<h2>Answer:</h2>
√44
2 Real Roots
<h2>Step-by-step explanation:</h2>Looking at the image attached, the discriminant is the value under the square root.
In the equation given:
a = 1
b = -8
c = 5
The discriminant is therefore:
√(b²- 4ac) = √(-8²- (4*1*5)) = √(64-20) = √44
√44 is a positive number. Because it is positive, there must be 2 real roots.
If it were negative, there would be 2 imaginary roots.
If it were zero, there would be 1 real root.
Answer:
WZ = 51 mm.
Step-by-step explanation:
The trapezoid figure STUV is a scaled version of figure WXYZ.
The figure STUV to figure WXYZ has a scale factor of 3 : 1.
So, the corresponding lengths of the two figures will be in the 3 : 1 ratio.
Then,
So, SV = 3 × WZ
⇒ 153 = 3 × WZ
⇒ WZ = 51 mm (Answer)
