The bean bag’s path is part of a curve that is a parabola and to the nearest second, the bean bag was in the air for 1 second(s).
What is projectile motion?Projectile motion is the motion of the body, when it is thrown in the air taking the action of gravity on it.
The parametric equation for x and y can be given as,
\(x =x_o+ v_o\cos(\theta)t \\y =y_o -\dfrac{1}{2}at^2 + (v_o\sin(\theta))t\)
Here, (vo) is the initial speed, (h) is the height and θ is the angle of throw.
The player throws a bean bag from the height of 3 feet with an initial velocity of 34 feet per second at an angle of 30º.
Let suppose the time is t second. Thus, the parametric equation that represents this situation are,
\(x = (34\cos(30^o)t \\y = -16t^2 + (34\sin(30^o))t + 3\)
The bean bag’s path is part of a curve. This path is in the form of parabola.
To the nearest second, the bean bag was in the air for 1 second(s).
Thus, the bean bag’s path is part of a curve that is a parabola and to the nearest second, the bean bag was in the air for 1 second(s).

Complete this sequence of numbers such that the difference between any two adjacent numbers is the same : 3/k, _, _, 9/2k.
The completed sequence is: 3/k, 3/k, 3/k, 9/2k.To complete the sequence of numbers with a constant difference between adjacent numbers, we can calculate the common difference by subtracting the first term from the second term.
Let's denote the missing terms as A and B.
The given sequence is: 3/k, A, B, 9/2k.
The common difference can be found by subtracting 3/k from A or B. Therefore:
A - 3/k = B - A = 9/2k - B.
To simplify, we can equate the two expressions for the common difference:
A - 3/k = 9/2k - B.
Next, we can solve for A and B using this equation.
Adding 3/k to both sides gives:
A = 3/k + 9/2k - B.
Now, we can substitute the value of A into the equation:
3/k + 9/2k - B - 3/k = 9/2k - B.
Simplifying further, we have:
9/2k - 3/k = 9/2k - B.
Cancelling out the common terms, we find:
-3/k = -B.
Multiplying both sides by -1, we get:
3/k = B.

23.45 inches fabric was used on a headband and 9.64 inches fabric was used on a wristband for each player.
No. of players = 29
No. of coaches = 4
Total fabric used for headbands = 773.85 inches
Total no. of people for headbands = 29 + 4
= 33
Fabric used for headband for 1 person = 773.85/33
= 23.45 inches
Total fabric used for wristbands = 279.56 inches
Total no. of people for wristbands = 29
Fabric used for headband for 1 person = 279.56/29

Step-by-step explanation:
⇒ 3
Odds for : 1/6Odds against : 5/6⇒ 2
Odds for : 1/6Odds against : 5/6⇒ 6
Odds for : 1/6Odds against : 5/6⇒ 4
Odds for : 1/6Odds against : 5/6a farmer has two types of milk, one that is 28% butterfat and another that is 16% butterfat. how many gallons of each should be combined to create a 60-gallon mixture that is 22.5% butterfat?
30 gallons of 28% butterfat and 30 gallons of 16% butterfat should be combined to create a 60-gallon mixture that is 22 % butterfat.
Let x gallon of 28% butterfat mixed with the y gallon of 16% butterfat to obtain 60 gallons of 22.5% butterfat,
⇒ x + y = 60 ⇒ x = 60 - y ----(1),
Quantity of butterfat in x gallon + quantity of butterfat in y gallon = total quantity of butterfat,
⇒ 28% of x + 16% of y = 22% of 60
⇒ 0.28x + 0.16y = 0.22 × 60
⇒ 0.28x + 0.16y = 13.2
⇒ 28x + 16y = 1320
⇒ 14x + 8y = 660
From equation (1),
14(60-y) + 8y = 660
840 - 14y + 8y = 660
6y = 180
y = 30
Again from equation (1),
x = 60 - y
= 60 - 30
= 30
Hence, 30 gallons of 28% butterfat and 30 gallons of 16% butterfat are combined to create a 60-gallon mixture that is 22%

Step-by-step explanation:
The percentage refers to the per hundred or hundredths and is ended with the symbol %. By dividing two amounts, ratios and percentages are both used to compare the two amounts.
The formula for finding the percentage is to divide the value by the total value and then multiply the value by 100.percentage = ( given value / total value ) x 100so,
The given value is 18 people.The total value is 50 people.percentage = ( 18 / 50 ) x 100 = ( 0.36 ) X 100 = 36 %Therefore the percentage of 18 people out of 50 people is 36 %.

