Answer:
a≈15.56
Step-by-step explanation:
a=√A
=√242
≈15.55635
Setting y=0, we can solve the quadratic equation or factor the polynomial to
(5x-1)•(5x-1) = 0
(5x-1)^2 = 0
5x-1=0
x=1/5 or 0.2
So there is only one root and the function intersects the x-axis at only one point.
The answer is B. 1.
I may be wrong but I think a senior citizen ticket costs $8.00 and a student ticket costs $14.00
Hope I helped! :)
Answer:
The inverse f-1(x) = (2 - x)/4 + 1.
Step-by-step explanation:
Let y = -4 /(x - 1) + 2
-4/(x - 1) = y - 2
x - 1 = (y - 2) / -4
x = -(y - 2)/4 + 1
x = (2 - y)/ 4 + 1
Now replace x by f-1(x) ( the inverse) and y by x:
f-1(x) = (2 - x)/4 + 1.
Answer:
Length: 12 meters
Step-by-step explanation:
Step 1:
Let us start with the formula of the perimeter of a rectangle, , where <em>l</em> represents the length of the rectangle, and <em>w</em> represents the width of the rectangle.
We can set width as variable <em>x</em>. We are also given that the length is three times the width, hence it can be represented as <em>3x</em>.
Step 2:
We can now write our equation and solve for <em>x</em> :
We set <em>x</em> as width, so the width is 4 meters. However, in this problem we are looking for the length. The length is three times the width, so it would be meters.
