What is Place Value?In math, every digit in a number has a place value. Place value can be defined as the value represented by a digit in a number based on its position in the number. For example, the place value of 7 in 3,743 is 7 hundred or 700. However, the place value of 7 in 7,432 is 7 thousand or 7,000.
Given here: The number 56
To convert it to 506 we must add 506-56=450
∴ we must 45×10 to 56 to convert it to 506
Hence, 45 tens must be added to get 506

y−7=2/5(x−4)
y+7=2/5(x+4)
y+4=2/5(x+7)
y−4=2/5(x−7)
Answer:
y + 7 = 2/5 (x + 4)
Step-by-step explanation:
(I hope 25 is 2/5)
The formula is y - y1 = m (x - x1), so you put the variables in to y1 and x1 plus add the slope in as m, and there you are! Point slope form. (you also have to flip the signs when putting them in, causing -4 and -7 to become 4 and 7)

Which must be larger log 15 Or In 15? And why
Answer:
ln 15 must be greater (larger than) if log 15 is common.
Step-by-step explanation:
log 15 [assumed to be a common logarithm]
‹–› 15 = 10 ^ log(15)
ln 15 [natural log which has a base of e] ‹–› 15 = e ^ ln(15).
10 > e
e ≈ 2.7218.
e is approximately 3 rounded to the nearest whole number.
Logically you would need to raise 3 to a greater power for 3ⁿ = 15. Than 10ⁿ = 15.
For example 3² < 10² → 3³ < 10³ → 3⁴ < 10⁴ → ... Thus 3ⁿ < 10ⁿ for n > 0.

A zoo maintains a small patch of bamboo, which it grows as a food supply for its pandas. Four weeks ago, the bamboo was 10 ft 7 in tall. Since then, the bamboo has grown 5ft 12 in. How tall is the bamboo now ?
bamboo has grown 5 ft 12 in. How tall is the bamboo now?
Answer:
16 feet and 7 inches
Step-by-step explanation:
To find how tall the bamboo is now, first add the number of feet together:
10 + 5
= 15
Then, add the inches:
7 + 12
= 19
This can be converted to 1 foot and 7 inches.
Then, add 15 to this:
= 16 feet and 7 inches
So, the bamboo is now 16 feet and 7 inches tall
The current height of the bamboo is given as 16 feet 7 inches tall.
Given that,

Bryce had a $25 gift card to use on songs and games at an online media store. Songs cost $2 each and games cost $5 each. Bryce spent all the money on the gift card to download 8 items. Solve the system to determine how many games he purchased. Let s represent the number of songs and g represent the number of games. s + g = 8 2s + 5g = 25 Bryce purchased games.
Answer:
Bryce purchased 3 games.
Step-by-step explanation:
To find the number of songs and games that Bryce downloaded, we need to solve the following system of equations:
s + g = 8
2s + 5g = 25
We know that:
s + g = 8 → 2s + 2g = 16 → 2s = 16 -2g
2s + 5g = 25 → 16 - 2g + 5g = 25
→3g = 25 - 16
→3g = 9
→ g = 3
Therefore, bryce downloaded 3 games and 5 songs!

In Exercises 1-3, graph AABC and its image after a reflection in the given line.
1. A(0, 2), B(1, -3), C(2, 4); x-axis
1.
2. A(-2,-4), B(6,2), C(3. – 5); y-axis
3. A(4, -1), B(3, 8), C(-1, 1); y = -2
Answer:
1. Point A: (0, 2)
Point B: (-1, -3)
Point C: (-2, 4)
2. Point A: (-2, 4)
Point B: (6, -2)
Point C: (3, 5)
3. Point A: (4, -3)
Point B: (3, -12)
Point C: (-1, -5)
Step-by-step explanation:
1.
Reflection of point A:
Reflections over the x-axis are really easy. All you have to do is change the x-coordinate to the opposite sign.
In this case, 0 does not need to change since it already lies on the x-axis.
The coordinate for A will stay the same as (0, 2).
Reflection of point B:
Again, change the x-coordinate to negative.
1 → -1
The coordinate for B will now be (-1, -3).
Reflection of point C:
2 → -2
The coordinate for C will now be (-2, -4).
2.
Reflection of point A:
Reflections over the y-axis are also really easy. This time, all you have to do is change the y-coordinate to the opposite sign.
In this case, -4 would change to just 4.
The coordinate for A will stay the same as (2, 4).
Reflection of point B:
Again, change the y-coordinate to negative.
2 → -2
The coordinate for B will now be (6, -2).
Reflection of point C:
-5 → 5
The coordinate for C will now be (-1, 5).
3.
This is going to be a bit harder than the previous two, but I know you can handle it. :)
Reflection of point A:
The x will stay the same and only the y will change.
Take the y-coordinate and subtract it from the reflection line while getting the absolute value..
|(-1) - (-2)| = |1| = 1
This means, point A is one unit down the line y = -2
(-2) - 1 = -3
The coordinate for A will now be (4, -3).
Reflection of point B:
Again, the x will stay the same and only the y will change.
Using the absolute value, get the y-coordinate and subtract it from the reflection line again..
|(8) - (-2)| = |10| = 10
This means, point A is five unit down the line y = -2
(-2) - 10 = -17
The coordinate for B will now be (3, -12).
Reflection of point C:
I think you get the gist of it.
|(1) - (-2)| = |3| = 3
(-2) - 3 = -5
The coordinate for C will now be (-1, -5).
The red triangle is the original image and the blue triangle is the image after the reflection. The purple line is the reflection line.

