Answer:
n = 5
Step-by-step explanation:
3 x (n+1)² = n² + (n+2)² + 34
3n² + 6n + 3 = n² + n² + 4n + 4 + 34
n² + 2n - 35 = 0
(n - 5) (n + 7) = 0
n is a positive number
n = 5
check: 5, 6, 7
6 x 6 x3 = 108
(5 x 5) + (7 x 7) + 34 = 25 + 49 + 34 = 108
Answer:12
Step-by-step explanation:
Answer:
5 1/4 is your answer.
Step-by-step explanation:
1/4 is the fraction of .25 so your answer is:
5 1/4
You can do this by comparing your equation to the general form of equation of a circle
( x - a)^2 + (y - b)^2 = r^2 where (a,b) is the centre and r = radius:-
(x + 9)^2 (y + 6)^2 = 9
so (a,b) = (-9,-6) and r = 3
so the answer is B
The distance across the lake, a is 611 yards
<h3>Right angle triangle:</h3>
Right angle triangle have one of its angles as 90 degrees. Therefore, the side a can be found using trigonometric ratios,
Therefore,
tan 47° = opposite / adjacent
tan 47° = a / 570
cross multiply
a = 570 tan 47°
a = 570 × 1.07236871002
a = 611.250164714
a = 611 yards
