Answer:
Step-by-step explanation:
h=-5t²+135
when t=3 s
h=-5(3)²+135=-45+135=90 m
Answer:
Step-by-step explanation:
The 9th term is the next-to-last term, where the left term of the binomial is raised to the first power, the right term of the binomial is raised to the 8th power (9-1=8), and the multiplier is 9C8 = 9!/(8!·1!) = 9. This product is ...
9·(3x)^1·(-2y)^8 = 6912xy^8

Answer:
Step-by-step explanation:
Given
Geometry Progression
Required
Calculate the second term
First, we need to write out the formula to calculate the nth term of a GP
For first term: Tn = 500 and n = 1
For fought term: Tn = 32 and n = 4
Substitute 500 for a
Make r^3 the subject
Take cube roots
Using:
and
<em>Hence, the second term is 200</em>
