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.

A dog walker service offers a daily service and a weekly service in the winter the ratio of daily customers to weekly customers was one to five however in the spring more customers moved to the daily service because of the nicer weather after the weather changed the ratio was 4:2 if there were 1:5weekly customers in the winter then how many daily customers were there in the spring
Answer:
Daily customers were there in the spring = 100 customers
Step-by-step explanation:
In winter :
Daily customers to weekly customers = 1:5
In spring
Daily customers to weekly customers = 4:2
And total weekly customer in winter = 125
Find:
Daily customers were there in the spring
Computation:
Total customer in winter = 125[6/5]
Total customer in winter = 150
Daily customers were there in the spring = 150 [4/6]
Daily customers were there in the spring = 100 customers
What is the sum of the one hundredth of 25, one tenth of thirty and one thousandth of 60?
Answer:
331/100 or 3 31/100
Step-by-step explanation:
We have;
One - hundredth of 25 = 1/100 × 25 = 1/4
One-tenth of 30 = 1/10 × 30= 30/10 =3
One-thousandth of 60= 1/1000 × 60= 60/1000= 3/50
So we have:
1/4 + 3 + 3/50 = 331/100 or 3 31/100

A triangle on a coordinate plane is translated according to the rule T-3, s(x, y). Which is another way to write this rule?
O K.y) - «-3, y + 5)
O (.y)- -3.y- 5)
O (x.y)- (x+ 3, y-5)
O «.y) - («+3, y + 5)
Answer:
The rule indicates that the original (x, y) coordinates will be moved to the left by 3 units and up by 5 units.
Thus,
(x, y) ⇒ (x – 3, y + 5)Step-by-step explanation:
Given the rule T–3, 5(x, y)
The rule indicates that the original (x, y) coordinates will be moved to the left by 3 units and up by 5 units.It means we need to subtract 3 units from the x-coordinate and add 5 units in the y-coordinate.
Thus, if a triangle on a coordinate plane is translated according to the
rule T-3, s(x, y), then another way to write this rule will be:
(x, y) ⇒ (x – 3, y + 5)

If the perimeter of the triangle is 40 cm, find the area of the triangle.
The area of the triangle is, ? cm2.
Answer:
102 cm²Step-by-step explanation:
Perimeter is:
P = 40 cmand P = 2x - 4 + 5x - 13 + x + 9 = 8x - 8Comparing the value:
8x - 8 = 40 8x = 48x = 8 cmAre formula:
A = 1/2ahReplacing values:
A = 1/2(x + 9)(2x - 4)A = 1/2(8 + 9)(2*8 - 4) = 1/2*17*12 = 102 cm²Answer:
60cm²
Step-by-step explanation:
To find :-
The Area of the triangle .We know that Perimeter is the sum of sides of a triangle. Here the perimeter is 40cm .
→ 2x - 4 +5x - 13 + x + 9 = 40cm .
→ 8x - 8 = 40cm
→ 8x = 40+8 cm
→ 8x = 48 cm
→ x = 6cm .
We know that the area of the triangle is half the product of base and height .
Base = x + 9 = 15cm Height = 2x -4 = 8cm .→ A = 1/2 × b × h
→ A = 1/2 × 8cm × 15cm
→ A = 60cm²

A computers random number generator produces random integers from 1 - 50. What is the probability that the first three integers generated for single digit numbers
Answer:
9/50
Step-by-step explanation:
There are nine single digit numbers from integers 1-50 so in order to calculate the probability of getting 3 random numbers from 1-50 to be single digits:
Probability = number of favorable outcomes /total number of outcomes
Therefore Probability of getting 3 single digits randomly from 1-50 = 9/50

Problem A park has a large circle painted in the middle of the playground area. The circle is divided into 444 equal sections, and each section is painted a different color. The radius of the circle is 10 \text{ meters}10 meters10, start text, space, m, e, t, e, r, s, end text. What is the area AAA of each section of the circle? Give your answer in terms of pi. A=A=A, equals \text{m}^2m 2 start text, m, end text, squared
Answer:
25[tex]\pi\ m^2[/tex]
Step-by-step explanation:
Given that:
A large circle in the park has its middle part painted.
The circle is divided in 4 equal parts.
Radius of the circle = 10 meters
To find:
Area of each section of the circle, [tex]A[/tex] = ?
Solution:
Here, we need to find the area of the bigger circle first and then need to divide it into 4 equal parts to find out the answer.
First of all, let us have a look at the formula for area of a circle with given radius [tex]r[/tex]:
[tex]Area = \pi r^2[/tex]
Here, [tex]r = 10 m[/tex]
Putting the value in the above formula, we get:
So, area = [tex]\pi 10^2 = 100\pi\ m^2[/tex]
Now, there are 4 equal parts of the circle, therefore area of each section will be equal.
Area of each section of the circle:
[tex]\dfrac{100\pi}{4} = \bold{25 \pi}\ m^2[/tex]

an=81,d=-3,n=18 solve the question by using formula an=a+(n-1)d
Step-by-step explanation:
An = A + (n - 1)d
We have An = 81, d = -3 and n = 18.
Hence A = An - (n - 1)d = 81 - (17)(-3) = 132.

Jack is age 45 and owns a self-only high deductible health policy with a $7,000 deductible under his HSA. What is his maximum permitted HSA contribution in 2020?
Answer:
$3350
Step-by-step explanation:
HSA holders have the opportunity to keep a certain amount in reserve up to $3350 for an individual and $6650 for a family. Those that are 55 and older have the opportunity to accumulate an additional $1000 which implies that $4350 per individual and $7650 per family, in which these contributions require 100% tax -deductible at gross income.
Thus, the maximum permitted HSA contribution in 2020 for Jack is $3350.
The maximum permitted HSA contribution in 2020 for jack is $3350.
A health savings account (HSA) is a tax-advantaged savings account a family or individual can use to pay for qualified medical expenses. HSAs are paired with a high-deductible health plan (HDHP) and have annual contribution limits. Each year, the IRS HSA rules adjust the guidelines regarding HDHPs and HSA contribution limits.
HSA holders have the opportunity to keep a certain amount in reserve up to $3350 for an individual and $6650 for a family. Those that are 55 and older have the opportunity to accumulate an additional $1000 which implies that $4350 per individual and $7650 per family.

You want to know the opinions of dog owners across America on the issue of establishing a law requiring individuals who own pit bulls to obtain insurance for their dogs. You obtain a list of all registered dog owners and mail a survey to a random sample of 5,000 owners. Of those, 2,389 responded and 22% say that they favor the law. Which of the following statements is true?
Because random sampling is used, we can feel confident the percentage of all dog owners who say they favor insurance for pit bulls is close to 22%.
Because less than half of those who were mailed the survey actually responded, we can feel fairly confident that the actual percentage of all dog owners who say they favor pit bull owners getting insurance for their dog is close to 22%.
We cannot trust these results because the survey was mailed. Only survey results from face-to-face interviews are considered valid.
