The position of museum relative to hotel will be (9,1) as the starting position will be (0,0) that is her hotel then the position of coffee shop is (-2,4) and at the end position of museum is (7,5).
What is coordinate?A set of values indicating an exact position. On graphs, it is typically represented by a pair of numbers: the first number represents the distance along, and the second number represents the distance up or down. The location in the cartesian plane will be defined by the coordinate points. The distance between two points is known as the x-coordinate, or abscissa, and the distance between two points is known as the y-coordinate. To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to find the y-coordinate.
Here,
The starting coordinate=0,0
The second coordinate=-2,4
The ending coordinate=7,5
The required coordinate will be
=7--2-0,5-4-0
=9,1
The position of the museum in relation to the hotel is (9,1) because the starting point is (0,0) that is her hotel and the position of the coffee shop is (-2,4) and the position of museum is (7,5).

Answer:
[tex]g(2) = 9[/tex]
[tex]x = 1[/tex]
[tex]g(0) = 1[/tex]
[tex]g(x)=3^x[/tex]
Step-by-step explanation:
To find g(2), find the y-value when x = 2.
From inspection of the graph, g(2) = 9.
To find x when g(x) = 3, find the x-value when y = 3.
From inspection of the graph, g(1) = 3, so x = 1.
To find g(0), find the y-value when x = 0.
From inspection of the graph, g(0) = 1.
Therefore, we have determined the following ordered pairs:
(0, 1)(1, 3)(2, 9)The given graph is a graph of an exponential function.
General form of an exponential function:
[tex]f(x)=ab^x[/tex]
where:
a is the initial value (y-intercept).b is the base (growth/decay factor) in decimal form.The y-intercept is when x = 0.
As the y-intercept is 1, a = 1:
[tex]\implies g(x)=(1)b^x[/tex]
[tex]\implies g(x)=b^x[/tex]
To find the value of b, substitute one of the ordered pairs into the function and solve for b:
[tex]\begin{aligned}g(x)=b^x&\phantom{=}\\\implies g(2)=b^2&=9\\ \sqrt{b^2}&=\sqrt{9}\\b&=3\end{aligned}[/tex]
Therefore, the rule for the graphed function is:

Brian is sanatizing his pool and hot tub with a bag of 63 oz powdered sanatizer. If he used 1/3 of the bag on his pool and 1/7 of the bag on his hot tub how much is left in the bag?
Answer:
33 oz
Step-by-step explanation:
63x1/3=21
63x1/7=9
21+9=30
63-30=33
33 oz of powdered sanitizer is left in the bag.
I took 1/3 of 63 first, to show how much he used on the pool. Then I took 1/7 of 63 to show how much he used on the hot tub. I added the amount he used, and subtracted them from 63 to see how much was left. He had 33 oz left in the bag. Hope this helps! Good luck! :)

Jada's water bottle holds 20 ounces of water.
Let the water bottle holds x ounces of water.
She drank 12 ounces of water.
this is equivalent to 60%
Hence 60% of x = 12
or, 0.6x = 12
or, x = 20 ounces
Therefore the bottle holds 20 ounces of water.
The English word percentage which refers to fractions with a denominator of 100, was derived from the Slang term "per centum," which means "by the hundred."
In other words, it is a connection where it is always assumed that the value of the whole is 100. The proportion of each reading to the total value is represented by the actual number whenever we have two or more readings that sum up to 100.

2) If a number is multiplied by seven, and the product is increased by two, the result is one hundred. Find the number.
ANSWER:
14
EXPLANATION:
Given that a number is multiplied by seven, and the product is increased by two, the result is one hundred.
Let's express this mathematically(equation).
Let the number be represented by X.
A number X is multiplied by seven = 7X
The product is increased by 2 = 7X + 2
The result is 100 = 7X + 2 = 100
We have:
7X + 2 = 100
Solve for X:
Subtract 2 from both sides:
7X + 2 - 2 = 100 - 2
7X = 98
Divide both sides by 7:
[tex]\begin{gathered} \frac{7X}{7}\text{ = }\frac{98}{7} \\ \\ X\text{ = 14} \end{gathered}[/tex]Therefore the number is 14
At the beginning of a snowstorm, Hassan had 2 inches of snow on his lawn.
The snow then began to fall at a constant rate of 2.5 inches per hour.
Assuming no snow was melting, how much snow would Hassan have on his
lawn 5 hours after the snow began to fall? How much snow would Hassan
have on his lawn after t hours of snow falling?
Hassan will have 14.5 inches of snow on his lawn after 5 hours of snow falling.
How to find amount snow ?Individual ice crystals that make up snow develop while suspended in the atmosphere, typically within clouds, before falling and accumulating on the ground, where they go through additional changes.
It starts out as frozen crystalline water that forms in the atmosphere under favourable conditions, grows to millimetre size, precipitates and builds up on surfaces, then undergoes a metamorphosis in place, and finally melts, slides, or sublimates away.
2 inches of snow on the lawn
Rate of snow falling = 2.5 inches per hour
Snow did not melt
Let y = height of snow on the lawn
Let t = time in hours
y = 2 + 2.5t
To find how much snow is on the lawn after 5 hours of snowing, substitute t = 5 into the found equation and solve for y:
⇒ y = 2 + 2.5(5)
⇒ y = 2 + 12.5
⇒ y = 14.5 inches
Therefore, Hassan will have 14.5 inches of snow on his lawn after 5 hours of snow falling.
