We need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit which is compounded semi-annually.

To solve this problem, we can use the formula for the future value of an annuity:

\(FV = P * ((1 + r)^n - 1) / r\)

Where:

FV is the future value of the annuity

P is the periodic payment or deposit amount

r is the interest rate per period

n is the number of periods

In this case, the deposit amount is $726.56, the interest rate is 6.45% compounded semi-annually, and the future value is $31,300. We need to find the number of deposits (n).

We can rearrange the formula and solve for n:

n = log((FV * r) / (P * r + FV)) / log(1 + r)

Substituting the given values:

n = log((31,300 * 0.03225) / (726.56 * 0.03225 + 31,300)) / log(1 + 0.03225)

Using a calculator or software, we find that n ≈ 9.989.

Therefore, we need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit.

Answer:

5 7/20 as a decimal is 5.35

Hope that helps. x

Answer:

Step-by-step explanation:

If your question has a big number 5 and a fraction 7/20, the 5 is going to be in the left side of the decimal, like 5.something ... the 7/20 is going to be the part on the right. If you're allowed to use a calculator just divide 7÷20 and that part goes on the right of the decimal. If you're not allowed to use a calculator then change 7/20 into something/100 ... 7/20× 5/5 gives you 35/100. That is the decimal part. It is written .35 So all together you get 5 7/20 is 5.35

To determine whether the series ∑(n=1 to infinity) 7n/n is convergent or divergent, we can apply the ratio test. The ratio test helps us determine the convergence or divergence of a series by examining the limit of the ratio of consecutive terms.

In this case, let's calculate the ratio of consecutive terms using the formula for the ratio test:

lim(n→∞) |(7(n+1)/(n+1))/((7n/n)|

Simplifying the expression, we get:

lim(n→∞) |7(n+1)/n|

As n approaches infinity, the limit evaluates to:

lim(n→∞) |7(n+1)/n| = 7

Since the limit is a finite positive value (7), which is less than 1, the ratio test tells us that the series is convergent.

However, you mentioned identifying an (term) in the series, and it seems there may be an incomplete part of the question. Please provide additional information or clarification about identifying an term in the series so that I can provide a more specific answer.

The probability of drawing a red crayon from the bag is 2/5 or 40%.

The probability of drawing a red crayon from the bag can be calculated by dividing the number of red crayons by the total number of crayons in the bag.

In this case, the bag contains a total of 8 red crayons, 4 blue crayons, 2 yellow crayons, and 6 green crayons.

So, the total number of crayons in the bag is 8 + 4 + 2 + 6 = 20.

The probability of drawing a red crayon can be calculated as follows:

Number of red crayons / Total number of crayons = 8 / 20

Simplifying this fraction gives us:

Probability of drawing a red crayon = 2 / 5

Answer:

Shape 2 and 3

Step-by-step explanation:

shape 1 is not enclosed so it cannot have area

We are given:

An even number 'n', multiplied by the next consecutive even number is 168

Solving for n:

From the given statement, we can say that:

n(n+2) = 168                      [n multiplied by the next even number 'n+2']

n² + 2n = 168

n² + 2n - 168 = 0               [subtracting 168 from both sides]

We can see that we now have a quadratic equation, solving using splitting the middle term

n² + 14n - 12n - 168 = 0

n(n + 14) -12(n + 14) = 0      [factoring out common terms]

(n-12)(n+14) = 0

Here, we can divide both sides by either (n-12) OR (n+14)

Checking the result in both the cases:

(n + 14) = 0/(n-12)                     (n-12) = 0/(n+14)

n + 14 = 0                                 n - 12 = 0

n = -14                                      n = 12

Both these values are even and since we are not told if the number 'n' is positive or negative, both 12 and -14 are the possible values of n

The total amount spent was $11.40.

To find out how much was spent, we need to add up the cost of the first cup, the cost of the refills, and the cost of the bagel, and then subtract the discount. Here's how to do it step-by-step:

1. Start with the cost of the first cup: $4.25
2. Add the cost of the refills: $2.25 + $2.25 = $4.50
3. Add the cost of the bagel: $3.15
4. Add up the total cost so far: $4.25 + $4.50 + $3.15 = $11.90
5. Subtract the discount: $11.90 - $0.50 = $11.40

So the total amount spent was $11.40.

The ratio of the radius of the larger tank to the radius of the smaller tank is approximately 1.10.

Let's assume the radius of the smaller tank is 'r'. Since the larger tank's volume is 1.20 times its height, and the volume of a cylinder is calculated as πr²h, we can set up the following equation:

1.20πr²h = 218

Similarly, for the smaller tank:

πr²h = 150

Dividing the first equation by the second equation, we get:

(1.20πr²h) / (πr²h) = 218/150  

1.20 = 218/150

To find the ratio of the radii, we can take the square root of the above ratio, as the ratio of the radii is proportional to the square root of the volume ratio. Taking the square root of both sides, we have:

√1.20 = √(218/150)  

√1.20 ≈ 1.10

Therefore, the ratio of the radius of the larger tank to the radius of the smaller tank is approximately 1.10.

Answer:

A: Function f.

Step-by-step explanation:

Let's find the maximum y-value of each function.

Function f  is given by:

\(f(x)=3\cos(2x)+4\)

Remember that the value of cosine is always between -1 and 1. In other words:

\(-1\leq \cos(x)\leq 1\)

Then assuming the greatest value for cosine, we can substitute it for one:

\(f(x)_{\text{max}}=3(1)+4=7\)

Function g is given by the graph.

Looking at the graph, we can see that the maximum y-value of g is 3.

Finally, function h is given by the table.

Looking at the table, the maximum y-value of h is -2.

Therefore, function f has the greatest maximum y-value.

Answer:

Step-by-step explanation:

The measures of triangle exists 45 45 90 then the length of the hypotenuse is 6√2 units.

Due to the fact that the triangle's legs are always the same length, d = 8. Always on the other side of the right angle is the hypotenuse. The hypotenuse of this triangle, represented by the letter e, is at its base. You must multiply the leg of a 45-45-90 triangle by the square root of two to determine the hypotenuse.

The hypotenuse of a 45°, 45°, and 90° triangle measures about two times the length of a leg.

In the right triangle ABC, AB is equal to AC

AB = AC = 6 units

BC is the hypotenuse

Applying the Pythagorean Theorem

BC² = AB² + AC²

substitute the values in the above equation, we get

BC² = 6² + 6²

Simplifying the above equation, we get

BC² = 72

BC = √72

BC = 6 √2 units

Therefore, the length of the hypotenuse is 6√2 units.
