Answer:
no the one above it
Step-by-step explanation:
because i have had it recently
1 US dollar= 1.18 Canadian dollars
1 Canadian dollar= .85 US cents
$460 Canadian Dollars= $390.33 US Dollars
Write and solve an equation of ratios:
1 in 50 mi
--------- = ----------
x 350 mi
Then 50x=350, and x = 7 (inches)
Answer:
Part 1) The inverse function is 
Part 2) 25.75 weeks
Step-by-step explanation:
Let
x ---->the number of weeks in the course
f(x) ---> the number of assignments he has completed
we have
Part 1) Find the inverse
Let
y=f(x)
Exchange the variables (x for y and y for x)
Isolate the variable y
Let
so
Part 2) we have
where
---->the number of weeks in the course
x ---> the number of assignments he has completed
For x=50
substitute in the inverse function
Note: Juliana don't need to use the inverse function. you can just use the function you have where f(x)=50 assignments and solve for x to get the amount of weeks.
so
The equation of a circle is (x-h)^2 + (y-k)^2 = r^2. Where "x" and "y" are variables, "h" and "k" are the coordinates of the center of the circle, and "r" is the length of the radius. It is given that the center of the circle is (-27, 120). So, h= -27 and k= 120. If the circle passes through the origin, we can assume that the origin is on the circle. Since a circle's radius is constant no matter where it is drawn/is, we can find the radius of the circle by finding the distance between the circle's center (-27, 120) and the origin, (0, 0). The distance formula is: d= √((x[2]-x[1])^2-(y[2]-y[1])^2). If the coordinates of the center of the circle are (x[2}, y[2]), then x[2]= -27 and y[2]= 120. Then, the origin is the (x[1], y[1]). So, x[1] = 0 and y[1] = 0. Plugging the numbers in we get: √((-27-0)^2-(120-0)^2). This gives us √(729+14400) = 123. So since the distance between the center of the circle and a point on the circle is 123 (units), then the radius has a value of 123.
Plugging all the numbers into the equation of a circle, we get: (x-(-27))^2+(y-120)^2=123^2.
