Based on the given condition, since the rectangle is inscribed in a circle given the length to be 3x, the width can be approximated by taking the right triangle formed by the radius and the w/2, sin 45 = w/2/r, which is equal to w = 2r sin45, therefore the Area of the inscribed rectangle = LxW = (3x)(2rsin45)
Domain: possible x values
Range: possible y values
Solution: domain: all real numbers
Range: y greater than 0
<span> |9x-12| < -4
There is no solution for this inequality...
Because an absolute value is NEVER less than an a negative number </span>
Answer:
A
Step-by-step explanation:
x² - 3x - 54 = 0
x² - 9x + 6x - 54 = 0
x(x - 9) + 6(x - 9) = 0
(x - 9)(x + 6) = 0
x = -6,9
Answer:
and 
Step-by-step explanation:
Let
x -----> the number of polyphonic ringtones
y ----> the number of standard ringtones
we know that
-----> equation A
-----> equation B
Solve the system of equations by substitution
Substitute equation A in equation B and solve for y
Find the value of x
