The image crosses the x-axis at the points where the function f(x) = (x + 8)(x - 4) equals zero. The points are (-8, 0) and (4, 0).
Explanation:To identify the points where the image of the parabolic lens crosses the x-axis, we should find the roots of the function f(x) = (x + 8)(x - 4). A function crosses the x-axis at its roots, the points where f(x) is equal to zero.
Setting the function equal to zero gives us (x + 8)(x - 4) = 0. We can see the polynomial is already factored. The roots of the equation are x = -8 and x = 4, since these values of x will make the equation equal to zero.
So, the graph of the function crosses the x-axis at the points (-8, 0) and (4,0). This means the correct option is: (–8, 0) and (4, 0)

In a race in which five automobiles are entered and tehre are no ties, in how many ways can the first three finishers come in/
there are 5 ways for 1st place, then there would be 4 ways for 2nd place, then 3 ways for third
5*4*3 = 60 different ways
Answer: The required number of ways is 60.
Step-by-step explanation: Given that there are five automobiles entered in a race and there are no ties.
We are to find the number of ways in which the first three finishers come in.
Since there are 5 automobiles entered in the race, so the number of ways in which first finisher come in is 5.
Now, there are no ties, so the number of ways in which second and third finisher come in are 4 and 3 respectively.
Therefore, the total number of ways in which the first three finishers come in is
[tex]n=5\times4\times3=60.[/tex]
Thus, the required number of ways is 60.
A carnival game allows a group of players to each draw and keep a marble from a bag. The bag contains 5 gold marbles, 25 silver marbles, and 70 red marbles. A player wins a large prize for drawing a gold marble and a small prize for drawing a silver marble. There is no prize for drawing a red marble. At the start of the game, the probability of winning a large prize is 0.05 and the probability of winning a small prize is 0.25. Suppose that the first player draws a silver marble and wins a small prize. What is the probability that the second player will also win a small prize? If a group of four plays the game one at a time and everyone wins a small prize, which player had the greatest probability of winning a large prize? How could the game be made fair for each player? That is, how could you change the game so that each player has an equal chance of winning a prize?
It is given that:
The bag contains 5 gold marbles, 25 silver marbles, and 70 red marbles.
Ques 1)
We are asked to find the probability that the second player will also win a small prize given that the first player wins a small prize.
That is we need to find the conditional probability.
Let A denote the event that first player wins the small prize.
B denote the vent that the second player wins the small prize.
A∩B denote the event that both the player wins the small prize.
Let P denote the probability of an event.
We are asked to find:
P(B|A)
[tex]P(B|A)=\dfrac{P(B\bigcap A)}{P(A)}[/tex]
Now we know that:
[tex]P(A)=\dfrac{25}{100}[/tex]
( Since out of 100 marbles 25 are silver)
Also,
[tex]P(A\bigcap B)=\dfrac{25_C_2}{100_C_2}\\\\\\P(A\bigcap B)=\dfrac{25\times 24}{100\times 99}[/tex]
Hence,
[tex]P(B|A)=\dfrac{24}{99}[/tex]
Hence, the probability that the second player will also win a small prize is:
0.242424
Ques 2)
The probability that the first player will win a large prize is:
5/100
( But the first player draws a silver marble and wins)
The probability that the second player will win a large prize is:
5/99
( Since one marble has been taken out by the first player so the second player is left with 99 choices and here also the second player draws a silver and wins the game)
Similarly,
The probability that the third player will win a large prize is:
5/98
( Since one more marble has been taken out by the second player so the third player is left with 98 choices and here also the third player draws a silver and wins the game)
The probability that the fourth player will win a large prize is:
5/97
Hence, the greatest probability of winning a gold marble is by:
Player 4. ( Since, 5/97 is greater than the rest three probabilities)
Ques 3)
The game can be made fair for each player if all have the equal choices of drawing a marble and this can be done by replacing the marbles that have been drawn out by the previous player.

Use cavalieri's Principle to calculate the exact of an oblique cylinder with a radius of 10 meters and a height of 11 meters.
Answer: Volume of cylinder is 1152.38 m³.
Step-by-step explanation:
Since we have given that
Radius of cylinder = 10 m
Height of cylinder = 11 m
Using Cavalieri's principle , volume of an oblique cylinder is equal to volume of cone.
So, Volume of an oblique cylinder is given by
[tex]V=\frac{1}{3}\pi r^2h\\\\V=\frac{1}{3}\frac{22}{7}\times 10\times 10\times 11\\\\V=1152.38\ m^3[/tex]
Hence, Volume of cylinder is 1152.38 m³.

Answer:
The value of k is 4.
Step-by-step explanation:
Given,
f of x equals 1 over 3 x minus 3,
[tex]\implies f(x)=\frac{1}{3}x-3[/tex]
Also, g of x equals 1 over 3 x plus 1,
[tex]\implies g(x)=\frac{1}{3}x+1[/tex]
Since, g(x) = f(x) + k,
By substituting the values,
[tex]\frac{1}{3}x+1=\frac{1}{3}x-3+k[/tex]
[tex]1=k-3[/tex]
[tex]\implies k = 1+3 = 4[/tex]

Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.20 per pound, how many pounds of lemon drops are need to make the mix cost $1.48 per pound. formulate an equation and then solve it to find how many pounds of lemon drops are needed. show all of your work
L = lemon drops
J = jelly beans
L +J = 100
L=100-J
1.90L + 1.20J=1.48*100
1.90(100-j) +1.20J =148
190-1.90J+1.20J=148
190-0.7J=148
-0.7J=-42
J = 60
L=100-60 = 40
40 pounds of Lemon Drops are needed
Final answer:
40 pounds of lemon drops are needed.
Explanation:
To find out how many pounds of lemon drops are needed to make a 100-pound mix that costs $1.48 per pound, we can set up a system of equations. Let L represent the number of pounds of lemon drops and J represent the number of pounds of jelly beans.
Since the total weight of the mix is 100 pounds:
L + J = 100
Given the cost of lemon drops is $1.90 per pound and jelly beans cost $1.20 per pound, and the entire mix should cost $1.48 per pound:
1.90L + 1.20J = 100 * 1.48
We already have that L + J = 100, so J can be expressed as 100 - L. Substituting J in the second equation we get:
1.90L + 1.20(100 - L) = 148
Solving for L:
1.90L + 120 - 1.20L = 148
0.70L = 28
L = 28 / 0.70
L = 40
Therefore, 40 pounds of lemon drops are needed for the mix.
How many window coverings are necessary to span 50 windows if each window covering is 15 windows long? 3 4 5 6?
To cover 50 windows with coverings that are 15 windows long, at least 4 window coverings are needed to span all the windows.
Explanation:The question asks how many window coverings are necessary to span 50 windows, given that each window covering is 15 windows long. To find out how many window coverings are required, you divide the total number of windows by the length of one window covering. So, we do 50 ÷ 15 which equals approximately 3.33. Since you can't have a fraction of a window covering, you'll need at least 4 full window coverings to span all 50 windows.
find the value of x if angle x measures 102°
The value of x is 13.
The problem at hand has a quadrilateral shape. The problem depicts four angles and sides, with the only known angle being X.
The graphic depicts four sides (quad), and the stick drawn in the center of each side explains the length relationship.
One stick is equal to two sticks, and two sticks are equal to one stick.
Angles Assumed:
X=102 deg
W=(7x+4) deg
Y=(5x-4) deg
Because angle X is 102 degrees, angle Z must also be 102 degrees. A quadrilateral has a total angle of 360 degrees.
So, to find x, do the following:
102 + 102 + 7x + 4 + 5x - 4 = 360
Add the constant terms: 102 + 102 + 4 - 4 = 204
Combine x terms: 7x + 5x = 12x
Substitute the combined terms:
204 + 12x = 360
Isolate x:
12x = 360 - 204
12x = 156
x = 156 / 12
Simplify:
x = 13
Therefore, the solution is x = 13.

What is the rise-over-run value for the relationship represented in the graph?
1 over 35
2 over 17
35
40
Answer:
35
Step-by-step explanation:
In rise over run value ( or slope ),
Rise is the unit that moved up or down while the run is the unit that moved from right to left or from left to right.
In the coordinates plane the difference between the y coordinates shows rise and difference in x coordinates shows run,
Thus, the rise over run value from (2,70) to (3,105) is,
[tex]m=\frac{105-70}{3-2}[/tex]
[tex]=\frac{35}{1}[/tex]
[tex]=35[/tex]
In the given graph a line represents the relation between distance and time,
We know that the rise over run value for a line is same as the rise over run value for any two points in the line.
Hence, the rise-over-run value for the relationship represented in the graph is 35.

Consider the function given by the graph.
What are these values?
f(–2 ) =__
f(0) = __
f(4) = __
Answer:
f(-2 ) =2
f(0) = 3
f(4) = -1
Step-by-step explanation:
Clearly by looking at the graph of the given function f(x) we could observe that the function f(x) is increasing in the interval (-∞,0] and then decreasing in the interval (0,∞).
Also, the function is discontinuous at x=0.
( Since, there is a break in a graph and also the left and right hand limit of the function are not equal at x=0)
Hence, from the graph we could directly say that:
f(-2 ) =2
f(0) = 3
f(4) = -1
The values of the function values are:
f(-2 ) =2, f(0) = 3 and f(4) = -1
The value of f(-2)On the graph, the value of the function when x = -2 is 2
Hence, the value of f(-2) is 2
The value of f(0)On the graph, the values of the function when x = 0 are 1 and 3.
However, the line that has a closed circle (i.e f(0) = 3) will take precedence over the line that has an open circle (i.e f(0) = 1)
Hence, the value of f(0) is 3
The value of f(4)On the graph, the value of the function when x = 4 is -1
Hence, the value of f(4) is -1

Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding. The speed limit is 65 mph and Sally has traveled 97 km in 102 minutes. How fast was Sally's average speed in mph? In a complete sentence, explain whether or not Sally deserves a ticket?
Answer:
35.5 mph
Step-by-step explanation:
We are given that Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding.
Speed limit =65 mph
Sally traveled distance 97 km in 102 minutes
We have to find the Sally's average speed in mph
Time =102 minutes
We know that 1 hour =60 minutes
[tex]102 minutes=\frac{102}{60}=1.7 [/tex]hours
We know that 1 km=0.621371
97 km=[tex]0.621371 \times 97=60.272987[/tex]miles
Average speed =[tex]\frac{60.272987}{1.7}=35.45 mph[/tex]
Average speed of Sally's =35.5 mph
Hence, average speed of Sally is less than 65 mph .Therefore, she was not fast speeding and she deserves a ticket.
