The Pythagorean theorem was put forward by the Greek mathematician and philosopher named Pythagoras.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other sides.

Step by step explanation :Side BC:

BC² = DC² + DB²

BC² = 3m² + 4 m²

BC² = 9m + 16m

BC² = √25 m

BC² = 5 m

Side DC:

DC² = BC² - DB²

DC² = 5m² - 4 m²

DC² = 25 m - 16m

DC² = √9 m

DC² = 3 m

Consider the expression 8-6x+x^2, Is the expression equivalent to (x-4)(x-2)?​

Answers

Answer:

Yes

Step-by-step explanation:

Factoring is the process of breaking a polynomial into its factors.

Standard Form

It is easiest to factor when in standard form. Standard form is when the terms are listed from highest power to lowest.

Standard form is [tex]x^2-6x+8[/tex]

Factoring

To find if two expressions are equal we can either factor the quadratic or multiply out the binomials. I find factoring to be faster and easier, so I will show that.

There are multiple techniques to factor; I will be explaining one of them. One way to factor quadratics is to find 2 numbers that multiply to c (the constant) and sum to b (the second term). In this case, the numbers -4 and -2 fit these requirements.

-4 * -2 = 8-4 + -2 = -6

This means that [tex]x^2-6x+8[/tex] factored is [tex](x-4)(x-2)[/tex]. Thus, they are equivalent.

Find the midpoint of the segment with the following endpoints.

Answers

Answer: The midpoint is (5,5.5)

Step-by-step explanation:

Adding X1 And X2 equals 10. Then the x variables have to be divided which is 10 divided 2 equals 5, the 5 represents the x value of the x part of midpoint. (5,?)

Adding Y1 and Y2 equals 11. Then the y variables have to be divided by 2 which is 11 divided by 2 equals 5.5, the 5.5 represents the y value of the midpoint. (?,5.5)

The final answer is Midpoint = (5,5.5)

Given f (x) = 2x + 3 and g(x) = x2 – 5x + 6, compute (fog)(x) =

Answers

Answer:

(fog)(x) = 2x² - 10x + 15

Step-by-step explanation:

(fog)(x) is called a composite function, where x in f(x) substituted by g(x).The range of g(x) is the domain of f(x)

Let us solve our question

∵ f(x) = 2x + 3

∵ g(x) = x² - 5x + 6

→ We need to compute (fog)(x)

∴ Substitute x in f(x) by g(x)

∵ (fog)(x) = 2(x² - 5x + 6) + 3

→ Multiply the bracket by 2

∵ 2(x² - 5x + 6) = 2(x²) - 2(5x) + 2(6)

∴ 2(x² - 5x + 6) = 2x² - 10x + 12

→ Substitute it in the composite function above

∴ (fog)(x) = 2x² - 10x + 12 + 3

→ Add the like terms 12 and 3

∴  (fog)(x) = 2x² - 10x + 15

Last year you could get a hamburger, fries, and a cola at Francisco's Drive-In for $2.00. Since the price of a hamburger has increased 10%, the price of fries has increased 30%, and the price of a cola has increased 50%, the same meal now costs $2.58. If the price of a cola is now 9 cents more than that of a hamburger, what was the price of each item last year?

Answers

Answer:

hamburger = h = $0.22

Fries = f = $0.96

Cola = c = $0.82

Step-by-step explanation:

Let

last year's price for each item be hamburger = h

Fries = f

Cola = c

h + f + c = 2.00 (1)

The price of a hamburger has increased by 10%

New price of hamburger = 1.10h

The price of fries has increased by 30%

New price of fries = 1.30f

The price of cola has increased by 40%

New price of cola = 1.40c

The same meal now costs $2.58.

1.1h + 1.3f + 1.4c = 2.58 (2)

If the price of a cola is now 9 cents more than that of a hamburger

1.4c = 1.1h + .09

1.4c - 1.1h = .09

Multiply (1) by 1.4

h + f + c = 2.00 × 1.4

1.4h + 1.4f + 1.4c = 2.8 (3)

1.1h + 1.3f + 1.4c = 2.58 (2)

subtract the new equation:

0.3h + 0.1f = 0.22

Multiply by 10

3h + f = 2.2

Recall,

1.4c - 1.1h = .09

1.4h + 1.4f + 1.4c = 2.8 (3)

- 1.1h + 0.0f + 1.4c = .09

Subtract

2.5h + 1.4f = 2.71

multiply by 10

25h + 14f = 27.1

Recall

3h + f = 2.2

Multiply by 14

42h + 14f = 30.8

25h + 14f = 27.1

Subtract to eliminate f

17h = 3.7

Divide both sides by 17

h = 3.7 / 17

= 0.22

h = 0.22

Substitute h into

1.4c - 1.1h = .09

1.4c - 1.1(0.22) = .09

1.4c - 0.242 = .09

1.4c = .09 + 0.242

1.4c = 1.142

Divide both sides by 1.4

c = 1.142 / 1.4

= 0.82

c = 0.82

Substitute values of c and h into

h + f + c = 2.00

0.22 + f + 0.82 = 2.00

1.04 + f = 2.00

f = 2.00 - 1.04

f = 0.96

Therefore, the price of each item last year was

hamburger = h = $0.22

Fries = f = $0.96

Cola = c = $0.82

You recently borrowed $500 from a friend. You signed a contract that requires you to pay back one third of the loan every month for three months. How much will you have to pay back each of the first two months? How much will you have to pay back the third month?

Answers

The amount of money I would repay in the first month is $166.67.

The amount of money I would repay in the second month is $166.67.

The amount of money I would repay in the third month is $166.66.

How much would I repay each month?

In order to determine the money that would be repaid each of the first two months, multiply 1/3 by the amount of the loan.

1/3 x $500 = $166.67

Amount to be repaid in the third month = $500 - (166.67 x 2) = $166.66

1. How do you define quadratic equations?​

Answers

Answer:

[tex]ax^{2} +bx+c^{2}=0[/tex]

Step-by-step explanation:

A quadratic equation is a equation that takes the form: [tex]ax^{2} +bx+c^{2} = 0[/tex]

   Ex. Using our definition of quadratic equations, [tex]ax^{2} +bx+c^{2}=0[/tex],

What is the direction of W? PLEASE HELP ASAP

Answers

Answer:

  -161.57°, or 198.43°

Step-by-step explanation:

The third-quadrant angle can be found using the usual rectangular-to-polar conversion. The angle is given by ...

  θ = ATAN2(x, y) = ATAN2(-12, -4) ≈ -161.57°

__

More conventionally, the reference angle is ...

  tan(θ) = y/x = -4/-12 = 1/3

  θ = arctan(1/3) ≈ 18.43° . . . . angle from -x axis (CCW)

Since this is a 3rd-quadrant angle, the positive angle value will be 180° plus the reference angle:

  180° +18.43° = 198.43°

The angle most directly measured from the +x axis is ...

  360° -198.43° = -161.57°
