Answer:
8,11,14,17,20,23,26
Step-by-step explanation:
Q = 3n+ 5
an=3n+5
a1=3(1)+5=8
a2=3(2)+5=11
a(3)=3(3)+5=14
a4=3(4)+5=17
a5=3(5)+5=20
a6=23
a7=26
Answer:
10⁴ seconds
Step-by-step explanation:
Given that,
A person breathes 
in about cubic meters of air per second.
We need to find time taken to breathe 2.5 cubic meters of air.
In 1 sec = m³ of air breathe
Let in x seconds, 2.5 m³ of air taken by the person.
Hence, in 10⁴ seconds 2.5 m³ of air is taken by the person.
Step-by-step explanation:
step one Distribute
x−45=8(2x+3)−18
x−45=16x+24−18
step two Subtract the numbers
x−45=16x+24−18
x−45=16x+24−18
So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
