Answer:
She is incorrect; Paloma's ratio of seconds travelled to feet travelled is 1:10.
Step-by-step explanation:
Her ratio is 1:10 because the first number is the number of seconds, and the second number is the number of feet. So for every 1 second, she travels 10 feet, as indicated in the original problem.
Hope this helps.
Answer:
The least tile would decrease
69- third quartile
66- median
Step-by-step explanation:
The first dot is the minimum, first line is the first quartile, second line is the median, third line is the third quartile, and the last dot is the maximum.

Answer:
y = 2
Step-by-step explanation:
For the exponential function in the form
y = a
Use ordered pairs from the table to find a and b
Using (0, 2 ), then
2 = a
(
= 1 ) , thus
a = 2, so
y = 2
Using (1, 6 ) , then
6 = 2b ( divide both sides by 2 )
b = 3
Thus the exponential function is
y = 2
F(x) = 11x² + 5x
f'(x) = 22x + 5
Hence,
f'(9) = (22 * 9) + 5 = 198 + 5 = 203
