Finish the table using the equation. Anyone help please ! ?

solmaris [256]

Answer:

y = 0.5, 1, 1.5, 2

Step-by-step explanation:

x is twice as much as y, so when you multiply the input for y by 2, it should get the value of x. Example: if y is 1, then x is 2, because 1*2 = 2

hope this helped!

Simplify the expression. 8k - 2(4 - 3k)

DIA [1.3K]

Answer:

14k-8

Step-by-step explanation:

8k - 2(4-3k)

distributive property

8k - 8 + 6k

add like terms

8k + 6k -8

14k - 8

If anyone will look for the value of k, k is 4/7 btw but the answer to simplify the expression would be 14k-8.

The speed of a tidal wave in meters/second is given by the square root of the product of the acceleration due to gravity on Eart

fredd [130]

Answer:

70 m/s

Step-by-step explanation:

"The speed of a tidal wave in meters/second is given by the square root of the product of the acceleration due to gravity on Earth (9.8 meters/second2) and the depth of the ocean in meters":

The sentence above can be interpreted into the equation shown below (letting speed of tidal wave be "s", acceleration due to gravity be "g", and depth be "d"):

$s=\sqrt{g*d}$

Given d = 500 and g = 9.8, we find speed (s):

$s=\sqrt{g*d} \\s=\sqrt{(9.8)*(500)} \\s=\sqrt{4900}\\ s=70$

Hence, the speed is 70 meters per second.
