Answer:
mathematicallly error sentence!
Answer:
Step-by-step explanation:
tan = opposite / adjacent
opposite side is the y-coordinate of a point on the terminal side
adjacent side is the x-coordinate of a point on the terminal side
if the terminal side is in the second quadrant (the top-left quadrant), a coordinate on the terminal side would have a negative x-coordinate and a positive y-coordinate
This being the case:
the opposite side (y) would be -3 and the adjacent side (x) would be 7
using the Pythagorean theorem:
The hypotenuse is c, so it equals 
sin = opposite / hypotenuse
so sin(theta) =
Your answer would be the one on the bottom left. I recommend the app “Mathaway” that will help you graph problems like this.
As the ratio 0.050:1 for Adalynn and the ratio 0.067:1 for Dwight are not equivalent, it shows that this is not a proportional relationship.
What is a proportional relationship?
Proportional relationships can be described as relationships between two variables that have equivalent ratios.
The ratio of Adalynn that planted 20 peach trees over 400 feet can be expressed as follows:
20:400
Divide through by 400, we have:
0.050:1
The ratio of Dwight that planted 18 plum trees over 270 feet can be expressed as follows:
Divide through by 270, we have:
0.067:1
Since the ratio 0.050:1 for Adalynn and the ratio 0.067:1 for Dwight are not equivalent, this implies that this is not a proportional relationship.

Answer:
a = 1
Step-by-step explanation:
Since x = - 1 is a zero of p(x) then p(- 1) = 0
Substitute x = - 1 into p(x)
p(- 1) = a(- 1)² - 3(a - 1)(- 1) - 1 = 0, that is
a + 3(a - 1) - 1 = 0
a + 3a - 3 - 1 = 0
4a - 4 = 0 ( add 4 to both sides )
4a = 4 ( divide both sides by 4 )
a = 1
