A fireworks company has two types of rockets called Zinger 1 and Zinger 2. The polynomial -16t^2 + 150t gives the height in feet of Zinger 1 at t seconds after launch. The polynomial -16t^2 + 165t gives the height of Zinger 2 at t seconds after launch. If the rockets are launched at the same time and both explode 6 seconds after launch, how much higher is Zinger 2 than Zinger 1 when they explode? 414 ft
90 ft
324 ft
990 ft
Answer:
90 feet
Step-by-step explanation:
If we put t = 6 into both the formulas, we will get the height of each.
Zinger 1:
Height = [tex]-16t^2 + 150t[/tex]
Putting t = 6,
[tex]-16(6)^2 + 150(6)=324[/tex]
Zinger 2:
Height = [tex]-16t^2 + 165t[/tex]
Putting t = 6,
[tex]-16(6)^2 + 165(6)=414[/tex]
The difference in height is 414 - 324 = 90 feet

A gym instructer has a total of 60 hand weights in her studio. Some of the hand weights are 3 pound weights and the rest are 5 pound weights. If their are 10 more 5-lb weights , than how many of each kind does she have?
Answer:
Let's imagine that x is the number of 3 pound weights that the gym instructer has.
Since we know that there are 10 more 5 pound weights, which tells us that the number of 5 pound weight is x + 10, and the total amount is 60 hand weights, we have:
x + x + 10 = 60
2x = 60 - 10
2x = 50
x = 50/2 = 25
So there are 25 3 pound weights at the gym.
From the number we have just found, we also know that the number of the 5 pound weights should be:
60 - 25 = 35 (hand weights)

Roberto's toy car travels at 40 centimeters per second (cm/sec) at high speed and 15 cm/sec at low speed. If the car travels for 25 seconds at high speed and then 45 seconds at low speed, what distance would the car have traveled?
Answer:
1675 cm
Step-by-step explanation:
distance = speed · time
total distance = speed1 · time1 + speed2 · time2
= (40 cm/s)(25 s) + (15 cm/s)(45 s) = 1000 cm + 675 cm = 1675 cm
Roberto's toy car travels 1000 cm at high speed (40 cm/sec for 25 sec) and 675 cm at low speed (15 cm/sec for 45 sec), totaling 1675 cm.
Explanation:To calculate the total distance traveled by Roberto’s toy car, we need to consider the two separate speeds at which the car travels and the time it spends at each speed.
First, we calculate the distance at high speed using the formula distance = speed × time. At high speed, the car travels at 40 cm/sec for 25 seconds, so we multiply these two values to get the distance:
Distance at high speed = 40 cm/sec × 25 sec = 1000 cm
Next, we calculate the distance at low speed, where the car travels at 15 cm/sec for 45 seconds:
Distance at low speed = 15 cm/sec × 45 sec = 675 cm
Finally, we add these two distances together to find the total distance traveled by the toy car:
Total distance = Distance at high speed + Distance at low speed = 1000 cm + 675 cm = 1675 cm
Therefore, Roberto’s toy car would have traveled 1675 centimeters in total.
In the playoffs, the Algenauts won their division playoff series 3 games to 1 and then beat their arch-rivals the Geometers in the League Championship series 4 games to 2. If the Algenauts won 80% of their home playoff games and 60% of their away playoff games, what percentage of their playoff games were at home?
Answer:
h = 48
Step-by-step explanation:
So they played 48 home games. They won 3/4, so they won 36 and lost 12.
They played 48 away games. They won 2/3, so they won 32 and lost 16.
All tolled, they won 36 + 32 = 68 games and lost 12 + 16 = 28 games.
To calculate the percentage of home playoff games played by the Algenauts, we use a system of equations with the known win rates and number of games played. Solving, we find that approximately 71.43% of their playoff games were at home.
The student is asking about the percentage of home playoff games played by the Algenauts. The Algenauts won 3 division playoff games and then beat their rivals, the Geometers, with a score of 4-2. Given their win rates of 80% for home games and 60% for away games, we can calculate the percentage of games played at home using a system of equations.
Let H be the number of home games and A be the number of away games. Since the Algenauts played a total of 3 + 4 = 7 games, and won 3 + 4 = 7 games, we have the following equations:
H + A = 7 (total games)
0.80H + 0.60A = 7 (total games won)
Solving the system of equations, we get H = 5 and A = 2, meaning 5 out of the 7 games were played at home. Therefore, the percentage of home games is (5/7) * 100, which equals approximately 71.43%.

