A ball is thrown straight up into the air. The table shows the data collected over t seconds, where h(t) is the height of the ball, in feet.
A 2-column table with 6 rows titled Height of Ball over Time. The first column is labeled t with entries 0, 1, 2, 3, 4, 5. The second column is labeled h(t) with entries 0, 64, 96, 96, 64, 0.
Which statement is true?
The initial height of the ball is 96 feet.
The ball will hit the ground between 2 and 3 seconds after it was thrown.
The maximum height of the ball must be 96 feet.
The maximum height of the ball was 2.5 seconds after it was thrown.

what line y= 2/3 x - 2 is graphed below. if the system comprised of this line and the line y= -2x + 6 were solved, which of the following would be the y-coordinate of the solution?
1) y=0
2) y=7
3) y=3
4) y=-4
plz help asap thank you in advance!! :)
Answer:
(1) y = 0
Step-by-step explanation:
This question uses System of Equations to solve it.
Because both equations are equal to y, we can set both of the equations to equal each other and use basic algebra to solve for x:
2/3x -2 = -2x + 6
8/3x -2 = 6
8/3x = 8
x = 3
Because we are looking for the y-coordinate, plug 3 into one of the equations and solve for y (I'm going to use y = -2x + 6):
y = -2(3) + 6
y = -6 + 6
y = 0
That's your answer!
You can even prove it by using Desmos (this is a free graphing website), write the two equations, and then you can see the point where they intersect (I attached an image below).

The average movie ticket price in dollars since 1980 can be modeled by 0.142x + 1.93 where x is the number of years since 1980. What values of x would you use to find the average movie ticket price in 1985, 1999, and 2010? Find the ticket prices for each of those years rounded to the nearest cent. Submit your x-values, ticket prices, and all solution steps to earn full credit.
Answer:
Step-by-step explanation:
1985:
x = 5 years ( 1980 to 1985- 5 years)
0.142x + 1.93 = 0.142*5 + 1.93
= 0.71 + 1.93
= $ 2.64
1999:
x = 19 years
0.142x + 1.93 = 0.142*19+ 1.93
= 2.698 + 1.93
=4.628 = $ 4.63
2010:
x = 30 years
0.142x + 1.93 = 0.142*30 + 1.93
= 4.26 + 1.93
= $ 6.19

Answer:
A) Over the interval [-2.5, 0.5], the local maximum is 2--------------------------
Hope it helps...
Answer:
(A) Over the interval [-2.5, 0.5], the local maximum is 2.
Step-by-step explanation:
"Over the interval [-2.5, 0.5], the local maximum is 2."
Correct. The local maximum is the maximum, or highest point, of the graph in a certain area of interval. In [-2.5, 0.5], the highest point is at the y-value of 2.
"As the x-values go to positive infinity, the function's values go to negative infinity."
Wrong. As the x values go to positive infinity (meaning they go to the right, or positive side of the graph), the function goes up, meaning the function's values go to positive infinity.
"The function is decreasing over the interval (-1, 0.75)."
Wrong. Only from [-1, 0] is where that area of the graph decreases. The other half of it, (0, 0.75), is where the graph increases.
"The function is negative for the interval [-2, 0]."
Wrong. Only from [-1, 0] is the function negative. In the interval [-2, -1], the function is positive.

What is the probability of rolling a number less than
or equal to 8 with the
sum of two dice, given that at least one of the dice must show a 6?
A. 4/11
B. 7/11
C. 9/11
D. 2/11
Answer:
The correct answer is D. 2/11.
Step-by-step explanation:
To determine what is the probability of rolling a number less than or equal to 8 with the sum of two dice, given that at least one of the dice must show a 6, the following calculation should be performed:
6 + 1 = 7
6 + 2 = 8
2/11 = X
Therefore, the probability of rolling a number less than
or equal to 8 with the sum of two dice, given that at least one of the dice must show a 6, is 2/11.

the radius of a semicircle is 1 kilometer. what is the semicircle's perimeter? use 3.14 for pie.
Answer:
5.14 km
Step-by-step explanation:
A semicircle is 1/2 of a circle so the perimeter is just 1/2 of the circumference
C = 2 * pi r for a circle so for a semicircle
1/2* 2* pi *r
pi*r
3.14 * 1
3.14
If we want to include the piece that closes the semicircle, we need to add the diameter
d = 2r = 2(1) = 2
2+3.14 = 5.14
The median observation are arranged in ascending are 72,74,75,5x-10,3x+30,85,88,94.If the median mark is 82 ,find the value of x
Step-by-step explanation:
The position of the median of an even data set is 1/2(8+1)=4.5
That is between two values, 4 and 5.
(5x-10+3x+30)/2=82
(8x+20)/2=82
(8x+20)=41
8x=41-20
8x=21

