Answer:
15
Step-by-step explanation:
Between 2² and 3².
2√5 is gonna be a little greater than 2*2, or 4. But definitely less than 3², or 9
Answer:
11
Step-by-step explanation:
121/11=11
Answer:
-38, 62, -100
Step-by-step explanation:
I think you meant a +24, not the -24.
The recursive formula is a_n = a_(n-2) - a_(n-1)
so. we try this 3 times after the -24 term
a_3 = -4 = 2 - 6 = a_1 - a_2
...
a_6 = a_4 - a_5 = 10 - (-14) = 24
a_7 = a_5 - a_6 = -14 - (24) = -38
a_8 = a_6 - a_7 = 24 - (-38) = 62
a_9 = a_7 - a_8 = -38 - 62 = -100
a_10 = a_8 - a_9 = 62 - (-100) = 162
If the pond were a rectangle, then:
length=15 m
width=6 m
We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)
Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m
We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.
