Find the real zeros 4x²-16x + 2.5x​

Mathematics
1 answer:
Lapatulllka [165]3 years ago
8 0

I am going to assume 2.5x is really 25x (typo).

First formulate the equality

4x^2-16x+25x=0 \\4x^2+9x=0 \\x(4x+9)=0 \\

Now two results emerge.

x_1=0, x_2=-\dfrac{9}{4}.

Hope this helps.

Work our the surface area of this cylinder?
tankabanditka [31]

Answer:

A=522.97\ \text{cm}^2

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 8 cm

Radius, r = 4 cm

Height of the cylinder, h = 16.8 cm

We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :

A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2\times \dfrac{22}{7}\times 4\times (4+16.8)\\\\=522.97\ \text{cm}^2

So, the surface area of the cylinder is 522.97\ \text{cm}^2
