The absolute value is 40.
X means everything in algebra. It is a variable, which means that its meaning changes based on context. For example, x could be time, but it could also be cars. x is what all Mathematicians chase after and it is also the greatest tool at their disposal. x is generally called an independent variable because its value determines the output of a function. y, on the other hand, is the result of fooling around with x. It's a dependent variable, which means that y changes when x changes.
Take, for instance, the following function:
y = x + 3
Let's set x = 3.
y = (3) + 3
y = 6
As you can see, what we input as x determines what y outputs.
Answer:
1 for all evaluate questions
Step-by-step explanation:
just remember anything to the zero power is 1
the answer should be 1 1\3 that equals one hour.
Answer:
Step-by-step explanation:
The area of a sector has the formula
Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:
and simplifying that a bit to look less threatening, but not by much:
and
Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.
