Represent the sum 1,I think,I don't know
Answer:
y=-1/2x+1
Step-by-step explanation:
We can use the points to find the slope of the line.
Equation: y₂-y₁/x₂-x₁
2-4/-2-(-6)
2-4/-2+6
-2/4
-1/2 is the slope of the line
So the equation is y=-1/2x+b
We can substitute one of the x-coordinates and the matching y-coordinate into this equation:
2=-1/2*(-2)+b
2=1+b
1=b
b=1
Therefore, the equation is y=-1/2x+1
The answer is 145 divided by tan 65 degrees.
Since the equation for tangent is opposite/adjacent, you can just plug the numbers in.
tan(65)=145/x (x being the height that you are trying to find)
tan(65) * x = 145
Then divide tan(65) to isolate the x and you get:
145/tan(65)
Hope this helps!
Answer:
Approximate percent error = 15%
Step-by-Step Explanation:
Let the percentage of error be "e"
Anticipated sales = 2,500
Actual sales = 2,125
The percentage error "e" can be calculated as per the equation below:
2500*(1-e) = 2125
(1-e) = 2125/2500
1-e = 0.85
e = 1-0.85
e = 0.15
e = 15%
Approximate percentage error = 15%
