Answer:
X would be 1,000
Step-by-step explanation:
Answer:
- (g/d, initial, factor, rate)
- (g, 45, 1.05, 5%)
- (d, 50, 0.70, -30%)
- (g, 90, 1.42, 42%)
- (d, 120, 0.45, -55%)
Step-by-step explanation:
Exponential functions all have the form ...
f(x) = (initial value)(growth factor)^x
where (growth factor) is defined as ...
(growth factor) = (1 + growth rate) ⇒ growth rate = growth factor - 1
__
If the growth rate is negative (growth factor is less than 1), then it is decay, rather than growth. Growth rate is often expressed as a percentage. A growth rate of a negative amount may be reported as a decay rate of a positive amount. (Above, we have kept the decay rates negative to reinforce the fact that they are decay. <em>Your grader may expect these values to be positive</em>.)
_____
So, to fill in the table, compare the given functions to the form above. The results are listed in the answer section above.
Answer:
8
Step-by-step explanation:
Your son is half your age minus 9, so half of 34 is 17. 17 - 9 = 8
Answer:16 and 1/2 feet
Step-by-step explanation:
Put 3x in for y, so the equation will be 3x=2x-7. Then solve. once you find “x”, plug it back into one of the original equations. And then you have x and y
