Answer:
7.5* 10^8
Step-by-step explanation:
(1.5 x 10^5)(5 x 10^3)
Multiply the numbers
1.5*5=7.5
Add the exponents
10 ^(5+3) = 10^8
Put back together
7.5* 10^8
This is in scientific notation
Well if the top thing has nothing to do with it then just count the squares for one of them and then put a decimal point before that number for the decimal and put a percent sign next to it for the percent. Example for 1: there's 43 squares so .43 and 43%
Answer:
f(x)=49
g(x)= -21
Step-by-step explanation:
Let's start with f(-3)
Replace x with -3:
-2(-3)^3-5
Cube -3 (The ^3 is also called cube)
-2(-27) -5
-2 times -27 is 54
54-5 is 49
Now with g(4)
g(4)= -5(4) - 1
-5 times 4 is -20
-20-1 is -21
Hope this helps!
