Answer:

-124

Step-by-step explanation:

The equation for a discriminant is:

$b^{2} -4ac$

So for

$7x^{2} -4x +5=0$

a = 7 b = - 4 c = 5

Plug values into the equation.

$(-4)^{2} -4(7)(5)$

16 - 140 = -124

Calculate the area of the shaded sector in the circle

scZoUnD [109]

Answer:

area ≈ 6.3 units²

Step-by-step explanation:

Calculate the area (A ) of the sector as

A = area of circle × fraction of circle

= πr² × $\frac{45}{360}$

= π × 4² × $\frac{1}{8}$

= 16π × $\frac{1}{8}$ ← cancel 8 and 16 by 8, leaving

A = 2π ≈ 6.3 units² ( to 1 dec. place )
