Mathematics
1 answer:
Black_prince [1.1K]4 years ago
4 0

Answer:

<em>82.2 (the last option)</em>

Step-by-step explanation:

<u>Weighted Sum</u>

When we get a sequence of values a,b,c... and we want to know the sum of all but with different percent weights pa,pb,pc... where pa+pb+pc...=100%, we compute the weighted sum as

S=a.pa+b.pb+c.pc...

The student got this final grades: tests 86, project 76, reviews 77 and their relative weights are tests 60% (0.6), book review 20% (0.2), project 20% (0.2)

The final grade is

s=86(0.6)+76(0.2)+77(0.2)

S=82.2

How can I draw this problem?
Annette [7]

Using translation concepts, the graph of f(x) is given at the end of the answer.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The parent absolute value function is given by:

f(x) = |x|

Which has the graph in the format of a V centered at the origin.

The translated function is given by:

g(x) = -1/2|x + 4| + 2.

The translations are as follows:

  • Reflection over the x-axis, due to the multiplication by the negative number, thus the V is pointing down now.
  • Vertical compression by a factor of 2, due to the division by 2.
  • Shift left of 4 units, as x -> x + 4.
  • Shift up of 2 units, as y -> y + 2.

Due to the last two translations, the graph is now centered at (-4,2) and is given at the end of the answer.
