Answer: No, it is not proportional.

Explanation:

We can see that Diego opened an account with $20, meaning that there is going to be a y-intercept of 20 in a graph. Therefore, with a y-intercept of 20 and not zero, we can say that there is not a proportional relationship between and time and amount saved for Diego.

The system is consistent and independent.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have the system of equations:

y = 4x - 4

y = -4x + 4.

Let's take the quotient between both the equations as;

(y/y) = (4x - 4)/(-4x + 4)

1 = (4x - 4)/(-4x + 4)

Solve for x;

1*(-4x + 4) = 4x - 4

-4*x + 4 = 4x - 4

-4x - 4x = -4 - 4

-8*x = -8

x = -8/-8 = 1.

To find the value of y, we can input this value of x in one of the equations:

y = 4 x1 - 4 = 0.

Then we have only one solution, (1, 0).

Therefore, the system is consistent and independent.

The inverse of y = √x - 10 + 4 is y = x^2 + 26 + 8x

What in mathematics is inverse?

A function that "undoes" another function is known as an inverse in mathematics. To put it another way, if f(x) produces y, then y will produce x when y is fed into f's inverse function. Invertible refers to a function that has an inverse, which is represented by the symbol f1.

Given that:

J(x) = √x - 10 + 4

y = √x - 10 + 4

now replace x with y

x = √y - 10 + 4

now solve for y , x = √y - 10 + 4

x + 4= √y - 10

Squaring both the side

x^2 + 16 + 8x = y - 10

y = x^2 + 26 + 8x

Hence the inverse of y = √x - 10 + 4 is y = x^2 + 26 + 8x

The complex number (25 + 22i)² in simplest form a + ib is 141 + 1100i

A complex number is a number in the form z = x + iy where

To find the complex number (25 + 22i)² in the form a + ib, we proceed as follws.

(25 + 22i)² = (25 + 22i)((25 + 22i)

Expanding the brackets, we have that

(25 + 22i)² = (25 + 22i)((25 + 22i)

(25 + 22i)² = [25 × 25 + 25 × 22i + 25 × 21 + (22i)²]

(25 + 22i)² = [625 + 550i + 550i + 484i²]

(25 + 22i)² = [625 + 550i + 550i + 484 × (-1)] Since i² = -1

(25 + 22i)² = [625 + 550i + 550i - 484]

Collecting like terms, we have that

(25 + 22i)² = [625 - 484 + 550i + 550i]

(25 + 22i)² = 141 + 1100i

So, (25 + 22i)² = 141 + 1100i

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

Let (x, y) be the locus point. Then the equation is given as,

(x - 3)² + (y - 9)² = (y - 5)²

Simplify the equation, then we have

(x - 3)² + (y - 9)² = (y - 5)²

Answer: 8 and 4

Step-by-step explanation:

Total ways of required selection is 686, obtained from the sum of the cases of 3, 4 and 5 women in the committee.

Combinations are mathematical operations that count the variety of configurations that can be made from a set of objects, where the order of the selection is irrelevant. You can choose any combination of the things in combinations.

Given that 5 persons are to be selected with a condition of minimum 3 women. Therefore the different possibilities are:

1) 3 women and 2 men

2) 4 women and 1 man

3) 5 women

Final answer will be the sum of the above results.

Total ways to select 3 women from 6 women and 2 men from 8 men,

Total ways =  ⁶C₃ * ⁸C₂

Similarly total ways for 4 women and 1 man =  ⁶C₄ * ⁸C₁

Total ways for 5 women = ⁶C₅ * ⁸C₀

Add the three results to get the final answer,

Total number of ways = (⁶C₃ * ⁸C₂) + (⁶C₄ * ⁸C₁ ) + (⁶C₅ * ⁸C₀)

Total number of ways = 560 + 120 + 6 = 686

Answer:

Length = 50 ft

Width = 15 ft

Area = 750 ft²

Step-by-step explanation:

Define the variables:

Create two equations with the given information.

Given:

⇒ 3L = 10W

Given:

⇒ 2W + 2L = 130

Rearrange the second equation to make W the subject:

⇒ 2(W + L) = 130

⇒ W + L = 65

⇒ W = 65 - L

Substitute this into the first equation and solve for L:

⇒ 3L = 10(65 - L)

⇒ 3L = 650 - 10L

⇒ 13L = 650

⇒ L = 50

Substitute the found value of L into the second equation and solve for W:

⇒ 2W + 2(50) = 130

⇒ 2W + 100 = 130

⇒ 2W = 30

⇒ W = 15

Therefore:

Substitute the found values of W and L into the formula for area of a rectangle to find the area of the pool:

⇒ Area = W × L

⇒ Area = 15 × 50

⇒ Area = 750 ft²
