By using Pythagoreans Theorem: a^2 + b^2 = c^2

Several ways like somebody said below you can use use pythag assuming u know the other 2 side lengths w/ a^2+b^2=c^2
however if you do not know the other two side lengths you must use trigonometry and sohcahtoa
sin(angle)= the side length opposite the angle to be referred to as O
divided by the longest side length (hypotenuse)or the angle directly across from the 90 degree angle to be referred to as H
cos(angle) the side length adjacent (next to) the known angle to be referred to as A/H
and finally tan(angle)O/A
if you are still having trouble with this id suggest youtubing "get triggy with it" decent video that explains trig pretty well as well as how to find a missing angle rather than a side length
hope this helps -j

Write a point slope form equation and slope intercept equation. Passes through (-1,-6), slope= -4

zavuch27 [327]

Answer:

The point-slope form would be y + 6 = -4(x + 1) and the slope-intercept form would be y = -4x - 10

Step-by-step explanation:

In order to find the point-slope form, you simply need to put the point and the slope into the base form.

y - y1 = m(x - x1)

y - -6 = -4(x - -1)

y + 6 = -4(x + 1)

Now to find the slope-intercept, simply solve for y.

y + 6 = -4(x + 1)

y + 6 = -4x - 4

y = -4x - 10

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 1 intermediate stop on the way to New Y

Zolol [24]

Answer:

Algebra - Question related to graphs?

A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?

Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times?

Dose that make sense?

1: Yes

Way out.

NY,S1,S2,S3,Ch

Way back

Ch,S4,NY

The Ch is the same therefore total is 7.

a(n)=-6+(n-1)(6)

3: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times.........

4: A plane that carries mail makes a round trip each day from Chicago to New York. It makes 3 intermediate stops on the way to New York and 1 intermediate stop on the way back to Chicago. Suppose you make a graph of the altitude of the plane for one day, with time on the horizontal axis and altitude on the vertical axis. How many times will the graph touch the horizontal axis?

i guess it would be 7 as the answer because: Well, the only time the graph would touch the x-axis (horizontal axis) would be at 0 altitude so, counting the 3 stops on the way to NY then the 1 stop back to Chicago would be four. But if you think about it when the planes are at it's destination it's also at 0 altitude. So you'd add another 3 (Chicago to New York then back to Chicago)...right? Then the graph would touch x-axis approximently 7 times.........

Step-by-step explanation: Different Brainly's

1: Answer: 7

Step-by-step explanation: The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.

So, cumulatively the altitude will touch the horizontal axis seven times.

2: I Don't Know

3: Answer:

5 is the right answer

Step-by-step explanation:

The graph will touch the horizontal x each time the altitude is zero.

Tha happens: 1st in Chicago before taking off, 2nd, in the intermediate place before getting to NY, 3rd in NY, 4th in the intermediate place before getting to Ch, and 5th when arrives to Ch.

4: Answer:

Step-by-step explanation:

The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.

So, cumulatively the altitude will touch the horizontal axis seven times.

Use the given information to write the standard form equation of a circle:

tiny-mole [99]

Answer:

The formula for the equation of a circle is (x – h) 2 + (y – k) 2 = r 2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

Write an equivalence chain with fraction that equals 1/2

alexgriva [62]

Hi.

An example of a fraction equivalence chain is this:

$\frac{1}{2}, \frac{2}{4}, \frac{4}{8}, \frac{8}{16}, \frac{16}{32}$

You can keep multiplying $\frac{1}{2}$ by 2 to get a fraction chain.

Hope this helps!
