Answer:
5 weeks
Step-by-step explanation:
the two linear equations are:
sibling (A) and sibling (B)
y = 10x + 25 and y = 5x + 50
where y = mx + c
and x represents the number of weeks
after how many weeks will their savings accounts have the same amount of money i.e. for which value of x will both equations have the same value
inserting the value of x in both equations:
for x = 2.5 A = 50 and B = 62.5
for x = 5 A = 75 and B = 75
for x = 15 A = 175 and B = 125
for x = 75 A = 775 and B = 425
thus, after 5 weeks both siblings A and B will have the same amount of money in their accounts
1. Write a polynomial of degree 3 with zeros
x = 3,x= -4, and x = 5.
The polynomial of degree 3 with zeros at x = 3, x = -4, and x = 5 is P(x) = x^3 - 4x^2 - 17x + 60.
To construct a polynomial of degree 3 with zeros at x = 3, x = -4, and x = 5, we can use the fact that the polynomial can be written as a product of linear factors corresponding to each zero.
The factor corresponding to x = 3 is (x - 3).
The factor corresponding to x = -4 is (x + 4).
The factor corresponding to x = 5 is (x - 5).
To obtain the polynomial, we multiply these factors together:
P(x) = (x - 3)(x + 4)(x - 5)
Expanding this expression gives us:
[tex]P(x) = (x^2 - 3x + 4x - 12)(x - 5)[/tex]
[tex]= (x^2 + x - 12)(x - 5)[/tex]
[tex]= x^3 - 5x^2 + x^2 - 5x - 12x + 60[/tex]

BK plays a game, which assigns a number (Z)that is the continuous random variable with the density function
(z) =1/5,0≤z≤5
0, otherwise.
If the game assigns a number less than or equal to, then he loses 10 dollars, on the other hand, if the game assigns a number larger than, then he will gain 10 dollars. (a) Find the expected profit of the game. (b) Find the variance of the profit. (c) If you were to play this game 10 times, what is the probability that you gain 20 dollars?
(a) The expected profit of the game is $0. (b) The variance of the profit is 0. (c) The probability of gaining $20 in 10 plays is 0.
Answers to the questionsTo solve the given problem, we'll calculate the expected profit, variance of the profit, and the probability of gaining $20 in 10 game plays.
(a) Expected Profit:
To calculate the expected profit, we need to multiply the potential profit or loss with its corresponding probability and sum them up.
Profit (X) = Gain - Loss = $10 - $10 = $0
Probability of gaining: P(X = $0) = P(Z > 5) = 0 (since Z is only defined up to 5)
Expected Profit (E(X)) = $0 * P(X = $0) = $0
(b) Variance of the Profit:
The variance can be calculated using the formula: Var(X) = E(X^2) - (E(X))^2.
In this case, since the profit is always zero, the variance will also be zero.
Variance of the Profit (Var(X)) = 0 - (0)^2 = 0
(c) Probability of Gaining $20 in 10 plays:
Since each play is independent, the probability of gaining $20 in a single play is 0. Since the probability of gaining is 0 for each play, the probability of gaining $20 in 10 plays will also be 0.
Probability of gaining $20 in 10 plays = 0

The box of pancake says that it makes 10 pancakes but sam is able to make 8 pancakes from the ingredient. Here the number 10 represents Theoretical yield.
Here,
Theoretical yield can be defined as the product received from the complete conversion of the limiting reactant in a chemical process.
It is the amount of product resulting from a theoretical chemical reaction and it is not the same as the amount you'll actually get from a reaction in the lab.
Theoretical yield is commonly expressed in terms of grams or moles. the actual yield is the amount of product actually produced by a reaction. Actual yield is usually a smaller quantity because few chemical reactions proceed with 100% efficiency because of loss recovering the product and because other reactions may be occurring that reduce the product. so 10 here is a theoretical yield bot the actual yield.

