Since you know that interior angles of one transversal add up to 180, we can subtract 72 from 180 to solve for angle DAB. 180-72=108. Our answer is angle DAB=108°
Answer:
Hey there!
We have an=a1(r^n-1), which is the formula for a geometric sequence.
The common ratio is 3, and 2 is the 1st term.
Thus, we have a1=2(3)^(n-1)
Hope this helps :)
Analyze perfect cubes:
1^3 = 1
2^3 = 8
3^3 = 27
Since 12 is between 8 and 27, cube root of 12 is between 2 and 3.
You also know it is much closer to 2, since 12 is much closer to 8.
A good guess would be 2.25
(2.25)^3 = 11.39
This is close but slightly less than 12.
When you use your calculator you should get 2.2894.
Answer:
f(x)=6x-5
Step-by-step explanation:
The common difference is 6 because of the following:
7-1=6
13-7=6
19-13=6
25-19=6
31-25=6
The common difference is the slope of the linear equation.
Slope-intercept form for a function is f(x)=mx+b where m is the slope and b is the y-intercept.
We just found m=6.
f(x)=6x+b
The y-intercept happens at x=0.
I'm referring to looking at the data as:
x | y
1 | 1
2| 7
3| 13
4| 19
5| 25
6| 31
We can use the pattern that y goes up by 6 as x goes up by 1 to find what happens at x=0.
x| y
0 1-6=-5
So b=-5.
So the function that we are looking for is f(x)=6x-5.
B: because she gained and didn’t decrease
Explanation:
A: 30
B:36
C:11
D: -5
So b is correct because it’s Greater
