Tessellation is the arrangement of congruent shapes, with no gaps and overlaps. The tessellation artwork (Picture 1) used equilateral triangles, distinguished by two designs.

An equilateral triangle has equal angles which measures 60 degrees. Hence, in this tessellation, the vertex (point where the triangles meet), total angle is 360 degrees. See picture 2 for proof.

Aiyanah made 12 withdrawals of $175.25 each from her bank account. Then she made 17 deposits of $235.66 to her same account that

Nonamiya [84]

Answer:

The overall change is $1903.22

Step-by-step explanation:

Let us approach this problem step wise

1.Firstly let us calculate all 12 withdrawal of $175.25

12*$175.25= $2103

2. Let us calculate all the deposits made 17* $235.66 = $4006.22

With these figures we can calculate the overall changes as

= $4006.22-$2103= $1903.22

flvs hope If $x^2+bx+16$ has at least one real root, find all possible values of $b$. Express your answer in interval notation.

Galina-37 [17]

If x^2+bx+16 has at least one real root, then the equation x^2+bx+16=0 has at least one solution. The discriminant of a quadratic equation is b^2-4ac and it determines the nature of the roots. If the discriminant is zero, there is exactly one distinct real root. If the discriminant is positive, there are exactly two roots. The discriminant of x^2+bx+16=0 is b^2-4(1)(16). The inequality here gives the values of b where the discriminant will be positive or zero:
 b^2-4(1)(16) ≥ 0
 b^2-64 ≥ 0
 (b+8)(b-8) ≥ 0
The answer is that all possible values of b are in the interval (-inf, -8]∪[8,inf) because those are the intervals where (b+8)(b-8) is positive.
