Stefan measured a weight of a package as 15.375 pounds. The actual weight of the package is 15.125 pounds.What is the approximate percent error Stefan made in measuring the weight of the package?write ur answer to the nearest percent.
Part b
Alexis measured the weight of the same package and got the same percent error as Stefan. Alexis and Stefan both measured different weights of the package.
What weight in pounds did Alexis measure. Explain how u know
Answers
((15.375 - 15.125) / 15.125) x 100 = 1.652892562
You might want to round that number a 'lil
Part 2: She got 14.875 b/c with the equation there are no negative percentages, so that means that since 15.375 - 15.125 = 0.25, than 15.125-0.25 = what she got.

Answer: K
Step-by-step explanation:
Compare the equations of: h = -t² + 4t + 5 and h = -t² + 4t + 12
h = -t² + 4t + 5:
- c-value is 5
- ⇒ h-intercept is 5
- intercept form: h = -(t + 1)(t - 5)
- ⇒ intercepts are t = -1 and t = 5
- vertex form: h = -(x - 2)² + 9
- ⇒ vertex is (2, 9)
- ⇒ maximum value of h is 9
h = -t² + 4t + 12:
- c-value is 12
- ⇒ h-intercept is 12
- intercept form: h = -(t + 2)(t - 6)
- ⇒ intercepts are t = -2 and t = 6
- vertex form: h = -(x - 2)² + 16
- ⇒ vertex is (2, 16)
- ⇒ maximum value of h is 16
The only value that changed between these two equations is "c", however the h-intercepts, maximum values, and t-intercepts are all different.
This is because the c-value shifted the entire parabola up. Shifting the parabola up or down will affect the intercepts and the maximum value of the vertex.
Answer:
I only
Step-by-step explanation:
given h = - at² + bt + c
the vertex = -
Thus altering a or b effects the position of the vertex
and the maximum value is the value of the vertex
Altering c effects the h-intercept only

Treat it as a normal equation - except that you have to add fractions as coefficients rather than integers.Improper fractions will probably be best for adding because later you can cross multiply.

Answer:
Option D is correct
Step-by-step explanation:
The original polynomial is:
–2x2 + 2 + 5x3 – 5x
Arranging in decreasing power of x:
Factoring the given polynomial by grouping:
Now, (x^2-1) can be further solved using formula:
(a^2-b^2)=(a-b)(a+b)
Solving:
So, represents the factors of
Hence Option D is correct.
