What is the slope of the line that passes through the points (2, 8) and (6, 12)?

2 answers:

6 0

Slope = (y2 - y1) / (x2 - x1)
set 1 : (2,8)....x1 = 2 and y1 = 8
set 2 : (6,12)...x2 = 6 and y2 = 12
now we sub
slope = (12 - 8) / (6 - 2) = 4/4 = 1 <===

Divide $150 into the ratio 2:5:3

pentagon [3]

Answer:

$30, $75, $45

Step-by-step explanation:

We can set up an equation, where x is an unknown value:

2x+5x+3x=150

10x = 150

x=15

Now that we know what x is, we can plug x in to solve for 2x, 5x, and 3x:

2x=2*15=30

5x=5*15=75

3x=3*15=45

Therefore, the answer is $30, $75, $45

Evaluate sec960°. 1. -2 2. - 2 sqrt3/3 3. 2sqrt 3/3 4. 2

Eduardwww [97]

Answer:

-2

Step-by-step explanation:

We want to evaluate;

$\sec960\degree$

We use the reciprocals of trigonometric ratios to obtain;

$\sec960\degree=\frac{1}{\cos960\degree}$

The 960 degree angle makes an angle of 60 degree with the positive direction of the x-axis and it is in the 3rd quadrant.

This implies that;

$\sec960\degree=\frac{1}{-\cos60\degree}$

We use special trigonometric ratios to obtain;

$\sec960\degree=\frac{1}{-\frac{1}{2}}$

$\sec960\degree=-2$
