The plane was flying at a height of 706.32 m .

The fundamentals of an object's motion, such as its position, velocity, or acceleration over time, are defined by kinematics equations of motion. An object's motion in one, two, and three dimensions is determined by these three equations of motion. One of three equations of motion can be used to calculate components like displacement (s), velocity (initial and final), time (t), and acceleration (a). The following are the three motion equations:

Initial formula: v = u + at

The second formula is s = ut + 0.5at2.

The third formula is v2 = u2 + 2as.

Let t stand for the package's flight time, s for the plane's altitude, and u for the packet's initial vertical velocity since it is simply dropped.

Given: t = 12 seconds for the delivery to arrive to the ground

With t = 12 and u = 0 in the second equation of motion, we so obtain

s = 0*t + 0.5*9.81*12² = 706.32 m

If a store advertised a sale that gave customers a 1/4 off the original price of $825.00 he also wanted to use a coupon for 1/5 off the sale price, then he paid $453.75

The original price of the item = $825

The off offered by the store = 1/4

The off offered by the coupon = 1/5

Total off = 1/4 + 1/5

= 9/20

Then the selling price = The original price of the item - The original price of the item× (9/20)

= 825 - 825×9/20

= 825-371.25

= $453.75

Hence, if a store advertised a sale that gave customers a 1/4 off the original price of $825.00 he also wanted to use a coupon for 1/5 off the sale price, then he paid $453.75

The number line (C) represents the solution to the inequality -0.96 ≥ 0.3x option (C) is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

The inequality is:

Let the number is x:

-0.96 ≥ 0.3x

0.3x ≤  -0.96

x ≤ -0.96 /0.3

x ≤ -3.2

x ∈ (-∞, -3.2]

As we know, the number line can be defined as the representation of the numbers on a straight line that goes infinitely on both sides.

The values of x and y in the system of equations are x = 1 and y = 2

Linear equations are equations that have constant average rates of change.

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

4x + 3y = 10

y - x = 1

Make y the subject in the second equation, by adding x to both sides of the equation

y - x + x = x + 1

This gives

y = x + 1

Substitute y = x + 1 in 4x + 3y = 10

4x + 3(x + 1) = 10

4x + 3x + 3 = 10

Evaluate the like terms

7x = 7

This gives

x = 1

Substitute x = 1 in y = x + 1

y = 1 + 1

Evaluate

y = 2

Hence, the solution for the system of linear equations 4x + 3y = 10 and y - x = 1 are x = 1 and y = 2

Solution :-

2x - 9y = -1

2x = 9y - 1

x = 9y - 1 / 2 _________ (1)

Now, substitute it here!

-4x - 3y = - 19

-4 (9y - 1 /2) - 3y = -19

(-36y + 4 - 6y / 2) = -19

(-42y + 4 / 2) = -19

-42y + 4 = -38

-42y = -38 - 4

-42y = -42

y = 1

Value of x :

Substituting the value of y that is 1 in this equation. x = 9y - 1 / 2

The equation of line passing through point (6,0) and having a slope of -5/6 is y = -(5/6)x + 5

The formula for equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point: (6,0)

First, we determine the y-intercept by substituting the given values into the equation of line formula and solve for b.

y = mx + b

0 = (-5/6)6 + b

0 = -5 + b

b = 5

Now that the values of slope m ( -5/6 ) and y-intercept b ( 5 ) is known, plug these into y = mx + b to determine the equation of the line.

y = mx + b

y = (-5/6)x + 5

y = -(5/6)x + 5

Therefore, the linear equation of the line is y = -(5/6)x + 5.

4 - 4n = 12 ( subtract 4 from both sides )

- 4n = 8 ( divide both sides by - 4 )

The area of the rectangle will be 512[tex]cm^{2}[/tex] .

let the longer side of the rectangle be "l" and the shorter side of the rectangle be "b".

Hence, the perimeter of rectangle = 2(l+b)

we are given the perimeter =96cm

thus, 2(l+b)=96

l+b = 96/2

l+b =48

also, we are given the condition that the longer side of the rectangle is two times the length of the Shorter side.

Thus, l=2b, substituting this in l+b=48 we get

2b+b=48

3b=48

b=48/3

b=16cm, now substituting this in l=2b,

l=2(16)

l=32cm

area of the rectangle = length x breadth

=l x b

=32 x 16

= 512[tex]cm^{2}[/tex]

His grades improved by 2.2 %

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.

Given: Original grades = 75, 85, 90, 90,

100, 75, 80, 100, 90.

And grades after the retake = 85, 85, 100, 90, 100, 85, 80, 100, 90.

So the sum of the original scores = 785.

Thus the percentage can be calculated by 785/ total marks

= 785/ 900 × 100 = 87.2 %

And the sum of the grades after retake= 805

Thus the percentage will become = 805/900 × 100 = 89.4 %

The mean of the first set is 87 and the mean of the second set is 89.

The range of the function  f(x) = |x| − 5 is −5 ≤ y < ∞.

Given the function is  f(x) = |x| − 5

we know the domain is (−∞,∞)

therefore from the domain we calculate the range as:

−5 ≤ y < ∞.

A function's domain and range are its constituent parts. A function's range is its potential output, whereas its domain is the set of all possible input values.

All real numbers are defined by the function y=|ax+b|. Consequently, the set of all real numbers is the domain of the absolute value function. Every time a number has an absolute value, it has a positive value. The range of an absolute value function with the form y= |ax+b| is hence y R | y 0.
