Answers
The above question is incomplete
Complete Question
Maurice takes a roast out of the oven when the internal temperature of the roast is 165°F. After 10 minutes, the temperature of the roast drops to 145°F.
The temperature of the room is 72°F.
How long does it take for the temperature of the roast to drop to 120°F?
Answer:
27.3143 minutes
Step-by-step explanation:
Using the Newton's law of cooling: The formula is given as:
T (t) = T₀ + T₁ e^ (rt)
Where
T₀ = Original temperature of the room (°F) ; 72°F
T₁ = Temperature of the roast (°F)
This is calculated as:
165 - 72 =93°F
r = Rate of cooling (°F/min)
t = time (min)
Substituting the values, we can obtain:
T (t) = 72 + 93 e ^rt
Step 1
We solve for r
From the question, we know that: the temperature dropped to 145°F after 10 minutes,
t =10 mins and T(10) = 145 °F
Substituting
T(10) = 72 +93 e^10r
145 = 72 + 93 e^10r
145 - 72 = 93 e^10r
Divide both sides by 93
(145-72)/93 = e^(10r)
We take the natural logarithm of both the left and right hand sides
In [(145-72)/93 ] = In (e^10r)
In [(145-72)/93 ] = 10r
-0.24214 =10r
r = -0.24214/10
r = -0.02421 °F/min
Substituting into
-0.02421 °F/min for r in the Equation below
T (t) = 72 + 93 e ^rt
T (t) = 72 + 93 e^ (-0.024214t)
To find the time taken to reach 120°F, we substitute into equation
120 = 72 +93 e^(-0.024214 ×t)
(120-72)= 93 e^ (-0.024214t)
Divide bother sides by 93
[(120-72)/93] = e^-0.024214t
We take the natural logarithm of both sides
In[(120-72)/93] = In(e^-0.024214t)
-0.66139 = -0.024214t
Divide both sides by -0.024214t
t = -0.66139/ -0.024214
t =27.3143 minutes

A baseball team has a 20-person roster. A batting order has nine people. How many different batting orders are there
Answers
Answer:
60,949,324,800
Step-by-step explanation:
We solve the above question using Permutation formula
The formula for Permutation =
nPr = n!/(n - r)!
Total Amount in a Set (n) = 20 persons
Amount in each Sub-Set (r) = 9 batting order
Hence:
20P9 = 20!/(20 - 9)!
= 60,949,324,800
Therefore, the different batting orders they would have are: 60,949,324,800

D.
We cannot say which is larger or
smaller than the other.
Answers
Answer:
The fraction with the smaller denominator is the larger fraction.
Step-by-step explanation:
Let's take [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{10}[/tex]. The larger the denominator, the more the number of pieces. So if you have a pizza box divided into 6 slices, and they are all the same size, compared to that same box of pizza divided into 10 slices. Each of those 10 slices will be smaller than the 6 slices. Now if you eat 5 of the 6 slices, compared to if you eat 5 of the 10 slices, which one will make you more full and you know that you have eaten a lot? Of course, it is the 5 out of 6 slices because each of those slices is bigger. So the smaller the denominator of the fraction, the larger it is (if the numerator stays the same).

The growth of a sample of bacteria can be modeled by the function bt=1001.06t where b is the number of bacteria and t is time in hours. What is the number of total bacteria after 3 hours?
Answers
Given:
The growth of a sample of bacteria can be modeled by the function
[tex]b(t)=1001.06t[/tex]
where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,
[tex]b(t)=1001.06t[/tex]
where, b is the number of bacteria and t is time in hours.
Substituting t=3, we get the number of total bacteria after 3 hours.
[tex]b(3)=1001.06(3)[/tex]
[tex]b(3)=3003.18[/tex]
Number of bacteria cannot be decimal value. So, approximate the value to the nearest whole number.
[tex]b(3)\approx 3003[/tex]
Therefore, the number of total bacteria after 3 hours is about 3003.

