Point b has the points (5 -2) is rotated 180 about the origin, its image has coordinates

Mrac [35]

When rotating a point 180 degrees about the origin, you are simply inverting the points.

(5, -2) rotated 180 degrees results in (-5, 2).

What is the slope line that passes through the points (10, 8) and (-15, 18)? Write your answer in simplest form

klasskru [66]

Answer: $y=-\frac{2}{5}x+12$

y = mx + b

m = slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{18-8}{-15-10}=\frac{10}{-25}=\frac{2(5)}{-5(5)}=-\frac{2}{5}$

The y-intercept(b) can be found by substituting a point into the function.

$y = -\frac{2}{5}x + b \\\\8=-\frac{2}{5}(10) + b\\\\8=-4+b\\\\b=8+4=12$

Therefore, the function is:

$y=-\frac{2}{5}x+12$

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of

Alexxx [7]

Answer:

The slope is 0.55

Step-by-step explanation:

Right Triangles

The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.

The image below shows the geometric construction. We are required to find the slope the string forms with the ground.

It can be found by using the tangent ratio:

$\displaystyle \tan\theta=\frac{y}{x}$

Substituting y=30 and x=55

$\displaystyle \tan\theta=\frac{30}{55}$

$\displaystyle \tan\theta=0.55$

The slope is 0.55
