Answers

Answer:

y=-2/5x +8

Step-by-step explanation:

use y=mx+b      look at where the line intercepts with the y-axis and that is at 8 so that is your b. Then find two points and count how many down or up it is to get from the higher up point (i usually use the one that intercepts at the y-axis) to same line as the other point, in this case thats down two. Then count how many to the right it is and in this case it is 5. so since it went down thats -2 over 5 so then you just fill that into the y=mx+b   and you should get   y=-2/5x+8

Hope this helped!

Step-by-step explanation:

Using the cofunction identity

sec(90 - x)° = cscx° , then

7A = 90 - 5A ( add 5A to both sides )

12A = 90° ( divide both sides by 12 )

A = 7.5°

if the velocity is big, must there be forces on it?

Answers

Answer:

Acceleration and velocity

Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

How do I draw and determine the equation of a trend line on a scatterplot

Answers

Step-by-step explanation:

Step 1: Draw your trend line.

You begin by drawing your trend line. You want your trend line to follow your data. You want to have roughly half your data above the line and the other half below the line, like this:

trend line equation

Step 2: Locate two points on the line.

Your next step is to locate two points on the trend line. Look carefully at your trend line and look for two easy to figure out points on the line. Ideally, these are points where the trend line crosses a clearly identifiable location.

For the trend line that we just drew, we can see these two easily identifiable points.

trend line equation

We can easily identify these two points as (3, 3) and (12, 6).

Step 3: Plug these two points into the formula for slope.

The formula for slope is this one:

trend line equation

We can label our first point as (x1,y1), and our second point as (x2,y2). So our x1 is 3, our y1 is 3, our x2 is 12, and our y2 is 6. Plugging these values into the equation for slope and evaluating, we get this:

trend line equation

So our slope is 1/3.

Consider the following formula y−p/2=e. Rearrange the formula to solve for "p":

Answers

Answer:

p = 2y - 2e

Step-by-step explanation:

Eliminate the fraction by multiplying all terms by 2:

2( y−p/2=e) = 2y - p = 2e

Now subtract 2e from both sides, obtaining:  2y - 2e = 0.

Finally, add p to both sides:  p = 2y - 2e

Answer: Its C

Step-by-step explanation:

24   +   25   +   26   +   27   +   28   +   29   +   30   +   31   +   32   +   33   +   34   ÷   11 = 29

Answer:

c

Step-by-step explanation:

The mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

Set 1

sum = (2 × 27) + (2 × 28) + (3 × 29) + (2 × 30) + (1 × 33)

       = 54 + 56 + 87 + 60 + 33 = 290

The count is 10 ( number of dots ), then

mean = [tex]\frac{290}{10}[/tex] = 29

Set 2

sum = (4 × 24) + (4 × 25) + (2 × 27)

       = 96 + 100 + 54 = 250

The count is 10 ( number of dots ), then

mean = [tex]\frac{250}{10}[/tex] = 25
