Which of the following illustrates the truth value of the given conditional statement?

1 answer:

5 0

Test the nature of the roots by evaluating the discriminant b^2 - 4ac:

Discriminant = 1^2 - 4 * 1 * 1 = -3

This is negative so there are no real roots of this equation

Square root of 3 is irrational

So its F T --> F

A piece of fabric is 1/3 yard by 3 5/8 yards. Irma solves 1/3⋅3 5/8 to find the area of the fabric in square yards. Enter number

Harlamova29_29 [7]

For this case we have:

The area of the piece of fabric is given by $A = a * b$

Where

$a = \frac{1}{3}yards$

$b = 3 \frac{5}{8}yards$

Substituting in the formula of the area we have:

$A = \frac{1}{3}* 3 \frac{5}{8}\\$

$A = \frac{1}{3}* (3 + \frac{5}{8})\\$

$A = 1 + \frac{5}{24}$

$A = 1\frac{5}{24}yards ^ 2\\$

Thus, the area of the piece of fabric is given by: $A = 1\frac{5}{24}yards ^ 2\\$

Answer:

$A = 1\frac{5}{24}yards ^ 2\\$

What are the zeros of the function y = x2 + 10x – 171, and why?

vagabundo [1.1K]

To find the zeros, you have to factor the equation.
y=(x+19)(x-9)
This is because 19*-9=-171 and 19-9=10.
Now to make x=0, you have to make the equation
x+19=0
and x-9=0
To solve, isolate x on both equations.
This makes x=-19 and x=9.
