What is the slope of the line that passes through the pair of points (-5/3, -1) and (-2, 9/2)?

vovangra [49]

Slope = (9/2 + 1) / (-2 + 5/3)

11/2
= ----------
-1/3
= 11/2 (-3/1)
= -33/2
or
= -16.5

I need some help with this. If you could help me, that would be great.

Vesnalui [34]

Answer:

.31 g / mL

Step-by-step explanation:

Density = mass / volume

Sample 3

mass = 7 1/4 = 7.25

Volume 23.1

Density = 7.25/ 23.1 = .313852814

To the nearest hundredth

.31 g / mL

Can anybody help me please

Question 7: Option 1: x = 33.5°

Question 8: Option 3: x = 14.0°

Step-by-step explanation:

<u>Question 7:</u>

In the given figure, the value of perpendicular and hypotenuse is given, so we have to use any trigonometric ratio to find the value of angle as the given triangle is a right-angled triangle

So,

Perpendicular = P = 32

Hypotenuse = H = 58

So,

$sin\ x = \frac{P}{H}\\sin\ x = \frac{32}{58}\\sin\ x = 0.5517\\x = sin^{-1} ( 0.5517)\\x =33.48$

Rounding off to nearest tenth

x = 33.5°

<u>Question 8:</u>

In the given figure, the value of Base and Perpendicular is given, we will use tangent trigonometric ratio to find the value of x

So,

Perpendicular = P = 5

Base = B = 20

So,

$tan\ x = \frac{P}{B}\\tan\ x = \frac{5}{20}\\tan\ x = 0.25\\x = tan^{-1} (0.25)\\x = 14.036$

Rounding off to nearest tenth

x = 14.0°

in a xy-coordinate system line 1 has a slope of -3. If the points (2,16 and (5,t) are on line 1, what is the value of t?

Dimas [21]

We can use the formula y2-y1/x2-x1 to find our answer. So, we have : t-16/5-2 = -3. We simplify that to t-16/3 = -3. We can then multiply both sides by 3 to get t-16 = -9. Then we can add 16 to both sides to get t = 7.
