Step-by-step explanation:
The height that your feet are above the ground is given by the function :
[tex]h(t) = -16t^2 +12t[/tex] ...(1)
We need to find the maximum height your feet will be above the ground.
For maximum height, put dh(t)/dt = 0
[tex]\dfrac{dh}{dt}=0\\\\\dfrac{d( -16t^2 +12t)}{dt}=0\\\\-32t+12=0\\\\t=0.375\ s[/tex]
Now put t = 0.375 s in equation (1) as follows :
[tex]h(t)=-16\left(0.375\right)^{2}+12\left(0.375\right)\\\\=2.25\ ft[/tex]
So, the feet will be 2.25 feet above the ground. Yes, you will be able to dunk the basketball.
What is the equation of a line, in point-slope form, that passes through (-8, 1)and has a slope of ?
O y+1=(x - 8)
Oy+8= 5 (1-1)
oy-1-5(x + 8)
Oy-8= + (x+1)
Answer:
y-1 = 5(x+8)
Step-by-step explanation:
The standard equation of a line in point slope form is expressed as;
y-y0 = m(x-x0)
m is the slope
(x0, y0) is the point
Given
Slope m = 5 (assumed value)
Point (-8,1)
Substitute the given data's into the formula
y -1 = 5(x-(-8))
y-1 = 5(x+8)
Hence the required equation is y-1 = 5(x+8)

Answer:
27
Step-by-step explanation:
the sequence is 4 added to each number. 4 added to 23 is 27
Answer:
C.27
Step-by-step explanation:
We need to find the pattern in order to determine the next term of the sequence. By looking at the terms, we can observe that each one is 4 bigger than the previous term, therefore we can assume that the next term will also be 4 bigger than the last term we are given (23) so we add 4 to that (23+4) and we get 27.
Ms. Sanchez bought 3 pounds of turkey to make sandwiches for her family. She uses 1/3 of a pound for each sandwich. How many sandwiches can she make?
Answer:
the total number of sandwich required is 9
Step-by-step explanation:
The computation of the number of sandwiches made is as follows:
She bought 3 pounds
And one third of pound she required for each sandwhich
So, the total number of sandwich required is
= 3 ÷ 1 ÷ 3
= 3 × 3
= 9
Hence, the total number of sandwich required is 9

You want to save $10,000 to buy a new car You doposit 6500in an account earning 7.5% simple interest. After how long will you have enough money
in the account to purchase the car? Round your answer to the nearest whole number
Answer:
After 7.5 years we will have enough money in the account to purchase the car.
Step-by-step explanation:
Amount needed to be saved = $10000
Principal = $6500
So, Simple Interest = $3500
Rate of Interest = 7.5%
= 0.075
Now, Simple Interest = Principal × Rate × Time
⇒ 3500 = 6500 × 0.075 × Time
⇒ 3500 = 487.5 × Time
⇒ Time = 7.18 years ≈ 7.5 years
Hence, after 7.5 years we will have enough money in the account to purchase the car.

Roll a fair six sided die 1000 times. Out of 1000 rolls how many times an even number
Answer:
500 times!Step-by-step explanation:
the probability of a die showing an even number is 3/6 i.e, 1/2. for one role the probability of getting an even number is 1/2, therfore for a thousand role = 1000 x 1/2 = 500 times.

Kristi rides her bike to school and has an odometer that measures the distance traveled. She subtracts this distance from the distance to the school and records the distance that remains between her and the school. Find the intercepts. What do the intercepts represent?
The y-intercept represents when she starts riding her bike while the x-intercept is the the time it takes her to get to her school.
How to Interpret x and y intercepts?The complete question shows us a table with time travelled being on the x-axis while distance remaining is on the y-axis.
We see from the table that at 0 minutes travelled, the distance remaining is 5500 ft. Thus, the y-intercept represents when she starts riding her bike at 0 minutes and 5500 ft left to cover.
We see also from the table that after 8 minutes covered, she has 0 ft left to travel. Thus, the x-intercept is the the time it takes her to get to her school which is 8 minutes.

Friendship’s soccer team purchased uniforms and equipment for a total of $912. The equipment cost $612 and the uniforms cost $25 each. How many uniforms did the school purchase?
Answer:
12
Step-by-step explanation:
912 - 612 = 300
300 ÷ 25 = 12
The number of uniforms the school purchased based on the given data and equation formation will be $12.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's suppose the school purchase x number of uniforms.
Total cost = equipment cost + x uniforms cost
912 = 612 + 25x
912 - 612 = 25x
25x = 300
x = 12
Hence "The number of uniforms the school purchased based on the given data and equation formation will be $12".

Answer:
This is not a direct variation.Step-by-step explanation:
Direct variation:
mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
(y varies directly with x with a constant variation of k)
[tex]y=kx;\ k\neq0[/tex]
[tex]y=kx\qquad|\text{divide both sides by}\ x\\\\\dfrac{y}{x}=k\Rightarrow \dfrac{y}{x}=constant[/tex]
[tex]21.\\\\x=y+2\qquad|\text{subtract 2 from both sides}\\\\x-2=y\qquad|\text{divide both sides by}\ x\\\\1-\dfrac{2}{x}=\dfrac{y}{x}\ro\dfrac{y}{x}=1-\dfrac{2}{x}\neq constant[/tex]
The hypotenuse of a right triangle is 26 millimeters. One leg of the right triangle is 10 millimeters. What is the length of the other leg? (4 points)
Question 3 options:
1)
18 millimeters
2)
20 millimeters
3)
24 millimeters
4)
28 millimeters
Answer: 24 millimeters
the length of the other leg is x (x > 0)(millimeters)
using Pythagoras theorem with the right triangle, we have:
x² + 10² = 26²
⇔ x² = 26² - 10² = 576
=> x = 24 (mm)
Step-by-step explanation:
Step-by-step explanation:
(26)^2 = (10)^2 + BC^2
676 = 100 + BC^2
576 =BC^2
BC = 24 mm
The total cost in dollars to buy uniforms for the Ping-Pong team can be found using the function c=22.50+5 where u is the number of uniforms bought.if there are at least 7 players but not more than 10 players on the Ping-Pong team, what is a reasonable range for the situation? A.{7,8,9,10} B.{162.50 , 185, 207.50, 230} C. 7≤ x ≤ 10 D. 162.50 ≤ y ≤ 230
answer: b
explanation:
it’s asking for the range so it can’t be c or d because those are used in continuous data only so it’s between a and b but it can’t be a as a is the range of players but b is the range of the cost so the answer would then be b
