Answer:
an = an-1 *7
a1 = -3
Step-by-step explanation:
We are multiplying by 7 each time
-3*7 = -21
-21 *7 = -147
The formula for a geometric sequence is
an = a1 * (r)^(n-1) where r is the common ratio and n is the term number
an = -3 ( 7) ^(n-1)
The recursive formula is
an = an-1 * r
an = an-1 *7
a1 = -3
Whenever we have to find percent, take it upon hundred and then multiply it by the number given.
Here,
20% of 60
= 20/100 × 60
= 1200/100
= 12
Therefore, 20% of 60 is 12.
Answer:
HL
Step-by-step explanation:
The two <em>hypotenuses</em> of these right triangles are marked congruent, and the <em>leg</em> QS is shared, hence congruent.
The HL theorem applies.
