Answer:
36
2 x 18
2 x 2 x 9
2 x 2 x 2 x 3
Step-by-step explanation:
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Let x represent the smaller angle:
x + (x + 81.2) = 180
2x + 81.2 = 180
2x = 98.8
x = 49.4 degrees
therefore:
smaller angle = 49.4 degrees
larger angle = 49.4 + 81.2
= 130.86 degrees
Answer:
f(2)=0
f(-4)=24
Step-by-step explanation:
We are given
f(n)=n^2-2n
We are asked which of the following are true?
f(2)=0
f(1)=3
f(-4)=24
f(5)=35
f(-2)=0
Let's start with f(2)=0.
f(2)=2^2-2(2)
f(2)=4-4
f(2)=0
So f(2)=0 is true.
Moving on to f(1)=3.
f(1)=1^2-2(1)
f(1)=1-2
f(1)=-1
So f(1)=3 is false.
Now for f(-4)=24.
f(-4)=(-4)^2-2(-4)
f(-4)=16+8
f(-4)=24
So f(-4)=24 is true.
f(5)=35?
f(5)=5^2-2(5)
f(5)=25-10
f(5)=15
So f(5)=35 is false.
Finally f(-2)=0.
f(-2)=(-2)^2-2(-2)
f(-2)=4+4
f(-2)=8
So f(-2)=0 is false.
Let b for the number of bicycles, and t for the number of tricycles.
2b+3t=39 ( a bicycle has 2 wheels and a tricycle has 3 wheels)
b=t+2 =>t=b-2
substitute b for t: 2b+3(b-2)=39
2b+3b-6=39
5b=45
b=9
the club buys 9 bicycles and 7 tricycles.
Answer:
We have 8 / (-4) = - 2; - 16 / 8 = - 2; 32 / -16 = - 2;
The common ratio of the sequence is - 2.
