During halftime of a basketball game, a sling shot launches T-shirts at the crowd. A T shirt is launched from a heigh of 4 feet with an initial upward velocity of 72 feet per second. Use the equation h(t)= -16t^2+72t+4, where t is time in seconds and h(t) is height. How long will it take the T shirt to reach its maximum height? What is the maximum height?
During halftime of a basketball game, a slingshot launches T-shirts at the crowd.
it takes the T-shirt 9/4 secondsThe maximum height of the T-shirt is 77 feet.What is the maximum height?
Generally, To find the time it takes the T-shirt to reach its maximum height, we need to find the time when the height of the T-shirt stops increasing and starts decreasing. At this point, the velocity of the T-shirt will be 0, since it is not moving up or down.
The velocity of the T-shirt at any time t can be found by taking the derivative of the equation for height:
v(t) = dh/dt = -32t + 72
Setting the velocity to 0 and solving for t, we get:
0 = -32t + 72 32t = 72 t = 72/32 t = 9/4
So it takes the T-shirt 9/4 seconds, or approximately 2.25 seconds, to reach its maximum height.
To find the maximum height, we plug this value back into the equation for height:
h(t) = -16(9/4)^2 + 72(9/4) + 4 h(t) = -81 + 162 + 4 h(t) = 77
The maximum height of the T-shirt is 77 feet.

−2(cos x)(sin y)A hat contains 35 marbles. Of them, 20 are red and 15 are green. If one marble is randomly selected out of this hat, what is the probability that this marble is red? Round your answer to two decimal places. P(A) =
Answer:
P(A) = 0.57 (rounded to two decimal places).
Step-by-step explanation:
The probability of selecting a red marble from the hat can be found by dividing the number of red marbles by the total number of marbles:
P(red) = number of red marbles / total number of marbles
P(red) = 20/35
We can simplify this fraction by dividing both the numerator and denominator by 5:
P(red) = 4/7
So the probability of selecting a red marble from the hat is 4/7, or approximately 0.57 when rounded to two decimal places.
Therefore, P(A) = 0.57 (rounded to two decimal places).

"Distance traveled is a function of time." In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.
Distance is a fundamental concept in physics and mathematics that measures the extent or length between two points.
It represents the amount of ground covered or space traveled. When we say that distance is a function of various factors, it means that different variables or parameters can influence the distance traveled.
In the context of motion or travel, the distance traveled is often dependent on the amount of time that has passed.
The sentence "Distance traveled is a function of time" expresses this relationship, indicating that the distance traveled can be determined or calculated based on the value of time.
Thus, it implies that as time changes, the corresponding distance traveled also changes, establishing a functional relationship between the two variables.

Answer:
x=0 or x=−95
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−190x=2x²
Step 2: Subtract 2x² from both sides.
−190x−2x²=2x²−2x²
−2x²−190x=0
Step 3: Factor left side of equation.
(−2x)(x+95)=0
Step 4: Set factors equal to 0.
−2x=0 or x+95=0
x=0 or x=−95
\(~~~~2x^2 =-10 \times 19\\\\\implies 2x^2 = -190\\\\\implies x^2 = -\dfrac{190}2\\\\\implies x^2 = -95\\\\\implies x = \pm\sqrt{-95}\\\\\implies x = \pm \sqrt{-1}\sqrt{95}\\\\\implies x = \pm i\sqrt{95}\)

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

O
A. The graph is stretched vertically and shifted up 1 unit.
B. The graph is compressed horizontally and shifted down 1 unit.
C. The graph is compressed vertically and shifted 1 unit to the left.
D. The graph is stretched horizontally and shifted 1 unit to the right.
Answer:D. The graph is stretched horizontally and shifted 1 unit to the right.
Step-by-step explanation: The absolute value function |s| reflects the part of the graph below the x-axis to above the x-axis, resulting in a V-shape. The modification (s - 1)|s| shifts this V-shape 1 unit to the right and stretches it horizontally by a factor of 1. Therefore, option D is the correct answer.

About the probability density functionProbability density functions are a group of functions commonly used in statistical theory to describe the behavior of theoretical probability distributions. A function satisfies a criterion like the function if its values are always positive for all horizontal axes and its primitives are probability distributions. This means that this function is non-negative for all abscissa values and its definite integral product in the range -∞ to +∞ is equal to 1. Apart from being called the probability density function, it is also called the probability density function or probability density function in the literature.

At the city museum, child admission is $6.60 and adult admission is $9.80. On Sunday, 163 tickets were sold for a total sales of $1363.80. How many adult tickets were sold that day?
ANSWER
\(\text{90 adults}\)EXPLANATION
Let the number of children's tickets sold on Sunday be c.
Let the number of adult tickets sold on Sunday be a.
The total number of tickets sold that day is 163. This implies that:
\(a+c=163\)The total sales that day is $1363.80. This implies that:
\(9.80a+6.60c=1363.80\)From the first equation, make c the subject of the formula:
\(c=163-a\)Substitute that into the second equation and solve for a:
\(\begin{gathered} 9.80a+6.60(163-a)=1363.80 \\ 9.80a+1075.8-6.6a=1363.80 \\ 9.80a-6.6a=1363.80-1075.8 \\ 3.2a=288 \\ \Rightarrow a=\frac{288}{3.2} \\ a=90 \end{gathered}\)Therefore, there were 90 adult tickets sold that day.

Step-by-step explanation:
Financial accounting is an accounting technique used for analyzing, summarizing and reporting of financial transactions like sales costs, purchase costs, account payables and receivables of an organization using standard financial guidelines such as Generally Accepted Accounting Principles (GAAP) and financial accounting standards board (FASB).
This ultimately implies that, it involves specific processes such as recording, summarizing, analysis and reporting of financial transactions with respect to business operations over a specific period of time. Financial experts or accountant uses either the cash basis or accrual basis of accounting.
With regard to financial terminology related to a home or other asset, the word "appreciate" means to grow in value. Thus, an asset that appreciates simply means that it's growing in value over a specific period of time compared to it's initial value.
On the other hand, depreciation can be defined as the reduction of cost of a fixed asset systematically until the value of the asset becomes zero.

The percentage of students with more than 1 brother or sister is 41%.
How to calculate percentage?To find the percentage, first complete the table:
118 - 62 = 56 female students with 1 brother and sister.
8 + 14 = 22 7th years with 3 brothers and sisters.
118 + x + 22 + 6 = 200, x = 200 - 146, x = 54 7th years with 2 brothers and sisters.
54 - 24 = 30 male students with 2 brothers and sisters.
62 + 30 + 8 + y = 104, y = 104 - 100, y = 4 male students with 4 brothers and sisters.
6 - 4 = 2 female students with 4 brothers and sisters.
56 + 24 + 14 + 2 = 96 total female students of 7th year.
The percentage of students with more than i brother and sister is:
54 + 22 + 6 = 82 students or 200 - 118 = 82 students.
