Answer:
10^2 = 10 x 10 = 100
3.02 x 100 = 302
10^-2 = 1/(1/10/10) = 1/100 = 0.01
3.02 x 10^2 = 302
2.3 x 0.01 = 0.023
Hope this helps
Step-by-step explanation:
when it comes to checking if a function is even or odd, it boils down to changing the argument, namely x = -x, and if the <u>resulting function is the same as the original</u>, then is even, if the <u>resulting function is the same as the original but negative</u>, is odd, if neither, well then neither :).
anyway, that said, let's first expand it and then plug in -x,

1/2 gallon= .75 grams
1 gallon= 1.5 grams
2 gallons = 3 grams
4 gallons = 6 grams
So
4 gallons is 6 grams
Then we add on a half which is .75 grams
6g + 0.75g = 6.75g

Answer:it costs $1150 to rent the apartment for one month.
Step-by-step explanation:
Let x represent the cost to rent the apartment for one month.
They must pay the landlord two months' rent and $500 security deposit when they sign the lease. This means that the security deposit is constant and independent of the number of months that they want to pay for.
The total amount they pay the landlord is $2800. Therefore
2x + 500 = 2800
2x = 2800 - 500 = 2300
x = 2300/2 = 1150
