ANSWER
The correct answer is 19.1
EXPLANATION
The perimeter of triangle OQR is the sum of the distance around the triangle.
Thus,

We can observe that two of the angles are equal.
The angles that are equal measures 62° each.
Therefore triangle OQR is an isosceles triangle. This means that

Hence,

units.
True because it has 4 equal sides and 4 equal interior angles each measuring 90 degrees
It looks like the first 1 is the first problem, problem #1. (because of the period)
If this is the case, then the second sequence is 1, 0, -1, ...
1-1=0
0-1=-1
-1-1=-2
-2-1=-3
-3-1=-4
The sequence would then be 1, 0, -1, -2, -3, -4, ...
Answer:
0.03125
Step-by-step explanation:
If we have a fair coin the probability of landing a head is 50%.
We can think the question as what is the probability of landing four tails and then a head. That is we needed at least 5 tries to get a head.

Since this events are independent we can write it as

Answer:
B) Y=-2x+1
Step-by-step explanation:
(-2,5)(2,-3)
M= -8/4 = -2
y = -2x + b
5 = -2(-2)+ b
B= 1
Y=-2x+1