B) Y=x+3
C) Y=3x+1

The slope intercept form equation is y=mx+b. m is the slope and b is the y intercept. In this scenario, plug it back in to m and b. m=1 and b=3 so it would be y=1x+3. However, we don't include the one so it would just be y=x+3

What is the volume of the toy top pictured below?
Answers
Answer:
The volume of the top toy is 67.1175 cubic feet
Step-by-step explanation:
The toy top is a composite figure of a cylinder and an hemisphere, the volume of the figure is therefore, the sum of the volume of the cylinder and the hemisphere
The dimensions of the cylinder are;
The height of the cylinder = 6 feet
The diameter of the cylinder, [tex]D_{cylinder}[/tex] = 1.5 feet
Therefore, the radius of the cylinder, [tex]r_{cylinder}[/tex]= 1/2 × [tex]D_{cylinder}[/tex] = 1/2 × 1.5 ft. = 0.75 ft.
The volume of the cylinder = Area of the base × Height = π × [tex]r_{cylinder}^2[/tex] × (The height of the cylinder)
Where;
π = 3.14
∴ The volume of the cylinder = 3.14 × (0.75 ft.)² × 6 ft.= 10.5975 ft.³
The dimensions of the hemisphere are;
The diameter of the hemisphere, [tex]D_{hemispher}[/tex] = 6 feet
Therefore, the radius of the hemisphere, [tex]r_{hemisphere}[/tex]= 1/2 × [tex]D_{hemispher}[/tex] = 1/2 × 6 ft. = 3 ft.
The volume of the hemisphere = 2/3×π×[tex]r_{hemisphere}^3[/tex]
∴ The volume of the hemisphere = 2/3 × 3.14 × (3 ft.)³ = 56.52 ft.³the
The volume of the top toy = The volume of the cylinder + The volume of the hemisphere
∴ The volume of the top toy = 10.5975 ft.³ + 56.52 ft.³ = 67.1175 ft.³.

Now we need to set the equation up, it has to be 12x because the price of just one T-shirt is $12, the x is how many T-shirts are bought. The 36 is the b-intercept of the equation, and since we write this in y=mx+b, the equation is y=12x+36.
A linear model will be 12x+36.

You can actually draw both points in a graph to find out as it makes it easier to understand. Or you could think, if C has moved from (0,0) to (-2,3). It means it moves to the left of the x axis by 2, then moves up by 3 on the y axis.
So point P should move the same way. (-3, 4) move by -2 on the x axis would make it -5, and for y you go up 3 steps so 4+3=7 making P's final location (-5,7)

The equation of the line passes through (3, -2) and parallel to the given line:
[tex]y = 3x-11[/tex]The equation of the line passes through (3, -2) and perpendicular to the given line:
[tex]y=-\frac{1}{3}x-1[/tex]Step-by-step explanation:
Given the points on the graph line
(2, -1)
(1, -4)
Finding the slope between (2, -1) and (1, -4)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(1,\:-4\right)[/tex]
[tex]m=\frac{-4-\left(-1\right)}{1-2}[/tex]
[tex]m=3[/tex]
Equation of the line passes through (3, -2) and parallel to the given line.
We know that parallel lines have the same slope.
so the equation of the line parallel to the given line = 3
Thus, using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 3 and the point (3, -2)
[tex]y - (-2) = 3(x-3)[/tex]
[tex]y+2 = 3x-9[/tex]
[tex]y = 3x-9-2[/tex]
[tex]y = 3x-11[/tex]
Therefore, the equation of the line passes through (3, -2) and parallel to the given line:
[tex]y = 3x-11[/tex]
The equation of the line passes through (3, -2) and perpendicular to the given line
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 3
perpendicular slope = – 1/m = -1/3 = -1/3
Therefore, substituting the values of perpendicular slope = -1/3 and the point (3, -2) in the point-slope form of the line equation
[tex]y-\left(-2\right)=-\frac{1}{3}\left(x-3\right)[/tex]
[tex]y+2=-\frac{1}{3}\left(x-3\right)[/tex]
subtract 2 from both sides
[tex]y+2-2=-\frac{1}{3}\left(x-3\right)-2[/tex]
[tex]y=-\frac{1}{3}x-1[/tex]
Therefore, the equation of the line passes through (3, -2) and perpendicular to the given line:
[tex]y=-\frac{1}{3}x-1[/tex]
Conclusion:
The equation of the line passes through (3, -2) and parallel to the given line:
[tex]y = 3x-11[/tex]The equation of the line passes through (3, -2) and perpendicular to the given line:
[tex]y=-\frac{1}{3}x-1[/tex]Pleas help!!!
