Step-by-step explanation:

Answer:

The slope is -1.333.

Step-by-step explanation:

Answer:

The equation is;

y = 200•0.8^x

where y is the number of bears remaining and x is the year number in particular

Step-by-step explanation:

Let us have the rate of decrease as r and we set up an exponential equation

y = I• ( 1 - r)^x

where r is the percentage decrease, I is the initial population = 200 and x is the number of years

For the population after 1 year, we have;

160 = 200( 1 -r)^x

divide both sides by 200

0.8 = (1-r)^1

0.8 = 1 - r

r = 1 - 0.8

r = 0.2

So the equation will be;

y = 200( 1 - 0.2)^x

y = 200•0.8^x

Step-by-step explanation:

Answer:

The liquid will take 17.5 minutes to reach -10.5 ºC.

Step-by-step explanation:

From this statement we understand that the temperature of liquid is increased at constant rate in time, whose model is described by:

[tex]T (t) = \dot r \cdot t + T_{o}[/tex] (Eq. 1)

Where:

[tex]T[/tex] - Temperature of the liquid, measured in degrees Celsius.

[tex]\dot r[/tex] - Heating rate, measured in degrees Celsius per minute.

[tex]t[/tex] - Time, measured in minutes.

[tex]T_{o}[/tex] - Initial temperature, measured in degrees Celsius.

If we know that  [tex]\dot r = -0.60\,\frac{^{\circ}C}{min}[/tex] and [tex]T_{o} = 0\,^{\circ}C[/tex], the temperature model for the liquid is:

[tex]T(t) = -0.60\cdot t[/tex] (Eq. 2)

In addition, if [tex]T(t) = -10.5\,^{\circ}C[/tex], then time taken for the liquid to reach that temperature is:

[tex]t = \frac{-10.5}{-0.60}[/tex]

[tex]t = 17.5\,min[/tex]

The liquid will take 17.5 minutes to reach -10.5 ºC.

a = 63

==============================================

Explanation:

For now, focus on triangle COA.

Since OC and OA are the two radii, this means OC = OA. Furthermore, it means triangle COA is isosceles.

Any isosceles triangle has its base angles congruent to one another. In this case, the base angles are A and C. Both are equal to lowercase 'a'.

So now we know that triangle COA has angles A = a, C = a, O = 54. The three angles of any triangle add to 180

C+O+A = 180

a+54+a = 180

2a+54 = 180

2a = 180-54

2a = 126

a = 126/2

a = 63

---------------------------

Now turn your attention to triangle ABC. This is a right triangle (due to Thales Theorem). The right angle is at angle C, so C = 90.

Use the same idea as before to find b

A+B+C = 180

a+b+90 = 180

63+b+90 = 180

b+153 = 180

b = 180-153

b = 27

x=36

Answer:

V would be equivalent to 300 students

Step-by-step explanation:

Noting that 3 teachers already have 60 students

If we're given 15 teachers, try dividing it by the 3 teachers that we originally have.

15/3 would be 5

We would now proceed to multiply the 60 students by 5 for the total amount of students with 15 teachers.

60*5 would be 300

Your answer should be 300 students.

2/3 - 1/4 = 5/12

Simplify the following:

2/3 - 1/4

Hint: | Put the fractions in 2/3 - 1/4 over a common denominator.

Put 2/3 - 1/4 over the common denominator 12. 2/3 - 1/4 = (4×2)/12 - 3/12:

(4×2)/12 - 3/12

Hint: | Multiply 4 and 2 together.

4×2 = 8:

8/12 - 3/12

Hint: | Subtract the fractions over a common denominator to a single fraction.

8/12 - 3/12 = (8 - 3)/12:

(8 - 3)/12

Hint: | Subtract 3 from 8.

8 - 3 = 5:

Answer: 5/12

Convert 5/12 to decimal = 0.4166666666666666666666666666666666666666666666666666666666666666

The slope tells us that the cost increases as the number of ordered hats increases.

Given,

A little league baseball team is ordering hats.

The graph shows the relationship between the total cost, in dollars, and the number of hats ordered.

We need to find out what the slope of the graph tells us in this situation.

The slope in a graph tells us the relationships between the data on the x-axis and the y-axis.

The points on the slope give the relationships between the particular point on the x-axis and the y-axis.

The slope tells us the rate of change of y relative to x.

We see that,

If the number of orders of hats is 1, the total cost is $50.

1 order = $50

Similarly,

2 order = $60

3 order = $80

4 order = $90

5 order = $100

6 order = $120

7 order = $130

8 order = $150

9 order = $160

10 order = $170

11 order = $190

We see that as the order of hats increases the cost also increases.

Thus the slope tells us that the cost increases as the number of ordered hats increases.
