Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
Answer: Ray B
Step-by-step explanation:
Answer:
47/12, or 3 11/12
Step-by-step explanation:
9 1/2 - 5 7/12 > convert to improper fractions
19/2 - 67/12
make same denominator (12)
19/2 * 6 = 114/12
114/12 - 67/12 = 47/12
Answer:
AB = 3
Step-by-step explanation:
AB = AD
AB² + 4² = (AB + 2)²
AB² + 16 = AB² + 4AB + 4
combine like terms:
4AB = 12
AB = 3
The height could be 2 inches and the width could be 4 inches which means it's a total of 8 squared inches
