The circumference of a circular rug is 24.8 meters. What is the area of the rug? Use 3.1 for pi
mestny [16]

Answer:

The area of rug is 48.9 m^2

Step-by-step explanation:

Let's assume radius of rug is r m

we know formula for circumference as

C=2\pi r

we are given

C=24.8

and then we can solve for r

24.8=2\pi r

r=3.947

now, we can use area formula

A=\pi r^2

we can plug r

and we get

A=\pi (3.947)^2

A=48.94227

So,

The area of rug is 48.9 m^2

The function f is defined by f(x) = a + bcos2x, for 0 ≤ x ≤ π. It is given that f(0)=−1 and f(1/2π) = 7. (i) Find the values of
olga_2 [115]
Sub in given values to get 2 equations.

a + b \cos(2*0) = -1 \rightarrow a+b = -1 \\  \\ a+b \cos(2*\frac{\pi}{2}) = 7 \rightarrow a - b = 7

Solve system using elimination.  Add the equations together, cancelling out 'b'
2a = 6 \\  \\ a = 3

Sub into first equation to get value for 'b'
3+b = -1 \\  \\ b = -4

Given x and y are integers, explain why the product of the expression and it's conjunct will always be an integer
mars1129 [50]

Answer:

If neither of the two real numbers is zero, then their product is also not zero Suppose also that x is a real number that satisfies the equation The " / " symbol does not always give you a result of an integer, so be careful.pkek, and any other expression for n as a product of prime numbers is identical to this except,.

Subtract -7n +2 from 2n - 1
Irina18 [472]
2n - 1    -      -7n + 2     You combine like terms with subtracting
2n - 7n = -5n
-1 - 2 = -3
So -7n + 2     -     2n - 1 = -5n - 3
