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?
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.
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.
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?
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?
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
= 7/2 × 5/17
= 35/34
Therefore the number of spoons required to make 4 gallons
= 4 × 35/34
= 140/34
= 70/17
= 4 2/17

Can someone explain how to do this worksheet? when graphing the lines they don't seem to intersect with a UFO.
Answer:
There are 2 equations together in each box, so what you need to do is graph them both. Then see where they intersect, that will be where the ufo they shot is. For example On the first two set of equations (y=x+6 & y=-x-4) when graphed together they intersect at (-5,1) which is where ufo 6 is. Meaning they shot Ufo 6
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.
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
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.

Answer:
7384.46330241 or 7384.5
Step-by-step explanation:
first to find the Y you had to use distributive property
1. 9(1+0.03) = 9+0.27
2. 9+0.27= 9.27
3. 9.27 to the 4th power will be 7384.46330241 or 7384.5
Answer:
10.13
Step-by-step explanation:
Remark
The correct way to do this is to add what is inside the brackets (the terms are alike so you can do that) and raise the result to the forth power. Then you multiply by 9.
Solution
1 + 0.03 = 1.03
1.03 ^4 = 1.1255
1.1255 * 9 = 10.13

Answer:
Remember that the roots are the values of the variable when the expression equals 0.
a: 4 + 3 = 7 and 4*3 = 12 so we have (x + 3)(x + 4) with roots -3, -4
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
d: -7+-4 = -11 and -7*-4=28 so we have (y-4)(y-7) with roots 4, 7

Given: R(-2, 0), S(-3, 1), T(0, 1), U(-5, 3) and V(4, 3).
Prove: ΔRST ~ ΔRUV
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
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
