Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 6) and (x₂, y₂ ) = (8, 4)

m = \frac{4-6}{8-3} = - \frac{2}{5}, hence

y = - \frac{2}{5} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (8, 4), then

4 = - \frac{16}{5} + c ⇒ c = 4 + \frac{16}{5} = \frac{36}{5}

y = - \frac{2}{5} x + \frac{36}{5} ← equation of line

4 2/3 ÷ 7 to the lowest terms ​
exis [7]

Answer:

4 2/3 divided by 7. You can do 14/3 by making it an improper fraction. Then you can do 14/3 divided by 7/1.

(LCR) 14/3 * 1/7 = 14/21.

Simplify by 7.

14 divided by 7 is 2.

21 divided by 7 is 3.

The answer is 2/3!

Find the value of cos θ if the angle θ is in the third quadrant and sinθ= -0.8
Rudiy27

Correct option is D) -0.6.

<u>Step-by-step explanation:</u>

We have sin\alpha  = -0.8 . Also, we know that cos\alpha  = \sqrt{1- (sin\alpha } )^{2} . Let's find out value of cos\alpha  using above formula:

cos\alpha  = \sqrt{1- (sin\alpha } )^{2}

⇒ cos\alpha  = \sqrt{1- (sin\alpha } )^{2}

⇒ cos\alpha  = \sqrt{1- (-0.8 } )^{2}

⇒ cos\alpha  = \sqrt{1- (0.64 } )^{}

⇒ cos\alpha  = \sqrt{0.36}

⇒ cos\alpha  = 0.6

But we know that cos\alpha is negative in third quadrant , Therefore cos\alpha  = -0.6.

Hence, correct option is D) -0.6.
