Answer:
21+4=25
Step-by-step explanation:
This likely has a pattern. Lets see if we can find it.
The sum of a triangle is 180
The sum of a 4 sided figure is 360
The sum of a 5 sided figure is 3*180 = 540
The sum of a 6 sided figure is 4*180 = 720
==========================
The pattern looks like it it (( n-2 )*180) for any polygon where n is the number of sides of the polygon.
You can convince yourself (but this is not a formal proof) by starting with a 6 sided figure. Pick one point on the figure where 2 sides meet. Draw diagonals to all the points not connected to the point you've chosen. You should be able to get 4 such diagonals. You have created 4 triangles.
4*180 = 720 just what your estimate said.d
8 sides will give 6*180 = 1080 degrees and if you keep going on the above table you will see 1080 come up for 8. I'd post a diagram but I don't know how to upload it.
This procedure is extremely important. There is a new math around where these kinds of problems are solved by reducing them to much simpler questions, and getting an answer for them. The pattern is what you are looking for.
Now you can do the rest of the questions.
Pentagon: (5 - 2) * 180 =
Octagon: (8 - 2) * 180 =
dodecagon (12 - 2)*180=
40 sides 38*180 =
100 sides 98 * 180 =
9514 1404 393
Answer:
b = -0.0012a +211
208.36 °F at 2200 ft
Step-by-step explanation:
We are given two points:
(a, b) = (8100, 201.28) and (4300, 205.84)
The slope of the desired line can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (205.84 -201.28)/(4300 -8100) = 4.56/-3800 = -0.0012
The "y-intercept" of the function can be found from ...
y-intercept = b -ma
y-intercept = 201.28 -(-0.0012)(8100) = 211.00
So, the function of interest is ...
b = -0.0012a +211
__
At 2200 ft, the boiling point is ...
b = -0.0012×2200 +211 = -2.64 +211 = 208.36
The boiling point of the liquid at 2200 ft is 208.36 °F.
Answer:
Answer should be 5/2 I thinkkkkk
The degree of a polynomial is categorized by its highest power of its leading variable.
<h3>Degree and number of terms of a polynomial</h3>
Given the following polynomial functions, we are to classify them based on their degrees and the number of terms
For the polynomial function 5x^4 - 7x + 9
The degree is 4 being quartic and there are three terms in the expression
For the polynomial 2x3 + 3 < 3, the degree is 3 (cubic) with three terms in the expression.
For a Quintic quadnomial, the degree of the polynomial is 5.
