Answer:
for the seventh term:
Step-by-step explanation:
First, we need to observe the sequence, it is crescent, every term is bigger than the one before it. Now, if we put our numbers in a graph (added as an image) we'll notice we obtain an exponential function, this is another detail we'll consider to find our equation, from here it's trial an error.
Our formula is:
where n is the number of term:
- it works!
I hope you find this information useful! Good luck!
Answer:
∠A=26º
∠B=137º
∠C=17º
Step-by-step explanation:
We can use the Law of Cosines because we have all 3 side lengths.
cosA =
cosA=28^2+12^2-18^2 / 2(28)(12)
cosA=604/672
cos-1(604/672
angle A ≈ 26º
cosB =
cosB=-316/432
cos-1(-316/432
angle B ≈ 137º
26+137=163
180-163=17
angle C ≈ 17º
Answer:
12 hr. mowing lawns
28 hr. working at Mc Donalds
Step-by-step explanation:
Let t = time mowing lawns
then 40 - t = time working at McDonalds
7,5(40 - t) + 6t = 282
300 - 7.5t + 6t = 282
-1.5t = -18
t = 12 hr. mowing lawns
40 - t = 40 - 12 = 28 hr. working at Mc Donalds
Answer:
x = -3/2
x = -1/2
Step-by-step explanation:
4x^2 + 8x + 3
4x^2 + 2x + 6x + 3
2x(2x+1) + 3(2x+1)
(2x + 3) (2x + 1)
x = -3/2
x = -1/2
Your answer would be choice 3, because when all points of a line lie in a plane, the plain contains the line so the line can contain all of the points. Hope this helped. ;)
