Answer: The correct answer is 8 meters

Step-by-step explanation:

Circumference=2pi*r or

and diameter=2r

in your case, the circumference is 25.12 miles, so we plug it in to the first formula:

25.12=2pi*r

12.56=3.14*r

4=r

and since 2r=diameter, the diameter is 8

* Hopefully this helps:) Mark me the brainliest:)!!

Find the domain of - y/(y-6) +15/(y+6) - y-10/y^2+3

ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

Domain of a function represents the set of x-values (input values) and y-values (output values) of the function represent the Range of the function.

Given function is,

If Domain (input values) of this function is,

{-12, -6, 3, 15}

Table for the input-output values of this function,

x -6 3 15 -12

y 11 5 -3 15

Use the definition of continuity and the properties of limits to show that the function

Zepler [3.9K]

Answer:

Applied the definition and the limit.

They had the same result, so the function is continuous.

Step-by-step explanation:

At function f(x) is continuous at x = a if:

$\lim_{x \to a} f(x) = f(a)$

In this question:

$f(x) = x^{2} + 5(x-2)^{7}$

At x = 3.

$\lim_{x \to 3} x^{2} + 5(x-2)^{7} = 3^{2} + 5(3-2)^{7} = 14$

$f(3) = 3^{2} + 5(3-2)^{7} = 14$

Since $\lim_{x \to 3} f(x) = f(3)$ , f(x) is continuous at x = 3.

Allen started his homework at 8:10 p.M. And worked for 45 minutes. Then he phoned a friend and talked for 20 minutes He went to

Luba_88 [7]

Answer:

Allen go to bed at 9:15 p.m.

Step-by-step explanation:

Given:

Allen started his homework at 8:10 p.M. And worked for 45 minutes. Then he phoned a friend and talked for 20 minutes. He went to bed when he finished the call.

Now, to find the time Allen go to bed.

Allen started his homework at 8:10 p.m.

And worked for 45 minutes.

So, to get the time when he finished homework is by adding 45 minutes and the time when he started homework:

$8.10+45$

$=8.55\ p.m.$

Thus, he finished his homework at 8:55 p.m.

Then he phoned a friend and talked for 20 minutes and went to bed when he finished the call.

As, 1 hour = 60 minutes.

Now, to get the time when he go to bed by adding 20 minutes and the time when he finished homework:

$8.55+20=9.15\ p.m.$

Therefore, Allen go to bed at 9:15 p.m.
