Answer:
B. ∠WXZ ≅∠YXZ
Step-by-step explanation:
In the method of Side-Angle-Side:
We need ∠WXZ ≅∠YXZ <em>which tells us that</em>
- WX and YX are equal as isosceles.
- Angle X is equal for both of them.
- XZ has similar side.
This goes side to angle to side. Therefore its true.
Answer:
[4, 6]
Step-by-step explanation:
∑ₙ₌₁°° (x − 5)ⁿ / n²
Use ratio test.
lim(n→∞)│aₙ₊₁ / aₙ│< 1
lim(n→∞)│[(x − 5)ⁿ⁺¹ / (n+1)²] / [(x − 5)ⁿ / n²]│< 1
lim(n→∞)│[(x − 5) n² / (n+1)²│< 1
│x − 5│< 1
-1 < x − 5 < 1
4 < x < 6
If x = 4, ∑ₙ₌₁°° (4 − 5)ⁿ / n² = ∑ₙ₌₁°° (-1)ⁿ / n², which converges.
If x = 6, ∑ₙ₌₁°° (6 − 5)ⁿ / n² = ∑ₙ₌₁°° 1 / n², which converges.
So the interval of convergence is [4, 6].
To put 5/2 on a number line, you have to make the fraction a mixed number (2 1/2) then put it on a number line.
Hope this helped!!
y is 5 less then the product of 4 and x
y = 4x-5
