According to the question,

Time taken by Jesse to run 1 mile = 7 minutes

Also,

Time taken by Jesse to run 1 mile = 2½ minutes + Michael's time [tex]\;[/tex]

Now, we can say that :

⇒ 7 minutes = 2½ minutes + Michael's time

⇒ (7 - 2½) minutes = Michael's time

⇒ (7 - 5/2) minutes = Michael's time

⇒ (14 - 5)/2 minutes = Michael's time

⇒ 9/2 minutes = Michael's time

⇒ 4½ minutes = Michael's time [Answer]

Step-by-step explanation:

Question:-In track practice, Jesse ran a mile in 7 minutes. His mile time was2.5 minutes faster than Michael's time. Write and solve an equation to calculate Michael's mile time.

Solution

Jessie time 7 minute

Michael’s time is 2.5 times slower

Divide 7 minutes by 2.5 to get answer

Jesse = 7

Michael = 2.5 X

7 = 2.5 X

7/2.5 X = 17.5 to check answer divide 17.5 by the 2.5, your answer is 7.

Or if it was 2.5 more

we subtract 2.5 from 7

=> 7 - 2.5

=> 4.5

=> 4 ½

Step-by-step explanation:

easy

A) The equation for the growth of bacteria over time is : n(t) = 27(   [tex]e^{25t}[/tex])

B) The number of bacteria the would be in 5 minutes 1 hour is :

n(5mins) = 215.055 ,  n(1) = 1944132282109.422

C) The time it will take for the bacteria to reach a population of 10,000 is : t = 0.237 hours

Applying the mathematical growth and decay modelling

a. n(t) = [tex]n_{0}[/tex] [tex]e^{rt}[/tex]

[tex]n_{0}[/tex] = initial amount of bacterial

[tex]e^{rt}[/tex] = exponent

r = rate

t = time

n(t) = 27(   [tex]e^{25t}[/tex])

b. for 5 minutes

converting 5 minutes to hours; we divide by 60 minutes

[tex]\frac{5}{60}[/tex] = 0.083 hour

n(5 mins) = 27(   [tex]e^{25t}[/tex])

n(5 mins) = 27(   [tex]e^{25 * 0.083}[/tex])

n(5 mins) = 27(   [tex]e^{2.075}[/tex])

n(5mins) = 27(   7.965)

n(5mins) = 215.055

For 1 hour we have

n(1) = 27(   [tex]e^{25t}[/tex])

n(1) = 27(   [tex]e^{25 * 1}[/tex])

n(1) = 27(   [tex]e^{25}[/tex])

n(1) = 27 * (72004899337.386)

n(1) = 1944132282109.422

c. How long will it take for the bacteria to reach a population of 10,000?

10000 = 27(   [tex]e^{25t}[/tex])

[tex]\frac{10000}{27}[/tex] = (   [tex]e^{25t}[/tex])

370.370 = (   [tex]e^{25t}[/tex])

㏑ (370.370 ) = ㏑ (   [tex]e^{25t}[/tex])

5.915 = 25t

[tex]\frac{5.915}{25}[/tex] = t

t = 0.237 hours

In conclusion this type of question can be done by mathematical modelling

Answer:

Slope of the line DV = -1

Step-by-step explanation:

Let point D (-5, 1) be [tex](x_{1}, y_{1})[/tex]

Let point V (-1, -3) be [tex](x_{2}, y_{2})[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Plug in the appropriate values,

[tex]m = \frac{-3-1}{-1-(-5)} = \frac{-4}{4} = -1[/tex]

slope equals -1

From the computation below, the area of the label is 707 Inches.

This calculation is carried out using the theorem of the area of curved shapes.

The formula for the Curved Surface Area of a Cylinder is given as:

                                               2 [tex]\pi[/tex] rh

                                              =  2 [tex]\pi[/tex] x 7.5 x 15.

This assumes that the label also ends at an equal distance from the top of the lid.  Hence 15in = 20 - (2.5 x2);

Recall that [tex]\pi[/tex] =  22/7, hence

= 2 x (22/7) x  7.5 x 15

= 707.142857143

Approximately, this equals; 707 Inches.

Hence, the area of the label = 707 inches.

Notice that the question is incomplete. From inference, however, the general calculation above contains the principles for calculating the area of a label.

A function assigns values. The difference between the maximum value of g(x) and the minimum value of f(x) is 18.

A function assigns the value of each element of one set to the other specific element of another set.

Since the maximum of the parabola function g(x) will lie at its vertex, therefore, the maximum will be at (3,12). Now, if we try to find the minimum of the function f(x). We need to plot the function on the graph as shown below.

As the minimum of the function f(x) will lie at the vertex of the parabola function, therefore the minimum of the function f(x) will lie at (3,-6).

If we try to find the difference between the maximum value of g(x) and the minimum value of f(x), then we will get,

[tex]\rm Difference=12-(-6)=18[/tex]

Thus, the difference between the maximum value of g(x) and the minimum value of f(x) is 18.

The general form of the equation of a circle is

(x-a)^2 + (y-b)^2 = r^2   where the center is (a,b)

Plugging in the given values:-

(6 - a)^2 + (4-b)^2 = r^2    and

(6-a)^2 + (2-b)^2  = r^2

Subtracting:-

(4-b)^2 - (2 - b)^2  = 0

16 - 8b + b^ - (4 -4b + b^2) = 0

12 - 4b  = 0

-4b =  -12

b = 3

Similarly if we take the 2 points (6,2) and G(10,2)  and make two equations we can find the value of a

(6-a)^2 + (2-b)^2  = r^2

(10.a)^2 + (2-b)^2 = r^2    subtract::-

(6-a)^2 -(10-a(^2 = 0

this will give a = 8

Slip system can be used to give more than fair chances of selection where the number of slips for one is more than the other.

There are multiple ways of selecting random sample like tossing a coin, flipping a die, lottery system.

Describing a method which can be used to provide more than a fair chance of selection is as follows:

Julie has 3 friends, so make the total number of slips say n

where n is not a multiple of 3.  

If n is not a multiple of 3 then her 3 friends will not get an equal chance of being selected.

Consider n=5

She has 3 friends, so 2 slips has repeated names, thus creating more chance of being selected than the one who has name only on one slip.

Thus, this method may result in more chance of selection of one over other.
