Find the value of the discriminant for <img src="https://tex.z-dn.net/?f=7x%5E%7B2%7D%20%2B5x%2B1%3D0" id="TexFormula1" title="7

Answer:

No real roots

Step-by-step explanation:

Given

7x² + 5x + 1 = 0 ← in standard form

with a = 7, b = 5, c = 1

To determine the nature of the roots use the discriminant

Δ = b² - 4ac

• If b² - 4ac > 0 then roots are real and distinct

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 then the roots are not real

Here

b² - 4ac = 5² - (4 × 7 × 1) = 25 - 28 = - 3

Thus the 2 roots are not real

A wedge of cheese is shaped like a triangular prism. The wedge of cheese is 7 inches tall. The base of the cheese is shaped like

Gala2k [10]

Answer:

193 in

Step-by-step explanation:

Volume of a triangular prism:

The volume of a triangular prism is the base area multiplied by the wedge, that is:

$V = A_bw$

The base area is one half times the triangle base times it's height, so:

$V = 0.5*b*h*w$

The wedge of cheese is 7 inches tall.

This means that $w = 7$

The base of the cheese is shaped like a triangle with a base of 11 and a height of 5 inches.

This means that $b = 11, h = 5$

Volume:

$V = 0.5*b*h*w = 0.5*11*5*7 = 192.5$

Rounding, approximately 193 in.
