10. You're conducting a vertical jump test on your athletes. This individual just broke the school record
(woohoo!) and achieved a height of 40 inches (1.016m). Calculate their 1) initial velocity and 2) flight time.
1.016m
The jump of the athlete to 40 inches, (1.016 m) is obtained using an initial velocity and time calculated as follows;
1) The initial velocity of the athlete is approximately 4.475 m/s
2) The time of flight which is the time to reach 40 inches and back is approximately 0.91 seconds
Which equation can be used to calculate the velocity and time of the motion?The height achieved by the athlete, h = 40 inches
40 inches = 1.016 mRequired;
1) The initial velocity
Solution;
From the kinematic equation of motion, for a free fall, we have;
v² = u² - 2•g•hWhere;
v = The velocity at the final point = 0 (The athlete stops upward motion at the 1.016 m height and starts downward motion
u = The initial velocity
g = Acceleration due to gravity ≈ 9.81 m/s²
h = The height = 1.016 m
Which gives;
0² = u² - 2 × 9.81 × 1.016
u² = 2 × 9.81 × 1.016 ≈ 19.93392
u = √(19.93392) ≈ 4.465
The initial velocity of the athlete, u, is approximately 4.465 m/s2) The flight time;
The flight time can be found using the equation;
v = u - g•tWhich gives;
t = (u - v)/g
Where;
t = The time taken to reach maximum height.
Therefore;
t ≈ (4.465 - 0)/9.81 ≈ 0.455
The time taken to reach the record height is the same as the time to land back on the ground, which gives;
Time of flight = t + t = 2•t
The time of flight ≈ 2 × 0.445 ≈ 0.910
The time of flight is approximately 0.91 seconds.

How many quarts of pure antifreeze must be added to 3 quarts of a 10% antifreeze solution to obtain a 30% antifreeze solution?
_quart(s) of pure antifreeze must be added.
There are 0.857 quarts of pure antifreeze that must be added to 3 quarts of a 10% antifreeze solution to obtain a 30% antifreeze solution.
What is the percentage?
The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that there is 10% times 3 quarts or 0.3 quarts of antifreeze in the current mix and we want a 30% solution.
Let the amount of pure antifreeze to be added would be x
The equation to solve becomes,
⇒ (0.3 + x )/(3 + x) = 0.3
⇒ (0.3 + x ) = 0.3 × (3 + x)
⇒ (0.3 + x ) = 0.9 +0.3x
⇒ 0.7x = 0.6
⇒ x = 0.857
Therefore, we need to add 0.857 quarts of pure antifreeze to the current solution to make a 30% solution.

Use the GCF and the Distributive Property to find the sum of 38 + 57
Answer:
95
Step-by-step explanation:
You want the sum of 38 and 57 by making use of the GCF and the distributive property.
GCFThe GCF of two numbers can be found by looking at their difference (or their remainder when one divides the other). Here, that is ...
57 -38 = 19
This value is a factor of both numbers, so is their GCF.
Distributive propertyThe distributive property tells us how to express the sum with the GCF factored out:
38 +57 = 19(2 +3)
Then the sum is ...
19(2 +3) = 19(5) = 95
The sum is 95.

a company sold yogurt in 120 g pots and one-eight of the content of the pots was chopped fruit, it is then decided to make the pots of yogurt 2/3 of their original weight with 1/5 fruit. will the company use more or less fruit per new design?
Answer:
More fruit for the new design.
Step-by-step explanation:
120 times 2/3 is 80.
1/5 of 80 is 16.
1/8 of 120 is 15.
15 < 16, so the second design has more fruit.

Use the formula for computing future value using compound interest to
determine the value of an account at the end of 4 years if a principal
amount of $2,500 is deposited in an account at an annual interest rate of
5% and the interest is compounded daily. (Assume there are 365 days in
a year.)
The amount after 4 years will be $
(Round to the nearest cent as needed.)
The Total amount after 4 years will be $3000 and interest will be $500.
The rate at which you borrow or lend money is called the simple interest. If a borrower takes money from a lender, an extra amount of money is paid back to the lender. The borrowed money which is given for a specific period is called the principal. The extra amount which is paid back to the lender for using the money is called the interest.
You calculate the simple interest by multiplying the principal amount by the number of periods and the interest rate. Simple interest does not compound, and you don’t have to pay interest on interest. In simple interest, the payment applies to the month’s interest, and the remainder of the payment will reduce the principal amount.
The simple interest calculation's mathematical formula:
A = P (1+rt)
P = Principal Amount
R = Rate of interest
t = Number of years
A = Total accrued amount (Both principal and the interest)
Interest = A – P.
Total amount after 4 years
⇒ $2,500 (1+5%×4)
⇒ $2,500 ×1.2\
⇒ $3000
interest= $3000 - $2,500= $500.

Based on the calculations, the IQR of this data is equal to 2.
How to determine the IQR of this data?
IQR is an acronym for interquartile range and it is a measure of the middle 50% of data values when they are ordered from lowest to highest.
Next, we would order the data from lowest to highest and then determine the median as follows:
Data = {1, 4, 4,} 4, {4, 6, 5}
Median = 4.
For Q₁ of the lower half of the data, we have:
Lower half = {1, 4, 4,}
Q₁ = 4.
For Q₃ of the upper half of the data, we have:
Upper half = {4, 6, 5}
Q₃ = 6.
Mathematically, IQR is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):
IQR = Q₃ - Q₁
IQR = 6 - 4
IQR = 2.
