Answer:

5 shaded region area = 100 - 78.5 = 21.5 sqm

6 c

Step-by-step explanation:

5. area of square = 10 x 10 = 100 sqm

area of circle = pi * r^2 = pi (5)^2 = 78.5 sqm (take pi as 3.14)

shaded region area = 100 - 78.5 = 21.5 sqm

6. for a straight line, equation is y = mx + b

m = 5, b = -12 in this case

Order the group of parabolas from widest to narrowest.

Mamont248 [21]

Answer:

$\large\boxed{y=\dfrac{1}{4}x^2,\ y=-\dfrac{1}{2}x^2,\ y=\dfrac{3}{2}x^2}$

Step-by-step explanation:

The equation of a parabola: y = ax²

The larger the value of |a|, the narrower the parabola.

We have the following coefficients a:

$\left|\dfrac{1}{4}\right|=\dfrac{1}{4},\ \left|-\dfrac{1}{2}\right|=\dfrac{1}{2},\ \left|\dfrac{3}{2}\right|=\dfrac{3}{2},$

We arrange the coefficients from the smallest to the largest:

$\dfrac{1}{4}\$

Therefore you have the answer:

$y=\dfrac{1}{4}x^2,\ y=-\dfrac{1}{2}x^2,\ y=\dfrac{3}{2}x^2$
