Answer:

Answers below

Step-by-step explanation:

a)solving for f(2)

f(2)= 5(2) - 3 (input the given value for the letter x)

f(2) = 10 -3 (multiply your inputed value with whatever is infront of it)

f(2) = 7 (Connect simmilar terms)

b) solving for f(32)

remember to follow the steps from above

f(32) = 5(32) - 3

f(32) = 160 -3

f(32) = 157

c) solving for f(-8)

we are going to end up on the negatives and thats okay. Not all answers have to be positive

f(-8) = 5(-8) -3

f(-8) = -40 -3

f(-8) = -43

The sine, cosine, and tangent are the three fundamental trigonometry operations. The cotangent, secant, and cosecant functions are derived from these three basic functions.

Numerous applications of trigonometry and its operations can be found in daily life. For instance, it is used in astronomy to determine how far away nearby stars are, in geography to determine the distance between landmarks, and in the satellite navigation system.

Here,

The three basic categories of trigonometric functions are sine, cosine, and tangent.

And

from the primary functions, one can derive the three cotangent, secant, and cosecant functions.

from the given option the slope of the line -5/2 is shown by the equation   [tex]$y=-\frac{5}{2} x-4$[/tex]that is option B).

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). Measured by slope, a line's steepness. The slope increases in steepness as it gets larger. It becomes flatter the smaller the slope. Along with indicating whether a line is going up, down, horizontal, or vertical, slope also indicates the direction of the line.

From the given option the slope of the line [tex]$-5 / 2$[/tex] is shown by the equation [tex]$y=\frac{2}{5} x[/tex] that is option[tex]$\mathbf{B}$[/tex] ) and this can be determined by using the slop intercept form.

Given :

Equation -[tex]$y=\frac{2}{5} x-1$[/tex]

First, determine the slope of the given line by using the slope-intercept form. The slope-intercept is given by the equation:

[tex]$$y=m x+c$$[/tex]

Now, compare equation (1) with the above equation.

[tex]& \mathrm{m}_1=\frac{2}{5} \\[/tex]

[tex]& \mathrm{c}=-1[/tex]

For a line to be perpendicular to the other line the product of the slope of both the line is equal to -1, that is:

Linear equation: If the maximum power of the variable/symbol in an equation is one, then the equation is called a linear equation.

An example of a linear equation is x + y = 10.

Definition of Degree: The maximum power in an equation of variable is known as a degree.

So, the degree of a linear equation is 1.

Linear equations are equations based on the first order. The linear equations are explained for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e., only one variable), then it is known as a linear equation in 1 variable.

If a linear equation can have more than one variable. If the linear equation has two or more two variables, then it is called a linear equation with two variables, and so on.

Answer and Explanation: To get the two terms on the right to combine into one term, we need the denominators of both terms to be the same. To do this we can plug in x+3 for the bottom left denominator and x-4 for the bottom right denominator. This makes both denominators (x+3)(x-4).

The numerators of both terms on the right just have to add up to 3x-2. One way we could do this is to the right one as 3x and the other as -2 or vice versa.

(x+3)(x-4) simplifies to x^2-x-12 which is why the denominator of the term on the left is that.

Probability is used to determine how likely it is that a random event would happen. The probability that a random event occurs lie between 0 and 1.  The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

Answer:

Step-by-step explanation:

8) a) In a parallelogram, opposite sides are equal and parallel.

               BC = AD

         12x - 1 = x  + 21

         12x      = x + 21  + 1

              12x = x + 22

         12x - x = 22

                11x = 22

                  x = 22 ÷ 11

                 x = 2

AD = x + 21

     = 2 + 21

AD = 23

To graph the ellipse, connects (2, 2), (11, -8), (2, -18) and (-7, -8) with  smooth curve.

What is ellipse?

An ellipse in mathematics is a plane curve that has two focal points and is such that the sum of the two distances from any point on the curve to the focal points is a constant. It generalizes a circle, a special kind of ellipse in which the two focal points coincide.

Given:

The equation of ellipse is,

[tex]\frac{(x-2)^2}{81}+(\frac{(y+8)^2}{100}=1[/tex]

Since, the general form of ellipse is,

[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]

where,

(h, k) is the center of ellipse

a is the minor axis

b is the major axis.

Here (h, k) = (2, -8) is the center of the ellipse.

9 is the minor axis and 10 is the major axis of the ellipse.

Also the graph of ellipse connects (2, 2), (11, -8), (2, -18) and (-7, -8) with  smooth curve.

Hence,  the center of the ellipse is (2, -8).

The endpoints of the major axis are 10 units from the center.

The endpoints of the minor axis are 9 units from the center.

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 4(for every one boy there are 3 girls) 1 / 4 are boys and 4 / 5 are girls. 0.20 are boys (by dividing 1 by 5). It can also be defined as the size, number, or amount of one thing or group as compared to the size, number, or amount of another.

The cost of 2.5kg of potatoes is £1.40

Therefore the cost of 1kg potatoe = 1.40/2.5 = £0.56

This means that the cost of 4.25 kg = 0.56× 4.25

To find the percent full of the popcorn box, we need to divide the volume of popcorn in the box by the total volume of the box, and then multiply by 100 to convert the result to a percentage.

First we need to find the total volume of the box:

V = l x w x h

V = (2 1/2 in x 2 3/4 in x 5 in) = (5/2 in x 7/4 in x 5 in) = (35/4 in^3) = 8.75 in^3

Now we can calculate the percent full:

percent = (26 in^3 / 8.75 in^3) x 100 = 2.97 x 100 = 297%

The popcorn box is 297% full.

It's worth noting that 297% means that the popcorn box is almost 3 times full
