Answer: D=96

Step-by-step explanation:

You must add 2 to both sides of the equation:

3x^2-10+2=-2+2\\3x^2-8=0

You can find the discriminant of the quadratic equation given in the problem with the formula shown below:

D=b^2-4ac

Based on the given equation, you have that:

a=3\\b=0\\c=-8

Susbstitute values. Then you obtain:

D=0^2-4(3)(-8)=96

Y = (x) = (1/16)^x<br> Find f(x) when x = (1/4)
Naddik [55]

Answer:

1/2

Step-by-step explanation:

(1/16)^x

Let x = 1/4

(1/16)^ 1/4

Rewriting 16 as 2^4

(1/2^4)^ 1/4

We know that 1 / a^b = a^-b

(2 ^ -4)^ 1/4

We know that a^b^c = a^(b*c)

2^(-4*1/4)

2^-1

We know that  a^-b = 1/ a^b

2^-1 = 1/2^1 = 1/2

Consider the following word problem. Imagine that Dr. White of the French department, Dr. Black of the English department, and D
Anestetic [448]

A word problem is used to solve problems in mathematics without the explicit use of equations initially.

<h3>What is a Word Problem?</h3>

This refers to the use of words to generate an equation that can be solved by mathematical means.

Hence, we can see that because the question is incomplete, we can infer that there is a relationship that exists between Dr. White, Dr. Black, Dr. Brown, and a woman that does not have brown hair, and equality would be used to solve it.
