The amount of money you must pay at the gas station could be represented using the variables y = price in dollars, x = gas in gallons, and a proportionality constant, k: y = kx.

Mrs. Tenon has spent $5 on 25 party favours.

Equation form of proportional relationships is written as y=kx.

If you substitute $5 for y and $25 for x in the formula for the proportional relationship above, you can find the value of the proportionality constant, or k.

$5=k(25)\sk=$5/25\s=0.2

0.2 is the proportionality constant. Thus, each party favour costs $0.20.

Let's say there are r party favours and the cost is c. c=0.2r

In the equation above, 40 should be substituted for r to get the price of 40 party favours: c=0.2 (60) = 12.00.

As a result, the cost for 40 guests is $ 8.00, and the cost for 60 party favours is $ 12.00.

The rule for g is g(x) = (-2x - 10)(√(x² - 2)) for the function g(x) = -2f(x+5).

One way to think of a function is as a rule that assigns or maps each member of a set, x, to the same value, y, known as its image.

x → Function → y

Functions are frequently denoted by a letter, such as f, g, or h. F(x) = x2+ 5 is the formula for the function that squares a number and adds a 3. A function's impact on specific values can be demonstrated using the same idea.

Given that  f(x) =  √(x² - 2)

And g(x) = -2f(x+5)

Substitute the function f(x) =  √(x² - 2) in g(x) = -2f(x+5)

g(x) = -2(√(x² - 2))(x+5)

g(x) = (-2x - 10)(√(x² - 2))

Thus, the rule for g is g(x) = (-2x - 10)(√(x² - 2)) for the function g(x) = -2f(x+5).

3x² is a second-degree polynomial, also known as a quadratic equation.

A polynomial is a mathematical expression that consists of constants, variables, and exponents. This polynomial can be represented as an equation in the form of ax^2 + bx + c, where a, b, and c are constants, and x is an unknown. In this case, a = 3, b = 0, and c = 0. In this case, the polynomial is 3x², which contains one constant (3) and one variable (x) with an exponent of 2. To calculate the value of this polynomial, we can substitute a value for x and then solve. For example, if x=2, then 3x² = 3x2 = 3(2)2 = 3(4) = 12.

Answer: 14

Step-by-step explanation:

Que knows that the required hypotenuse of the given right triangle is 18.35 units from the Pythagorean theorem.

To determine the undiscovered side of a right-angled triangle, utilize the Pythagoras theorem.

The hypotenuse (third side) of a right-angled triangle, for instance, can be determined using the formula c2 = a2 + b2, where 'c' stands for the hypotenuse and 'a' and 'b' are the two legs.

So, we have:

Height of 6 and bas of 9 units of the right triangle.

Pythagorean formula:

c=√a²+b²

Now, insert values and calculate as follows:

c = √a²+b²

c = √9²+16²

c = 18.35 units

The expression of an exponential function f that has a slope of 12 of a line from the point (0, f(0)) to the point (2, f(2)) is the exponential function;

An exponential function is a function that includes the argument as an exponent, index or power of a constant.

The points on the function are; (0, f(0)), and (2, f(2))

The required slope between the points x = 0, and x = 2 is 12

Therefore;

(f(2) - f(0))/(2 - 0) = 12

f(2) - f(0) = 12 × (2 - 0) = 24

The exponential function can be presented in the form;  f(x) = a·bˣ

When x = 0, we get; f(0) = a·b⁰ = a

When x = 2, we get; f(2) = a·b²

f(2) - f(0) = a·b² - a = 24

a·(b² - 1) = 24

Each measure of the angle when the total measure of the angles is (n−2)·180° and n is 8 will be 235°.

From the information, the total measure of the angles is (n−2)·180°, where n=8. The term regular means all interior angle measures are the same.

It should be noted that in Mathematics, the value of the sum of angles is Illustrated in this case. We can determine each angle measure from the total angle measure thus:

(n - 2) × 180

n = 8

It should be noted that n in this case simply means the number of sides
