The amount of Moon we see changes over the month — lunar phases — because the Moon orbits Earth and Earth orbits the Sun. Everything is moving. During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon.
Answer:
Both 'The Moon is illuminated on one side by the Sun' and 'The Moon's position relative to Earth results in phases.'
Step-by-step explanation:
The Moon has phases because of its position relative to Earth, and also because it is only illuminated on one side by the Sun. As it rotates, some parts of the moon reflects the Sun's light, so it looks as if it's changing shape. The other parts that are blacked out is because it is not reflecting the Sun's light, not because of the Earth.
3)A ball is kicked from a height of 2 feet off the ground, after 1 second the ball rea
nes a height
A ball is kicked from a height of 2 feet off the ground. After 1 second the ball reaches a height of 22 feet, and it reaches its maximum height of 38 feet after 3 seconds.
• Write the quadratic equation that represents the height of the ball at any given time
• Find the height of the ball at 4 seconds
Solve the following quadratic equations
Answer:
y = - 2x + (1/2 38) + 2 = y = -2x + 19x + 2 at any second and y = -2x^2 / 2 + 19/2 + 2/2 = - x^2 + 19/2 + 2 = - x (4) + 19/2(4) + 1 = -4+ 38 + 1 = 35 seconds
Step-by-step explanation: We see that 38-2ft = 36ft and y intercept = 2 and then -2x allows us to represent the starting point 2 as -2 (1) to allow a descend to our back to 0 for y one we find y intercept we know - x^2 is our simplified equation and an input into this to find the static and slowed descend back to 0 if you keep inputting at 5 and 6 you see the equation speed up Anyway at (4) substitute = 4 seconds we divide our simplified equation a = -x2 into a b c and divide each by 2 before working out the decline of the equation (as equation still represents all ascending and descending) for the 4th second as the height was already said to be at its max at 38 feet see equation in answer to find 4 as substitute for x

Step-by-step explanation:
9514 1404 393
Answer:
4 1 3 5 2 6 (top to bottom)
Step-by-step explanation:
The statement of congruence tells you the correspondences are ...
L ⇔ H
P ⇔ J
O ⇔ U
Then the correspondences for pairs of points are ...
HU ⇔ LO
PO ⇔ JU
LP ⇔ HJ
The longest amount of time employees can work under Option A or Option B is 20 weeks. After employees work 20 weeks, they can either quit or keep making the same amount they made during Week 20. If an employee plans on quitting after 20 weeks, which payment option gives the greatest total income? Explain
Answer:
to do these word problems, just write equations that reflect the conditions. Once you have the equations, the rest is easy, right? Anyone can solve an equation; the hard part is sorting them out from the words.
So, for #1, we have
A: y = 200 + 50(x-1) = 150+50x
B: y = 200 * 1.10^(x-1)
Now you can easily make a table. See what you can do with the rest of the wowness
Answer:
Option A gives the greatest total income because every week a person keeps working they receive $50 more than the previous week they had worked compared to the $20 more they'd receive with Option B. Option A is also the better option because compared to Option B, the employees would be earning $300 by Week 3 (with Option A) compared to the $260 they'd be earning on the exact same week (with Option B)
Step-by-step explanation:
Employees earn more money working with Option A than with Option B. So, when it comes to quitting on Week 20 they'd have more money with Option A than with Option B.

Find the area of the shape 1/4 of circle radius of 2
Answer:
≈3.14
Step-by-step explanation:
The formula for finding the area of a circle is:
π·r²
π=approximately 3.14(pi)
r=radius
If you follow this formula,
you would multiply 3.14 by 2², which is basically 2x2.
2x2=4 3.14x4=12.56
But since pi is an irrational number that goes on forever, you usually round pi to the hundredths place, which would be 3.14. But since you're finding the area of 1/4 circle, you need to divide the answer by 4. 12.56/4=3.14, so the answer is about 3.14.

Answer:
2 [tex]\frac{2}{9}[/tex]
Step-by-step explanation:
First, we will turn 5 2/5 into an improper fraction:
5 * 5 = 25 + 2 = 27/5
So they worked for 27/5 days.
We want to divide the days worked by the distance to get the unit rate of distance per day:
[tex]\frac{12}{\frac{27}{5} } = \frac{12}{1} * \frac{5}{27}=\frac{60}{27}=\frac{20}{9}[/tex]
So our answer is 2 [tex]\frac{2}{9}[/tex]
Hope this helps, have a great day! :D

W
9514 1404 393
Answer:
not similar
Step-by-step explanation:
Similar polygons have all corresponding angles congruent, and corresponding sides proportional.
The sides lengths guarantee the polygons are parallelograms, so one pair of angles being congruent is sufficient to ensure that all corresponding angles are congruent.
The ratio of side lengths in the left polygon is 13/8, and the ratio of side lengths in the right polygon is 5.2/2.4 = 13/6. These are different ratios, so the corresponding sides are NOT proportional.
The figures are NOT SIMILAR.

On a bike trip, Erika rides 6 miles in the first 30 minutes and 18 miles in
the next hour. What is her average rate of speed?
Answer: 15
so the first one is 12, the second one is 18 miles per hour so if you average out the mean it's 15
Step-by-step explanation:
12 + 18 = 30 / 2 = 15
The probability that it will rain tomorrow is dependent on whether or not it is raining today and whether or not it rained yesterday. If it rained yesterday and today, there is a 20% chance it will rain tomorrow. If it rained one of the days, there is a 60% chance it will rain tomorrow. If it rained neither today nor yesterday, there is a 20% chance it will rain tomorrow. Given that it is raining today and that it rained yesterday, write a function rain_days to calculate the probability that it will rain on the nth day after today.

The length of the rectangle is 4 meters more than twice the width. The perimeter is 26 m. Find the length and the width.
Answer:
Width = 'x'
Length = 4 + 2x
Perimeter = 2 x Width + 2 x Length
86 = 2(x) + 2(4 + 2x)
86 = 2x + 8 + 4x
2x + 4x = 86 - 8
6x = 78
x = 13
Width = 13 cm
Length = 30 cm
