Answer:
13 1/3 miles
Step-by-step explanation:
inches/miles = inches/miles
3/10 = 4/x
3x = 40
x = 13 1/3
They are proportional because as one goes up, so does the other.
Answer:
M and P
Step-by-step explanation:
they do not cross each other
Answer:
The ratio of the slant heights of the two cones will also be n : m.
Step-by-step explanation:
See the attached diagram.
If we take the vertical sections along any diameter of the base circle of the cones A and B then the triangular sections as we get will be similar.
Now, ratio of the base of the triangles A and B i.e. the ratio of the diameters of the cones A and B will be 2n : 2m = n : m and this will be the same as the ratios of other two sides of the triangles A and B.
Therefore, the ratio of the slant heights of the two cones will also be n : m. (Answer)
I don't think you copied it correctly, but I'll assume that you did.
y = 4x³ - 2x² + 5('x' to the -3.7 power) - 6
"y-prime" (the first derivative) = 12x² - 4x - 18.5('x' to the -4.7 power)
