Answer:
a. 30 meters per second
b. -10 meters per second
Step-by-step explanation:
a. Average rate of change for the height from 0 to 6.6 secs can be calculated using the formula,
Thus,
Where,
Plug in the values into the formula:
b. Average rate of change for the height from 8.8 to 13.2 secs = tex] m = \frac{H(b) - H(a)}{b - a} [/tex]
Where,
Plug in the values:
Answer: 35
Step-by-step explanation:
You would set up the equation
25/x=20/28 cross multiply 25•28 and then divide by 20
There are several ways you can answer this. The law of cosines may be helpful. It tells you
... c² = a² + b² - 2ab·cos(C)
or
... cos(C) = (a² + b² - c²)/(2ab)
If this value is negative, then angle C is obtuse. Since 2ab is always positive, it amounts to finding the sign of
... a² + b² - c²
Of course, for repetitive calculations, a spreasheet or other machine evaluator is helpful.
The results shown in the figure indicate that side lengths {5, 7, 8} result in an acute triangle.
