2.34 im pretty sure. Hope it helps!
32^2 +24^2 = 1600
Square root of 1600 = 40
b = 40.
More info needed for a and c.
Answer: simplest reason is that Infinity is not a number, it is an idea.
So 1∞ is a bit like saying 1beauty or 1tall.
Maybe we could say that 1∞= 0, ... but that is a problem too, because if we divide 1 into infinite pieces and they end up 0 each, what happened to the 1?
In fact 1∞ is known to be undefined.
But We Can Approach It!
So instead of trying to work it out for infinity (because we can't get a sensible answer), let's try larger and larger values of x:
graph 1/x
x 1x
1 1.00000
2 0.50000
4 0.25000
10 0.10000
100 0.01000
1,000 0.00100
10,000 0.00010
Now we can see that as x gets larger, 1x tends towards 0
We are now faced with an interesting situation:
Step-by-step explanation:
Well I don't know !
Let's check out the choices:
A). 3a - 4b = 21, a=0, b=7
3(0) - 4(7) = 21
0 - 28 = 21 Nope. That's not true.
B). 3a - 4b = 21, a=-3, b=2
3(-3) - 4(-2) = 21
-9 + 8 = 21
-1 = 21 Nope. That's not right.
C). 3a - 4b = 21, a=-2, b=-3
3(-2) - 4(-3) = 21
-6 + 12 = 21
6 = 21 Nope. That's not it.
Only one choice left.
This one had better be it:
D). 3a - 4b = 21, a=7, b=0
3(7) - 4(0) = 21
21 - 0 = 21
21 = 21 Yay ! That's it !
The correct answer would be 28,053
