A soccer ball is kicked from the ground with an initial upward velocity of 64 meters per second, and the height of the ball can be represented by the equation h = -16t^2 + 64t. After how many seconds will the ball hit the ground?
Answer:
t = 2 seconds
Step-by-step explanation:
Given that,
h = -16[tex]t^{2}[/tex] + 64 t
where h and t have their usual meaning.
To determine the number of seconds required of the ball to hit the ground, differentiate the given equation with respect to t.
0 = -32 + 64
So that,
32t = 64
t = [tex]\frac{64}{32}[/tex]
t = 2
The ball will hit the ground in 2 seconds.

Trinity and Peyton were collecting box tops for their class. Trinity collected 36 box tops. Peyton collected
1 ½ times as many. How many cans did they collect all together?
Note: We need to find the number of total box tops instated of total number of cans.
Given:
Trinity collected 36 box tops.
Peyton collected [tex]1\dfrac{1}{2}[/tex] times as many as Trinity.
To find:
The number of box tops they did collect all together.
Solution:
It is given that,
Number of box tops collected by Trinity = 36
Number of box tops collected by Peyton = [tex]1\dfrac{1}{2}\times 36[/tex]
= [tex]\dfrac{3}{2}\times 36[/tex]
= [tex]54[/tex]
Total = [tex]36+54[/tex]
= [tex]90[/tex]
Therefore, the total number of box tops collect all together is 90.

HELP!!!!!Which property can you apply to Hayley's expression to show that it is equivalent to Gretchen's expression?
Complete question :
Gretchen and her friend Hayley bought three bags of apples and three bunches of bananas from the fruit vendor. Gretchen and Hayley want to find the total number of pieces of fruit that they bought. Gretchen thinks she should multiply 3 by the number of apples in each bag, x, and add it to 3 times the number of bananas in each bunch, y, to find the total number of pieces of fruit. Hayley thinks Gretchen should add the number of apples in each bag, x, to the number of bananas in each bunch, y, and then multiply that sum by 3.
Which property can you apply to Hayley’s expression to show that it is equivalent to Gretchen’s expression?
Answer:
The distributive property of multiplication
Step-by-step explanation:
Number of apples per bag = x
Number of bananas per bunch = y
3 each of bananas and apples were bought
Expression to obtain the total fruits bought :
Gretchen's expression :
3x + 3y
Haley's expression :
3(x + y)
According to the distributive property :
Haley's equation :
3(x + y)
(3 * x) + (3 * y)
3x + 3y
Hence, Gretchen's expression = Haley's expression by the distributive property of multiplication.

Answer:
The length of the side DE is approximately 541.3 feet long.
Step-by-step explanation:
There is a trigonometry law called the law of sines, which states the sine of an angle divided by its opposite side is equivalent to the sine of all the other angles in that right triangle divided by its corresponding opposite side. You can use this law to help you solve for x. By applying the law of sines, you'll get that [tex]\frac{sin(90^{o})}{x} =\frac{sin(10^{o})}{94}[/tex] ⇒ [tex]\frac{x}{sin(90^{o})} =\frac{94}{sin(10^{o})}[/tex] ⇒ [tex]x = \frac{94*sin(90^{o})}{sin(10^o)}[/tex] ⇒ [tex]x=541.3ft.[/tex]

Find the surface area of the pyramid. The side lengths of the base are equal. Square pyramid with base edge of 12 centimeters, and a slant height measuring 17 centimeters, on a triangular face. The surface area is square centimeters.
Answer:
the surface area of the square pyramid is 576.66 cm^2
Step-by-step explanation:
The computation of the surface area of square pyramid is given below:
A = a^2 + 2a × √a^2 ÷ √4 + √h^2
where
a = 12 cm
h = 17 cm
Now put the value of a and h in the above formula
= 12^2 + 2(12) × √12^2 ÷ √4 + √17^2
= 576.66 cm^2
hence, the surface area of the square pyramid is 576.66 cm^2

Colton sold a total of 28 tee shirts and sweatshirts as a fundraiser for his football team. If tee shirts cost 12 dollars each and sweatshirts cost 20 dollars each and he raised a total of 424 dollars how many tee shirts did he sell?
Answer:
17
Step-by-step explanation:
Create a system of equations where t is the number of t shirts he sold, and s is the number of sweatshirts he sold
t + s = 28
12t + 20s = 424
Solve by elimination by multiplying the top equation by -20, then adding them together
-20t - 20s = -560
12t + 20s = 424
-8t = -136
Solve for t:
t = 17
So, Colton sold 17 t shirts

In a class of 19 students, 12 are female and 13 have an A in the class. There are 4 students who are male and do not have an A in the class. What is the probability that a student chosen randomly from the class does not have an A?
answer is
6/19
× whats the point of this
The likelihood of selecting a classmate at random who does not have an A is 6/19.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
To find the probability of a student not having an A, we need to first find the total number of students who do not have an A.
The number of students who have an A is 13, so the number of students who do not have an A is:
19 - 13 = 6
Out of these 6 students, 4 are male and 2 are female.
So, the probability of choosing a student randomly who does not have an A is:
P(not A) = number of students without an A / total number of students
P(not A) = 6 / 19
Therefore, the probability of choosing a student randomly from the class who does not have an A is 6/19.

Angie and Kenny play online video games. Angie buys 2 software packages and 3 months of game play. Kenny buys 1 software package and 1 month of game play. Each software package costs $30. If their total cost is $170, what is the cost of one month of game play?
Answer:
$20
Step-by-step explanation:
Kenny's gameplay: 1 month
Angie's gameplay: 3 months
1+3= 4
Kenny bought 1 software pack
Angie bought 2 software packs
1+2= 3
Each software package= $30
So 30×3= 90
Total cost= $170
170-90= 80
80÷4= $20
