Answer:
Step-by-step explanation:
The temperature falls from 0 degrees to -12.4
0-(-12.4) = 12.4
12.4/13.4 degree per hours
0.9185 degrees/ hour

Answer:
The magnitude of vector ab |M| = √26
Step-by-step explanation:
Mathematically, the magnitude of the position vectors is the distance between the two position vectors.
So in this case;
|M| = √{(x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2}
From the question;
(x1,y1,z1) = (2,-1,4)
(x2,y2,z2) = (1,3,1)
Substituting these values, we have
M = √(1-2)^2 + (3-(-1))^2 +(1-4)^2
M = √(1 + 16 + 9
M = √26
Answer:
i) x= -0.25, x=1.25
ii)x=1.5, x= -0.5 (notice the negative signs)
Step-by-step explanation:
So, to simply solve this(or estimate), notice what the equations say at the end of them!
0 and 2, and also notice the equations are exactly the same as the graph's.
This means, by substitution, we are look for the x-values at y=0, and at y=2
(because they are exactly the same, in those instances, we can just replace the equation with the value of 0, or 2 because they are equal)
Then all we have to do is imagine the lines of y=0(x-axis) and y=2, and find where the parabola intersects those lines.
And so, just find where they intersect, and you have got it!
Hope this helps!