B. Both graphs have been shifted and flipped.
C. Both graphs are logarithmic functions.
D. Both graphs are exponential functions.
Answer:
Step-by-step explanation:
Given are two graphs. f(x) will have x axis as asymptote while x=2 is asymptote for g(x).
Hence both graphs have exactly one asymptote

Answer:
5a. approximately 6 grams remain after 2 seconds
5b. The graph shown cannot be a solution. The solution has negative slope everywhere.
5c. y = 50/(t+5)
5d. The amount is changing at a decreasing rate. (As y gets smaller, so does the magnitude of dy/dt.)
Step-by-step explanation:
5a. The tangent line has the equation ...
y = f'(0)t +f(0)
Here, that is
y = -0.02·10²·t +10 = 10 -2t
Then at t=2, the value is ...
y = 10 -2·2 = 6 . . . . grams remaining
__
5b. y² is always positive (or zero), so -0.02y² will be negative. This is dy/dt, the slope of the curve with respect to time, so any curve with positive slope somewhere cannot be a solution.
__
5c. The equation is separable so can be solved by integrating ...
∫y^-2·dy = -0.02∫dt
-y^-1 = -0.02t +c . . . . for some arbitrary constant c
Multiplying by -50 gives ...
50/y = t + c . . . . for some constant c
We can find the value of c by invoking the initial condition. At t=0, y=10, so we have ...
50/10 = 0 +c = 5
Then, solving for y, we get ...
y = 50/(t+5)
__
5d. As noted above (and as described by the differential equation), the magnitude of the rate of change is proportional to the square of y. As y decreases, its rate of change will also decrease (faster). You can see that the curve for y flattens out as t increases. The amount of the substance is changing at a decreasing rate.

Assuming a 95% confidence level, which of the following statements holds true?
A. As the sample size is appropriately large, the margin of error is ±0.032.
B. As the sample size is too small, the margin of error is ±0.032.
C. As the sample size is appropriately large, the margin of error is ±0.0265.
D. As the sample size is too small, the margin of error cannot be trusted..
I think the answer is A. am I correct?
A is the correct answer
Answer:
The correct option is A.
Step-by-step explanation:
An organization consists of 8,684 employees. The organization surveyed 884 of their employees and found that 36% of those surveyed disliked the new vacation policies. It means
[tex]n=884[/tex]
[tex]p=\frac{36}{100}=0.36[/tex]
The value of z-score for 95% confidence level is 1.96.
The formula for margin of error is
[tex]ME=z\times \sqrt{\frac{p(1-p)}{n}}[/tex]
Where, z is z-score at given confidence level, p is sample proportion and n is number of samples.
[tex]ME=\pm 1.96\times \sqrt{\frac{0.36(1-0.36)}{884}}[/tex]
[tex]ME=\pm 0.0316425[/tex]
[tex]ME\approx \pm 0.032[/tex]
The margin of error is ±0.032 and the sample size is appropriately large. Therefore, the correct option is A.

