Anderson could provide 0.5x2 + 4x + 8 = 0 has exactly one real root if the discriminant is 0,

<h3>What is quadratic equation?</h3>

Any equation that can be rewritten in standard form as where x represents an unknown, a, b, and c represent known numbers, and where a 0 is true is a quadratic equation. As there is no ax2 term when a = 0, the equation is linear rather than quadratic.

<h3>What is discriminant?</h3>

A polynomial's discriminant is a quantity that depends on the coefficients and enables for some root attributes to be inferred without actually computing them. It is actually a polynomial function of the original polynomial's coefficients.

<h3>According to the given information:</h3>

0.5x^2 + 4x + 8 = 0

The discriminant is computed utilizing:

d = b^2 - 4ac

Thus, we have:

d = 4^2 - 4 * 0.5 * 8

Evaluate

d = 0

The equation has only one real root since the discriminant is 0,

Decimal places mean we just start counting immediately after the decimal point, so:
2dp: 0.00
1dp: 0.0

Significant figures, we start counting starting at the first non zero number
So we start counting at the 9, therefore:
2sf: 0.00097
3sf: 0.000965

Urgent! <br> Find the area created by the overlapping circles given the following information.
Stels [109]

Answer:

209.55in²

Step-by-step explanation:

Find area of sector CADE

Radius =22 in

Angle=90°

Formula to apply is ;

Ф/360 × π × r² where

Ф=angle of sector, π=3.142 and r =radius of circle

A=\frac{90}{360} *3.142*22*22=380.182in^2

Find area of triangle CAD where base length is 22 inches and height is 22 inches

Area of triangle formula is;

1/2×b×h where b is base and h is height

A=\frac{1}{2} *22*22=242in^2

Find area remaining

380.182-242=138.182in²

Find the area of sector CBDF

Radius=28in

Angle=60°

Formula to apply is ;

Ф/360 × π × r² where

Ф=angle of sector, π=3.142 and r =radius of circle

A=\frac{60}{360} *3.142*28*28=410.55in^2

Area of triangle BDC

The formula to apply is

1/2×a×a×sinФ where a=28 inches and Ф=60°

\frac{1}{2} *28*28*sin60=339.48in^2

Remaining area

410.55-339.48=71.075in²

Area created by overlapping circles

138.182+71.075=209.26in²
