Jake is 3 years younger than his brother, Chris. If Chris is c years old, which expression can be used to find Jake's age?

The given quadratic equation gives the parameters of the shape of the

graph of the equation.

Reasons:

The given function is n(t) = -2.82·t² + 25.74·t + 60.87

by analyzing the above function, we have;

At t = 0

n(0) = -2.82 × 0² + 25.74 × 0 + 60.87 = 60.87

Which gives;

\(\displaystyle t = -\frac{25.74}{2 \times (-2.82)} \approx 4.564\)

The maximum value of the function is therefore;

n(4.564) = -2.82 × 4.564² + 25.74 × 4.564 + 60.87 ≈ 119.61

The characteristics of the equation are;

Initial value of equation = 60.87

t-coordinate of the maximum point, t ≈ 4.564

Maximum value of the of the function = 119.61

By comparing with the given graphs, we have;

Therefore, the graph that will most likely be associated with the model is; graph B.

Each transformation affects the shape and position of the graph. It is important to carefully consider the order of the transformations and their impact on the equation.

1. Horizontal Shift (c):
If there is a horizontal shift, the equation becomes y = (x - c)^3.
For example, if there is a shift of 2 units to the right, the equation would be y = (x - 2)^3.

2. Vertical Shift (d):
If there is a vertical shift, the equation becomes y = x^3 + d.
For example, if there is a shift of 3 units upwards, the equation would be y = x^3 + 3.

3. Vertical Stretch (a):
If there is a vertical stretch or compression, the equation becomes y = a * x^3.
For example, if there is a vertical stretch by a factor of 2, the equation would be y = 2 * x^3.

4. Reflection (along the x-axis):
If there is a reflection along the x-axis, the equation becomes y = -x^3.
This flips the graph of the original function upside down.

5. Reflection (along the y-axis):
If there is a reflection along the y-axis, the equation becomes y = (-x)^3.
This mirrors the graph of the original function.

6. Combined Transformations:
If there are multiple transformations, we can apply them in the order they are given. For example, if there is a vertical stretch by a factor of 2 and a horizontal shift of 3 units to the right, the equation would be y = 2 * (x - 3)^3.

Remember, each transformation affects the shape and position of the graph. It is important to carefully consider the order of the transformations and their impact on the equation.

Step-by-step explanation:

when there are two negetive numbers you add them not subtract

Step-by-step explanation:

the distance between 2 points on a coordinate system creates a right-angled triangle.

the distance is the Hypotenuse (the side opposite of the 90° angle). and the x- and y- coordinate differences are the legs.

then Pythagoras applies

c² = a² + b²

c being the Hypotenuse, a and b being the legs.

so,

distance² = (xd - xf)² + (yd - yf)²

5² = (-7 - x)² + (-2 - 2)² = 49 + 14x + x² + 16

25 = x² + 14x + 65

x² + 14x + 40 = 0

the general solution to such a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (-14 ± sqrt(14² - 4×1×40))/(2×1) =

= (-14 ± sqrt(196 - 160))/2 =

= (-14 ± sqrt(36))/2 = (-14 ± 6)/2 = -7 ± 3

x1 = -7 + 3 = -4

x2 = -7 - 3 = -10

It would take the first pipe alone approximately 83.33 minutes to fill the cistern.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's denote the rate at which the first pipe can fill the cistern as r1, and the rate at which the second pipe can fill the cistern as r2. We want to find the time it takes for the second pipe to fill the cistern alone, which we can denote as t.

We can start by using the fact that the cistern can be filled in 10 minutes by both pipes running together. This means that the combined rate at which the two pipes can fill the cistern is:

r1 + r2 = 1/10

We can also use the fact that the cistern can be filled in 25 minutes by the second pipe alone. This means that the rate at which the second pipe can fill the cistern is:

r2 = 1/25

We can now substitute the value of r2 into the first equation and solve for r1:

r1 + 1/25 = 1/10

r1 = 1/10 - 1/25

r1 = 3/250

This means that the rate at which the first pipe can fill the cistern alone is 3/250. We can now use this rate to solve for the time it takes for the first pipe to fill the cistern alone:

3/250 * t = 1

t = 250/3

t ≈ 83.33 minutes

Therefore, it would take the first pipe alone approximately 83.33 minutes to fill the cistern.

