Answer: 
Step-by-step explanation:
Let the given parabolic mirror opens upwards and vertex=(0,0)
Focus point of the parabolic mirror is located 2 inches from the vertex of the mirror. ∴ p=2
Since, the parabola opens upward, then the equation of the parabola is of the form 
Substitute the value of p=2 in this, we get the equation of the parabolic mirror
Hence, the equation of the parabola that models the cross section of the mirror is
Answer:
$ 93.804 or $93.80 after rounding.
Step-by-step explanation:
Answer:
The fraction 1/3 is not equivalent to a a terminating decimal, the fraction is equivalent a number that does not terminate (repeating decimal)
Step-by-step explanation:
we know that
A <u>terminating decimal</u> it's a decimal with a finite number of digits.
A <u>repeating decimal </u>is a decimal that has a digit, or a block of digits, that repeat over and over and over again without ever ending
In this problem we have
1/3=0.33333333...
The digit 3 repeat over and over and over again without ever ending
therefore
The fraction 1/3 is not equivalent to a a terminating decimal, the fraction is equivalent a number that does not terminate (repeating decimal)
Answer:
a. 2
b. -1 or 2
Step-by-step explanation:
When the funtion h(x) is at 0, or h(0), the y value is visibly shown to be at 2. When the function's y-value is at -2, you need to find the x values which make that the case. You can see that at x=-1, the y value is at -2, making this our first value. You can also see the function meet -2 when x =2, making this the second value. Hope this helps!
