Answer:
329.5
Step-by-step explanation:
From the table we see that the common difference d = 0.5 - (-6.5)
= 7, and 7.5 - 0.5 = 7. Also 14.5 - 7.5 = 7.
The first term a1 = -6.5.
The nth term = a1 + (n - 1)d so for our sequence we have:
49th term = -6.5 + (49 - 1)7
= -6.5 + 48 * 7
= -6.5 + 336
= 329.5 (answer).
Answer:
- 56 - 7k
Step-by-step explanation:
Given
- 7(8 + k)
Each term in the parenthesis is multiplied by - 7
= (- 7 × 8) + (- 7 × k)
= - 56 + (- 7k)
= - 56 - 7k
If the third angle of the triangle is a right angle, (if it has a "box"), then the triangle is an acute right triangle. ((depends of the third angle which is not shown))
The solution is (10,2) or x=10, y=2. Hope this helps :)
