Answer:

A) The equation for circumference is C=2piR. So Filling in for circle A we have 28.26=2*pi*4.5 so we want to isolate pi which I'm gonna call x for it's easier for me xD. So we're gonna start by dividing 4.5 from each side which is gonna leave us with 6.28=2*x which gives you x(pi)= 3.14. For circle B we have 15.70=2*x*2.5 isolate x by first dividing 2.5 which leaves us again with 6.28=2x and x= 3.14.

B) The equation for area is A=piR^2. So again for circle A we have 63.585=x9^2. This one is harder but also are you sure that the area is 63.585 it's supposed to be 254.469 (We'll come back to this)

C) The observation you can make about the value of pi for circles A and B is that it stays consistent at 3.14

hoped i helped : )

A) No solutions, because the number under the square root symbol in the quadratic equation (b^2 - 4ac) is negative.

B) One solutions, because the number under the square root symbol in the quadratic equation (b^2 - 4ac) is equal to 0.

Find the factors of f(x) given that x = 5 is a zero.

77julia77 [94]

If x = 5 is a zero of the given polynomial, then,
(x - 5) is a factor of the polynomial. [Since, x = 5 or, x - 5 = 0]
Now, divide the polynomial with (x - 5) using long division method. (See the picture)
We get (x^2 - x - 6) as the quotient.
Now, factorise the above polynomial:
(x^2 - x - 6)
= (x^2 - 3x + 2x - 6)
= x(x - 3) + 2(x - 3)
= (x - 3)(x + 2)
Therefore, x^3 − 6x^2 − x + 30 = (x − 5)(x − 3)(x + 2)

Answer:

B.(x − 5)(x − 3)(x + 2)

Hope you could get an idea from here.

What is the value of x?

Westkost [7]

Answer:

x is equal to 20 in this picture.

Step-by-step explanation:

In order to find this, we need to note that these two angles will be equal to each other. Now we can put their values equal to each other and solve for x.

3x + 50 = 6x - 10

50 = 3x - 10

60 = 3x

20 = x
