Answer:
103
Step-by-step explanation:
the line is 180 degree angle also know as a straight angle if you take the 40 and the 33 away from 180 you are left with 103 and that is angle a
The common difference is 6
Step-by-step explanation:
Given sequence is:
7, 13, 19, 25....
The common difference is the difference between consecutive terms of an arithmetic sequence.
Here,
Hence,
The common difference is 6

Find rates of change until you find a constant.
dy/dx=1,2,3,4,5,6
d2y/dx2=1,1,1,1,1
So the acceleration, d2y/d2x, is constant. This means that this is a quadratic sequence of the form a(n)=an^2+bn+c. So we can set up a system of equations to solve for the values of a,b, and c. Using the first three points, (1,1), (2,2), and (3,4) we have:
9a+3b+c=4, 4a+2b+c=2, and a+b+c=1 getting the differences...
5a+b=2 and 3a+b=1 and getting this difference...
2a=1, so a=1/2 making 5a+b=2 become:
2.5+b=2, so b=-1/2, making a+b+c=1 become:
1/2-1/2+c=1, so c=1 so the rule is:
a(n)=0.5x^2-0.5x+1 or if you prefer to not have decimals
a(n)=(x^2-x+2)/2
The length of QP is is 38 because it is congruent to QR
Answer:
Option 1
Step-by-step explanation:
P(glasses' ^ internet) = 3/20 = 0.15
P(glassses') = 8/20 = 0.40
P(internet) = 7/20 = 0.35
(0.40×0.35) = 0.14
