Answer:
|x|=9
Step-by-step explanation:
Absolute value is |x|=9
Answer:
Step-by-step explanation:
Let the number = x
Read carefully the sentence part beginning with 4 times larger
4* something
4 times larger than the square of 1/2 the number
4 * (x/2)^2
4*(x/2)^2 = x
4*x^2/4 = x
x^2 = x be very careful how you handle this. It looks like 0 might be an answer, but it isn't. If you divide x on both sides and you allow 0, you will get 0 / 0 and that is undefined. You must exclude that possibility with some sort of statement.
x cannot be 0.
x^2/x= x/x
x = 1
The problem is illustrated by the figure shown below.
It is clear that ΔABC is a right triangle because
(a) it is inscribed in a circle,
(b) Its sides satisfy the Pythagorean theorem because
6² + 8² = 36 + 64 = 100, and 10² = 100.
Therefore, AC is the diameter of the circumscribing circle, and the radius is
r = 5.
The area of the circumscribing circle is
A₁ = π(5²) = 25π
The area of the triangle is
A₂ = (1/2) 8*6 = 24
The required area, of the circumcircle minus that of the triangle (shaded area) is
A₁ - A₂ = 25π - 24 = 54.54 square units.
Answer:
54.54 square units.
Answer:
24 is the answer...good luck
