Answer: 10.1

Step-by-step explanation:

Answer:

The possible equation is; T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]

The horizontal asymptotes is Lim(t → ∞), T → 20°C

The vertical asymptote is Lim(t → 0) T → 100°C

Step-by-step explanation:

The given parameters are;

The temperature of the house = 20°C

The initial temperature of the tea = 100°C

The temperature of the tea after 5 minutes = 70°C

From Newton's law of cooling, is given as follows;

[tex]T(t) = T_s + (T_0 - T_s) \cdot e^{k \cdot t}[/tex]

[tex]\dfrac{dT}{dt} = -k(T - T_a)[/tex]

Where;

T(t) = The temperature after time, t =

[tex]T_s[/tex] =The room temperature = 20°C

T₀ = The initial temperature of the tea = 100°C

k = Constant

T(5) = 70°C, therefore, we have;

[tex]70 = 20 + (100 - 20) \cdot e^{k \cdot 5}[/tex]

50/80 = [tex]e^{k \cdot 5}[/tex]

5·k = ㏑(5/8)

k = ㏑(5/8)/5 ≈ -0.094

Therefore, the possible equation is given as follows;

T(t) = 20 + 80·[tex]e^{(-0.094 \cdot t)}[/tex]

The asymptotes are Lim(t → ∞), T → 20°C  and Lim(t → 0) T → 100°C

The coordinate of the vertex is ( 7 ,4), the correct option is B.

An absolute value function is a function that gives positive value for a number or variable. It has a V shaped graph, it is also called as a modulus function.

The absolute function is y = | -x +7| +-4

The v shaped curve has a vertex and it can be determined by following method.

The value of the x coordinate is determined by equating the modulus to 0, the point at which the modulus is zero.

-x +7 = 0

Adding -7 to both sides.

-x = -7

x = 7

The value of y at this point is the y coordinate of the vertex.

y = 0 +4

y = 4

(x,y) = ( 7,4)

Answer:

  y = -x -1

Step-by-step explanation:

The slope of a line is the tangent of the angle it makes with the x-axis. If you want an angle of -45°, then you need a line with a slope of m = tan(-45°) = -1.

Then the y-intercept is ...

  b = y -mx

  b = 2 -(-1)(-3) = 2 -3 = -1

So, the slope-intercept equation is ...

  y = mx + b

  y = -x -1

Answer:

y = 4/3x - 3

Step-by-step explanation:

Use rise over run to find the slope, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(-7 - 1) / (-3 - 3)

-8 / -6

= 4/3

Now, plug in the slope and a point into y = mx + b to get the equation:

y = mx + b

1 = 4/3(3) + b

1 = 4 + b

-3 = b

Plug in the slope and y intercept into the equation:

y = 4/3x - 3

So, the equation is y = 4/3x - 3

Answer:50%

Step-by-step explanation:

Steve's expected times of winning in 12 trials is about 2 times.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

The winning chance of Steve is 20% or 0.2.

We know, We know The expected value, also known as the expectation, average, is a generalization of the weighted average in the field of probability theory.

Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen.

Therefore, If he plays the game 12 times the number of times he is expected to win is,

= 12×0.2.

= 2.4 Or 2 times.

This is a division problem.

You need to divide 24 by 1/2.

24 / 1/2 = 24/1 / 1/2 = 24/1 * 2/1 = 48/1 = 48

Answer: 48

You can also do it this way.

Each acre is the same size as 2 half-acres.

1 acre = 2 half-acres

Multiply both sides of the equation above by 24.

24 * 1 acre = 24 * 2 half-acres

24 acres = 48 half acres
