Answer:

0.67 pounds per gallon.

Step-by-step explanation:

We have been given that a weighs 2 pounds and has capacity 3 gallons. We are asked to find density of the liquid.

\text{Density}=\frac{\text{Mass}}{\text{Volume}}

Upon substituting our given values in above formula, we will get:

\text{Density}=\frac{2\text{ pounds}}{3\text{ gallons}}

\text{Density}=0.67\frac{\text{ pounds}}{\text{ gallons}}

Therefore, the density of liquid is 0.67 pounds per gallon.

Ashton designs movie sets. For one scene, he has to hang a banner across an archway that takes the shape of a parabola modeled b
Crazy boy [7]
No question is asked so I'm not sure what you are looking for but below I calculated the point where the two equations intersect:
y - x = 4 → y = x + 4
y = - x² + 6x
x + 4 = - x² + 6x
x² - 5x + 4 = 0
(x - 4)(x - 1) = 0
 x = 4, x = 1

when x = 4, then y = x + 4 = 4 + 4 = 8 → (4,8)
when x = 1, then y = x + 4 = 1 + 4 = 5 → (1,5)

The line and parabola intersect at two points: (4,8) and (1,5)

X-intercept=2; containing the point (-5,4), using either the general form or the slope-intercept form of the equation of a line.
Rus_ich [418]
The line contains point (2, 0) and (-5, 4).
y - 0 = (4 - 0)/(-5 - 2) (x - 2)
y = -4/7 (x - 2)
7y = -4(x - 2)
7y = -4x + 8
4x + 7y = 8

the equation y= - 5.131x2+ 31.821x - 3.333 approximates the number of people standing in line to catch a commuter train x hours
ehidna [41]

We are given function: y= - 5.131x^2+ 31.821x - 3.333

Where, x is the number of hours after 5a.m.

We need to approximates the number of people standing in line to catch a commuter train at 7 a.m.

From 5 a.m. to 7 a.m. total number of hours = 7-5 = 2 hours.

So, we need to plug x=2 in the given function.

Plugging x=2 in y=- 5.131x^2+ 31.821x - 3.333, we get

y=- 5.131(2)^2+ 31.821(2) - 3.333

Let us simplify it now.

2^2= 4.

Therefore,

y=- 5.131(4)+ 31.821(2) - 3.333

= -20.524 + 63.642 - 3.333.

= 39.785 or 40 approximately.

Therefore, the number of people in line at 7 a.m. is approximately 40 people.

Option D.40 is correct option.
