarrow x = 8+0.2x \\\\\Rightarrow x-0.2x=8 \\\\\Rightarrow 0.8x = 8 \\\\\Rightarrow x = 8/0.8=10.[/tex]
Hence, she needs to win 10 games in a row.

Find the value of the integral from 2 to 6 of the natural log of x, dx using four rectangles of equal width, with each right end-point used to find the height of each rectangle.
Answer: Choice B.
ln(3) + ln(4) + ln(5) + ln(6)
=======================================================
Explanation:
Refer to the diagram below. It shows four rectangles each of base 1. Their height varies depending on the output of the natural log function.
More specifically the heights are ln(3), ln(4), ln(5) and ln(6) from left to right. Note how this corresponds exactly to the points on the y = ln(x) curve such that they are the upper right corners of the Riemann Sum rectangles. These corner points are points A,B,C,D.
Since each base is 1 unit wide, this means each rectangle's area is equal to the height. More thoroughly, we say that
area = base*height = 1*f(x) = f(x), where x takes on the values from {3,4,5,6}
Side note: As the diagram shows, we have an overestimate of the actual area under the curve from x = 2 to x = 5.
Free cookies Just answer this question! Elena solves the equation x^2=7x by dividing both sides by x to get 7. She says
the solution is 7. Lin solves the equation x^2=7 by rewriting the equation to get
x^2-7=0. When she graphs the equation x^2-7=0, the x-intercepts are (0,0) and
(7,0). She says the solutions are 0 and 7. Why should Elena not divide by x?
x could be equal to zero, and we can't divide by zero, so we shouldn't divide by x.
Why should Elena not divide by x?
Here we have the quadratic equation:
[tex]x^2 = 7x[/tex]
Notice that we don't know the value of x, so technically, x could be equal to zero, and we can't divide by zero, so we shouldn't divide by x.
The quadratic equation can be rewritten as:
x^2 - 7x = 0
x*(x - 7) = 0
(x - 0)*(x - 7) = 0
So the two solutions are x = 0 and x = 7, because x = 0 is a solution, we see that x can be equal to zero, so we can't divide by x.

A builder is building a rectangular deck with dimensions of 16 feet by
30 feet. To ensure that the sides form 90° angles, what should each
diagonal measure?
Answer:
Each diagonal should measure 34 feet to ensure that the sides form 90°
Step-by-step explanation:
The relation between the diagonal of the rectangle and its length and width is D = [tex]\sqrt{L^{2}+W^{2}}[/tex] ⇒ Pythagoras Theorem
∵ A builder is building a rectangular deck with dimensions of 16 feet
by 30 feet
∴ L = 16 feet
∴ W = 30 feet
→ By using the Pythagoras Theorem above to find its diagonal
∵ D = [tex]\sqrt{(16)^{2}+(30)^{2}}[/tex]
∴ D = [tex]\sqrt{256+900}[/tex]
∴ D = [tex]\sqrt{1156}[/tex]
∴ D = 34 feet
→ The diagonals of the rectangle are equal
∴ The length of each diagonal of the rectangle = 34 feet
Each diagonal should measure 34 feet to ensure that the sides form 90°

For each representation of a relationship, determine if it is a function or not.
Explain how you know with your answer.
(Giving brainliest to first and correct answer)
Answer:
e is a function; f is not a function
Step-by-step explanation:
All functions must pass the vertical line test. this means that the when those points are plotted, no two points are on the same vertical line. You can tell if they are on the same vertical line by their x-coordinate. If two points have the same x-coordinate, then they are on the same vertical line. This means that the if two points have the same x-coordinate in the relationship, it is not a function. In e, the x-coordinates are 0, 4, 8, and 3. In f, the x-coordinates are 0, 4, 0, and 6. In e, all the x-coordinates are different, so it is a function. In f, however, 0 is a repeated x-coordinate, so it is not a function.

A parachutist's speed during a free fall reaches 264 feet per second. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 10 seconds of free fall? In your computations, assume that 1 meter is equal to 3.3 feet. Do not round your answers.
Speed:
Distance fallen in 10 seconds:
Answer: They will fall 800 meters. And they are falling 80 meters per second.
Step-by-step explanation: You must first take 264 divided by 3.3 which equals 80, then multiply is by 10.
Total distance fallen in 10 seconds is given by the equation A = 800 meter
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the total distance fallen in 10 seconds be represented as A
Now , the value of A is
The parachutist's speed during free fall = 264 feet/second
Now , 1 meter = 3.3 feet
So , 1 feet = ( 1/3.3 ) meter
So , the value of 264 feet = 264 x ( 1/3.3 ) meter
On simplifying the equation , we get
The value of 264 feet/second = 80 meter/second
Now , the distance traveled by the parachutist every second = 80 meter
So , the distance traveled by the parachutist in 10 seconds = 10 x distance traveled by the parachutist every second
Substituting the values in the equation , we get
The distance traveled by the parachutist in 10 seconds A = 10 x 80
On simplifying the equation , we get
The distance traveled by the parachutist in 10 seconds A = 800 meter
Therefore , the value of A is 800 meter
Hence , the total distance is 800 meter
