Answer:
45000000000
Step-by-step explanation:
when multiplying exponents, you multiply base numbers with no exponent (9 and five in this case) and numbers with exponents (10 in this case). 9 X 5 is 45 and 10 to the power of 7 times 10 to the power of 2 is 10 to the power of 9 or 1000000000. 45 X 1000000000 is 45000000000.
Answer:
Recall from Logarithm law Log a - Log b = Log (a/b)
so, Log 2 - Log 4 = Log ( 2/4)
= Log ( 1/2).
Also from the law
Log (a/b) = Log a - Log b
i.e Log (1/2) = Log 1 - Log 2
Recall: Log 1 = 0
which implies : Log 1 - Log 2 = 0 - Log 2
= - Log 2
Step-by-step explanation:
Assuming - m = price of each magazine:
Answer: 12/m (b)
It states that Deshawn bout SOME magazines not only one for $12.
If each magazine costs the same amount then we must divide to find how many magazines he bought for $12.
Answer:
A.) 10
Step-by-step explanation:
So draw the points on a graph is the best way to solve the problem, but if you can't then you have to mentally imagine it.
on the X axis B is 5 and C is 11 so the distance or length of the line between the points is 11-5=6
on the Y axis B is 2 and C is -6 so the distance or length of the line between the points is 2-(-6)=8
now you have two lines that can make a right triangle and use the Pythagorean theorem to solve for the long line connecting directly from point B to point C
