Answer:
Option (a)
Step-by-step explanation:
The given equation is
y = 4 (2ˣ)
To find y-intercept, substitute x=0 in the equation.
y = 4 (2⁰) = 4 (1) =4
Hence y-intercept is 4.
Since y-intercept is 4, the equation should pass through the point (0,4).
The only graph passing through the point (0,4) is the graph in option (a).
Hence the answer is option (a).
Answer:
Answer A
Step-by-step explanation:
If you use the Medium, Mean, And Range that's what it would be,
That's what I'm assuming this assignment is.
Step-by-step explanation:
(A) Let a triangle be formed with height of pole h, length of base b and angle of elevation 58°. (Due to lack of a figure).
Tan 58° = h / b = 1.6
(B) Let another triangle be formed with height of pole h, length of base (b + 90) and angle of elevation 36°. (Due to lack of a figure).
Tan 36° = h / (b + 90) = 0.72
(C) <u>Simplifying the two equations</u> :
1.6b = 0.72b + 64.8
b = 64.8 / 0.88 = 73.6 m
h (height of pole) = 1.6 * 73.6 = 117.76 m
Answer:
$32
Step-by-step explanation:
Given : you could make $8 an hour for four hours of work and you also spend about $25 each time you go to the arcade
To Find : what is the opportunity cost of going to the arcade on Saturday night
Opportunity cost is the value of something when a particular course of action is chosen. the opportunity cost is what you must forgo in order to get something.
So,the cost what you must forgo in order for going to arcade is the opportunity cost.
Since you make make $8 an hour
So, for four hours of work you make = 8*4 = $32
Hence the opportunity cost is $32
Explanation:
It means the result of your calculation doesn't differ from the actual value by more than a factor of 3 (or "something").
For example, suppose you're estimating the volume of a lake. You estimate it to be 100,000 acre-feet. If its actual volume is 265,000 acre-feet, your estimate is within a factor of 3 of the correct volume. (You are too low by a factor of 2.65.)
If your estimate were 700,000 acre-feet, you would still be within a factor of 3 of the correct value. (You would be too high by a factor of 2.64.)
___
This sort of tolerance allowance is usually specified for things that are difficult to estimate. A factor of 3 is generous, but requires you have a pretty good guess as to many of the parameters involved. For example, it may be unlikely you could estimate the number of grains of sand on a beach within such a factor. On the other hand, you could probably easily estimate the number of candies in a jar within that tolerance.
