When your grandmother got out of the hospital, she was so excited that she gave you some money. You decided to go to Canada where the exchange rate is 1.06 Canadian dollars to $1 US dollar as of November 2015. You have $10,000 to take with you. How many Canadian dollars do you have to spend? (Show all work using dimension analysis, round to nearest cent if necessary)
Answer:
10,600 Canadian dollars
Step-by-step explanation:
[tex] \frac{1.06}{1} = \frac{x}{10000} [/tex]
[tex]x = 10000(1.06) = 10600[/tex]

The midpoint of AB is (2,7) and point A is located at (5,-3).
What are the coordinates of point B?
The coordinates of point B =(5,10)
what is coordinates?
Coordinates are a set of values which helps to show the exact position of a point in the coordinates plane.
step - by - step explanation
5-2 = 3
2-3= -1 = the x coordinate of B
-7-3= -10
-7-10 = -13 = the y coordinate of B
(-1, -13) is the point B
A is 3 to the right of the midpoint ,so B is 5 to the left to the midpoint
A is 10 up from the midpoint so B is 10 down from the midpoint.
so the coordinates of point B is (5,10)

10. A 300-room hotel collects $125 per occupied room and does not collect any money for vacantrooms. Which of the following functions best represents how many dollars, d, the hotel generates ifthere are v vacant rooms in the hotel?O d = 125(300 + V)O d = 300(75 - v)O d = 300(75+)O d = 125(300 - V)
If there are v vacant rooms, the number of occupied rooms is 300-v (in total there are 300 rooms).
As every occupied makes the hotel collect 125, the dollars the hotel generates are:
[tex]d=125(300-v)[/tex]It means that the correct answer is the last option.

find the equation of a parabola with a focus of (0, -1) and directrix y = 1
Solution
For this case we see that the focus is (0,-1)
And the directrix is y=1
So then we have a parabola that open downwards:
The vertex is given by V= (h,k)
The focus is given by: F = (h, k+p)
And the directrix is given by: y= k-p
So then replacing we got:
1 = k-p (1)
h = 0
k+p = -1 (2)
Using equation (1) we got k:
k = p+1
Replacing into second equation we got:
p+1+p = -1
2p = -2
p= -1
k = -1 +1= 0
Then the vertex is given by: V= (0, 0)
And the formula is given by:

Here are two expressions whose product is a new expression, A: 1. What could we put in the boxes to make A be a polynomial?
We are given the following product:
[tex](-2x{}^3+B)(x^n+15)=A[/tex]For "A" to be a polynomial the value of the first box "B" must be a constant or a term of the form:
[tex]ax^n[/tex]We will use a constant. We will substitute the first box for "1":
[tex](-2x^3+1)(x^n+15)=A[/tex]For the second box, we need to use an exponent that is a positive whole number.
We will use 2:
[tex](-2x^3+1)(x^2+15)=A[/tex]With these values, the result of the product is a polynomial.

If there is no correlation between x and y, that just means that there's no relationship, connection, or interdependence between the two variables
No correlation means that as the x-values increase, the y-values have no effect

ASAP FREE PONTS! HELP! The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over time, x, measured in seconds. Use the constraints of the real-world situation to predict the height of the water balloon at 15 seconds. Use complete sentences to support your answer.
The height of the water balloon at 15 seconds based on the potential rupturing effect of the balloon's initial gravitational potential energy on the membrane of the balloon upon impact with the ground and that addition forces are not added, is at the ground level or zero feet.
What is gravitational potential energy?Gravitational potential energy is the energy possessed by a body by virtue of its elevation above ground level.
The points on the path of the water balloon thrown from the building's roof are;
(0, 4), (2, 7), (7, 5), (6, 4), (9, 1), (9.5, 0)
The location of the water balloon, 9.5 seconds after it is thrown off the roof is therefore at the point, h(9.5) = 0 feet, which can be taken as the ground level or base of the building.
According to Newton's third law of motion, which is a physics or natural law, and which states that all bodies remain at rest or continue perpetually in a straight line unless acted upon by a force.
Given that no additional force is specified after the water balloon is thrown from the building, and that a water balloon can be treated as a large drop of water, where the elastic balloon membrane, represents the surface tension holding the large droplet together, we have that the energy of impact of collision of the balloon when it lands, which is obtained from the initial gravitational potential energy of the water balloon, can potentially rupture the membrane, such that the water is spilled and remains on the floor, well after 9.5 seconds, such that at 15 seconds, the height of the balloon remains at ground level.

The zero of the linear function will be at (1, 0).
A linear function is the one which can be represented in the form y = ax + b where a, b are coefficients and x, and y are independent and dependent variables respectively. The zero of a line is the point where the line crossed the x-axis which is also known as the x intercept. The equation of the line in slope intercept form is given as y = mx + c where m is the slope and c is the y intercept. The slope of line from points (0, 5) and (2, -5) can be found by m = -5 - 5/2 -0
m = -10/2
m = -5
Now, putting this and the point (0, 5) in y = mx + c we get
5 = -5×0 + c
=> c = 5
Now, equation of line is y = -5x + 5 and for x intercept we put y = 0
0 = -5x + 5
5x = 5
=> x = 1
=> (1, 0) which is the required point
