Answer:
<em>x </em>= -5
Step-by-step explanation:
You have to work backwards.
53 + 7 = 60
60 ÷ 12 = 5
Add the negative »»» -5
<h3>Answer:</h3>
15.36 cm
<h3>Explanation:</h3>
The Pythagorean theorem tells you ...
... AC² = AB² + BC² . . . . . relation for face diagonal
... AD² = AC² + CD² . . . . . relation for space diagonal
Subsituting the expression for AC² given by the first equation, the second equaiton becomes ...
... AD² = AB² + BC² + CD²
... AD² = (100 cm²) + (100 cm²) + (36 cm²) = 236 cm²
Taking the square root, we have ...
... AD = √236 cm = 2√59 cm
... AD ≈ 15.36 cm
This function includes the "absolute value" function. Think: What is the domain of that function? Secondly, what is the range of y=|x-2|? Does f(x) have a lower limit? an upper limit?
Find the range of 5|x-2|. Then find the range of 5|x-2|+4. What effect does adding that 4 have on the range of y=5|x-2|?
This passage is about the domain of a function. The domain of a function is the set of all points that you can give to the function as an input.
Points not belonging to the domain are not good inputs for the function. In this example, 3 is not a good input, because if you try to evaluate the function at , i.e. if you plug 3 in place of x, you get
which is undefined, because you can't divide by 0.
So, when defining this function, you have to specify , so that the function will be defined for every other input.