Sarah is going from home to school then to the library to study and finally to the part to meet with friends before going home. Find the distance Sarah will travel today based on the locations of each stop on the coordinate plane. Include:
Distances between all 4 locations
Total distance
The method used for each calculation
Sarah’s house (2,-5)
The school (2,4)
Library (-3,4)
Park (-3,-5)
Answer:
i) The distance between Sarah's house and the school is 9
ii) The distance between the school and the library is 5
iii) The distance between the library and the park is 9
iv) The distance between the park and Sarah's house is 5
2) The total distance Sarah travels is 28
Step-by-step explanation:
The given coordinates of the locations are;
Sarah's house (2, -5)
The school (2, 4)
Library (-3, 4)
Park (-3, -5)
Sarah's journey is; From the house → The school → Library → Park → House
The distance, d, between two coordinate points, (x₁, y₁) and (x₂, y₂) is given as follows;
d = [tex]\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
i) Therefore, the distance between Sarah's house ((x₁, y₁) = (2, -5)) and the school ((x₂, y₂) = (2, 4)), d₁, is d₁ = √((2 - 2)² + (4 - (-5))²) = 9
Sarah's house → The school = 9
ii) The distance between the school ((x₁, y₁) = (2, 4)), and the library, ((x₂, y₂) = (-3, 4)), d₂ = √((-3 - 2)² + (4 - 4)²) = 5
The school → Library = 5
iii) The distance between the library ((x₁, y₁) = (-3, 4)), and the park ((x₂, y₂) = (-3, -5)), d₃ = √((-3 - (-3))² + (-5 - 4)²) = 9
The library → The park = 9
iv) The distance between the park ((x₁, y₁) = (-3, -5)), and Sarah's house ((x₂, y₂) = (2, -5)), d₃ = √((2 - (-3))² + (-5 - (-5))²) = 5
The park → Sarah's house → 5
2) The total distance = 9 + 5 + 9 + 5 = 28.
Solve for x the given angle measure at the top right is 57 degrees and the given angle measure in the lower left is (x+3) degrees
Answer:
54
Step-by-step explanation:
the 2 lines are parallel and the line going through is a transversal.
because of vertical angles, the x+3 is equal to the angle diagonal to it.
that diagonal angle is equal to the top right one (57˚) by same side interior angle thereom. So intern, x+3 = 57
x = 54

find the number of letters from the word MAXIMUM where two consonants cannot occur. (Permutation)
Answer:
4!
Step-by-step explanation:
In word MAXIMUM, consonants are M & X. According to the question itself, consonants should not occur together.
So, we have to put vowels at each even position; only then the condition will be satisfied.
We can put this in 3! ways (permutations of A, I & U).
For odd positions we can put 3-M's & a X. Total ways is 4!/3! (as repetitions of M).
Hence, the answer is 4!/3! x 3! = 24 ways.
24=4!.

A worker with a wheelbarrow filled with bricks starts at a point 50 m from the
entrance to a construction site. The worker pushes the wheelbarrow away from the
entrance at a speed of 1 m/s for 10 s, stops for 5 s to unload, and then moves back
toward the entrance at a speed of 2 m/s for 20 s. Draw a distance-time graph.
Answer:
Step-by-step explanation:
initial distance, d = 50 m at t = 0 s
t = 10 s , speed, v = 1 m/s
distance, d' = 1 x 10 = 10 m at t = 10 s
Now t = 10 s to t = 15 s it is at rest
speed, v' = 20 m/s , t' = 20 s
distance, d'' = 2 x 20 = 40 m at t = 15 s to 35 second
The graph is given below:
The function ƒ(x) = 6x is vertically shrunk by a factor of ½ and translated 9 units in the negative y- direction. Select the correct graph of the resulting function.
Answer:
option C.
Step-by-step explanation:
since the graph y = 6x is shrunk by a factor of ½
it becomes y = 3x
to find one coordinate of this graph we put x = 1 so that we get y = 3
so one point we have is (1, 3).
and the other point is origin
[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]
now this graph is translated 9 units in the negative y direction
so the point that initially was (0, 0) now becomes (0, -9).
we see that the only graph passing thru (0, -9) is C.
so the answer is option C.

A golf ball has a diameter of 1.68 inches. What is its volume? Use 3.14 for – and round your answer to the nearest hundredth.
Answer:
Volume of the ball = 2.48 inch³
Step-by-step explanation:
A golf ball is in the shape of a sphere.
Therefore, volume of the ball will be given by,
Volume = [tex]\frac{4}{3}\pi r^{3}[/tex]
Here, r = Radius of the ball
By substituting the value of 'r' in the formula,
Volume of the golf ball = [tex]\frac{4}{3}\pi (\frac{\text{Diameter}}{2})^{3}[/tex]
= [tex]\frac{4}{3}(3.14) (\frac{\text{1.68}}{2})^{3}[/tex]
= [tex]\frac{4}{3}(3.14) (0.84)^{3}[/tex]
= 2.482 inch³
≈ 2.48 inch³
