Find the slope of (0,1) (3,10) (6,19) (9,28) (12,37)

stira [4]

9/3 or 3
slope is rise over run. or x over y.
look at your Y points... 1, 10, 19, 28, 37. They go up 9 each time, right? 1 + 9 = 10 + 9 = 19...etc.

Now, look at your X points... 0, 3, 6, 9, 12. They go up 3 each time, right? 0 + 3 = 3 + 3 = 6...etc.

Since you go up 9 for the y axis and 3 for the x axis...

The sum of two consecutive odd integers is 128. find the two integers.

Basile [38]

<span>Call the first odd number x.
That means the next odd number would be x+2.
For example, if the first odd number is 9 then the next one would be 11, which is why it is plus 2. Okay?

So then, x+x+2=128
2x+2=128
2x=126
x=63
x+2=65
Thus, the two consecutive odd numbers are 63 and 65.

Hope I helped :)</span>

12. The geographic grid apportions the globe into hemispheres of 180 lines of longitude. Based on your knowledge of basic geomet

ANEK [815]

Answer:

For the first question, 180 degrees equals to a half of the sphere. For the second question, you need 24 central meridians for a complete sphere, which are exactly the hours in a day.

Step-by-step explanation:

A sphere is basically a 3D circle. As a circle has 360 degrees, 180 degrees would be half of a circle. Imagine you are on a satellite over the north pole or the south pole and you have a way to cut the earth by the middle. You will get two halves of sphere.

About the second question, you may need to have in mind that a day is the time spent for the earth to rotate all 360 degrees over its own axis. British fellow, on XIX century, decided they were the center of the world. As previously, back in the days, some other people decided a day had 24 hours, they decided to draw this lines and divide the earth in 24 pieces, so they could knew which time was on every point their extense kingdom had. As I said, a circle has 360 degrees, (360 degrees)/(24 hours) equals to 15 degrees.

Without drawing the graph of the equation, determine how many points the given equation have in common with the x-axis and where

Gala2k [10]

Remark
It's asking you to complete the square to find the vertex.

Solve
y = -2x^2 + x + 3 Put brackets around the first 2 terms.
y = (-2x^2 + x) + 3 Pull out the 2.
y = -2(x^2 - 1/2 x) + 3 Be especially observant of the sign on 1/2x Divide the middle term's number by 2 and square it.
y = -2(x^2 - 1/2 x + [(1/2) / 2]^2 ) + 3 [1/2 divided by 2 is 1/4. (1/4)^2 = 1/16; 2*(1/16) = 1/8
y = - 2(x^2 - 1/2 x + (1/4)^2 ) + 3 + 1/8
y = -2(x - 1/4)^2 + 3 1/8

Comment
Answer to your question. The maximum value (3 1/8) is above the y axis. That means the graph of the equation crosses the x axis twice. I'm going to include the graph because in answering the question, there is no harm in seeing the graph.
