Answer:
A to B = 2000 m/s
C to D = 30,000m/s
Step-by-step explanation:
A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s
C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s
Answer:
Right angle triangle goes to 15m, 8m, 17m
Step-by-step explanation:
Square root of 15^2 + 8^2 is 17
(The use of a^2 + b^2 = c^2 - Pythagoras's Theorem)
So, 10m ,11m ,15m isn't a right angle triangle
Hope this helps!
Answer:
B. The range of the function is all real numbers
A. The term "units" refers to the measurements in the original question or problem. When looking at the question, the units we are measuring are dollars/feet.
B. In this case, the f'(x) means we are looking for the cost (in dollars) to drill the next foot down.
C. Since the cost increases the more feet we drill down, the sign of f'(x) is positive.
Answer:
All trapezoids are quadrilaterals.
Step-by-step explanation:
Incorrect. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.
