Mrs. Smith decides to buy three sweaters and a pair of jeans. she had $120 in her wallet. if the price of jeans is $35, what is
mylen [45]

Answer:

The highest possible price of a sweater is $28.33

Step-by-step explanation:

We already know that price j of jeans is $35.Let's say Mrs.Smith buys 3 sweaters for p dollars each, and since her budget is $120 we have the inequality:

3p+j\leq 120\\ \\\\=3p+35\leq 120

Therefore

p\leq 28.33

Thus the maximum price of a sweater is $28.33

Which infinite geometric series can you NOT find the sum?
Oksanka [162]

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.

A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 2. The second column is labeled f (x)
telo118 [61]

The decay factor of the exponential function given in the table is of \frac{2}{3}.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

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:

1 - r = \frac{1}{3}

r = 1 - \frac{1}{3}

r = \frac{2}{3}
