Hello!
First you find what numbers give you the same perimeter
9 + 9 + 6 + 6 = 30
5 + 5 + 8 + 8 = 26
7 + 7 + 4 + 4 = 22
6 + 6 + 8 + 8 = 28
The choice that has the same perimeter is D
The answer is D) 6 centimeters by 8 centimeters
Hope this helps!
Answer:
The inverse i.e f^-1 (x) is (x-1)/2
Step-by-step explanation:
The main method for finding inverse function is as follows:
We let y =f(x), and write the function as y = 2x + 1.
Next, we swap the x and y, then rearrange to make y the subject. So i.e:
x = 2y + 1 (just swapping x and y)
x - 1 = 2y
y = (x-1)/2 (solving for x).
So f^-1 (x) = (x-1)/2
Answer:
No its nonportional
Step-by-step explanation:
proportional relationship doesn't have any operation between the “k” and “x” where K is the unit rate or the constant of proportionality.
Answer:
The point that divides the directed line segment from J to K into a ratio of 5:1 is (6, 0), its y-coordinate is 0.
Step-by-step explanation:
We take J as point one, with coordinates (x1, y1) = (1, -10) and K as point two with coordinates (x2, y2) = (7, 2)
The "run" is the change in the x-coordinates: x2 - x1 = 7 - 1 = 6
The "rise" is the change in the y-coordinates: y2 - y1 = 2 - (-10) = 12
For the partition ratio, let the numerator = a and the denominator = b.
The coordinates of the point P (x, y), which divides the directed line segment from J to K into a ratio of 5:1 is:
x = x1 + a/(a+b)*run
x = 1 + 5/(5+1)*6
x = 6
y = y1 + a/(a+b)*rise
y = -10 + 5/(5+1)*12
y = 0
Answer:
Maximum value is y=24 when x=20
Step-by-step explanation:
The maximum value of the downward parabola is its vertex. Since the vertex is (20,24) then the maximum value is y=24 when x=20
