Lisa is sitting on the dock beside the lake she drops a rock from her hand into the lake after the rock hits the surface of the lake the rocks distance from the lake surface changed at a rate of -3 in./s if Lisa holds her hand 3 feet above the lake surface how hot how far from Lisa's hand is the rock five seconds after hits the surface

Answers

Answer 1

Answer: 4.2495 feets

Step-by-step explanation:

Given the following :

Rate of change (speed) when rock hits the lake surface = - 3in/s

Distance or depth after 5 seconds :

Distance = rate of change * time

Distance = (- 3 in/s × 5) = - 15 inches

1 inch = 0.0833 feet

15 inches = (-15 * 0.0833) = - 1.2495 feets

Distance between Lisa's hand and lake surface = 3 feets :

Distance between Lisa's hand and rock after 5 seconds :

(3 feets + 1.2495 feets) = 4.2495 feets

Answer:The answer is 2191/370

Answer:

5.92297297297...

Step-by-step explanation:

First, I made it into a fraction and multiplied the numerator and denominator by 10: [tex]\frac{43.82}{7.4}[/tex]

Then I put it into long division format and solved.

So, these are the following steps that I did:

1. Divide 438 by 74 to get 5.

2. Multiply the quotient digit left (5) by the divisor 74.

3. Subtract 370 from 438, add a decimal point to the solution, and divide to find the remainder.

In the end, I got 5.92297297297... [ 297 will continue to repeat so this is a repeating decimal. ]

Two galaxies are shown. Galaxy U: Dust, gas, and stars in the shape of a pinwheel, relatively small in size. Galaxy NGC 1427A: Dust, gas, and stars in a nonuniform arrangement spread out over a large area. How are NGC 1427A and U different? How are they the same?

Answers

Answer:

NGC 1427A has no general shape, so it is an irregular galaxy. U has a bulge in the center and arms, so it is a spiral galaxy. They are similar in that both contain plenty of dust and gas. Both also have active star-forming sites.

Step-by-step explanation:

NGC 1427A is an irregular galaxy with no discernible shape. The spiral galaxy U has a bulge in the middle and arms.

What is a galaxy?

A galaxy is a massive clump of gas, dust, and billions of stars and their solar systems bound together by gravity.

The first galaxies were discovered in the 17th century by Charles Messier, who had no idea what they were at the time.

Messier, a proficient comet viewer, noticed many more fuzzy objects in the sky that he knew were not comets.

We would discover 64 galaxies the size of the Milky Way in a cube that now holds one galaxy the size of the Milky Way.

NGC 1427A is an irregular galaxy because it lacks a general shape. U is a spiral galaxy, since it contains a bulge in the center and arms.

They are comparable in that they both have a lot of dust and gas. Both have active star-formation sites.

Hence, they are comparable in that they both have a lot of dust and gas.

Convert from the given standard form of a linear equation to the slope-intercept form of a linear equation

Answers

Answer:

y=-1/5x+1

Step-by-step explanation:

divide both sides by 5: 1/5x+y=1

subtract 1/5x so y is alone since slope-intercept has y=mx+b: y=-1/5x+1

The slope-intercept form of the line x + 5y = 5 is y = - (1/5)x - 1.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and equation of a line in slope-intercept form is y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given, An equation of a line in the standard form x + 5y = 5.

We know the equation of the slope-intercept of the line is y = mx + b.

Therefore, The slope-intercept form of the equation x + 5y = 5 is,

5y = - x - 5.

y = - (1/5)x - 1.

Perhaps the biggest mystery is whether it is convincing evidence or a simple desire to believe that keeps the myth alive.Loch Ness is a lake in Scotland. The loch, or lake, is known for sightings of a mysterious monster. Most who see this monster, known as Nessie, describe something with a long neck and several humps above the water. Sometimes the "monster" is moving in these sightings, and sometimes it is still. Many have suggested that Nessie might be a plesiosaur (plea-see-a-soar), an aquatic dinosaur that was trapped in the loch after the last ice age.The plesiosaur theory presents several problems. First, the plesiosaur is an air breather. Such a creature would need to surface often and, therefore, be seen more frequently. Second, it's unlikely that the same creature has lived in the loch since the last ice age. Today's creature would have to be the offspring of an original plesiosaur trapped long ago. This would suggest multiple creatures in the loch (needed to produce offspring). Again, sightings would be more frequent if this were the case.So from a purely logical stand point, the existence of such a large and ancient creature is unlikely. But assume for a minute that it is possible. What would a plesiosaur need to live in an enclosed lake?Tropical waters: Scientists believe plesiosaurs were warm-blooded. Like crocodiles and alligators, plesiosaurs would need to live in warm waters. The loch is very cold with temperatures averaging about 40 degrees Fahrenheit (4.4 Celsius).Food: Like other warm-blooded creatures, plesiosaurs would need a large quantity of food. If there is a group of Nessies, then even more food would be needed. Because the loch is full of silt (underwater dust) not much light gets into the deepest areas. So the food chain, which would depend on plankton, is very weak at its base. As a result, there is probably not enough food to support such a large creature.However, the plesiosaur theory is not the only one. Many other ideas attempt to explain the sightings and "photographs." But two separate sonar surveys of the loch have not found any evidence of a creature larger than a salmon. The last survey,1 completed in 2007 by the British Broadcasting Company (BBC), involved 600 different sonar beams. Using satellite navigation systems, the team made sure every inch of the loch was searched. The team found nothing. With cell phones and digital cameras, one would think that sightings of Nessie would increase. This has not happened. The BBC team believes the legend of Nessie has endured because people see what they want to see. To prove this, the team used a fence post, raising it before groups of tourists. Afterwards several of the tourists asked to draw pictures of what they had seen drew pictures of a monster's head.1"BBC 'proves' Nessie does not exist." 27 July, 2003.http://news.bbc.co.uk/2/hi/science/nature/3096839.stmThe author includes information in a list mid way through the article.
