Kyles's monthly repayment on the television based on hire purchase agreement is R229

The monthly repayment is the amount paid monthly with interest on a particular loan or to recover from debt.

From the given information:

Thus

principal amount left to be repaid = 5600 - 840 = 4760

Using the formula:

[tex]\mathbf{M=\dfrac{P( \dfrac{r}{12}) (1+\dfrac{r}{12})^n }{(1+\dfrac{r}{12})^n - 1}}[/tex]

Answer:

  (a)  This function represents a direct variation because it passes through the origin and has a constant rate of change of $5 per hour.

Step-by-step explanation:

The equation of direct variation is ...

  y = kx

for some constant k. Here, we have x in hours and y in dollars. We can see if k is constant for the values given in the table.

__

Solving the direct variation formula for k, we have ...

  k = y/x

Using the table values, we can see if this is constant:

  k = dollars/hour = 10/2 = 20/4 = 30/6 = 40/8 = 5

The "rate of change" is constant at $5 per hour.

The function represents direct variation because it passes through the origin and has a constant rate of change of $5 per hour.

Th amount of money that Diana is left with is $8,430.23.

The first step is to determine the interest earned in the first year and the total amount that was made in the 2 years.

The formula used to determine the future value with monthly compounding is:

P(1 + r)^( n x m)

Where:

Total amount made in 2 years = $8000 x ( 1 + 5% / 12)^(12 x 2) = 8839.53

Interest earned in the first year = [ $8000 x ( 1 + 5% / 12)^(12) ] - 8000 = $409.29

Amount she is left with =  8839.53 - $409.29 = $8430.23

The probability that a student is a female or major in civil engineering is 62%

Let A represent Female and B represents civil engineering.

So, we have:

P(A) = 49%

P(B) = 21%

P(A and B) = 8%

The required probability is calculated as:

P(A or B) = P(A) + P(B) - P(A and B)

This gives

P(A or B) = 49% + 21% - 8%

Evaluate

P(A or B) = 62%

Hence, the probability that a student is a female or major in civil engineering is 62%

Answer:

The airplane reaches its maximum height of 74 feet in 14 seconds.

Step-by-step explanation:

The easiest thing to do here is to plug in the two numbers given in the answer choices. Finding the height at 14 seconds and the height after 74 seconds is straightforward from here.

h (14) = -(14-14)²+ 74

h (14) = 0 + 74

h (14) = 74

h (74) = -(74-14)² + 74

h (74) = -(60)² + 74

h (74) = -3600 + 74

h (74) = -3,526

Now, we know that a height of an airplane won't be negative, as the height below the ground cannot be reached.

because our equation includes -(t-14)², any number greater than 14 will be a larger negative than 0--setting the height to an impossible number.

{However, we add +74 feet, so our t-14 could be any number that is less than 74 when squared (after first subtracting 14 from the number). Numbers like 15, (resulting in subtracting 1 from 74), 16 (resulting in -4 from 74), 17 (74-9), 18 (74-16), 19 (74-25), 20 (74-36), 21 (74-49), 22 (74-64) are still above the minimum input}

{So, our t could be up to 22, and any number above this maximum limit, such as 23, result in a height of 0}

for example: -(23-14)²  + 74

-(9)² = -81

-81 + 74 = -7

All numbers below 14, which would end in an eventual negative outcome  [ -(x)² = negative if x < 0 ]

are greater than a t of 14.

-(13-14)² = -1

; showing that t = 14 is our maximum height

(remember that if you have -(x)² you get the negative version of x² [pemdas. the negative outside of the parenthesis is equivalent to multiplying the parenthesis by -1. (E)xponents comes before (M)ultiplication].)

The total length of the ribbon is 52 m.

Aleena initially cuts 3/8 of the ribbon, i.e. a length of (3/8)x.

1 - (3/8)x = (5/8)x.

i.e. (4/5) * (5/8)x = (20/40)x = (1/2)x

(3/8)x + (1/2)x = (3/8)x + (4/8)x = (7/8)x

That means  1 - (7/8)x = (1/8)x remains, and that is a length of 6.5 m.

1/8 of what number is 6.5?

Let y = the unknown number.

(1/8)y = 6.5

Multiply both sides of the equation by 8 to clear the fraction.
