Answer:
The circle's diameter is 6cm
Step-by-step explanation:
A = 28.26 cm^2
D = ![\sqrt[2]{\frac{A}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%20%7D%20%7D)
D = ![\sqrt[2]{\frac{28.26}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7B28.26%7D%7B%5Cpi%20%7D%20%7D)
D = 6cm
Answer:
y = x² - 3x - 28
Step-by-step explanation:
given a parabola with x- intercepts x = a and x = b , then
(x - a) and (x - b) are the corresponding factors and the equation is the product of its factors
y = (x - a)(x - b)
here the x- intercepts are x = - 4 and x = 7 , then the factors are
(x - (- 4)) and (x - 7) , that is (x + 4) and (x - 7) , then
y = (x + 4)(x - 7) ← expand using FOIL , then
y = x² - 3x - 28 ← in standard form
For some reason, you're not letting us see the choices,
so I can only give you a most general answer:
-- Any positive fraction greater than 1/2 is closer to 1 than it is to 0 .
-- No negative fraction is.
The answer is 15x-5
Hope this helps
