Answer:
I need a picture of the prism, then I will answer the question.
Step-by-step explanation:
Answer:
Part a) The quadratic function is
Part b) The value of x is
Part c) The photo and frame together are wide
Step-by-step explanation:
Part a) Write a quadratic function to find the distance from the edge of the photo to the edge of the frame
Let
x----> the distance from the edge of the photo to the edge of the frame
we know that
Part b) What is the value of x?
Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to
in this problem
we have
so
substitute in the formula
-----> the solution
Part c) How wide are the photo and frame together?
0.3636... repeating = 4/11 .
I just recently learned how to find the fraction
that's equal to a repeating decimal.
-- Take the group of digits that repeats. (in this one, it's 36)
Write it on top of the fraction.
36 /
-- On the bottom of the fraction, write the same number of 9's .
For this one, it's 36 / 99 .
-- There's your fraction.
Simplify it if possible.
Divide top and bottom of this one by 9: 36/99 = 4/11 .
Is that cool or what !
