Finding the roots (zeros)

Mathematics
1 answer:
GenaCL600 [577]2 years ago
4 0

Answer:

1.5 + 1.3228756555323i

1.5 - 1.3228756555323i

Step-by-step explanation:

y = ax^2 + bx + c

a = 1, b = -3, c = 4

Using the quadractic formula:

\frac{-b±\sqrt{b^2-4ac} }{2a} \\\\= \frac{3±\sqrt{9-4(1)(4)}}{2(1)}\\\\= \frac{3±2.64i}{2}\\\\= 1.5 ±  1.32

Note: Kindly ignore the A in the above solution ^

Hence, there is no real solution. It has complex roots.

What is the volume of the composite figure? Express the answer in terms of π.
topjm [15]

Answer:

312π mm³

Step-by-step explanation:

Given:

Oblique cone height, h = 14 mm

radius of half sphere = base radius of cone, r = 6 mm

Recall the volume of 1/2 - sphere

= 1/2 x volume of sphere

=  1/2 x (4π/3) r³

= 1/2 x (4π/3) (6)³

= 144π

Also volume of an oblique cone =

=volume of a right cone

= (π/3) r²h

= (π/3) 6²(14)

=168π

Volume of composite figure = 144π + 168π = 312π mm³

True or false: Two lines with undefined slopes are parallel to each other and parallel to the y axis
BlackZzzverrR [31]
Correct! lines that have undefined slopes are always parallel to the y-axis as the change in x is 0. A gradient is calculated by  the change in y divided by the change in x and anything divided by 0 is referred to as undefined.
 
\frac{y_{1}- y_{2}  }{x_{1}- x_{2} }

(calculation for a gradient)


Hope that helps sorry if its a bit confusing :)