A 25-foot ladder leans against a wall. The base of the ladder is 15 feet from the bottom of the wall. How far up the wall does the top of the ladder reach?
Answer: 20 feet.
Step-by-step explanation:
Observe the right triangle attached.
You need to find the value of "x".
Then, you can use the Pythagorean Theorem:
[tex]a^2=b^2+c^2[/tex]
Where "a" is the hypotenuse of the triangle, and "b" and "c" are the legs.
In this case, you can identify that:
[tex]a=25ft\\b=15ft\\c=x[/tex]
Substitute these values into [tex]a^2=b^2+c^2[/tex]:
[tex](25ft)^2=(15ft)^2+x^2[/tex]
Now, you need to solve for x to find how far up the wall the top of the ladder reaches. Then you get:
[tex]x^2=(25ft)^2-(15ft)^2[/tex]
[tex]x=\sqrt{(25ft)^2-(15ft)^2}[/tex]
[tex]x=20ft[/tex]
ANSWER
20ft
EXPLANATION
The ladder, the wall and the ground formed a right triangle.
Let how far up the wall does the top of the ladder reached be x units.
The 25ft ladder is the hypotenuse.
The shorter legs are, 15ft and x ft
Then from Pythagoras Theorem,
[tex] {x}^{2} + {15}^{2} = {25}^{2} [/tex]
[tex] {x}^{2} + 225 = 625[/tex]
[tex] {x}^{2}= 625 - 225[/tex]
[tex]{x}^{2}= 400[/tex]
[tex]x = \sqrt{400} [/tex]
[tex]x = 20ft[/tex]
Therefore the ladder is 20 ft up the wall.

B. slope: 1/2 mile/minute; the slope represents the speed of the car
C. correlation
Step-by-step explanation:
A. The points in the table lie on a straight line, so the correlation coefficient is exactly 1.
__
B. The ratio of distance to time is speed. That ratio for this data is 10 miles/20 minutes = 1/2 mile/minute. This is the slope of the graph.
__
C. Passage of time does not cause the car to go any particular distance, nor does the car's traveling cause time to pass. The best that can be said is that the car's distance traveled is strongly correlated with the time it takes. (The reason the car goes some distance is likely due to a cause not mentioned in the problem statement, for example, it was switched on and the motor started.)

The solution is (1, 5)
B.
The solution is (21, 0)
C.
There are an infinite number of solutions.
D.
There is no solution.
Answer:
4. No solution
Step-by-step explanation:
To solve a system of equations, find the (x,y) solution that satisfies both equations. One method that can be used is substitution. It is done by substituting one function into the other function and simplify.
Substitute y = 4x - 6 into 8x - 2y = 14.
8x - 2(4x - 6) = 14
8x - 8x + 12 = 14
12 = 14 FALSE
Since the variable was eliminated and a false statement was found, there is no solution to this system.
Solve 3 and 5 similarly. If the variable is eliminated again, but a true statement is fund then the solution is infinite. If the variable is not eliminated then substitute it back into one equation to find the other.
Final answer:
Using the substitution method, we find that Problem 4 has no solution (D), Problem 3 also has no solution (A), and Problem 5 has an infinite number of solutions (C).
Explanation:
To solve the given systems of equations using the substitution method, we substitute the expression for y from the first equation into the second equation and solve for x. Once x is found, we plug it back into the first equation to find y.
Problem 4:
Starting with the equations:
y = 4x – 6
8x – 2y = 14
We substitute the first equation into the second equation:
8x – 2(4x – 6) = 14
Solving for x:
8x – 8x + 12 = 14
x = 1/2 (not a solution, as the x terms cancel out)
Since the equation simplifies to 12 = 14, which is not true, we conclude that:
Option D. There is no solution.
Problem 3:
The system appears similar:
y = 3x – 7
6x – 2y = 12
Substitution gives:
6x – 2(3x – 7) = 12
And solving for x:
6x – 6x + 14 = 12
Which simplifies to 14 = 12, another impossibility.
So the answer is:
Option A. There is no solution.
Problem 5:
From our system:
y + 2x = 7
14 – 4x = 2y
We express y from the first equation:
y = 7 – 2x
Substitute it into the second one, and solve for x:
14 – 4x = 2(7 – 2x)
14 – 4x = 14 – 4x
This equation is true for all x; hence, y can be found for any corresponding x and the system has infinite solutions:
Option C. There are an infinite number of solutions.

