Answer:
k=5/3
Step-by-step explanation:
The variables x and y vary directly. Given that, y = 20 and x = 12
We can write it as :
y=kx
Where k is constant of proportionality
Put the values of x and y
20=12k
k = 20/12
k = 5/3
So, the value of the constant of proportionality is 5/3.
Answer:
4y^4 + 6y = 256y + 6 = <u>262y</u>
Step-by-step explanation:
Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6
Simplify the first term; 4^4 = 256
Now, add 6; 256 + 6 = 262
Add back in the variable; 262y
Answer: 5^2
Step-by-step explanation:
Since the base are all the same, you will add the exponents and let the exponents stay the same.
5^3 * 5^4= 5^7 * 5^-5= 5^2
The speed would be 158.4fps and the parachutist would fall 2,376 feet during 15 seconds.
Answer:
x=5/6
Step-by-step explanation:
k=4/5
3 and 5 can go into 15
10/15 and 12/15
10/15 divided by x =12/15
x=5/6
