For 3 it’s b. For 2 it’s 8. For 4 it’s the whole number
In both cases you may well benefit from graphing the functions.
Do you recognize f(x) = (x + 1)^2 - 1 as a quadratic function, whose graph is that of a parabola that opens up? By comparing this to y = a(x-h)^2 + k, we see that a=1, h= -1 and k = -1. The vertex is at (h,k), which here is the point (-1, -1). This is the minimum value of the function. Thus, the range of this function is [-1, infinity).
Now for the function f(x) = 7x - 11: This is a linear function whose graph is (surprise!) a straight line. When x increases, y increases, without limits to either. Similarly, when x decreases, y decreases.
Thus the range includes all real numbers: (-infinity, infinity).
Answer:
Step-by-step explanation:
Let d be the diameter of the wheel.
Circumference = πd
(35.325 m)/(25 revolutions) = (1.413 m)/revolution
πd = 1.413
d = 1.413/π = 0.45 m
The answer is 4^-2 = 1/16
We know that
14 days------------> 14*7 hours-----> 98 hours
98 hours*<span>$28 per hour-------> $2744
one paid day-------> </span>$28*7 hours-----> $196<span>
therefore
[</span>her true hourly wage]=[$2744+$196]/(98)-----> $2940/98-----> $30 per hour
the answer is
$30 per hour
