The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is 0 \le t \le 165

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

The range is 0 \le H \le 40000 since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.

The sum of three consecutive even numbers is 48. What is the smallest of these numbers?
SVETLANKA909090 [29]

Answer: The numbers are 14, 16 and 18.

Step-by-step explanation: First thing to note is that consecutive even numbers have a difference of 2 units between every two terms. That is, if the first number is a, the next would be a + 2, and the next would be a + 4, and so on.

Therefore the three consecutive even numbers shall be a, a + 2, and a + 4.

Our equation now becomes;

a + a + 2 + a + 4 = 48

3a + 6 = 48

Subtract 6 from both sides of the equation

3a = 42

Divide both sides of the equation by 3

a = 14

Therefore, the numbers are 14, 16 and 18.

If f(x)=2−x12 and g(x)=x2−9, what is the domain of g(x)÷f(x)?
Keith_Richards [23]
\bf \begin{cases}
f(x)=2-x^{12}\\
g(x)=x^2-9\\
g(x)\div f(x)=\frac{g(x)}{f(x)}
\end{cases}\implies \cfrac{x^2-9}{2-x^{12}}

now, for a rational expression, the domain, or "values that x can safely take", applies to the denominator NOT becoming 0, because if the denominator is 0, then the rational turns to undefined.

now, what value of "x" makes this denominator turn to 0, let's check by setting it to 0 then.

\bf 2-x^{12}=0\implies 2=x^{12}\implies \pm\sqrt[12]{2}=x\\\\
-------------------------------\\\\
\cfrac{x^2-9}{2-x^{12}}\qquad \boxed{x=\pm \sqrt[12]{2}}\qquad \cfrac{x^2-9}{2-(\pm\sqrt[12]{2})^{12}}\implies \cfrac{x^2-9}{2-\boxed{2}}\implies \stackrel{und efined}{\cfrac{x^2-9}{0}}

so, the domain is all real numbers EXCEPT that one.

The square root of 3 multiplied by the cube root of 2
Nutka1998 [239]

Answer:

2.18224727194 is what I got

Step-by-step explanation:

The square root of 3 is 1.73205080757 and you just multiply that by 1.25992104989(which is the cube root of 2) and then you get the answer of 2.18224727194

john can shovel a certain driveway in 50 minutes if mar can shovel the same driveyway in 20 minutes how long will it take them t
Assoli18 [71]

John and Mar need 14 minutes complete shovel their driveway together, to the nearest minute.

<h3>What is rate of doing work?</h3>

You can use this computation to determine the hourly value of each employee's job, allowing you to more effectively and efficiently plan your staffing needs in the future.

This is crucial because it enables you to determine the ideal workforce size based on your average hourly wage.

According to the question;

by calculating the fraction of unit work that each individual can finish in a given amount of time together work is estimated.

Mary can clear 1/20 of a driveway in a minute, but John can clear 1/50 of it in that time.

The both will do the same job in;

= (1/20) + (1/50)

= (5/100) + (2/100)

= 7/100

They'll be finished when they've cleared 100 percent of the driveway, therefore the equation we must finally solve is:

7x = 100.

x = 100/7

x = 14.28

Therefore, when John and Mar will work together, they will shovel the driveway in 14 minutes (to the nearest minute).
