Answer:
B $12.69
Step-by-step explanation:
Divide 84.63 by 100 to get 1% of the bill and then multiply the answer by 15 for 15% and round it:
The closest answer would be B $12.69.
Answer: The range is y ≥ 3.
Step-by-step explanation:
When we have an equation:
y = f(x)
The range is the set of the possible values of y.
In this case, we have:
y = f(x) = 2*x^2 - 20*x + 53
This is a quadratic equation, and the leading coefficient is positive. This means that the arms of the graph will open upwards.
Then the minimum value of y will be the vale at the vertex.
We know that for a quadratic equation of the form:
a*x^2 + b*x + c
The vertex is at:
x = -b/2a
Then in this case, the vertex will be at:
x = -(-20)/(2*2) = 20/4 = 5
Then the smallest value of this function will be:
f(5) = 2*5^2 - 20*5 + 53 = 3
This is the smallest value that y can take, and y can take any value greater than 3.
Then the range can be written as:
y ≥ 3.

Answer:

Step-by-step explanation:
GIVEN: A bicycle training wheel has a radius of
. The bicycle wheel has a radius of
.
TO FIND: Approximately how much smaller, in square inches, is the area of the training wheel than the area of the regular wheel.
SOLUTION:
radius of bicycle wheel 
area of bicycle wheel 
putting value,
area of bicycle wheel 

radius of bicycle training wheel 
area of bicycle training wheel 
putting value,
area of bicycle wheel 

difference in area of bicycle wheel and bicycle training wheel



hence the training wheel is
smaller than regular wheel