A soccer player jumps up and heads the ball while it is 7 feet above the ground. If the function
y = -16t squared + 20t + 7 represents this situation, about how long will it take the ball to hit the ground?
Answer:
3.3 seconds
Step-by-step explanation:
To find the time it takes for the ball to hit the ground, we need to solve the equation y = 0, since the ball will be on the ground when its height (y) is zero.
The equation given is:
y = -16t^2 + 20t + 7
Setting y to zero:
0 = -16t^2 + 20t + 7
To solve this quadratic equation, we can either factor it or use the quadratic formula. In this case, factoring may not be straightforward, so let's use the quadratic formula:
t = (-b ± √(b^2 - 4ac)) / (2a)
For our equation, a = -16, b = 20, and c = 7. Substituting these values into the quadratic formula:
t = (-20 ± √(20^2 - 4(-16)(7))) / (2(-16))
t = (-20 ± √(400 + 448)) / (-32)
t = (-20 ± √848) / (-32)
Simplifying further:
t = (-20 ± √(16 * 53)) / (-32)
t = (-20 ± 4√53) / (-32)
Now we have two possible solutions for t:
t1 = (-20 + 4√53) / (-32)
t2 = (-20 - 4√53) / (-32)
Since time cannot be negative in this context, we can disregard the negative solution.
t ≈ (-20 + 4√53) / (-32)
Calculating this value:
t ≈ 3.3 seconds (rounded to one decimal place)
Therefore, it will take approximately 3.3 seconds for the ball to hit the ground.

The height of the given triangle will be 13.416 cm.
Given a right-angle triangle that has a hypotenuse of 14 cm, height of x, and base of 4 cm.
The Pythagorean theorem is a fundamental principle in geometry that establishes a relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Applying the Pythagorean theorem, we can write:
[tex]14^2 = 4^2 + x^2[/tex]
Simplifying the equation:
[tex]196 = 16 + x^2[/tex]
Subtracting 16 from both sides:

The x-value of the solution to the system of equations, we need to solve the given equation and the line represented by the data in the table. Let's begin by examining the first equation, 2x + 4y = 0.
We can rewrite this equation in terms of y:
4y = -2x
y = (-2/4)x
y = (-1/2)x
Now, let's use the data from the table to create a system of equations:
For the first data point (-1, 8):
y = (-1/2)x
8 = (-1/2)(-1)
8 = 1/2
Since 8 is not equal to 1/2, the first data point does not satisfy the equation.
For the second data point (3, -4):
y = (-1/2)x
-4 = (-1/2)(3)
-4 = -3/2
Again, -4 is not equal to -3/2, so the second data point does not satisfy the equation.

What is the minimum amount that a person can be chaped for a cash deposit Mr Khumale deposited R4 550,00 over the counter at Standard Bank (2)
The minimum amount that Mr. Khumalo can be charged for the cash deposit is R99.12.
To calculate the minimum amount charged for a cash deposit over the counter at Standard Bank, we'll use the given information.
The deposit charge includes an initial fee of R10.39, and an additional fee of K1.95 per R100 or part thereof, with a minimum charge of R16.00.
First, we calculate the additional fee based on the deposit amount:
Additional fee = (Deposit amount / 100) x K1.95
For Mr. Khumalo's deposit of R4,550.00:
Additional fee = (4,550.00 / 100) x 1.95
Additional fee = 88.725
Next, we compare the additional fee to the minimum charge of R16.00:
If the additional fee is less than the minimum charge, the minimum charge applies. Otherwise, the additional fee is charged.
Since the additional fee of R88.725 is greater than the minimum charge of R16.00, the additional fee will be charged.
Finally, we add the initial fee and the additional fee to get the total charge:
Total charge = Initial fee + Additional fee
Total charge = R10.39 + R88.725
Total charge = R99.115
Therefore, the minimum amount that Mr. Khumalo can be charged for the cash deposit is R99.12.

=) A shopkeeper, selling an object at a discount of 25% loses Rs. 125. If he allow 10% discount, he gains Rs. 250. Find the marked price and the cost price of the article.
The marked price of the article is approximately Rs. 833.33, and the cost price is Rs. 500.
Let's assume the marked price of the article is M and the cost price is C.
According to the given information:
When the shopkeeper sells the object at a discount of 25%, he incurs a loss of Rs. 125. This means that the selling price (S) is 25% less than the marked price (M) and it is equal to the cost price (C) minus Rs. 125.
S = C - Rs. 125
S = M - 0.25M
C - Rs. 125 = M - 0.25M
When the shopkeeper sells the object at a discount of 10%, he gains Rs. 250. This means that the selling price (S) is 10% less than the marked price (M) and it is equal to the cost price (C) plus Rs. 250.
S = C + Rs. 250
S = M - 0.10M
C + Rs. 250 = M - 0.10M
Now we can solve these two equations simultaneously to find the marked price (M) and the cost price (C) of the article.
C - Rs. 125 = M - 0.25M --> C = 0.75M - Rs. 125 (Equation 1)
C + Rs. 250 = M - 0.10M --> C = 0.90M - Rs. 250 (Equation 2)
Setting Equation 1 equal to Equation 2:
0.75M - Rs. 125 = 0.90M - Rs. 250
Rearranging the equation:
0.90M - 0.75M = Rs. 250 - Rs. 125
0.15M = Rs. 125
M = Rs. 125 / 0.15
M = Rs. 833.33 (approx.)
Substituting the value of M back into Equation 1 to find C:
C = 0.75M - Rs. 125
C = 0.75 * 833.33 - Rs. 125
C = Rs. 625 - Rs. 125
C = Rs. 500
Therefore, the marked price of the article is approximately Rs. 833.33, and the cost price is Rs. 500.

