You cook a turkey until the internal temperature reaches 180°f. the turkey is placed on the table until the internal temperature reaches 100°f, and it can be carved. when the room temperature is 72°f, the cooling rate of the turkey is $r=0.067$ . how long do you have to wait until you can carve the turkey? use newton's law of cooling to solve the problem. round your answer to the nearest whole minute.

Answers

Answer 1

The newton's law of cooling is used to determine the waiting time

You will have to wait for 20 minutes to carve the turkey

How to determine the time?

By newton's law of cooling, we have:

[tex]T = (T_o - T_R) e^{-rt} + T_R[/tex]

From the question, we have:

T = 100°f ---- The serving temperature

To = 180°f --- The initial temperature

TR = 72°f ----- the room temperature

r = 0.067 -- the cooling rate

So, we have:

[tex]T = (T_o - T_R) e^{-rt} + T_R[/tex]

[tex]100 = (180 - 72) e^{-0.067t} + 72[/tex]

Subtract 72 from both sides

[tex](180 - 72) e^{-0.067t} = 28[/tex]

Evaluate the difference

[tex]108 e^{-0.067t} = 28[/tex]

Divide both sides by 108

[tex]e^{-0.067t} = 0.25923[/tex]

Take the natural logarithm of both sides

[tex]-0.067t = -1.3500[/tex]

Divide both sides by -0.067

[tex]t = 20.149[/tex]

Approximate

[tex]t = 20[/tex]

Hence, you will have to wait for 20 minutes to carve the turkey

Based on the calculations, the radius of this circle with the given equation is equal to 5 units.

Given the following data:

[tex]x^2+y^2+8x-6y+21=0[/tex]

The equation of a circle.

Mathematically, the standard form of the equation of a circle is given by;

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where:

h and k represents the coordinates at the center.r is the radius of a circle.

Expanding the equation, we have:

[tex]x^2+y^2-2hx-2ky+(h^2+k^2-r^2)=0\\\\r=\sqrt{h^2+k^2}[/tex]

Comparing the terms, we have:

[tex]-2hx = 8x\\\\-2h=8\\\\h=\frac{8}{-2}[/tex]

h = -4

[tex]-2ky = -6y\\\\-2k=6\\\\k=\frac{6}{-2}[/tex]

k = 3.

Now, we can determine the radius:

A camera is mounted on a tripod feet high at a distance of feet from​ george, who is feet tall. look at the model to the right. if the camera lens has angles of depression and elevation of ​, will​ george's feet and head be seen by the​ lens? if​ not, how far back will the camera need to be moved to include​ george's feet and​ head?

Answers

To capture his feet and head, the camera will need to be moved at least one foot backward. This is an Angles of Elevation and Depression theorem exercise.

What is the Angle of Elevation Theorem?

The angle of elevation is the angle between the line of sight and the horizontal line when an observer looks up. While the Angle of Depression refers to the angle that is formed when the observer looks down.

The formulas are given as:

tan θ = y/x  ⇒      θ = tan -1 (y/x).  

How to calculate the distance required for the camera to capture Geroge completely

Let us assume that x is the distance in feet that the tripod must be moved back.

Recall that the angle of depression and elevation as given in the question (full version attached) is 20°

The height of the Tripod is 4 feet, at a distance of 10 feet, therefore,

tan (20°) * (10 + x) = 4

x =4/tan (20°)-10

x= 4/(10.989909678 - 10)

x = 0.9899

x ≈ 1 feet.

Hence the camera must be moved back about 1 feet to capture Geroge..

To this end, the following information has been assembled: collections on sales: 60% in month of sale 30% in month following sale 10% in second month following sale the accounts receivable balance on january 1 of the current year was $70,000, of which $50,000 represents uncollected december sales and $20,000 represents uncollected november sales. The total cash collected during january by lagrange corporation would be:

Answers

Assuming $20,000 represents uncollected november sales. The total cash collected during january by lagrange corporation would be:$331.500.

Total cash collected

First step

Total Credit Sales in December= $50,000/40%

Total Credit Sales in December= $125,000

Second step

Total cash collected during January = Cash sales of January + (60% x Credit sales of January) + (30% x Credit sales of December)+ Uncollected November sales

Let plug in the formula

Total cash collected during January = $70,000 + (60% x $340,000) + (30% x $125,000) + $20,000

Total cash collected during January=$70,000+204,000+37,500+$20,000

Total cash collected during January=$331,500

What is the volume of the cone? use π ≈ 3. 14. 12. 56 cubic units 18. 84 cubic units 20. 93 cubic units 25. 12 cubic units

Answers

Answer:

Explanation:

the following formula is used to find the volume of a cone

V - volume = πr²h/3

where π = 3.14, r - radius and h - height

the height hasnt been directly given

we can find height using Pythogoras theorem for the right angled triangle given

4² + h² = 5²

16 + h² = 25

h² = 25 - 9

h² = 9

h = 3

height = 3

diameter is 4, therefore radius - diameter / 2 = 4/ 2 = 2

radius = 2

substituting values in the volume equation

V = 3.14 x 2² x 3 /3

= 12.56

volume is 12.56 cubic units
