Answer:
18) 4 * 10 ^ -10
19) t ^ 9
Step-by-step explanation:
18. When multiplying in scientific notation, just multiply the regular numbers together and add the exponents for the tens.
So it'll be 40 * 10^-11
However, the beginning number should have the decimal right after the 4, not any place after (for example, it's 3.056, not 30.56 or 3056.)
To fix this, move the decimal place forward one space from 40. to 4.0, and add 1 to the -11 power.
So the answer is now 4 * 10^-10
19. When dividing exponents, if the base number is the same, you can divide. (Basically, you can not divide x^2 and y^3 because x and y aren't the same)
Since in this case it's t, you can divide.
Dividing exponents is simple: just subtract them.
14 - 5 = 9
so the answer is t ^ 9
Answer:
Yes.
Step-by-step explanation:
Yes. Because opposite angles are congruent.

Answer:
they will be the same at 11 months
Step-by-step explanation:
the equations for this are
y = 40+55x
and
y = 165+30x
where x is the number of months
if you plug this into your graphic calc you see they are equal at 11 therefore, 11 months
Answer:
K = 
Step-by-step explanation:
P = KTV
Divide both sides by TV
(P/TV) = K