2.2.1 find the order of convergence as h — 0.
The order of convergence of the formula as h approaches 0 is at least 1.
To determine the order of convergence as h approaches 0 for the approximation of f'(z) using the given formula, we need to analyze the behavior of the formula as h becomes smaller.
Let's rewrite the formula in a more structured form for better clarity:
f'(z) ≈ [F(z + 2h) - 8F(z + h) + 8F(z - h) - F(z - 2h)] / (12h)
As h approaches 0, we can rewrite the formula using the limit notation:
f'(z) ≈ lim(h→0) [F(z + 2h) - 8F(z + h) + 8F(z - h) - F(z - 2h)] / (12h)
In this case, we can simplify the limit expression by dividing both the numerator and denominator by h:
f'(z) ≈ lim(h→0) [F(z + 2h)/h - 8F(z + h)/h + 8F(z - h)/h - F(z - 2h)/h] / 12
f'(z) ≈ lim(h→0) [F'(z) - 8F'(z) + 8F'(z) - F'(z)] / 12
f'(z) ≈ lim(h→0) 0 / 12
f'(z) ≈ 0
From this analysis, we see that as h approaches 0, the f'(z) approaches 0. This means that the order of convergence of the given formula is at least 1.

Given that HI is approximately equal to IJ, we can say that m∠H is approximately equal to m∠J.
So, m∠H ≈ m∠J.
We're also given that m∠H = 3x + 10 and m∠I = 6x - 20.
Since m∠H ≈ m∠J, we can equate their expressions:
3x + 10 ≈ 6x - 20.
To solve for x, we can subtract 3x from both sides and add 20 to both sides:
10 + 20 ≈ 6x - 3x.
30 ≈ 3x.
Dividing both sides by 3, we find:
10 ≈ x.
Now that we have the value of x, we can substitute it back into the expressions for m∠H and m∠I:
m∠H = 3x + 10 = 3(10) + 10 = 30 + 10 = 40.
m∠I = 6x - 20 = 6(10) - 20 = 60 - 20 = 40.
Therefore, the measures of angles H, I, and J are:
m∠H = 40 degrees,
m∠I = 40 degrees,
m∠J is approximately equal to m∠H and m∠I, so it is also approximately 40 degrees.

The cosD is √53/9 from the given triangle which is adjacent side by hypotenuse
The triangle DEF is a right triangle
We know that cosine function is a ratio of adjacent side and hypotenuse
The adjacent side of angle D is DE
We have to find the length of DE by using Pythagoras theorem
DE²+EF² =DF²
DE²+28=9²
DE²=81-28
DE²=53
Take square root on both sides
DE=√53
So cosD=√53/9

During one year, the population of a town increased by 2% but during the next year it diminished by 2%. If at the end of the second year the population was 6,25,000, what was the population at the beginning?
Answer:
614,818.71
Step-by-step explanation:
hope it helps
Answer:
6,25,250
Step-by-step explanation:
let initaial population be "x"
after increasing by 2%
x'=x+x*2%
x'=102x/100
x' is decreased by 2% and population reached 625000,so,
625000=102x/100-2%*102x/100
625000=102x/100-51x/2500
625000=2499x/2500
2499x=625000*2500
x=1562500000/2499
x=625250.1
complete population is only counted so,
x=625250
initial population =625250
Clara graphed her reading fluency scores for 6 weeks. 99, 88, 97, 107, 100, 109 What is the median of the scores?
Answer:
99.5
Explanation:
First, you would put the numbers into order from least to greatest.
99, 88, 97, 107, 100, 109
Which would be:
88, 97, 99, 100, 107, 109
Median is the middle of the number line, so you would cross off a number from each side until you find the middle.
99, 100
You would end up with two numbers, which you will have to find the mean of. In order to do so, you need to add them together then divide by 2 because there are 2 numbers.
99 + 100 = 199
199/2 = 99.5
