Answer:
The highest possible price of a sweater is $28.33
Step-by-step explanation:
We already know that price
of jeans is $35.Let's say Mrs.Smith buys 3 sweaters for
dollars each, and since her budget is $120 we have the inequality:

Therefore

Thus the maximum price of a sweater is $28.33
Answer: C) 127, 152.4, 182.88, 219.456,...
Step-by-step explanation:
You can only find the sum of an infinite geometric sequence if it converges.
One criterion to see if the series converges is if:
aₙ < aₙ₋₁
This means that, as n increases, the value of the terms decreases.
This means that as n tends to infinity, aₙ tends to zero.
Then we only can find the sum of those series where the terms are decreasing.
in A, B and D the terms are decreasing, then we can find the sum of those 3 series.
Now in the case of C, the terms are increasing, then we can not find the sum of that series.
The correct answer is summer because of heat
Answer:
21
Step-by-step explanation:
y = 3x + 9
y = -3x + 12
y=21
The decay factor of the exponential function given in the table is of
.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, we have that when x increases by 1, y decreases by a factor of 3, hence the decay rate r is found as follows:
