The field inside a running track is made up of a rectangle that is 84.39 m long and 73 m wide, together with a half-circle at ea

ioda

Answer:

The distance around the inside is 199.44 m.

Step-by-step explanation:

Given that,

Length = 84.39 m

Width = 9.76 m

Suppose, all the way around and 73 m wide.

We know that,

Perimeter of half circle is

$perimeter = \pi r$

We need to calculate the inner radius of the circle

Using formula of radius

$r=\dfrac{D}{2}$

Put the value into the formula

$r=\dfrac{9.76}{2}$

$r=4.88\ m$

We need to calculate the distance around the inside

Using formula of distance

Distance around the inside= two inner perimeter of the circle+two length of rectangle

$D=2\pi r+2l$

Put the value into the formula

$D=2\pi\times4.88+2\times84.39$

$D=199.44\ m$

Hence, The distance around the inside is 199.44 m.

Let P(x) be the statement"x= x2", If the domain consists of the integers, what are these truth values? (a) P(0) (b) P(1) (c) P(2

jeka57 [31]

Answer: i guess the problem is with P(x) => "x = $x^{2}$ ", then P(x) is true if that equality is true, and is false if the equality is false.

so lets see case for case.

a) x = 0, and $0^{2}$ = 0. So p(0) is true.

b) x = 1 and $1^{2}$ = 1, so P(1) is true.

c) x = 2, and $2^{2}$ = 4, and 2 ≠ 4, then P(2) is false.

d) x= -1 and $1^{2}$ = 1, and 1 ≠ -1, so P(-1) is false.
