Answer:

Step-by-step explanation:

5). \frac{1}{x^{-9}} = \frac{1}{\frac{1}{x^9} }

     = x^{9}

6). \frac{1}{x^{-2}}=\frac{1}{\frac{1}{x^2} }

      = x²

7). x^{-6}=\frac{1}{x^6}

8). \frac{1}{x^{-7}}=\frac{1}{\frac{1}{x^7} }

           = x^{7}

9). x^{-8}=\frac{1}{x^8}

10). \frac{1}{x^{-3}} = \frac{1}{\frac{1}{x^{3}}}

            = x³

(1, 2), (2, -1), (3,0), (4, 1), and (5, 1) Do those points represent a function? Explain why or why not.
eduard

Answer:

The relation is a function

Step-by-step explanation:

Given

(1, 2), (2, -1), (3,0), (4, 1),\ and\ (5, 1)

Required

Determine if the points is a function or not

A relation can be expressed as: (x_1,y_1), (x_2,y_2),(x_3,y_3)......(x_n,y_n)

Where

x = domain

y = range

When any domain element occurs more than once, then the relation is not a function.

The domain of the above points are:

x = \{1,2,3,4,5\}

In this case, no domain occur more than once; in other words, no x value occur more than once

<em>Hence, the relation is a function</em>

Help!!!? Does anyone know the answer to this question!!?
Likurg_2 [28]

Answer:

15.75

36

15.75

Step-by-step explanation:

Formula

the relationship between these two secants is NQ * NP = NM * LM

Givens

  • NP = 32
  • NQ = x
  • NM = 14
  • NL = 14 + 22 = 36

Solution

x*32 = 14*36                 Substitute values. Divide by 32

x = 14 * 36/32               Multiply 14 and 36    

x = 504/32                   Divide by 32

x = 15.75

The answer to the first box is 15.75 or x

The answer to the second box is

LM is assumed to be 22 So LN = MN + LM = 22 + 14= 36

QN = 15.75 is the third answer.

The discriminant explains how many solutions the quadratic function has. It is found using this formula:

b^2-4ac

Using the formula, there are three rules. Let's say the discriminant=d:
d<0 - No solution ø
d=0 -ONLY 1 solution
d>0 -2 solutions

In the following graph, there are no solutions as the graph does not hit the x-axis at any point. Thereafter, the discriminant MUST be less than zero. Let's view the options check which one agrees with our answer.

A - Discriminant is greater than 0, which means two solutions. This is WRONG.
B - Discriminant is less than 0, which means no solutions. CORRECT!
C- Discriminant is equal to 0, which means one solution. WRONG!

Your answer is B.
