Answer:
66.56 cm
Step-by-step explanation:
First, let's find the circumference of a circle with radius 8 cm.
2 * 8 * 3.14 = 50.24
Now, since we only need a 1/4 of the circumference, divide that number by 4
50.24 / 4 = 12.56
Add up the rest of the sides
12.56 + 10 + 17 + 10 + 9 = <u>66.56</u>
The answer is A since: 3^2+4^2=5^2
25=25
Considering High School level question, answer can be written as:
A system of 2 linear equations is [two] dimensional. It is a graph of [two] lines. The solutions can be [unique] solution if the graph intersects. [No] solution if the lines are parallel - meaning they have the same slope, or [Infinitely many] solutions if they are the same line.
Explanation:
when two lines are drawn on a two-dimensional plane then there are only three possible cases:
Case1: lines will intersect
In that case you will get a unique solution at the intersection point.
Case2: lines are parallel but don't touch each other
In that case there will be no point which lies on both lines so No solution.
Case3: lines are overlapping.
In that case all the points lies on both lines so infinitely many solutions.
9 I think, soo sorry if i'm wrong...
Answer:
a=-8 b=2
Step-by-step explanation:
x^2+6x-16
x^2+(8-2)x-16=0
x^2+8x-2x-16=0
X(X+8)-2(X+8)=0
(X+8)(x-2)=0
Compare with (X+a)(X+b)
Where we get a=-8 b=2
