C. 2.2
D. 4.8
Answer:
Using Pythagoras theorem.
In any right angle triangle:
As per the statement:
For the values a = 3.4 and b = 2.6, which are legs of a right triangle.
We have to find c, the hypotenuse:
Apply the Pythagoras theorem, we have;
Substitute the values we have;
then;
Therefore, the value of c, the hypotenuse, to the nearest tenth is, 4.3 units
Answer:
1200 seconds per 20 minute study session
Step-by-step explanation:
20 min x 60 sec = 1200 seconds
Answer:1,200 secs
Step-by-step explanation:
A geometric sequence is one in which consecutive terms form a fixed ratio r. In other words, if aₙ is the nth term in the sequence, then
For example, if a₁ = a is the 1st term, then
2nd term = a₂ = a₁r
3rd term = a₃ = a₂r = a₁r²
4th term = a₄ = a₃r = a₁r³
and so on. It's fairly easy to infer that
nth term =
14. We're given the 2nd and 5th terms, a₂ = -243 and a₅ = -9, and we use them to find the ratio r.
a₅ = a₄r = a₃r² = a₂r³
-9 = -243 r³
r³ = 1/27
⇒ r = 1/3
Then the 1st term is
a₁ = a₂/r = -243/(1/3) = -729
and the nth term is recursively given by
and explicitly by
15. Now we have a₄ = 1/72 and a₃ = -1/12. Using what we know about geometric sequences, we have
a₄ / a₃ = (a₃r) / a₃ = r
so that
r = (1/72) / (-1/12) = -1/6
Then the 1st term is
a₁ = a₂/r = a₃/r² = (-1/12) / (-1/6)² = -3
and the nth term is recursively given by
and explicitly by
