The equation of the line is y = -4x - 15.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The line y = m(1)x + c is perpendicular to y = x/4 - 2.

This means,

y = (1/4)x - 2 is in the form of y = m(2)x + c

So,

m(1) x m(2) = -1

m(1) = -1 / (1/4)

m(1) = -4

Now,

The line intersects (4, -1).

So,

y = -4x + c

-1 = -4(4) + c

-1 = -16 + c

c = - + 16

c = -15

Thus,

The equation of the line perpendicular to y = x/4 - 2 is y = -4x - 15.

Volume of cone =  100.48 cubic units.     and  The Volume of cylinder= 301.44 cubic units.

One of the fundamental three-dimensional forms in geometry is the cylinder, which has two distant, parallel circular bases. At a certain distance from the centre, a curved surface connects the two circular bases. The axis of the cylinder is the line segment connecting the centres of two circular bases. The distance between the two circular bases is used to define the cylinder's height. An LPG gas cylinder is one of the genuine examples of a cylinder. The cylinder is a three-dimensional object with two essential properties: surface area and volume. The whole surface area of the cylinder is composed of the combined curved surface area of the cylinder plus the areas of the two circular bases.

A cone has a radius of 4 units and a height of 6 units.

Volume of cone =  [tex]V=\frac{1}{3}\pi r^2h[/tex]

Where, r=4 and h=6

Volume of cone =  [tex]V=\frac{1}{3}\pi 4^2\times 6[/tex]

Volume of cone =  100.48 cubic units.                

If a cylinder has the same radius and the same height as the cone.

Volume of cylinder [tex]V=\pi r^2h[/tex]

A. Mean = 71

B. Median = 75

C. Mode = 0

D. Mean is used to represent data, because mean measures central tendency.

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data set is called the mode.

We have the Data set: 35, 42, 43, 51, 55, 57, 62, 66, 68, 69, 74, 75, 76, 77, 78, 79 , 82, 84, 86, 88, 93, 94, 101

So, Mean = average

                = sum of all numbers / total number of values .

                 = 1635 / 23

                 = 71.08

                 = 71

and, Median = middle term = 12th term = 75

lastly, Mode = Most repeated term or term that has high frequency.

Here no terms are repeating so mode = 0

BIDMAS is an order of operation.

Multiply first or the indices? We can solve it with order of operations.

Here we go ↓↓

B = Brackets

I = Indices (³ ²)

D = Division

M = Multiplication

A = Addition

S = Subtraction

NOTE = Multiply or divide first? We do it from left to right

NOTE = Addition or Subtraction? We also do it from left to write in an equation.

Step 1 :

We replace all the letters with the given value, this make it :

[tex]1/4 (-4^{3} + 10^{2} )[/tex]=?

Step 2 :

Now, according to the rules, we do the numbers in the brackets first, now, in the brackets, there are indices, so we do those.

Which makes it :

1/4(-64+100)= ?

Step 3 :

Now we add the integers inside the brackets, remember, whenever the equation is like this, it is telling us it is a multiplication, here, it will be 1/4 x (-64+100) . In algebra, we don't use the × sign as it can be misinterpreted as [tex]x[/tex] .

1/4 (-64+100 = 36)

1/4 (36)

     =

The bag that contains​ pennies, nickels,​ dimes, and quarters have the total amount of 5.26 dollars.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A bag contains 50 coins

Now, Number of pennies = 14% of 50

                               = 0.14 × 50

                               = 7 pennies

and, Number of dimes  = 40% of 50

                             = 0.40 × 50

                             = 20 dimes

Number of nickels = 6 more than pennies

                              = 6 + 7

                             = 13 nickles

Number of quarters = Rest of the coins

                               = 50 - (7 + 20 + 13)

                               = 50 - 40

                              = 10 quarters

As we know,

1 penny = 0.01 dollar

7 pennies = 0.01 ×7  = 0.07 dollar

1 dime = 0.10 dollar

20 dimes = 0.10 × 20 = 2.00 dollar

1 nickel = 0.05 dollar

13 nickel = 0.05 × 13 = 0.65 dollar

1 quarter = 0.25 dollar

10 quarter = 0.25 × 10 = 2.50 dollars

Total value of the coins in the bag = 0.07 + 2.00 + 0.65 + 2.50

We can notice that the expression has an even number of terms, and the first and last term are perfect squares, which suggests that it might be possible to write the expression as the square of a binomial.

Let's try to write the expression in the form of (a + b)²:

(a + b)² = a² + 2ab + b²

If we set a = m and b = 1/m, we get:

(a + b)² = m² + 2(m)(1/m) + (1/m)² = m² + 2 + 1/m²

Comparing this with the given expression, we see that it is the same as the given expression with 2 added to it.

Therefore, to make the given expression a perfect square, we need to add 2 to it.

So, the term to be inserted is 2.

The expression m² +........+ 1/m² can be written as (m + 1/m)² - 2.

The population after 5 years will be approximately 8.45 billion.

The exponential equation to model the world population (in billions) after t years is P(t) = 8(1.011)^t, where P(t) is the population in billions and t is the number of years after 2022.

To write this equation, we need to use the information provided in the question. The initial population in 2022 is 8 billion, so this is our starting value. The growth rate is 1.1% per year, which can be written as 1.011 in decimal form.

We can use the formula for exponential growth, P(t) = P0(1 + r)^t, where P0 is the initial population, r is the growth rate, and t is the number of years.

Substituting the values for P0 and r into the equation, we get:

P(t) = 8(1.011)^t

This equation can be used to find the population after t years.

For example, to find the population after 5 years, we can substitute t = 5 into the equation and get:
