Answer:
50.2 in^2
Step-by-step explanation:
Using the Formula
A=πr2
d=2r
Solving for A
A= 1/4 π d^2 = 1/4*π*8^2 = 50.26548
=50.2in^2
2/3 of its capacity - 60 * 2/3 gallons = 40 gallons.
Time to fill to 2/3 is 40 / 4/5 = 40 * 5 / 4
= 50 seconds (answer)
Answer:
Step-by-step explanation:
secθ = 17/15
Answer:
No solution
Step-by-step explanation:
4(8n-1)=19+32n
Distribute the 4 to 8n-1
32n-4=19+32n
Add 4 on both sides
32n=23+32n
Subtract 32n on both sides.
Both 32n's cancel out so you are left with 0=23 which is false.
There is no solution
because in trigonometric form, the argument can take on multiple values due to the nature of trigonometry
for example, we have coterminal angles.
sin(30) + cos(30) is the same as sin(30+360n) + cos(30+360n), where n is an integer.
