<h2>Hello!</h2>
The answer is:
Since we don't have the function equation, but we have the graphic, we can use it to know what value of x makes the function equal to 0.
Finding what values of x does means that we should find where the function intercepts the x-axis.
From the graphic, we can see that the functions intercepts the x-axis at
Have a nice day!
Easy
The total area of the first shape is 42 and the total area of the second shape is 21.
The total area of the first shape is 42 and the total area of the second shape is 21.
Answer:
s ≈ - 0.5 , s ≈ 8.5
Step-by-step explanation:
s² - 8s - 4 = 0 ( add 4 to both sides )
s² - 8s = 4
To complete the square
add ( half the coefficient of the s- term )² to both sides
s² + 2(- 4)s + 16 = 4 + 16
(s - 4)² = 20 ( take square root of both sides )
s - 4 = ± ( add 4 to both sides )
s = 4 ±
Then
s = 4 - ≈ - 0.5 ( to the nearest tenth ) ← smaller solution
s = 4 + ≈ 8.5 ( to the nearest tenth ) ← larger solution
