Alexis has the following grades in his math class: Homework grades: 80, 100, 90, Quiz grades: 84, 90, 72, Test grades: 64, 72. I
vitfil [10]

Answer:

74

Step-by-step explanation:

Average is the sum of all the numbers divided by the number of numbers.

We will take average of Quizzes, Homeworks, and Tests. And multiply that by respective weights and find the weighted average of the 90%.

Quiz Avg:

(84+90+72)/3 = 82

Homework Avg:

(80 + 100 + 90)/3 =  90

Test Avg:

(64+72)/2 = 68

Now, weighted avg = \frac{90(0.1)+82(0.2)+68(0.6)}{0.9}=73.55

Rounding it off, we get "74", the correct answer.

Which function describes the vertical shift up 2 units and left 2 units to the original function: f(x) = ex
Marrrta [24]

Answer:

g(x) = e^(x + 2) + 2

Step-by-step explanation:

First, let's describe the shifts.

Vertical shift.

For a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

If N is positive, then the shift is upwards.

If N is negative, then the shift is downwards.

Horizontal shift.

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x - N)

If N is positive, the translation is to the right

If N is negative, the translation is to the left.

Now let's solve the question.

f(x) = e^x

First, we have a vertical shift up of 2 units, then:

g(x) = f(x) + 2

Now we have a shift to the left of 2 units:

g(x) = f(x - (-2)) + 2

g(x) = f(x + 2) + 2

Then:

g(x) = e^(x + 2) + 2
