Answer:
Givens:
Using this information we could recur to SAS postulate to demonstrate the congruence of this pair of triangles. We already have one side and one angle congruent, we just need to demonstrate that
, that will prove the complete congruence.
So, based on the given coordinates, we're able to calculate the length of each side and find if they are the same. We use this formula:

Therefore,
, because they have the same length.
Now, based on these congruences:
We demonstrate by the Side-Angle-Side (SAS) postulate that ΔABC ≅ ΔDEF.
Answer: 6 sqrt2
Step-by-step explanation:
Sqrt = square root shorthand.
In a 45-45-90, the legs can be represented as x and the hypotenuse as x root2.
12 = x (sqrt2)
12/sqrt2 = x
Let’s rationalize this by putting the square root on top:
12sqrt2 / 2
Simplify:
6sqrt2
Answer:
<em>4.5 hours</em>
Step-by-step explanation:
distance = velocity × time
The value of m is 9. See if you multiply 9 by 5 you get 45 and add two to get 47.
You can try to show this by induction:
• According to the given closed form, we have
, which agrees with the initial value <em>S</em>₁ = 1.
• Assume the closed form is correct for all <em>n</em> up to <em>n</em> = <em>k</em>. In particular, we assume

and

We want to then use this assumption to show the closed form is correct for <em>n</em> = <em>k</em> + 1, or

From the given recurrence, we know

so that






which is what we needed. QED