The graph of Exercises 1-3 that shows AABC and its image after a reflection in the given line can be done using the example from the graph attached.
What is reflection about?A reflection over line is known to be a kind of transformation where each point of the main or original figure (that is the pre-image) is said to be made up of an image that has similar distance from the reflection line.
Note that In a reflection, the image is said to be of similar size and also of the same shape as the original image.
Therefore to be able to construct the graph of Exercises 1-3, one can use the image example by tracing the number values such as A(0, 2), B(1, -3), C(2, 4); x-axis, A(-2,-4), B(6,2), C(3. – 5); y-axis and A(4, -1), B(3, 8), C(-1, 1); y = -2 on the graph and linking them up together to form an angle.

16 is 20.51% of the number 78.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let x percent of 78 is 16.
So, x% of 78 = 16
x/100 (78)= 16
78x = 1600
x= 1600/78
x = 20.51%
Hence, 20.51 percent of 78 is 16.

Vector Calculus
A particle of mass m move along the path σ(t)={t^2,sin t, cos t} Calculate the force acting on the particle t=0.
It seems like σ(t) is the positive function of the particle. Compute its acceleration by differentiating this function twice.
σ(t) = {t ², sin(t ), cos(t )}
σ'(t) = {2t, cos(t ), -sin(t )}
σ''(t) = {2, -sin(t ), -cos(t )}
When t = 0, the acceleration on the particle is
σ'' (0) = {2, -sin(0), -cos(0)} = {2, 0, -1}
Then the force acting on the particle at time t = 0 is
F = {2m, 0, -m}
by Newton's second law.

1. In a supermarket, each orange costs $3, and each apple costs $2. If you want to spend
exactly $45, write an equation in standard form modeling this situation. Let o represent
the number of oranges you buy, and a represent the number of apples you buy.
Answer:
3o + 2a = $45 ( you can buy 9 oranges and 9 apples)
Step-by-step explanation:
First I divided 45 by 3 and I got 15 so now I know that 15 is the highest amount of oranges I can buy without going over $45. I also know that 15 cannot be an answer because I also have to buy apples.
Then I divided 45 by 2 and 22 was the highest whole number.
Now I would play trial and error BUT i know that the number for oranges have to be less that 15 and the number for apples has to be less than 22.
3 times 9 equals 27 (oranges)
45 - 27 = 18
2 times 9 equals 18 (apples)
3o+2a =$45 is the equation in standard form modeling this situation.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that in a supermarket, each orange costs $3, and each apple costs $2.
Let o represents the number of oranges you buy

A party planner estimates a party will cost $200 plus $8 for each person attending. What is the y-intercept of the graph of the linear function representing the total cost of the party?
Answer:
The y intercept is 200
Step-by-step explanation:
Given
Base Cost = 200
Per person =8
Required
Determine the y intercept
First, we need to determine the equation.
The total amount (y) for x persons can be calculated using:
y = Base Cost + Amount per person * x.
This gives
y = 200 + 8 * x
y = 200 + 8x
The general expression of a linear equation is:
y = mx + b
Where b = y intercept
By comparison,
b = 200
Hence, the y intercept is 200
one school purchased 18 gallons of blue paint to decorate several of its classrooms. if each classroom needs 1 4/5 gallons of paint, then how many classrooms will get painted.
Answer:
18 gallons of paint could paint 10 classrooms.
Step-by-step explanation:
Given that the school bought 18 gallons of paint, and that each classroom requires 1 4/5 of paint to be painted, to determine how many classrooms can be painted with that amount of paint, the following calculation must be performed:
4/5 = 0.8
1 + 0.8 = 1.8
18 / 1.8 = 10
Therefore, 18 gallons of paint could paint 10 classrooms.
Explain the different types of rain
Answer:
Convectional rainfall. - Convectional rainfall occurs when the energy of the sun heats the surface of the Earth, causing water to evaporate to form water vapour. When the land heats up, it warms the air above it. This causes the air to expand and rise. As the air rises, it cools and condenses. ... If this process continues, rainfall will occur.
Orographic or relief rainfall. - Orographic or relief rainfall is caused when masses of air are forced up the side of elevated land formations, such as large mountains, often referred to as an upslope effect. The lift of the air up the side of the mountain results in adiabatic cooling, and ultimately condensation and precipitation.
Cyclonic or frontal rainfall. - Frontal or Cyclonic Rain is caused by cyclonic activity and it occurs along the fronts of the cyclone. It is formed when two masses of air of different temperature, humidity and density meets. For example meeting of moisture laden warm tropical wind with a polar air mass. A layer separating them is called the front.
