(1.9 x 10^5)^3 = 1.9^3 x 10^15 = 6.859 x 10^15
Answer: the chairs alone would cost $358.36, and since you would already know how much the table costs you would just add it together to get $958.35
Step-by-step explanation:
Answer:
Identity is verified.
Step-by-step explanation:
We have to verify the identity 
To prove any identity we always prove one side(either left hand side or right hand side) of the equation equal to the other side.
In this identity we take the left hand side first

(as we know cos(a+b) = cosa×cosb-sina×sinb)


= - sinx ( Right hand side)
Hence identity is proved.
Answer: I think the answer would be b) 24+2x=5x
sry if it's wrong
1-(24.5/100)=0.755 which will be our multiplier
5400 x 0.755 = $4077 left in his account
5400-4077=$1323 decrease