Answer:

The true statement is AB > CA > BC ⇒ D

Step-by-step explanation:

In any triangle, the longest side in length is the opposite to the greatest angle in the measure, and the shortest side in length is opposite to the smallest angle in the measure.

Let us solve the question

∵ ABC is a triangle

∵ m∠A = 36°

∵ m∠B = 45°

∵ m∠C = 99°

→ That means C is the greatest angle and A is the smallest angle

∴ ∠C is the greatest angle and ∠A is the smallest angle

∴ The arrange of the measures of the angles is m∠C > m∠B > m∠A

∵ AB is the opposite side of ∠C

∴ AB is the longest side

∵ BC is the opposite side of ∠A

∴ BC is the shortest side

∵ CA is the opposite side of ∠B

∴ The arrange of the lengths of the sides is AB > CA > BC

∴ The true statement is AB > CA > BC

The new perimeter is 127.2 inches if it is multiplied by 19.

What do you mean by the are and perimeter of the square ?

The area of a square is calculated by squaring the length of one of its sides. If the area of a square is multiplied by a factor, the length of the sides will be multiplied by the square root of that factor. One way to express the concept of perimeter for a square is to state that it is the total distance around the outer boundary of the shape, which is equal to the sum of the lengths of all four sides.

Determining the the value of perimeter :

The area of the square is \(7.3 \times 7.3 = 53.29\) square inches.

If this area is multiplied by 19, the new area will be 1012.51 square inches.

To find the new side length of the square, we take the square root of the new area:

\(\sqrt{1012.51} = 31.8\) (rounded to one decimal place)

Therefore, the new side length of the square is 31.8 inches.

To find the new perimeter, we multiply the new side length by 4:

\(31.8 \times 4 = 127.2\)inches

So the new perimeter is 127.2 inches.

To summarize, when the area of the square with side length 7.3 inches is multiplied by 19, the perimeter is multiplied by the square root of 19, which is approximately 4.36. The new perimeter is 127.2 inches.

Since there is only one 8-seat table, it is possible to create an inequality and determine that the number of 2-seat tables is x ≤ 21, as explained below.

An inequality is a statement in mathematics that compares two values, showing that they are not equal. Inequalities use mathematical symbols such as "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to), to indicate the relationship between the two values being compared.

Let's assume that there are 'x' 2-seat tables in the restaurant. Each 2-seat table can accommodate 2 people, and the large 8-seat table can accommodate 8 people. We are told that there are tables to fit at least 50 people in the restaurant. Therefore, we can write the following inequality to represent the possible number of 2-seat tables:

2x + 8 ≤ 50

This inequality means that the total number of people that can be accommodated by the 2-seat tables (2x) and the large 8-seat table (8) must be less than or equal to 50. It is possible to simplify the inequality as seen below:

2x ≤ 42

x ≤ 21

Therefore, the possible number of 2-seat tables in the restaurant is any whole number less than or equal to 21.

b). The surface area of the prism is equal to 184.86cm²

a) By observation, the trianglular prism have three rectangles such that when stretched out will be a large rectangle with 16.25cm length and 10cm width, having two identical right triangles which the longest side Wil be the hypotenuse, while the base is 5.2cm and height is 4.3cm

b). area of the large rectangle = 16.25cm × 10cm

area of the large rectangle = 162.5 cm²

area of the identical right triangles = 2(1/2 × 5.2cm × 4.3cm)

area of the identical right triangles = 5.2cm × 4.3cm

area of the identical right triangles = 22.36 cm²

surface area of the trianglular prism = 162.5 cm² + 22.36 cm²

surface area of the trianglular prism = 184.86 cm².

Therefore, the net of the trianglular prism is a rectangle with dimension of 16.25cm length by 10cm width, with identical two right triangles on both sides with hypotenuse of 6.75cm, 5.2cm base and 4.3cm height. The surface area of the prism is equal to 184.86cm²
