Answer:
Step-by-step explanation:
So we have the formula:
And we want to make r the subject of the formula.
So, first, let's multiply both sides by (r-3). The right will cancel. So:
Distribute the t:
Subtract rt from both sides. The left cancels:
Factor out an r from the right:
Divide both sides by (1-t). The right cancels:
Simplify the negatives:
Flip:
And we're done!
Answer:
Step-by-step explanation:
let 2x be the length of chord tangent to first circle.
so x=√(14²-6²)=√(14+6)(14-6)=√(20×8)=√160=4√10
length of chord=2x=2×4√10=8√10
Well, you would have to multiply 8 by whatever factorial of 3, in this case 4 for the number of weeks
The equation is 8 x 3^4 which equals 648
My only thing is that they only triple in SIZE, and not multiply (as in make more of themselves) so technically speaking, there would still be 8 bacteria, just much bigger
Answer:
Step-by-step explanation:
Multiplying 5 by itself is the same thing as raising it to the second power:
We multiply 2 by itself two seperate times. That's the same thing as raising 2 to the second power to the second power or in simpler terms raising two to the fourth power:
Since only multiplication is present, we can combine the two terms to get:
11 x < - 66
x < - 66 / 11
x < - 6
hope this helps!
