If a cup of coffee has temperature 97°C in a room where the ambient air temperature is 25°C, then, according to Newton's Law o
FinnZ [79.3K]

Answer:

The  average temperature  is T_{a} = 81.95^oC

Step-by-step explanation:

From the question we are told that

    The temperature of the coffee after time t is   T(t) =  25 + 72 e^{[-\frac{t}{45} ]}

Now the average temperature during the first 22 minutes i.e fro 0 \to  22minutes is mathematically evaluated as

              T_{a} =  \frac{1}{22-0}  \int\limits^{22}_{0} {25 +72 e^{[-\frac{t}{45} ]}} \, dx

               T_{a} = \frac{1}{22} [25 t  +  72 [\frac{e^{[-\frac{t}{45} ]}}{-\frac{1}{45} } ] ] \left| 22} \atop {0}} \right.

             T_{a} = \frac{1}{22} [25 t  - 3240e^{[-\frac{t}{45} ]} ] \left | 45} \atop {{0}} \right.

              T_{a} = \frac{1}{22} [25 (22)  - 3240e^{[-\frac{22}{45} ]}   - (- 3240e^{0} )]

            T_{a} = \frac{1}{22} [550  - 1987.12  +  3240]

          T_{a} = 81.95^oC

The legs of a right triangle are 10 centimeters and 24 centimeters long. What is the length of the hypotenuse?
Rina8888 [55]
A² + b² = c²

Where a and b are the legs and c is the hypotenuse

So, plug in 10 for one of the legs and 24 for the other leg

c will be left blank because that is what you are trying to find, the hypotenuse

10² + 24² = c²

100 + 576 = c²

676 = c²

Take the square root of both sides of the equation to isolate c

√676 = √c²

Square of c and the square root cross out on the right

Take the square root of 676

c = 26

So, the length of the hypotenuse is 26 centimeters

Which of the following functions is not a linear
kicyunya [14]

By looking at the degree of the polynomials, we conclude that the option that is not linear is option C.

<h3>Which of the following functions is not a linear function?</h3>

A polynomial is an expression of the form:

p(x) = a_n*x^n + a_{n-1}*x^{n-1} + ... + a_0

Where all the exponents are natural numbers.

We define the degree of a polynomial as the largest exponent, and we define a linear function as a polynomial of degree 1.

So a linear function is of the form:

f(x) = a_1*x + a_0

Now, if you look at option C, you can see that the degree of that polynomial is 2. So that is not a linear function.

Then the correct option is C.
