Given:
Length of chords of one segment = 11 and 8
Length of chords of other segment = 2 and x
To find:
The value of x.
Solution:
<em>If two chords intersect each other inside a circle, the products of length their segments are equal.</em>
Divide by 2 on both sides.
Switch the sides.
The value of x is 44.

Answer:
(b) 30
Step-by-step explanation:
The standard form of a quadratic is ...
y = ax^2 +bx +c
For such a function, the axis of symmetry is ...
x = -b/(2a)
Your quadratic function has a=-5, b=+300, so the axis of symmetry is ...
x = -300/(2(-5) = 30
The peak of the curve is on the axis of symmetry. So, profit is maximized when 30 items are produced.
_____
Of course, a graphing calculator can display the maximum of the function easily.
Answer:
He will charge $28.
Step-by-step explanation:
We know that Jamal charges $3.50 per square yard.
Now we need to find the area in the image, it may be kinda hard to see it, but we can think of the image as a rectangle of 4yd by 3yd where we subtracted the area of a square of side length equal to 2yd.
The area of the rectangle is:
A = 4yd*3yd = 12 yd^2
And the area of the square is:
a = (2yd)^2 = 4 yd^2
The area of our image (equal to the difference between the area of the rectangle and the area of the square) is:
Area = A - a = 12 yd^2 - 4 yd^2 = 8 yd^2
Area = 8 yd^2
And he charges $3.50 per square yard, then for 8 square yards he charges 8 times that amount, which is:
C = 8*$3.50 = $28
