(5^3+7x-8)+(2^3-5x^3-5x^2-x+3) in standard form

Answer: Graph the inequality by finding the boundary line, then shading the appropriate area. In slope intercept form its y>-6 + 2x/3. Graph the y intercept -6, then use rise/run and go up 2 points and then to the right 3 points. Then shade the upper right because it is a greater sign and make the lines dashed.

Solution :

Given :

The rate of change of y is proportional to y.

Therefore, [tex]$\frac{dy}{dt} \propto y$[/tex]

[tex]$\frac{dy}{dt} = k y$[/tex] ,             where k is the proportionality constant

[tex]$\frac{dy}{y}=k \ dt$[/tex]

Taking integration on both the sides,

[tex]$\int \frac{dy}{y}=\int kdt$[/tex]

[tex]$\int \frac{dy}{y}=k\int dt$[/tex]

[tex]$\ln |y| = kt+C$[/tex],    where C is the integration constant

[tex]$y=e^{kt+C}$[/tex]

[tex]$y=e^{kT}e^C$[/tex]

[tex]$y(t)=C_1e^{kt}$[/tex]  ....................(1)

When t = 0, y = 2, so

[tex]$2=c_1e^{k\times 0}$[/tex]

[tex]$2=c_1e^{ 0}$[/tex]

[tex]$2=C_1$[/tex]

From equation (1),

[tex]$y=2e^{kt}$[/tex] ........................(2)

when t = 2, y = 4

[tex]$4=2e^{k\times 2}$[/tex]

[tex]$e^{2k}=\frac{4}{2}$[/tex]

[tex]$e^{2k}=2$[/tex]

[tex]$2k= \ln(2)$[/tex]

[tex]$k=\frac{1}{2} \ln(2)$[/tex]

From (2),

[tex]$y=2e^{\frac{1}{2}\ln(2)t}$[/tex]

[tex]$y=2e^{\frac{t}{2}\ln(2)}$[/tex]

[tex]$y=2e^{\ln(2)^{t/2}}$[/tex]

[tex]$y=2.2^{t/2}$[/tex]

When t = 3,

[tex]$y = 2 . 2 ^{3/2}$[/tex]

[tex]$y=2[(\sqrt2)^2]^{3/2}$[/tex]

[tex]$y= 2. 2\sqrt2$[/tex]

[tex]$y=4 \sqrt2$[/tex]

Answer:

2.5

Step-by-step explanation:

8 times 4 is 32, and 80/32 is 2.5. When you have to find another measurement and you know 2 of them, you just have to divide the total of the 2 measurements with the volume. it would be 2.5 feet as the height.

Answer:

We have the function:

f(x) = 2*sin(x) - 3

To graph this type of functions is useful to understand the parts of the function.

A general one is written as:

g(x) = A*sin(w*x + p) + M

where:

A is the amplitude

w is the angular frequency.

p is the phase

M is the midline.

Then in this case we have an amplitude of 2, an angular frequency of 1, a phase of 0 radians and the midline y = -3

Now we can evaluate the function in different points and (knowing how a sine function behaves) connect them, the graph will look something like this:

B. 2x^4-11x^3+7x^2+5x-3

Answer:

Step-by-step explanation:

7x + 8y = -5

       8y = -7x - 5

Divide the whole equation by 8

[tex]\frac{8y}{8}=\frac{-7x}{8}-\frac{5}{8}\\\\y =\frac{-7}{8}x-\frac{5}{8}[/tex]

Parallel lines have same slope

Slope of the parallel line = (-7/8)

Slope of the line perpendicular to this line = -1/m  = -1 ÷ (-7/8)

                                                                      [tex]= (-1)*\frac{8}{-7}\\\\= \frac{8}{7}[/tex]

area of triangle = 1/2 x 2 x 6 sq yards

multiply by $2/sq yard

Answer: $24

Step-by-step explanation:

The formula for a triangle is 1/2 times base times height

so 0.5 x 4 x 6

0.5 x 4 = 2

2 x 6 = 12

12 x $2 = 24

so you charge $24 dollars

Answer:

y=2x+5

Step-by-step explanation:

To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)

So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2

Slope = 2, now find b

So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5

Put it all together y = 2x + 5

Answer:

The slope of the line is 5

Step-by-step explanation:

When we talk of the slope of a straight line graph, we refer to the rate at which the values on the y-axis changes as a ratio of the changes we have on the x-axis

Now, from the question, number of hours is placed on x-axis, while we have the amounts on the y-axis

having $5 per hour means the rate of change of what is earned to number of hours worked is 5 and this is the slope of the line

Answer:

yellow area = 5.37 ft²

Step-by-step explanation:

area of square = L x W = 5 x 5 = 25 ft²

radius = 2.5 ft

area of circle = PiR² = (3.14)(2.5²) = 19.63 ft²

25 - 19.63 = 5.37 ft²

The area of the yellow region is 5.375 square feet.

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

Given that, the side of a square = 5 feet and radius of a circle = 2.5 feet.

Here, area of a square = side²

= 5²

= 25 square feet

Area of a circle = πr²

= 3.14×2.5²

= 19.625 square feet

So, the area of the yellow region = 25-19.625

= 5.375 square feet

Therefore, the area of the yellow region is 5.375 square feet.

Answer:

14 tons of sugar

$9603.5

Step-by-step explanation:

For what amount of sugar do the two companies charge the same?

What is the cost when the two companies charge the same?

Let

x = ton of sugar

Company A:

7500 + 150.25x

Company B:

7143 + 175.75x

1. Equate company A and company B

7500 + 150.25x = 7143 + 175.75x

7500 - 7143 = 175.75x - 150.25x

357 = 25.50x

x = 357/25.50

x = 14 tons of sugar

2. Cost when both companies charge the same

Company B:

7143 + 175.75x

= 7143 + 175.75(14)

= 7143 + 2460.5

= 9603.5

Company B = $9603.5

Company A:

7500 + 150.25x

= 7500 + 150.25(14)

= 7500 + 2103.5

= 9603.5

Company A = $9603.5
