Ericka observed the total variation in the water level over 6.2 years to be −13.64 mm. She compared this to the average annual t

rend, which shows the water level rising 1.8 mm/year. Remember, she used 6.2 years as her time period. What is the difference between how much average water levels rose and how much the water level fell in the part of the river she observed?

Answer:

In the area that she observed, the water level fell 13.64mm over 6.4 years, for an average annual rate of change of: -13.64 ÷ 6.2 = -2.2 mm/ year.

Find the product of (x − 5)2. (1 point) Group of answer choices x2 + 10x + 25 x2 − 10x + 25 x2 − 25 x2 + 25
Anuta_ua [19.1K]

Answer:

x^2 - 10x + 25

Step-by-step explanation:

Hello!

Expand the square using the Distributive Property.

<h3>Expand</h3>
  • (x - 5)^2
  • (x - 5)(x-5)

Distributive x - 5 to each factor

  • x(x - 5) -5 (x - 5)
  • x^2 - 5x - 5x+25
  • x^2 - 10x + 25

The answer is x^2 - 10x + 25.

We can also use a special binomial product formula.

Formula: (a - b)^2 = a^2 - 2ab + b^2

  • (x - 5)^2 = x^2 - 2(x)(5) + 5^2
  • (x - 5)^2 = x^2 - 10x + 25

We get the same answer both ways.

Select the correct answer. The graph of function f is shown. An exponential function with vertex at (1, 3) and passes through (m
Crank

The statement which correctly compares the two functions is that: A. they have the same y-intercept and the same end behavior as x approaches ∞.

<h3>What is a function?</h3>

A function is a mathematical expression which can be used to define and show the relationship that exist between two or more variables in a data set.

By critically observing the graph which models the function f (see attachment), we can logically deduce that the y-intercept is at four (4).

Also, from the table of function g (see attachment), we have:

At x = 0, g(x) = g(0) = 4.

In conclusion, the statement which correctly compares the two functions is that they have the same y-intercept and the same end behavior as x approaches infinity (∞).
