Answer:

You can use the formula 500 * 1.03^x to solve for any year.

year 4 is 500 * 1.03^(4) = 562.75

year 6 is 500 * 1.03^(6) = 597.03

Year 7 is 500 * 1.03^(7) = 614.94

Step-by-step explanation:

The amount is increasing, and there are two main ways for that to happen. Addition and multiplication. So let's see if it keeps getting the same amount added or multiplied.

0 to 1 goes from 500 to 515, so 15 is added. but 15.45 is added from 1 to 2, so we can't just do simple addition.

using multiplication 0 to 1 has 1.03 multiplied. if you multiply by it again you do get 530.45, so we have established what is happening.

You can use the formula 500 * 1.03^x to solve for any year.

so year 4 is 500 * 1.03^(4) = 562.75

year 6 is 500 * 1.03^(6) = 597.03

Year 7 is 500 * 1.03^(7) = 614.94

A playground is located on a triangular piece of land. Two sides of the playground are 157 feet long and they meet at an angle o

Answer:

$5,671.84

Step-by-step explanation:

To find the third side, we can use the law of cosines:

c^2 = a^2 + b^2 - 2ab*cos(theta)

c^2 = 157^2 + 157^2 - 2*157*157*cos(65)

c^2 = 28463.7649

c = 168.71 feet

The perimeter of the playground is:

P = 157 + 157 + 168.71 = 482.71 feet

If each foot costs $11.75, the final cost is:

Cost = 482.71 * 11.75 = $5,671.84

Factor the polynomial: – x3 - 4x2 - 5x

Alinara [238K]

Answer:

$-x3-4x2-5x=-x(x^2+4x+5)$

Step-by-step explanation:

we are given the polynomial as

$-x3-4x2-5x$

here we can see that the GCF of $-x^3$ , $-4x^2$ and $-5x$ is

$-x$

Hence we take it outside the bracket

$-x(x^2+4x+5)$

The polynomial within the bracket $x^2+4x+5$ can not be factorized further , hence this would be our final answer.

AysviL [449]

Answer:

We can create a one-variable equation and solve for x.

we set 35.25+0.11x equal to 14.25+0.32x

35.25+0.11x=14.25+0.32x

then we just solve for x to get 100

Categorize the following variables as being qualitative or quantitative: (relevant section):

FrozenT [24]

Answer:

1. Quantitative

2. Quantitative

3. Qualitative

4. Qualitative

5. Quantitative

Step-by-step explanation:

A variable is quantitative if it assumes numerical values, for example 1,2,3.

If it assumes "labels", for example good or bad, it is qualitative.

1. Rating of the quality of a movie on a 7-point scale

It assumes numerical values, for example, 1,2,3,...

So it is quantitative

2. Age

It assumes numerical values, for example, 1,20,35,...

So it is quantitative

3. Country you were born in

Descriptive, such as Brazil, USA, Colombia, ...

So it is qualitative.

4. Favorite Color

Descriptive, such as black, brown, red, blue

So it is qualitative

5. Time to respond to a question

It assumes numerical values, for example, 1,20,35,...

So it is quantitative
