Answer:
a. From x = -2 to x = 0, the average rate of change for both functions is negative
d. The quadratic function, y = x², has an x-intercept at the origin
Step-by-step explanation:
From x = -2 to x = 0, the rate of change is negative because both functions are going in a downward slope. The quadratic function y = x² touches the x-axis right at (0, 0), meaning it has an x-intercept at the origin.
The second answer is incorrect because y = x² does not intersect the other parabola at (2, 3). The third is incorrect because y = x² + 3 does not even touch the x-axis. The fifth is incorrect because the rate of change is negative, not positive. Finally, the sixth is incorrect because y = x² + 3 does not intersect the other parabola at (2, 7). Hope this helps! Feel free to ask any questions!
Volume = 1/3 * pi * r^2 * h
= 1/3 * pi * 8^2 * 1.5 ( radius = 1/2 diameter = 1/2 * 16 = 8)
= 130.7 km^3 Answer
Answer: 1,920
Step-by-step explanation:
You would need to find how many containers of cookies they make in a hour which is 240 so than 240 times 8 is 1,920
Answer:-Sal can make 10 bracelets with 5 feet of yarn.
Explanation:-
We know that 1 foot = 12 inches
⇒1 inch=
Yarn used for 1 bracelet = 6 inches
Number of bracelets made in 5 feet
therefore, Sal can make 10 bracelets with 5 feet of yarn.
