(f+g)(x)=f(x)+g(x)=(2x-6)+(4x+7)=6x+1

(f-g)(x)=f(x)-g(x)=(2x-6)-(4x+7)=-2x-13

(fg)(x)=f(x)×g(x)=(2x-6)(4x+7)=8x^2-10x-42

(f+g)(-2)=f(-2)+g(-2)=(2(-2)-6)+(4(-2)+7)=-11

Evaluate each expression for g = -7 and h = 3 and match it to its value.

Arturiano [62]

Answer:

The values of given expressions are:

1. gh = -21

2. g^2 - h = 46

3. g + h^2 = 2

4. g + h = -4

5. h - g = 10

6. g - h = -10

Step-by-step explanation:

Given values of g and h are:

g = -7

h = 3

1. gh

The two numbers are being multiplied

Putting the values

$gh = (-7)(3) = -21$

2. g^2-h

Putting the values

$=(-7)^2-3\\=49-3\\=46$

3. g+h^2

Putting the values

$= -7 + (3)^2\\=-7+9\\=2$

4. g+h

Putting the values

$= -7+3\\=-4$

5. h-g

Putting the values

$= 3 - (-7)\\=3+7\\=10$

6. g-h

Putting values

$=-7-3\\=-10$

Hence,

The values of given expressions are:

1. gh = -21

2. g^2 - h = 46

3. g + h^2 = 2

4. g + h = -4

5. h - g = 10

6. g - h = -10

Consider this equation. cos(theta) = (-2√5)/5. If theta is an angle in quadrant II, what is the value of sin(theta)? NO LINKS!!!

vlada-n [284]

In second quadrant sin and cosec are positive

$\\ \tt\hookrightarrow sin^2\theta=1-cos^2\theta$

$\\ \tt\hookrightarrow sin^2\theta=1-(\dfrac{-2\sqrt{5}}{5})^2$

$\\ \tt\hookrightarrow sin^2\theta=1-\dfrac{20}{25}$

$\\ \tt\hookrightarrow sin^2\theta=\dfrac{5}{25}$

$\\ \tt\hookrightarrow sin\theta=\dfrac{\sqrt{5}}{5}$

$\\ \tt\hookrightarrow sin\theta=\dfrac{1}{\sqrt{5}}$

A card is randomly selected from a standard

Anni [7]

Answer:

5.8% or 6%

Step-by-step explanation:

6 face cards in a deck minus the red ones so it would be [6-3=3]

52 cards are in a deck and you have 3 black face card so it would be [3/52=0.0576]

Then to get your percentage it would be [0.0576 x 100=5.76%]

5.76 rounded up is 6%
