If f(x) = │(x² – 50)│, what is the value of f(-5) ?

Answers

Answer 1

Answer: $f(x)=|(x^2-50)|\n\nf(-5)=|(-5)^2-50|=|25-50|=|-25|=25\n\n\n|a|= \left\{\begin{array}{ccc}a&for&a\geq0\n-a&for&a < 0\end{array}\right\n\n|-3|=3;\ |5|=5;\ |0|=0;\ |-12|=12$

Answer 2

Answer:

Answer:

Step-by-step explanation:

f(x) = [ (x^2 - 50 ) } ,

f( - 5) = [ (-5)^2 - 50) ]

f( - 5) = [ 25 - 50]

f( - 5) = [ -25 ]

f(-5) = 25

Explaining How to Compare Water Levels Ericka decided to compare her observation to the average annual trend, which shows the water rising 1.8 mm/year. Remember, she used 6.2 years as her time period. Explain how she would calculate the difference between how much water levels rose on average and how much the water level fell in the part of the river she observed.

Answers

Step-by-step explanation:

Below is an attachment containing the solution

Answer: She would multiply the rate by the years to find the average rise in water levels, or 1.8 times 6.2 = 11.16. To find the difference between the water levels, she would subtract -13.64 from 11.16.
