Answer:
6
Step-by-step explanation:
the answer would be 5.70588235294, but if you are rounding to the nearest tenth, its 6
To find the tax rate when given the initial price of an object and the final tax value, you use the equation: $350 * X = $22.75 (where X is the sales tax rate). Then solve:
$22.75/$350 = .065
So the rate is 6.5%
Answer: B. The domain is {x|x<0 or x>0} and the range is {y|y>0}
Step-by-step explanation:
f(x)=x^-2
----------------------------
#1 Any negative (-) exponents means the answer will be 1/ the term
- for example, 3^-2=1/3^2=1/9
NOTE: NEGATIVE EXPONENTS DOES NOT MEAN IT IS A NEGATIVE NUMBER, IT IS STILL A POSITIVE NUMBER IF THE BASE IS POSITIVE.
-----------------------
The domain, which will be the value of x.
x can be any real number, except 0, because 0 can't go to negative exponents or else it will be undefined.
{x|x<0 or x>0}
-------------------------------------
The range, which will be the value of y.
Since the x value is being squared, it is always positive
{y|y>0}
Answer:
15 cm
Step-by-step explanation:
The volume of a cylinder is given by
... V = πr²h
Then
... h = V/(πr²)
Substituting the given dimensions, you have
... h = (753.6 cm³)/(3.14·(4 cm)²) = 15 cm
