Ok so im not good with words and math, but i am going to try my best to explain it. first you will take 45/60 which is the 45 miles per hour. next you will put it equal to 40/x. x is how many minutes. they are set equal to each other because they are the same ratio. (i honestly dont know why you cross multiply, but you just do). you then multiply 40*60 and 45*x. this gives you 2400=45x. you then divide both sides by 45 and get 53 1/3 minutes. or 53 minutes and 20 seconds
Let's examine the given function first:
f(x) = x^2 + 1 is the same as f(x) = 1(x-0)^2 + 1.
The vertex of the graph of this function is at (0, 1).
Let x=0 to find the y-intercept: f(0)=0^2+1 = 1; y-int. is at (0,1) (which happens to be the vertex also)
Comparing f(x) = x^2 + 1 to y = x^2, we see that the only difference is that f(x) has a vertical offset of 1. So: Graph y=x^2. Then translate the whole graph UP by 1 unit. That's it. Note (again) that the vertex will be at (0,1), and (0,1) is also the y-intercept.
Answer:
If we are to treat these as two ordered pairs, then the rate of change is 1.25.
Step-by-step explanation:
To find this, use the slope equation with the ordered pairs.
m(slope) = (y2 - y1)/(x2 - x1)
m = (11 9/16 - 9 1/16)/(12 - 10)
m = (2 8/16)/2
m = 2.5/2
m = 1.25
Now we know that this could be a function since we have a constant slope.
-9+13f
Step-by-step explanation:
6f-1+7f-8
6f+7f-8-1
13f-9
Answer:
To convert degrees to radians, multiply by π180° π 180 ° , since a full circle is 360° or 2π radians. Cancel the common factor of 60 . Factor 60 60 out of 240 240 .
