Answer:

17

Step-by-step explanation:

Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. It takes 17 year for the value of the account to reach $12,110.

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Compound Interest =P(1+r/n)^rt

Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. for the value of the account to reach $12,110 we need to find the time it takes.

The principal amount = $7,200

Rate = 3.1%

Compound Interest = [tex]P(1+r/n)^{rt}[/tex]

                      12,110  =  [tex]7200(1+3.1/12)^{3.1t}[/tex]

                            t = 17

Thus, for the value of the account to reach $12,110 the time taken is 17.

Answer:

5/18, 13/18

Step-by-step explanation:

The basic probability of anything is Specific Outcome / Total Outcomes

The specific outcome here is pulling a purple marble. We see there are 5 purple marbles therefore there are 5 ways to get them. The total outcomes are the total number of marbles which is 18. Therefore, the answer is 5/18

The complement of a probability is 1 minus the original probability, so, it would be 1 - 5/18 here getting us 13/18 as the answer.

x^2 = 12 (y - 2)

Step-by-step explanation:

how to explian

The equation that represents a parabola is x^2 = 12(y-2).

Parabola is a open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is the locus of a point that is equidistant from a fixed point called the focus (F), and the fixed-line is called the directrix.

For the given situation,

A parabola with a focus of (h,k+p) is (0, 5) and

A directrix of y = (k-p) = -1

Here,

[tex]k+p=5\\k-p=-1[/tex]

On solving these equations,

[tex]k=2, p =3[/tex]

The general equation of parabola is

[tex](x-h)^{2} =4p(y-k)[/tex]

On substituting all the values,

⇒ [tex](x-0)^{2} =4(3)(y-2)[/tex]

⇒ [tex]x^{2} =12(y-2)[/tex]

Hence we can conclude that the equation that represents a parabola is x^2 = 12(y-2).

The shaded region has an area of 1400 square units

Step-by-step explanation:

Area of Compound Shapes

We are given a shape and it's required to calculate its area. The shape can be divided into three rectangles as shown in the figure attached below.

The lengths of these rectangles are x, y, and z.

The value of x can be calculated as:

x = 60 - 15 - 10 = 35

Similarly:

y = 60 - 15 = 45

z = y = 45

The first rectangle has dimensions of x by 10, thus its area is:

A1 = 35*10 = 350

The second rectangle has dimensions of 60 by 10:

A2 = 60*10 = 600

The third rectangle has dimensions y by 10:

A3 = 55*10 = 450

The shaded area is:

A = 350 + 600 + 450 = 1400

The shaded region has an area of 1400 square units

Answer:

WY = 28

Step-by-step explanation:

Using the pythagorean theorem, we can find out the measures of lenghts WX and YX individually.

VX^2 = VW^2 + WX^2

ZX^2 = ZX^2 + XY^2

Substitute

400 = 256 + WX^2

400 = 144 + XY^2

Simplify

WX^2 = 144

XY^2 = 256

WX = 12

XY = 16

WY = 28
