The number 1 was typed into cell A1 of a spreadsheet, while in cells A2 through A9, formulas were typed in as shown. If the values produced by the formulas were displayed in the spreadsheet instead of the formulas themselves, what would be the value displayed in cell A9?
A) -2
B) -1
C) 0
D) 1

-1

Step-by-step explanation:

11

2= (A1)² - 1 = 1² - 1 = 0

3= (A2)² - 1 = 0² - 1 = -1

4= (A3)² - 1 = (-1)² - 1 = 0

5= (A4)² - 1 = 0² - 1 = -1

6= (A5)² - 1 = (-1)² - 1 = 0

7= (A6)² - 1 = 0² - 1 = -1

8= (A7)² - 1 = (-1)² - 1 = 0

9= (A8)² - 1 = 0² - 1 = -1

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
