Answer:
Defined and explained in the explanation section
Step-by-step explanation:
A) Difference between a variable and a parameter is that;
A variable is simply the way in which an attribute or quantity is represented while a parameter is normally a constant value or symbol in an equation that describes a model.
B) In a family of a function like a quadratic function of say:
f(x) = ax² + bx + c.
In this example, the variable is x which is the input to the function while the symbols a, b, and c are the parameters which determine the behavior of the function f. Thus, for each value of the parameters a, b, c, we will obtain a different function.
It’s the second one because it can’t be half but it can be 1/4 and if you do the measurements you can tell it is the second one
Answer:
Cost of packing 3 boxes = 3*(2LW + 2WH + 2LH) * 0.02 dollars
Step-by-step explanation:
Assume length of box = L in
height of box = H in
width of box = W in
surface area = (2LW + 2WH + 2LH) sq. in.
surface area of 3 boxes = 3*(2LW + 2WH + 2LH) sq.in.
Cost of packng one sq. in.= 0.02 dollars
Cost of packing 3 boxes = 3*(2LW + 2WH + 2LH) * 0.02 dollars
Answer: A
<u>Step-by-step explanation:</u>
≅ ![\stackrel\frown{YZ}](https://tex.z-dn.net/?f=%5Cstackrel%5Cfrown%7BYZ%7D)
⇒ ∠XOY ≅ ∠ZOY
≅
since they are both a radius
≅
based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So,
≅
by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
Answer:
2)16.5
Step-by-step explanation:
step1:v/2.2 -0.1=7.4
add 0.1 on both sides
step2:v/2.2=7.5
multiply by 2.2 on both sides
step3:v=16.5
