The equation of line passes through the point (-6, -3) will be;

⇒ y = 5/3x + 7

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-6, -3).

And, The parallel line is,

⇒ 5x - 3y = 9

⇒ y = (5x - 9) / 3

Now,

Since, The equation of line passes through the point (- 6, -3).

So, We need to find the slope of the line.

Since, The slope of the parallel line is same.

Hence, Slope of the line is,

y = 5/3x - 3

m = dy/dx = 5/3

m = 5/3

Thus, The equation of line with slope 5/3 is,

⇒ y - (-3) = 5/3 (x - (-6))

⇒ y + 3 = 5/3 (x + 6)

⇒ y + 3 = 5/3x + 10

⇒ y = 5/3x + 10 - 3

⇒ y = 5/3x + 7

Therefore, The equation of line passes through the point (-6, -3) will be;

⇒ y = 5/3x + 7

She will have run a total of 2.25 racers in 27 racers

From the question, we have the following parameters that can be used in our solution:

Total number of racers = 27 racers

Number of racers in a run = 12 racers

From the above parameter, we can calculate the total number of racers using the following equation

The total number of racers is calculated as

Total number of racers in the run = Total number of racers/Number of racers in a run

Substitute the known values in the above equation

So, we have the following equation

Total number of racers in the run = 27/12

Evaluate the quotient

Total number of racers in the run = 2.25

Hence, the total number of racers in the run is 2.25 racers

The ball must be thrown up at an initial velocity of approximately 24.658 feet per second.

Free fall motion is an uniformly accelerated motion due to gravity. In this question we need to determine the initial velocity of a ball (v), in feet per second, such that the ball reaches a height of 37 feet up. The initial velocity can be found by means of the following equation:

v'² = v² + 2 · g · (h' - h)

Where:

If we know that v' = 0 ft / s, g = - 9.807 ft / s², h = 6 ft and h' = 37 ft, then the minimum initial velocity of the ball is:

v² = v'² - 2 · g · (h' - h)

v = √[v'² - 2 · g · (h' - h)]

v = √[(0 ft /s)² - 2 · (- 9.807 ft / s²) · (37 ft - 6 ft)]

v ≈ 24.658 ft / s

The ball must have an initial velocity of approximately 24.658 feet per second.

Answer:

a) 6.2%
b) £13,687

Step-by-step explanation:

a)

To find the rate of interest, we first find the interest itself.
£7965.00 - £7500.00 = £465.00
Using this, we find the rate of interest in percentage as a fraction of the original loan.

(£7500.00 ÷ £465.0) × 100 = 6.2%

Thus, the rate of interest is 6.2%.

b)
Compound interest is found using the formula
[tex]A = P(1 + \frac{r}{100})^{t}[/tex]
Where

A = final amount

P = initial principal balance

r = interest rate

t = number of time periods elapsed

Thus, with an initial balance of £7500, an interest rate of 6.2% and a time period of 10 years, calculated per annum, we can plug the numbers into the formula, giving us

[tex]A = 7500(1 + \frac{6.2}{100})^{10}[/tex]
   [tex]=[/tex] £13,686.94
   ≈ £13,687 (to nearest £1)

Some things to note: number of time periods elapsed mean the amount of times it is compounded; if the question says compounded quarterly for 3 years, t = 12 as it is compounded 4 times a year for 3 years, giving is 12 time periods. This also applies to monthly, bi-weekly etc.

The correct answer option is options A and D

A rectangle is a quadrilateral having opposing sides parallel and four right angles.

At point (x, y) = (10, 100) the area is maximum.

This means that the area of the rectangle is maximum when width is 10m.

If the width of the rectangle is more than 10m, the area reduces or decreases.

Therefore, the statement Greater width relates to greater area as long as the width is more than 10 m is false.

We know that,

Volume of Great Pyramid of Cheops = Volume of the  pyramid  with the base sides of 280m

Volume of Great Pyramid of Cheops is 1/3×(side of the base)²×(height of the pyramid)

Side of the base is 230 meters.

Height of the pyramid is 147 meters.

Volume of the  pyramid  with the base sides of 280m is 1/3×(side of the base)²×(height of the pyramid)

Side of the base is 280 meters.

Height of the pyramid is h meters.

Volume of Great Pyramid of Cheops = Volume of the  pyramid  with the base sides of 280m

1/3×(230)²×(147)=1/3×(280)²×h

h = 99.1875 meters.

No, Beth is not correct. One of the x-values, 2, corresponds to two y-values.

The equation where y is the price of the ticket with the coupon, and x is the original price of the ticket.

y= 0.55 x.

Given:

A movie theater sends out a coupon for 45% off the price of a ticket. Write an equation for the​ situation, where y is the price of the ticket with the​ coupon, and x is the original price of the ticket.

If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately  pays (y) is  the original price (x) minus a 45% of this price:

y= x -0.45 x

By association: y= (1-0.45) x

and then y= 0.55 x.

The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).

Hence we get the required equation.
