Answer a = 5 and b = 2.
Procedure
Initially means x = 0, then
5 = a*b^0 = a*1 = a, then a = 5
When x = 1, the height is the double of 5, i.e 10 and
10 = a.b^1 = a.b ⇒ b = 10/a = 10/5 = 2
The a = 5 and b = 2, so the equation is y =5(2)^x
Answer:
1.17B
Step-by-step explanation:
Katie and her friends will pay 17% of the bill, B.
Therefore, we have to add 17% of B to B to find how much they will pay:
17/100 * B = 0.17B
Therefore, the total bill will be:
Bill + tip
= B + 0.17B = 1.17B
The expression that represents the total bill they will pay is 1.17B
Answer:
s=22.17
Step-by-step explanation:
v/r=u/s
18/19=21/s
18s=21(19)
18s=399
18s/18=399/18
s=22.17
Answer:
q = 
Step-by-step explanation:
given
qrv + 11 = 30 ( subtract 11 from both sides )
qrv = 19 ( divide both sides by rv )
q =
