Answer:
The third graph is the graph of the given function
Step-by-step explanation:
A simple technique that can be used to identify the graph that matches the given function is; determination of the x and y-intercepts. In this case, determining the y-intercept and then using elimination will suffice in matching the function with its graph. At the y-intercept the value of x is always zero, so we replace x with zero in the right hand side of the equation; y(x) = 2^(0+3) = 8. The graph of the function should therefore cross the y-axis at the point (0,8). The third graph is the graph of the given function.
$90/10 = 9
$160/20 = 8
$80/10 = 10
$120/20 = 6
The package that has the lowest ratio cost to number of lessons is $120 for 20 lessons.

Answer:
C) 64x2 + 40x + 25
Step-by-step explanation:
we are given
we can also write as
we can use factor formula
we can compare and find 'a' and 'b'
a=8x
b=5
now, we can simplify it
so, (64x^2+40x+25) factor matches
(14)^2 - 29 196 - 29 = 167
2.3 * 12 = 27.6 tons per year
Weight at birth = 15 tons plus 27.6 tons = 42.6 tons on first birthday
