First you find the circumference... 2pi*r... and then you multiply that by 2.125. To find out the total amount of meters that the man walks!

We are given radius of circle as 4m.

Now if a man walks around a circle means we are considering the circumference here.

Circumference of circle can be found with the formula:

Circumference = 2* \pi *r

Where r = radius of circle and pi = 3.14

plugging these values in the formula ,

Circumference = 2* 3.14 *4

Circumference = 25.12 m

Now distance covered by man when he walks around the circle once = 25.12m

distance covered by man when he walks around the circle 2.125 times = 25.12 *2.125 = 53.38 m

Answer : 53.38 m

The value of the functions f(x) and g(x) will be √(4x + 3) and √2. Then the correct option is B.

<h3>What is a function?</h3>

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

If (f g)(x) = h(x) such that h(x) = √(8x + 6). Then we have

(f g)(x) = h(x)

f(x) · g(x) = h(x)

Then put the value of h(x), then we have

f(x) · g(x) = √(8x + 6)

f(x) · g(x) = √2(4x + 3)

f(x) · g(x) = √(4x + 3) × √2

Thus, the value of the functions f(x) and g(x) will be √(4x + 3) and √2.

Then the correct option is B.

Monica [59]

Answer:

First of all you spelled years instead of yards. But I'd say that Mallory has the longer piece of wire.

Step-by-step explanation:

Because of 2.16 yds over 1 times 1 meter over 3 yds. You divide them instead of multiplying, you get 1.97 meters.
