Brianna is going to invest in an account paying an interest rate of 5.2% compounded daily. How much would Brianna need to invest, to the nearest ten dollars, for the value of the account to reach $6,600 in 11 years?

Answers

Answer:

3398.1761

Step-by-step explanation:

Using compound interest relation:

A = P(1 + r/n)^nt

5.2 / 100 = 0.052

n = 365 * 12 = 4380

6000 = P(1 + 0.052/4380)^4380*11

6000 = P(1.0000118)^48180

6000 = 1.7656530P

P = 6000/ 1.7656530

P = 3398.1761

Write a polynomial in standard form that represents the area of the shaded region.

Answers

Answer:

[tex]A=p^2-2p-3[/tex]

Step-by-step explanation:

The area for a triangle is given by:

[tex]\displaystyle A=\frac{1}{2}bh[/tex]

The base is p + 1 and the height is 2p - 6. Therefore:

[tex]\displaystyle A=\frac{1}{2}(p+1)(2p-6)[/tex]

Simplify the second term:

[tex]\displaystyle A=(p+1)(\frac{1}{2})(2p-6)=(p+1)(p-3)[/tex]

Distribute:

[tex]A=p(p-3)+1(p-3)[/tex]

Distribute:

[tex]A=p^2-3p+p-3[/tex]

Combine like terms:

[tex]A=p^2-2p-3[/tex]

A family has a newborn baby and decides to invest $300 into an account that will earn interest. They plan to give her the full amount of money in the account on her 18th birthday. They have two choices: Option 1: An account that grows by 12% each year Option 2: An account that grows by $30 each year. Which option will result in a better 18th birthday gift? Justify your choice and explain your reasoning.​

Answers

Option 1 is better. 12% of $300 is $36, so even in just the first year, it grows by $6 more than if they picked the other option. I hope this helps :)

A rectangular prism and it’s dimensions are shown in the diagram. What is the total surface are of the rectangular prism in square feet?

Answers

Answer:78.5

Step-by-step explanation:

The total surface area of the rectangular prism shown is 78.5 feet².

What is Rectangular Prism?

Rectangular prism is a three dimensional shape which consist of six faces. The two faces are at the top and bottom and the other faces are lateral faces.

The surface area of a rectangular prism can be calculated as,

Surface area = 2 (lw + wh + lh)

Here l is the length, w is the width and h is the height of the rectangle.

From the figure,

l = 4.5 feet

w = 4 feet

h = 2.5 feet

Surface area = 2 [ (4.5 × 4) + (4 × 2.5) + (4.5 × 2.5)]

                     = 2 [18 + 10 + 11.25]

                     = 2 × 39.25

                     = 78.5 feet²

Hence the surface area is 78.5 feet².

It takes 3 1/2 spoons of chocolate syrup to make 3 2/5 gallons of chocolate milk. How many spoons would it take to make 4 gallons of chocolate milk?

Answers

Answer:

4 2/17

Step-by-step explanation:

It takes 3 1/2 spoons of chocolate syrup to make 3 2/5 gallons of chocolate milk

3 1/2= 3 2/5

7/2= 17/5

1 gallon = 7/2÷17/5

Therefore the number of spoons required to make 4 gallons

= 4 × 35/34

= 140/34

An artist frames his rectangular artwork. The length of his art is 3 times the width, w. How can he represent the perimeter of the art? Match each reason on the left to the expression it describes.

Answers

Answer:

Perimeter = 8w

Step-by-step explanation:

Let the width of the rectangular framework be w.

Length = 3w

We know that the perimeter of a rectangular shaped object is given by :

P = 2(l+w)

Substitute all the values in the above formula,

Perimeter = 2(3w+w)

= 2(4w)

= 8w

So, the perimeter of the art be 8w.

Find the total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years

Answers

Answer:

$7400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

I = 5000 × 0.04 × 12 = 2400

I = $ 2,400.00

The simple interest accumulated

on a principal of $ 5,000.00

at a rate of 4% per year

for 12 years is $ 2,400.00.

The total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years is $2400 and this can be determined by using the simple interest formula.

Given :

The total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years.

The total amount due on a simple interest loan can be determined by using the simple interest formula which is given by the equation:

[tex]\rm I = PRT[/tex]

Given that time, T = 12 years

Rate, R = 4% = 0.04

Principal amount, P = $5000

Now, put the value of P, R, and T in the equation (1).

[tex]\rm I = 5000\times 0.04 \times 12[/tex]

I = $2400

The total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years is $2400.

b: -4 + -2 = -6 and -4*-2=8 so we have (t-2)(t-4) with roots 2, 4

c: 2*-4 + 6 = -2 and -4*6=24 so we have (2n+6)(n-4) with roots -3, 4

This is a simple transformation, DILATION.

Upon graphing this out, or finding the side lengths of the triangle, you will find that side length RU is triple of that of RS. This is the same for RV and RT. Dilation transformations don't change angles, only side lengths, and for the whole triangle, which means that this transformation will still equate the triangles to each other.

If the area of a sector is 100 ft^2 and the radius of the circle is 22 ft what is the central angle measure for that sector and what is the length of the arc

Answers

Answer:

[tex]\displaystyle \theta=0.413\ rad[/tex]

L= 9.086 feet

Step-by-step explanation:

Area of a Circular Sector

Given a circle of radius r, the area of a circular sector defined by a central angle θ (in radians) is given by

[tex]\displaystyle A=\frac{1}{2}r^2\theta[/tex]

And the length of the arc is:

[tex]L=\theta r[/tex]

We know the area of the sector is 100 square feet and the radius is r=33 ft, thus:

[tex]\displaystyle 100=\frac{1}{2}r^2\theta[/tex]

Solving for θ:

[tex]\displaystyle \theta=\frac{200}{r^2}[/tex]

[tex]\displaystyle \theta=\frac{200}{22^2}[/tex]

[tex]\displaystyle \theta=0.413\ rad[/tex]

The arc length is:

[tex]L=0.413* 22[/tex]

L= 9.086 feet
