Answer: Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (3, -1)
Focus: (3, - 3/4)
Axis of Symmetry: x = 3
Directrix: y = - 5/4
Step-by-step explanation:
graph{3x/(x^2-1) [-18.02, 18.02, -9.01, 9.02]}
Answer:
Since this is a proportional relationship,
We know that the number which are proportional are a multiple of each other
the number which we can multiply one of the numbers to get the other number is the constant of proportionality
we could check for proportionality by using the following formula:
p1 / s1 = p2/s2 = p3/s3 = p4/s4 if they were equal, we can say that the relation is proportional
The value of any of the above values, p1/s1 , p2/s2 , p3/s3 , p4/s4 is the constant of proportionality
Therefore, the constant of proportionality = 20 / 5 = 4
Basic amount that Edgar Anderson earns per week = $300
Sales of Mr. Anderson for one week = $2500
Percentage of commission on sales above $1000 = 15%
Then
Amount of commission
earned for the week = [2500 - 1000] * (15/100) dollars
= 1500 * (15/100) dollars
= 15 * 15 dollars
= 225 dollars
Then
Gross pay of Edgar Anderson for the week = (300 + 225) dollars
= 525 dollars
So the gross pay of Edgar Anderson for the week is $525.
Answer:
0.0625
Step-by-step explanation:
11^-x = 1/(11^x). if that equals four, 11^x = 0.25. 0.25^2 = (11^x)^2 = 11^2x. 0.25^2 = 0.0625. Hope this helps.
Answer:
The distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
Step-by-step explanation:
Given the points
Finding the distance between (-1, 1) and (2, -4) using the formula
substitute (x₁, y₁) = (-1, 1) and (x₂, y₂) = (2, -4)
units
or
units
Therefore, the distance between two points ( -1,1) and (2,-4) is:
or d = 5.8 units.
