Answer: (8)(-4.5)

Step-by-step explanation: If you were to multiply -4.5 • -8 it would be a positive number but if you multiply (8)(-4.5) that would equal a negative number

Which statement is true?

SVEN [57.7K]

Answer:

$y=log_{1} x$ is not a logarithmic function because the base is equal to 1.

Step-by-step explanation:

A logarithmic function is of the form: $y=log_{b}x$

For a logarithmic function to exist, we must fulfill certain conditions. The conditions are

i. The base, $b$ , is greater than 0. ${b>0)$

ii. The base, $b$ , is not equal to 1. $(b\ne 1)$

iii. $x$ must be greater than 0. $(x>0)$

Now, if we observe all the choices given, we conclude that the third choice is correct as the base there is 1. If base is equal to 1, then it violates the definition of logarithmic functions. So, the correct choice is:

$y=log_{1} x$ is not a logarithmic function because the base is equal to 1.

vladimir2022 [97]

Given:

The given function is $f(x)=4x^2+2x+6$

We need to determine the value of the discriminant f and also to determine the distinct real number zeros of f.

Discriminant:

The discriminant can be determined using the formula,

$\Delta = b^2-4ac$

Now, we shall determine the discriminant of the function $f(x)=4x^2+2x+6$

Substituting the values in the formula, we have;

$\Delta=(2)^2-4(4)(6)$

$\Delta=4-96$

$\Delta=-92$

Thus, the value of the discriminant of f is -92.

Distinct roots:

The distinct zeros of the function f can be determined by

(1) If $\Delta>0$ , then the function has 2 real roots.

(2) If $\Delta=0$ , then the function has 2 real roots ( or one repeated root).

(3) If $\Delta$ , then the function has 2 imaginary roots (or no real roots).

Since, the discriminant is $\Delta=-92 \ < \ 0$ , then the function has no real roots or 2 imaginary roots.

Thus, the function has 2 imaginary roots.

Can a -150/10 be classified as both a rational number and a integer

irakobra [83]

Yes! This is because -150/10 can be simplified to be -15, which is a rational number.

The word “rational” sounds like another math word you’ve heard of before. Do you know what it is?

Well, it’s “ratio”!! Ratios can be seen in the forms x:y and x/y.

ANY RATIONAL NUMBER HAS THE ABILITY TO BE WRITTEN AS A RATIO!! This will completely exclude numbers with super long decimal points (ex: 1.2345678809928374737272828...)

This number also meets the requirements of being an integer. An integer is any whole number (this excludes decimals and fractions)

I know it’s written as a fraction. However, the fraction could be simplified, making it -15, which means this is both a rational number and an integer!!
