Answer:

Step-by-step explanation:
We are given that:

And:

And we want to find:

This is a recursive formula. So we can simply substitute in each value. For instance, a₂ will be:

Thus, a₃ will be:

Finally, a₄ will be:

Answer:
C is a right triangle
Step-by-step explanation:
To determine if the triangle is right use Pythagoras' identity
A
9.4² = 88.36
6.4² + 7.1² = 91.37
88.36 ≠ 91.37 , thus not a right triangle
B
8.4² = 70.56
5.2² + 6.3² = 66.73
70.56 ≠ 66.73 , thus not a right triangle
C
9.7² = 94.09
6.5² + 7.2² = 94.09
Thus C is a right triangle
D
8.4² = 70.56
5.1² + 7.3² = 79.3
70.56 ≠ 79.3 , thus not a right triangle
Answer:
A'(-4, 3)
Step-by-step explanation:
The given point is A(-2,4).
If this point is translated by the rule:
, then we can obtain the image of A(-2,4) by plugging x=-2 an y=4 into the rule.


The correct choice is A'(-4, 3)
Answer:
0 with multiplicity 3, 3 with multiplicity 1, and 6 with multiplicity 1.
Let i = sqrt(-1) which is the conventional notation to set up an imaginary number
The idea is to break up the radicand, aka stuff under the square root, to simplify
sqrt(-8) = sqrt(-1*4*2)
sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)
sqrt(-8) = i*2*sqrt(2)
sqrt(-8) = 2i*sqrt(2)
<h3>Answer is choice A</h3>
