Answer:
undefined
Step-by-step explanation:
The slope of a line is the ratio of the vertical change between two points to the horizontal change between those same two points. When the line is vertical, the horizontal change is zero. That means the slope is some (non-zero) value divided by zero. <em>Division by 0 gives a result that is "undefined."</em>
The slope of a vertical line is "undefined."
Answer:
1. 21 cm
2. 75 in
3. 11.25 yds
4. 9 mm
Step-by-step explanation:
1) You know the height of the bird from the observer is the same as the height of the plane to tower. We also know that the angle of depression is same as the angle of elevation.
So we will use the tangent function to find the value of x.
tan 23 = 5000 / x
x = 5000 / tan 23
x = 11779
You're answer will be 11779 feet
2) We will use the sine function.
sin 35 = 17,000 / x
x = 17,000 / sin 35
x = 29638.6
So the answer would be approximately 29639
Answer:
0.1325
Step-by-step explanation:
Weight of the first stock (w1) = .25
Weight of the second stock (w2) = .75
Expected return for the first stock (E(R1)) = .08
Expected return for the second stock (E(R2)) = .15
The expected return of the portfolio is given by the weighted average of the expected return of each stock:
The portfolio expected return, E(Rp), is 0.1325
Answer:
20 cents
Step-by-step explanation:
Divide 3 dollars by 15 caterpillars.
3/15 = 0.2
