f(d) = 11(1.01)^d
Part A:
f(d) = 11.79
11.79=11(1.01)^d (1.01)^d = 11.79/11 (1.01)^d = 1.071818 d = log 1.071818 /log 1.01
d = 6.97
Part B:
y- intercept is obtained when domain = 0
d = 0 ⇒ f(0) = 11(1.01)^0 = 11*1 = 11
f(d) = 11
Part C:
Average rate of change
A.f/Ad=
(f(7)-f(2))/(7-2) = (11(1.01)^7-11(1.01)^2)/5 = 0.57/5 =
Answer:
P = 7.7 C + 1.1 XC
Step-by-step explanation:
From the question, it is noted that the price of helium required to fill each of the balloons would increase by 10%. Let the current price of helium be C, so that;
10% of C = 0.1 C
The price of helium next year = C + 0.1 C
= 1.1 C
Cost of 7 small balloons = 1.1 C * 7
= 7.7 C
Cost of X large balloons = 1.1 C * X
= 1.1 XC
The total price, P for helium next year = 7.7 C + 1.1 XC
Thus, the equation to find the total price of helium that would fill the balloons next year is;
P = 7.7 C + 1.1 XC
Alright so if I do remember my math correctly, this is how it goes:
- y = -x^2 + x + 3
- x = -b/2a
- x = -1/2(-1)
- x = -1/-2, which = (1/2)
Not quite sure if this was correct, but if it was, hope this helps and you're welcome! :)
