Answer:

The value of the given function f(x) at x = 0 is 0

Step-by-step explanation:

The function is given to be :

f(x)=\tan^{-1}x

Now, we need to find the value of the given function f(x) when x = 0

So, To find f(0) we substitute x = 0 in the given function f(x)

\implies f(x)=\tan^{-1}x\\\\\implies f(0)=\tan^{-1}(0)\\\\\implies f(0)=\tan^{-1}(\tan 0)\\\\\implies f(0)=\tan^{-1}\tan(0)\\\\\implies f(0)=0

Therefore, The value of the given function f(x) at x = 0 is 0

Need help plsss give you brainliest plssss help me it’s rounding money cents, dime and dollar
Vladimir [108]

Answer:

Please see the attached image for solution.

Step-by-step explanation:

Cent:  Rounding to the nearest cent or multiple of 0.01.

Dime: Rounding to the nearest 10 cents or multiple of 0.10.

Dollar: Rounding to the nearest dollar or multiples of 1.

For example, in question #21:

To round $12.3456 to the nearest cent:  you must look at the hundredths place, and pay attention to the digit to its right. In this case, the digit at the hundredths place is 4, and to its right is 5. Therefore, you must round it up to 5, making it $12.3<u>5</u>.

To round $12.3456 to the nearest dime:  you must look at the tenths place, and pay attention to the digit to its right. In this case, the digit at the tenths place is 3, and to its right is 4. Since 4 is less than 5, you must round 4 down to 0, making it into $12.<u>3</u>0.

To round $12.3456 to the nearest dollar:  you must look at the ones place, and pay attention to the digit to its right. In this case, the digit at the ones place is 2, and to its right is 3. Since 3 is less than 5, you must round 3 down to 0, making it into $1<u>2</u>.00.

How many more calories do you burn per minute downhill skiing than hiking
FrozenT [24]

Answer: 2 more calories skiing

Step-by-step explanation:

First find the slope of each line.

Slope of Skiing:

= (Y₂ - Y₁) / (X₂ - X₁)

= (400 - 240) / (50 - 30)

= 8

= 8 calories per minute

Slope of Hiking

= (360 - 120) / (60 - 20)

= 6

= 6 calories per minute

Difference:

= 8 - 6

= 2 more calories skiing

What is the solution to x=1/2y-3 and y=2x+6
Tom [10]

Answer:

infinite solutions

Step-by-step explanation:

Multiply the first equation by 2 so we don't have fractions.

x = 1/2y - 3 becomes 2x = y - 6

Now substitute the second equation into the y-value of the new equation

2x = (2x + 6) - 6

2x = 2x

x can equal anything. this means there are infinite solutions