Please solve this ratio and proportion

b) The ratio of the cement to sand is 1:3 so if you have 24 buckets of sand, that means you need 24/3 = 8 buckets of cement.
c) The ratio at which the money is to be distributed is 5:2:4:3. So the money is to be partitioned into 14 (=5+2+4+3) parts so that A get (5/14) of the money, B gets (2/14), C gets (4/14) and D gets (3/14). If C gets R1000 more than D then we can write
\(C = D + 1000 \Rightarrow \frac{4}{14}M = \frac{3}{14}M + 1000\)
Solving for M, which is the total sum of money, we get
\(\frac{1}{14}M = 1000 \Rightarrow M =R14000\)
Now that we know how much money is involved we can now solve how much money B gets:

Step-by-step explanation:
Thomas obtained a bank loan of k10 000 from BSP bank.He repays the money with 36% interest in one year.Calculate his installment payment he pays in one fortnight?
Thomas' installment payment that he pays in one fortnight is approximately k523.08.
To calculate Thomas' installment payment, we need to consider the principal amount (k10,000) and the interest rate (36%).
First, let's calculate the total amount to be repaid at the end of the year, including the interest. The interest is calculated as a percentage of the principal amount:
Interest = Principal × Interest Rate
= k10,000 × 0.36
= k3,600
The total amount to be repaid is the sum of the principal and the interest:
Total Amount = Principal + Interest
= k10,000 + k3,600
= k13,600
Now, we need to calculate the number of fortnights in a year. There are 52 weeks in a year, and since each fortnight consists of two weeks, we have:
Number of Fortnights = 52 weeks / 2
= 26 fortnights
To find the installment payment for each fortnight, we divide the total amount by the number of fortnights:
Installment Payment = Total Amount / Number of Fortnights
= k13,600 / 26
≈ k523.08
Therefore, Thomas' installment payment that he pays in one fortnight is approximately k523.08.
It's important to note that this calculation assumes equal installment payments over the course of the year. Different repayment terms or additional fees may affect the actual installment amount. It's always advisable to consult with the bank or financial institution for accurate information regarding loan repayment.

You are given: (i) The future lifetimes of (40) and (50) are independent. (ii) The survival function for (40) is based on a constant force of mortality, u = 0.05. (iii) The survival function for (50) is So(x) = 1 - x/10 (De Moivre's Law with w=110). Calculate the probability that (50) dies within 10 years and dies after (40). A) Less than .02 B) At least .02 but less than .04 C) At least .04 but less than .06 D) At least .06 but less than .08 E) At least.08 Select one: A. Less than .02 B. At least .02 but less than .04 C. At least.04 but less than 06 D. At least.06 but less than 08 E. At least .08
The probability that (50) dies within 10 years and dies after (40) is at least 0.02 but less than 0.04. So the answer is B. At least .02 but less than .04.
To calculate the probability that (50) dies within 10 years and dies after (40), we need to find the joint probability of the two events happening together.
Let X and Y be the future lifetimes of (40) and (50), respectively. We want to find P(Y≤10 and X<Y). Using the Law of Total Probability, we can write:
P(Y≤10 and X<Y) = ∫P(Y≤10 and X<Y|X=t) fX(t)dt
where fX(t) is the probability density function of X.
Since the force of mortality for (40) is constant, the probability density function for X is given by:
f X (t)=ue −ut
where u=0.05.
For (50), we have the survival function S(y) = 1 - y/10. So, the probability density function for Y is:
fY(y) = S'(y) = 1/10
Now, we can substitute these expressions into the integral and simplify:
P(Y≤10 and X<Y) = ∫P(Y≤10 and X<Y|X=t) fX(t)dt
= ∫∫P(Y≤10 and X<Y|X=t) fY(y)fX(t)dydt
= ∫∫P(Y≤10 and t<Y) (1/10)(0.05)e^(-0.05t)dydt
= (1/10)∫e^(-0.05t) ∫1≤y≤10 e^(0.1y) dydt
= (1/10)∫e^(-0.05t) (e - e^(-t/10)) dt
Evaluating this integral, we get:
P(Y≤10 and X<Y) ≈ 0.0286
