Answer:
1) a1 = -5, a(n) = a(n-1) + 2
Step-by-step explanation:
The explicit formula for an arithmetic sequence can be written ...
an = a1 +d(n -1)
The corresponding recursive formula is ...
a(1) = a1, a(n) = a(n -1) +d
__
Comparing the above explicit formula to the one you're given, you see that ...
a1 = -5, d = 2
Using these values in the recursive formula gives you ...
a(1) = -5, a(n) = a(n-1) +2
Answer:
Answer:
The correct answer is last option 80 cm
Step-by-step explanation:
From the given figure we can see a parallelogram LMNO
To find the perimeter of parallelogram
Here side length of the parallelogram is 18 cm and 22 cm
Perimeter = sum of side lengths
= 22 + 22 + 18 + 18 = 80 cm
Therefore the perimeter of parallelogram LMNO = 80 cm
The correct answer is last option 80 cm
Answer:
Whitney = 6
Sara = 9
Hannah = 3
Step-by-step explanation:
Let :
Whitney = x
Sara = x + 3
Hannah = x / 2
Hannah's age + Whitney's age = Sarah's age
x / 2 + x = x + 3
1.5x = x + 3
1.5x - x = 3
0.5x = 3
x = 3/0.5
x = 6
Whitney = 6
Sara = x +3 = 6 + 3 = 9
Hannah = x/2 = 6/2 = 3

Answer:
203 mililiters
Step-by-step explanation:
A scientist made 3248 mililiters of solution for a science experiment
She needs to divide them equally into 16 beakers
Therefore the amount of mililiters that will be present in each beamer can be calculated as follows
= 3284/16
= 203 mililiters
Hence 203 militers of solution will be present in each beaker
