Answer:
D
Step-by-step explanation:
Since 1 and c are supposed to be equal, I put 2.35+0.25x=1.75+0.4x and solved that for the x. I got 4. Then, since I want to find the price of the beef, I plugged the 4 in the equation of "b" and got 3.35.
I made many mistakes when solving so I restarted many times which is why it took so long to answer. Whew, I actually found the answer though!
If you want to help, mark me brainliest, I'm only 1 away from getting virtuoso! That would make my day, and hope I made yours.
Bye!
Answer:
Change In velocity= 13.72 ms^-1
Step-by-step explanation:
fish experiences an acceleration of
9.8 m/s^2 over a period of 1.4s
Change in velocity/time= acceleration
Time in seconds= 1.4 s
Acceleration in meter per second square= 9.8 m/s^2
Change in velocity/time= acceleration
Change In velocity= acceleration*time
Change In velocity= 9.8*1.4(m/s^2 *s)
Change In velocity= 13.72 ms^-1
Answer/Step-by-step explanation (ac > b² or b² < ac.
)
A/c to question, we have to show:-
b² >ac in A.P ........ (1)
b² = ac in G.P .....(2)
b² < ac in H.P. ..... (3)
b = a+c/2 (A.P)
b = √ac ( G.P)
b = 2ac/a+c (H.P)
In A.P :
b² > ac = b² - ac
= (a+c/2)² - ac
= (a²+2ac+c²/4) - ac = a² + 2ac + c² - 4ac / 4
= a² - 2ac + c² / 4 = ( a - c ) ² / 4 > 0 Hence, b²>ac
In G.P:-
b = √ac
Hence, b² = ac
In H.P :- b² < ac = ac > b² = ac - b² = ac - ( 2ac / a+c)
= ac(a+c) - 2ac / a+c
= a²c + ac² - 2ac / a+c
= ac(2ac - 2) / a+c > 0
Hence, ac > b² or b² < ac.
