Step-by-step explanation:

cook time = 65 min + 11 min + 60 seconds + 30 seconds

= 65 min + 11 min + 1.5 minute

cook time = 77.5 minutes or: 1 hour, 17 minutes and 30 seconds.

For food to be ready by 4PM:

4PM - 1 hour, 17 minutes and 30 seconds = when to put food in

put food in = 2:42:30 PM

An exponential equation that passes through the points (2,1.8) and (5,14.4) is y = (0.6708)2ˣ

Exponential equation:

If you have two points, (x1, y1) and (x2, y2), you can define the exponential function that passes through these points by substituting them in the equation

y = abˣ

and solving for a and b.

In general, you have to solve this pair of equations:

y1 = abˣ¹ and y2 = abˣ²

Given,

The points (2,1.8) and (5,14.4).

Here we need to find the exponential equation that passes through the points.

This yields the following pair of equations:

1.8 = ab²

14.4 = ab⁵

If you divide the second equation by the first, you get

b³ = 14.4/1.8

b³ = 8

b = ∛8

b = 2

so b = 2. It's possible for b to also be equal to -2, but in this case, assume it's positive.

Now, we can substitute this value for b in either equation to get a. It's easier to use the first equation, so:

1.8 = a² x (2)²

1.8 = a²  x 4

a²  = 1.8/4

a²  = 0.45

a = √0.45

a = 0.6708

Therefore, the exponential form of the equation is,

y = (0.6708)2ˣ

Answer:

[tex]\large\text{$y& = e^{\frac{1}{3}x^3+x+\text{C}}$}[/tex]

Step-by-step explanation:

Given differential equation:

[tex]\dfrac{\text{d}x}{\text{d}y}=\dfrac{1}{y(x^2+1)}[/tex]

Rearrange the equation so that all the terms containing y are on the left side, and all the terms containing x are on the right side:

[tex]\begin{aligned}\implies \dfrac{\text{d}x}{\text{d}y}&=\dfrac{1}{y(x^2+1)}\\\\(x^2+1)\;\dfrac{\text{d}x}{\text{d}y}&=\dfrac{1}{y}\\\\(x^2+1)\;\text{d}x}&=\dfrac{1}{y}\;\text{d}y\\\\\dfrac{1}{y}\;\text{d}y&=(x^2+1)\;\text{d}x}\end{aligned}[/tex]

Integrate both sides:

[tex]\begin{aligned}\implies \displaystyle \int \dfrac{1}{y}\;\text{d}y &= \int (x^2+1)\;\text{d}x}\\\\\int \dfrac{1}{y}\;\text{d}y &= \int x^2\;\text{d}x}+\int 1\;\text{d}x}\\\\\ln y & = \dfrac{1}{3}x^3+x+\text{C}\\\\e^{\ln y} & = e^{\frac{1}{3}x^3+x+\text{C}}\\\\y& = e^{\frac{1}{3}x^3+x+\text{C}}\\\\\end{aligned}[/tex]

Stocks and bonds both have costs, risks, and returns associated with them. Bonds offer an interest payment through a maturity date while stocks may offer dividends that will grow until it is sold.

Over the long term, stocks have the highest potential for growth for investors. Investors who have chosen to hold onto stocks for an extended length of time have typically been rewarded with robust, profitable returns. However, stock prices fluctuate both up and down.

An IOU-like debt security called a bond. Bonds are issued by borrowers to attract capital from investors ready to extend a loan to them for a specific period of time. When you purchase a bond, you are making a loan to the issuer, which could be a corporate, government, or municipality.

A dividend is a payment made by a corporation to its shareholders that is decided by the board of directors. Dividend payments are frequently made quarterly and might take the form of cash payments or stock reinvestments.

The length and width of the rectangular box are 13 ft and 6 ft respectively.

The length of the batter's box on a softball field is 1 ft more than twice the width.

The area of the batter's box is 78 ft².

The length and width of the rectangular batter's box can be found as follows:

Therefore,

area of a rectangle = lw

where

Therefore,

area of the rectangular box = 78 ft²

l = 1 + 2w

(a) The area of the triangle = 6 cm squares

(b) The area of the whole shape = 76 cm squares

The shape given is formed by a triangle and a rectangle.

First we need to find the area of the triangle.

Height of the triangle = 3 cm

Base of the triangle = 4 cm

Area of the triangle = 1/2 x base x height

                                 = 1/2 x 4 x 3

                                 = 6 cm squares

Area of the whole shape = Area of the triangle + Area of the rectangle

Length of the rectangle = 10 cm

Width of the rectangle = 7 cm

Area of the rectangle = length x width

                                    = 10 x 7

                                    = 70 cm squares

Therefore, area of the whole shape = 6 + 70

Explanation:

Let x represent the number of defective cars.

Assuming that number of defective cars are uniformly distributed in the total number of cars, we can go ahead and solve for x by setting up proportion as shown below;

As a result of the sequences, the numbers for the first equation are 31,37,43, 64,128,256, and 37,42,47 for the second and third equations, respectively.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6. An arithmetic progression is another name for an arithmetic sequence.

A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

so for the first equation:

we see the common difference is constant :

second term/third term - first term/second term =7-1 or 13-7

                        =6

the next three terms in this series would be calculated by adding the common difference to consecutive last terms  =31,37,43

for the third equation

the common difference is a constant:

second term-first term=5

the next three terms in this series would be calculated by adding the common difference to consecutive last terms  =37,42,47

for the second equation we don't see a constant value as a common difference ,then we conclude that it is a Geometric progression

difference in series = second term/first term

                              =4/2

                              =2

so for the three consecutive terms we will multiply the last consecutive terms by 2=64,128,256

Therefore the numbers for First equation are 31,37,43 for the second equation are 64,128,256 and third equation are 37,42,47

The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions. The word equation and its cognates can have slightly different meanings in different languages. For instance, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign, whereas in French, an equation is defined as containing one or more variables.

The equation's solutions are the values of the unknown variables that satisfy the equality, which are often referred to as the variables for which the equation must be solved.

let the number be x .

9 times the number is = 9x

5 times the number added to 3 is

(x + 3) × 5

Now let us set up an equation and find that number :

(x + 3) × 5 = 9x - 13

Simplifying the given equation we get :

5 (x + 3) = 9x - 13

5x + 15 = 9x - 13

5x - 9x = - 13 - 15
