Answer:

-1/4 x 4 = -1

Step-by-step explanation:

:)

That person have $ 573.79 in his account balance after 8 years.

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

Here, Principal = $ 310

          Rate of interest = 8%

          Time = 8 years

We know,

Amount = P (1 + i )ⁿ

              = 310 X (1 + 0.08)⁸

              = 310 X 1.85

             = $ 573.79

Thus, that person have $ 573.79 in his account balance after 8 years.

Answer:

94 square inches.

Step-by-step explanation:

Surface area is the area around a surface. Thus, in order to calculate the surface area of a rectangular prism, we just need to add up the different faces of it.

There are 2 5x4 faces, 2 3x5 faces, and 2 4x3 faces.

Thus, we get 2*20 + 2*15 + 2*12 = 40 + 30 + 24 = 94 square inches.

Using an exponential function, it is found that it takes 5.42 years for the car to halve in value.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, the car depreciates 12% a year in value, hence r = 0.12 and the equation is given by:

[tex]A(t) = A(0)(0.88)^t[/tex].

It halves in value at t years, for which A(t) = 0.5A(0), hence:

[tex]A(t) = A(0)(0.88)^t[/tex]

[tex]0.5A(0) = A(0)(0.88)^t[/tex]

[tex](0.88)^t = 0.5[/tex]

[tex]\log{(0.88)^t} = \log{0.5}[/tex]

[tex]t\log{0.88} = \log{0.5}[/tex]

[tex]t = \frac{\log{0.5}}{\log{0.88}}[/tex]

t = 5.42.

It takes 5.42 years for the car to halve in value.

Answer:

[tex]\alpha^3-\beta^3 = \frac{28}{3}\sqrt{\frac{5}{3}}[/tex]

Step-by-step explanation:

The value of a³-B³ from the given quadratic equation is 12.05.

The roots to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

Given that, a and B are the roots of the equation 3x²+6x-2=0

By comparing 3x²+6x-2=0 with ax²+bx+c=0, we get a=3, b=6 and c=-2

The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

Now, substitute a=3, b=6 and c=-2 in quadratic formula

That is, x = [-6 ±√(6² - 4×3×(-2))]/2×3

= [-6 ±√60]/6

= (-6±2√15)/6

= (-3±√15)/3

So, a=(-3+√15)/3 and B=(-3-√15)/3

Now, a³-B³ = [(-3+√15)/3]³- [(-3-√15)/3]³

= 12.05

Therefore, the value of a³-B³ from the given quadratic equation is 12.05.

Answer:

SA = 90 in²

Step-by-step explanation:

given 2 similar shapes with sides in ratio a : b , then

ratio of areas = a² : b²

ratio of volumes = a³ : b³

Given ratio of volumes = 64 : 27 , then

ratio of sides = [tex]\sqrt[3]{64}[/tex] : [tex]\sqrt[3]{27}[/tex] = 4 : 3

then ratio of areas = 4² : 3² = 16 : 9

let x be the surface area of the smaller box then by proportion

[tex]\frac{x}{9}[/tex] = [tex]\frac{160}{16}[/tex] = 10 ( multiply both sides by 9 )

x = 90

surface area of smaller box is 90 in²

67.5 square inches is the surface area of a similar shoe box if its volume is only 27 cubic inches

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that  shoe box has a volume of 64 cubic inches and a surface area of 160 square inches.

We have to find the  surface area of a similar shoe box if its volume is only 27 cubic inches

Lets form a proportional equation

64/160 = 27/x

Apply cross multiplication

64x=160(27)

64x=4320

Divide both sides by 64

x=4320/64

x=67.5

Hence, 67.5 square inches is the surface area of a similar shoe box if its volume is only 27 cubic inches

your rate of change is $3.25, since you get charged $3.25 per bouquet.

The rate of change is $3.25 and the y-intercept is $30.

A mathematical statement that relates two algebraic expressions by an equal sign.

The Tram fancy balloons has offered a down payment of $30

and the charge per bouquet is $3.25

Let x represent the number of bouquets

The equation for the total cost can be formed is

y = 30 + 3.25*x

The perimeter of the water wheel  [tex]8\sqrt{10}[/tex]

The correct option is (A)

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. To derive the formula, let us consider two points in 2D plane A( x, a) and B(y, b).

So, the distance between two points be: [tex]\sqrt{(y-x)^{2}+(b-a)^{2}}[/tex]

As water wheel is designed in the shape of regular octagon.

To find the perimeter of the  water wheel.

Since the water wheel is in the shape of regular octagon all sides are equal.

Using Distance Formula,

D= [tex]\sqrt{(4-3)^{2}+(0-3)^{2}}[/tex]

  = [tex]\sqrt{10}[/tex]

So, the side of regular octagon will be [tex]\sqrt{10}[/tex].

Perimeter of Regular Octagon = 8 x side
