Answer:
$32 per hour
Step-by-step explanation:
if a person makes $256 per 8 hours then we can divide 256 by 8 so that we get the unit of dollars per hour.
$256/8 hour= $32 per hour
you can write this as k=y/x
which can also be 32=256/8
33/4= $8.25 an hour
8.25 x 7= 57.75
Jeremy would earn $55.75 if he works for seven hours
we have
Find the roots
Equate the function to zero
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Square root both sides
therefore
<u>the answer is</u>
Answer:
x = 30
Step-by-step explanation:
well the two agnles are congruent so they have to equal the same angle
x+ 90 = 4x
solve for x bye subtracting x from 90
90 = 3x slove by dividing 90 by 3 getting x alone
90/3 = x
Answer:
Piecewise functions are those where the behavior of the functions is dependent on the value of x.
For example the absolute value function f(x) = |x| is the same as
f(x) = -x , x<0
= x, 0<=x
To evaluate the value of f(x) = |x|, first determine if x is less than 0, equal to 0 or greater than 0. If x is less than 0, the value of |x| is equal to the negative value of x. In all other cases it is equal to the value of x.
This is the simplest piecewise function. There are other more complex functions where the function can take on more than 2 different behaviors based on the value of x.
Piecewise functions can also be identified from their graph. These have breaks in their graph, and each segment has a different behavior that is dependent on the value of x.
The evaluation of piecewise functions is done in the following way.
- First, look at x and determine from the available behaviors which one would be followed for that particular value of x.
- Next, we substitute x in that sub-function and determine the value obtained.
This complexity of this process varies with the piecewise function being evaluated. There are many functions which have a graph of infinite pieces.
A piecewise function is a function made up of different parts. More specifically, it’s a function defined over two or more intervals rather than with one simple equation over the domain. It may or may not be a continuous function.