If f(x) = x^2 I horizontally compressed to g(x) which could be the equation of g(x)?
A. [tex]g(x) =( \frac{1}{5} x)^2[/tex]
B. [tex]g(x) = x^2+5[/tex]
C. [tex]g(x) = (5x)^2[/tex]
D.[tex]g(x) = (x-5)^2[/tex]
Answer: Option C.
Step-by-step explanation:
For a parent function [tex]f(x)=x^2[/tex], you have these transformations:
If [tex]f(x)=c(x^2)[/tex] and [tex]0 <c <1[/tex] then the graph is compressed vertically by a factor "c".
If [tex]f(x)=c(x^2)[/tex] and [tex]|c| > 1[/tex] then the graph is stretched vertically by a factor "c"
If [tex]f(x)=(cx)^2[/tex] and [tex]0 <c <1[/tex] then the graph is stretched horizontally by a factor "c"
If [tex]f(x)=(cx)^2[/tex] and [tex]|c| > 1[/tex] then the graph is compressed horizontally by a factor "c"
In this problem we have the function [tex]f(x)=x^2[/tex] and we know that this is horizontally compressed to g(x), then the transformation is:
[tex]f(x)=(cx)^2[/tex] and the factor must be [tex]|c| > 1[/tex]
You can observe that the option that shows this form is the option C. Therefore, the equation of g(x) is:
[tex]g(x) = (5x)^2[/tex]
Where [tex]|5| > 1[/tex]
A horizontal compression of the function f(x) = x² is represented by the function g(x) = (5x)², where x is multiplied by a constant greater than 1, causing the function to be 'squeezed' together along the x-axis.
Explanation:The question is asking for a horizontal compression of the function f(x) = x². A horizontal compression occurs when we multiply the x by a constant greater than 1 inside the function parentheses. This affects the rate at which the function grows horizontally.
A good way to visualize this is by thinking of the x-axis being 'squeezed' together. Given the choices, the function that represents a horizontal compression of f(x) = x² is C: g(x) = (5x)². In this case, we are multiplying x by a constant (5), thus compressing the function horizontally compared to the original function.

PLEASE HELP! If you apply the changes below to the quadratic parent function, f(x) = x2, what is the equation of the new function?
Shift 1 unit right.
Vertically stretch by a factor of 5
Reflect over the x-axis
Answer:
Step-by-step explanation:
By the way, please use the symbol " ^ " to indicate exponentiation:
f(x) = x^2
Shifted 1 unit to the right, we get g(x) = (x - 1)^2
Vertically stretched by a factor of 5, we get h(x) = 5(x - 1)^2
Reflected over the x-axis: j(x) = -5(x - 1)^2
Answer:
The correct option is A.
Step-by-step explanation:
The quadratic parent function is
[tex]f(x)=x^2[/tex]
The translation is defined as
[tex]g(x)=k(x+a)^2+b[/tex] .... (1)
Where, k is vertical stretch, a is horizontal shift and b is vertical shift.
If |k|>1, then graph of parent function stretch vertically by factor |k| and if 0<|k|<1, then parent function compressed vertically by factor |k|. Negative k represents the reflection across x axis.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
The graph shift 1 unit right,vertically stretch by a factor of 5 , reflect over the x-axis. So, a=-1, |k|=5 and k=-5
Substitute a=-1 and k=5 in equation (1).
[tex]g(x)=-5(x+(-1))^2+(0)[/tex]
[tex]g(x)=-5(x-1)^2[/tex]
Therefore the correct option is A.

Twenty percent of candies in a package are red. The rest are another color.
Simulate randomly checking 20 packages for red candies using these randomly generated digits. Let the digits 1 and 2 represent a red candy.
91027 18200 74536 83514
Approximately how many red candies will be in the packages?
Answer:
Step-by-step explanation:
The probability of picking a red candy from a full bag is 0.20.
But we also have experimental information represented by those 20 digits, each of which tells us how many red candies are in each package.
In the 2nd package there is 1 red candy. In the fourth there is 1 red candy (since 2 represents a red candy, just like 1 represents a red candy).
Next, in the 6th and 8th packages there is 1 red candy each. Finally, in the 19th package there is 1 red candy. Now add up these results: the number of red candies is 1 + 1 + 1 + 1 + 1, or 5. This seems to indicate that there will be 5 red candies in the entire 20 packages.
