The x-coordinate remains the same as the x-coordinate of point B.
The y-coordinate becomes the additive inverse of the y-coordinate of point B.

Answer: B. (3, -8)

Answer:

B. (3,-8)

Step-by-step explanation:

We are given the trapezoid with point B having the co-ordinates (3,8).

Now, the trapezium is reflected across x-axis to form another trapezium.

Since, we have,

<em>Reflection across x-axis changes the co-ordinate (x,y) to (x,-y).</em>

So, we get,

The co-ordinates of B' are (3,-8).

Hence, option B is correct.

boyakko [2]
The answer in this question is 97.
0.20 SD = 1.96 SD / sqrt(n)
n = (1.96 / .200)^2
n = 96.04  
Which is rounded Up to 97
The number of observations within the data set must be greater than or equal to the quantity of 97.

The number of hours walked varies inversely with the speed of the walker. if it takes sam 12 hours to complete his walking goal
Effectus [21]
We let k be the proportionality constant for the relationship between number of hours, h and speed of the walker, s. 

                        h = k/s
Substituting the known values,
                        12 = k/5
                          k = 60

For the second scenario,
                          h = k/s
Substituting the calculated value for k and the given value for speed,
                          h = (60)(3 miles/hour)
                         h = 20 hours
                         h = 20 hours

Therefore, it will take 20 hours to walk with a speed of 3 miles per hour.

Which statements are true of the function f(x) = 3(2.5)x? Check all that apply.
Neporo4naja [7]
For this case we have a function of the form:
 y = A * (b) ^ x&#10;
 Where,
 A: initial amount
 b: growth rate (for b> 1)
 x: independent variable
 y: dependent variable
 We then have the following function:
 f (x) = 3 (2.5) ^ x&#10;
 Using the definition, the following statements are correct:
 1) The function is exponential
 2) The function increases by a factor of 2.5 for each unit increase in x
 3) The domain of the function is all real numbers

What is the domain and range of the equation y=500(1.08)^x
Marina CMI [18]
(x) is an element of a real number. This means it could be an integer, fraction or irrational number.

* As x approaches infinity, y approaches infinity.

* As x approaches minus infinity, y approaches 0.

-------------

Domain:

(x) is an element of a real number

Range:

y>0
