Answer:
A. 16
Step-by-step explanation:
We have to find rate of change of function from x=3 to x=5
The average rate of change for the interval a≤x≤b is given by:
Rate of change= (f(b)-f(a))/(b-a)
In our question,
a=3
and
b=5
We can see from the table that at x = 3, the value of function is 18
So,
f(a)=18
and
At x=5, the value of function is 50
f(b)=50
Rate of change=(50-18)/(5-3)
=32/2
=16
So the rate of change of function between x=3 and x=5 is 16 ..
Option A is the correct answer..
Solution:
We have:
f(x) = √x
g(x) = 7x + b
y = f(g(x)), Given point on the graph (x, y) = (4, 6)
Use: f(x) = √x
f(g(x)) = √(g(x))
y = √(7x + b), x = 4, y = 6
6 = √(7(4) + b)
6² = (7(4) + b)
36 = 28 + b
36 - 28 = b
8 = b
b = 8
<h3>
Answer: 46 pounds</h3>
===============================================
Work Shown:
N = weight of Noah's dog = 15 & 1/3 pounds
A = weight of Aiden's dog = unknown
A = 3*N
A = 3*(15 & 1/3)
A = 3*(15 + 1/3)
A = 3*15 + 3*(1/3) .... distribute
A = 45 + 1
A = 46
Aiden's dog weighs 46 pounds.
