Answer:
<u>h = x² - 2x - 35</u>
Step-by-step explanation:
Making the factors :
It mentions the zeros are <u>7</u> and <u>-5</u>.
Then, the factors are :
⇒ (x - 7)
⇒ (x + 5)
===========================================================
The quadratic function will be :
⇒ h = (x - 7)(x + 5)
⇒ <u>h = x² - 2x - 35</u>
Use the formula (y2-y1)/(x2-x1) from the coordinates
(3-9)/(8--7)
-6/15 reduce to get
-2/5 is the slope.
You need to be a little careful here. cot(3.14/5) ≠ cot(π/5) to the accuracy shown. 3.14 is not a useful approximation for π if you want to use more than 3 significant digits in your result.
The 2nd selection is appropriate. (1.376)
Answer:
D
Step-by-step explanation:
x^2 - 4x + 4 = 36
Take the square root on both sides.
x - 2x + 2 = 6
Answer:
the percent change is -94 %
Step-by-step explanation:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((216 - 3600) / 3600) * 100 = -94 %
Hope this helped!
