Answer:
Step-by-step explanation:
The first case is a special case of the second one, so we will solve the question for the second case first.
Consider . Using the properties of derivatives and the derivatives of trigonometric functions we get that
We have the equation . Note that since then we have the equation
,
which implies that . Then,
Note that in this case, the value of k doesn't depend on the values of A and B. So, it applies to every value of A and B. The first case is included, since it is the case in which A=0 and B=1.
I don't really get this question but simply put, if you are in college syntax matters very much. (13-4) = 9 *(x-5) = 9x-45.. although in this case. since there isn't a bracket around 13-4. you'd multiply by the -4 first, giving you, 4x-20+30 =4x-10
Angle HDF is 135 degrees as well. Alternate exterior angles are congruent. :)
Answer:
A proportional relationship is a relationship between two quantities in which the ratio of one quantity to the other quantity is constant. A proportional relationship can be described by an equation of the form y = kx, where k is a number called the constant of proportionality.
Step-by-step explanation:
50 minutes= 5/6 hr
(1 3/4 miles)/ (5/6 hr)= 2.1 miles/hr
Hope this would help~
