Answer: an = -3 · 2^n - 1
Step-by-step explanation:
In a geometric series, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
an = a1 × r^(n - 1)
Where
a1 represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
Looking at the given sequence,
a = - 3
r = - 6/ - 3 = 2
Therefore, the formula for the sequence is
an = - 3 × 2^(n - 1)
The length of each of the equal sides of an isosceles triangle are 80.
Explanation:
Given that the forest clearing is in the shape of an isosceles triangle with a base of 75 feet.
The perimeter of the forest clearing is 235 feet.
We need to determine the length of each of the two equal sides.
Length of the two sides.
Let x denote the length of each of the equal sides.
The value of x can be determined using the perimeter formula.
Perimeter of the triangle = Sum of all the three sides of the triangle.
Thus, we have;
Thus, the value of x is 80.
Hence, the length of each of the equal sides of an isosceles triangle are 80.
Answer:
2730
Step-by-step explanation:
700*39/10
700*39 = 27300
Then you divide by 10
So 2730.
