Answer: B. C^2 +c+5

Step-by-step explanation:

group them in families

(c^2-6c) +(7c+5)

-6c+7c

C^2 +c +5

*Keep in mind that if 1 is in front of the variable than just put the letter/symbol

Answer:

It is B

Step-by-step explanation:

(c² - 6c) + (7c + 5)

c² is it's own term

-6c + 7c combine to 'c'

5 is it's own term.

So it is c² + c +5

For 0 ≤ θ < 2 π what are the solutions to sin^2(θ) =2sin^2(θ/2)

gregori [183]

Recall the half-angle identity for sine,

sin²(x/2) = (1 - cos(x))/2

Then the given equation is identical to

sin²(θ) = 1 - cos(θ)

Also recall the Pythagorean identity,

sin²(θ) + cos²(θ) = 1

Then we rewrite the equation as

1 - cos²(θ) = 1 - cos(θ)

Factoring the left side, we have

(1 - cos(θ)) (1 + cos(θ)) = 1 - cos(θ)

and so

(1 - cos(θ)) (1 + cos(θ)) - (1 - cos(θ)) = 0

and we factor this further as

(1 - cos(θ)) (1 + cos(θ) - 1) = 0

which gives

cos(θ) (1 - cos(θ)) = 0

Then either

cos(θ) = 0 or 1 - cos(θ) = 0

cos(θ) = 0 or cos(θ) = 1

[θ = arccos(0) + 2nπ or θ = -arccos(0) + 2nπ]

… or [θ = arccos(1) + 2nπ or θ = -arccos(1) + 2nπ]

(where n is any integer)

[θ = π/2 + 2nπ or θ = -π/2 + 2nπ] or [θ = 0 + 2nπ]

In the interval 0 ≤ θ < 2π, we get three solutions:

• first solution set with n = 0 ⇒ θ = π/2

• second solution set with n = 1 ⇒ θ = 3π/2

• third solution set with n = 0 ⇒ θ = 0

So, the first choice is correct.

Which linear function represents the line given by the point-slope equation y – 8 = y minus 8 equals startfraction one-half endf

Marina CMI [18]

The linear function which represents the line given by the point-slope equation is (B) $f(x)=\frac{1}{2} x+6$ .

<h3>What is a linear function?</h3>

The word linear function in mathematics refers to two distinct but related concepts.
A linear function in calculus and related fields is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.

To find the linear function which represents the line given by the point-slope equation:

Given: $y-8=\frac{1}{2} (x-4)$

Distribute the right side:

$y-8=\frac{1}{2} (x)-\frac{1}{2} 4\\y-8=\frac{1}{2} x-2$

Adds 8 on both sides:

$y=\frac{1}{2}x-2+8\\y=\frac{1}{2}x+6$

Convert to function notation:

$f(x)=y\\f(x)=\frac{1}{2} x+6$

Therefore, the linear function which represents the line given by the point-slope equation is (B) $f(x)=\frac{1}{2} x+6$ .

The complete question is given below:

Which linear function represents the line given by the point-slope equation y – 8 = y minus 8 equals start fraction one-half end fraction left-parenthesis x minus 4 right-parenthesis. (x – 4)?

A) F(x) = f(x) equals StartFraction one-half EndFraction x plus 4.X + 4

B) f(x) = f(x) equals StartFraction one-half EndFraction x plus 6.

C) X + 6 f(x) = f(x) equals StartFraction one-half EndFraction x minus 10.X –10

D) f(x) = f(x) equals StartFraction one-half EndFraction x minus 12.X – 12
