Answer:

Step-by-step explanation:

The differences of coordinates are ...

  E-D = (-2, 0) -(-4, -2) = (-2+4, 0+2) = (2, 2)

The slope is the ratio of the y-difference to the x-difference:

  slope of DE = ∆y/∆x = 2/2 = 1

The length is the root of the sum of the squares of those differences:

  length of DE = √(2² +2²) = √8 = 2√2

__

Similarly, the slope of CB is found from ...

  B -C = (1, -2) -(-3, -6) = (1+3, -2+6) = (4, 4)

  slope = 4/4 = 1

And the length is ...

  length of CB = √(4² +4²) = 4√2

__

Because the slopes of DE and CB are both 1, DE ║ CB.

DE = 2√2 and CB = 4√2.

Because 2√2 = (1/2)·4√2, DE = 1/2·CB.

Answer:

64

Step-by-step explanation:

Each side length is being multiplied by 8

Rectangle

3 * 8 = 24

Triangle

4 * 3 = 12

12 / 2 = 6

Now add those two areas together, and you get 30

Answer:

Vennetta

Step-by-step explanation:

Length of Venetta's paper clip chain = 3 feets 5 inches

Length of Bill's paper clip chain = 39 inches

Converting both Venetta's paper clip chain length to inches only :

1 foot = 12 inches

3 feets = (12 * 3) = 36 inches

Hence,

Length of Venetta's paper clip chain in inches :

(36 + 5) inches = 41 inches

41 inches > 39 inches .

Hence, Venetta has the long clip chain.

Answer:

28.284...

Step-by-step explanation:

Use the method TOA, CAH, SOH.

For this question, you have the adjacent and the angle. To find the answer, you need to get the hypotenuse. Therefore, CAH is the method you have to use.

If you have no idea how to use these methods, search for Trigonometry SOH CAH TOA in Yutube.

Answer:

(3,2)

Step-by-step explanation: Because -3 and -2 are negative so when you reflect them the opposite of a negative is positive. So the answer is (3,2) HOPE THAT HELPS.

Answer:

Table 1 is not a function because there are two y-values with the same x-values. Remember... y values can repeat but x values cannot repeat when their corresponding y values are different.

Table 2 is a function.

You would need to omit either (3,7) or (3,-2).

Step-by-step explanation:

Answer:

f(x) = 2x³ - 10x² - 34x + 42

Step-by-step explanation:

The standard form of a cubic equation is f(x) = ax³ + bx² + cx + d

Given conditions are:

First: Zeros of the cubic function are - 3, 1, and 7

Second: f(- 2) = 54

a(-3)³ + b(-3)² + c(-3) + d = 0 ⇔ - 27a + 9b - 3c + d = 0 ...... (1)

a + b + c + d = 0 ......... (2)

a(7)³ + b(7)² + c(7) + d = 0 ⇔ 343a + 49b + 7c + d = 0 ....... (3)

a(-2)³ + b(-2)² + c(-2) + d = 54 ⇔ - 8a + 4b - 2c + d = 54 ...... (4)

We have 4 equations with 4 unknown variables.

Use Cramer's rule to solve the system

A = [tex]\left[\begin{array}{cccc}-27&9&-3&1\\1&1&1&1\\343&49&7&1\\-8&2&-2&1\end{array}\right][/tex] = 6,480

[tex]A_{a}[/tex] = [tex]\left[\begin{array}{cccc}0&9&-3&1\\0&1&1&1\\0&49&7&1\\54&2&-2&1\end{array}\right][/tex] = 12,960

[tex]A_{b}[/tex] = [tex]\left[\begin{array}{cccc}-27&0&-3&1\\1&0&1&1\\343&0&7&1\\-8&54&-2&1\end{array}\right][/tex] = - 64,800

[tex]A_{c}[/tex] = [tex]\left[\begin{array}{cccc}-27&9&0&1\\1&1&0&1\\343&49&0&1\\-8&2&54&1\end{array}\right][/tex] = - 220,320

[tex]A_{d}[/tex] = [tex]\left[\begin{array}{cccc}-27&9&-3&0\\1&1&1&0\\343&49&7&0\\-8&2&-2&54\end{array}\right][/tex] = 272,160

a = [tex]\frac{A_{a} }{A}[/tex] = 2

b = [tex]\frac{A_{b} }{A}[/tex] = - 10

c = [tex]\frac{A_{c} }{A}[/tex] = - 34

d = [tex]\frac{A_{d} }{A}[/tex] = 42  

f(x) = 2x³ - 10x² - 34x + 42

Answer:

10 feet

Step-by-step explanation:

Given

Dimension = 2 feet by 3 feet

Required

Determine the length of the short side if the longer side is scaled to 15 feet

Represent the before and after enlargement as a ratio:

Before Enlargement

Ratio = 2 ft : 3ft

After Enlargement

Ratio = x : 15 ft

Where x represents the length of the shorter side

Since they're both proportional, their ratio must be equal.

So, we have:

2 : 3 = x : 15

Convert ratio to fraction

⅔ = x/15

Multiply both sides by 15

15 * ⅔ = 15 * x/15

15 * ⅔ = x

30/3 = x

10 = x

x = 10

Hence, the length of the shorter side must be 10 feet

19.0476% increase

Step-by-step explanation:

[tex]\frac{x_{2}-x_{1} }{x_{1} } *100[/tex]

(150-126)/126 = 0.190476

0.190476*100 = 19.0476%

Answer:

g = 9. I hope that I help my buddy out :)

Answer:

g=9

Step-by-step explanation:

Step 1: Subtract 5 from both sides.

-1/3g=5-5=2-5

-1/3g=-3

Step 2: Multiply both sides by 3/(-1).

(3/-1) x (-1/3g)=(3/-1) x (-3)
