Answer:
A piecewise function.
Step-by-step explanation:
The problem you showed is a <em>piecewise function.</em>
In this problem, you have to plug in 3 for the value x.
However, if you take a look at the conditions that value x has, it never says that x can equal 3. <em>Thus, this function cannot be true.</em>
<em>Way to check this input is undefined: </em>
Plug in 3 for the variable x. On the first function, your output will be 4. On the second function, your output will be 8.
According to the definition of a function, a function can have many inputs but only one output. In this case, this function has one input, that is 3, but produces two outputs.
I believe it’s just the base, radius, and maybe the total surface
Second binomial formula
(a - b)^2 = a^2 - 2ab + b^2
(3x - 4)^2 = (3x)^2 - 2 × 3x × (-4) + (-4)^2
=9x^2 + 24x - 16
Answer: 3/5 inches
Step-by-step explanation:
l= 5w+7
A = wl
w(5w+7) = 6
5w²+7w = 6
5w²+7w -6 = 0
5w²+10w-3w-6=0
5w(w+2)-3(w+2)=0
(5w-3)(w+2)=0
5w-3=0 w+2=0
5w=3 w=-2in
w=3/5in
width cannot be negative, so the width is 3/5 inches.
Notice that when
, you have
so
is a solution, and the cubic has
as a factor. This means you can divide to get another quadratic factor and thus two more solutions.
So,
You can use the quadratic formula here:
