omeli [17]

We know that
<span>A vessel full of water weighs 16.5kg
</span><span>when the vessel is half full, it weights 10.5kg
so
16.5 kg-10.5 kg=6 kg is the weight of half water
the weight of full water=6kg*2------> 12 kg
so
the weight of the vessel=</span>A vessel full of water-the weight of a full water
the weight of the vessel=16.5 kg-12kg=4.5 kg

the answer is
the weight of the vessel is 4.5 kg

Which equation below would result in the highest earnings, y, when the number of hours worked, x, is 20?

BartSMP [9]

Answer:

(B)

Step-by-step explanation:

(A)The given equation is:

$y=2x^2$

Substituting the value of x=20, we get

$y=2(20)^2$

$y=2(400)$

$y=800$

(B) The given equation is:

$y=2^x$

Substituting the value of x=20, we get

$y=2^{20}$

$y=1048576$

(C) The given equation is:

$y=2x+2$

Substituting the value of x=20, we get

$y=2(20)+2$

$y=42$

(D) The given equation is:

$y=|2x|$

Substituting the value of x=20, we get

$y=|2(20)|$

$y=40$

Thus, the equation $y=2^x$ results in the highest earning y.
