Answer:Jarvis's class average is 75

Step-by-step explanation:

The total possible average score for the math course is 100

a) If the teacher rates homework at 10%, it means that the total possible score for homework

is 10/100 × 100 = 10

If his homework average is 93, then his score would be

(93×10)/100 = 9.3

b) If the teacher rates quizzes at 30%, it means that the total possible score for quizzes

is 30/100 × 100 = 30

If his quiz average is 82, then his score would be

(82×30)/100 = 24.6

c) If the teacher rates test at 40%, it means that the total possible score for quizzes

is 40/100 × 100 = 40

If his quiz average is 72, then his score would be

(72×40)/100 = 28.8

d) If the teacher rates final exam at 20%, it means that the total possible score for quizzes

is 20/100 × 100 = 20

If his final exam is 60, then his score would be

(60×20)/100 = 12

Jarvis's class average would be

9.3 + 24.6 + 28.8 + 12 = 74.7

Approximately 75

Evaluate the function at x = –2. A. y = –4 B. y = 0 C. y = 2 D. y = 3
lys-0071 [83]
From the graph, identify the x=-2 point on x axis,
(is it 2 units to left of origin.)

now, imagine a vertical line through it.
This vertical line intersects the given line at which point?
The y co-ordinate of this point is your answer.

From the given graph,
the vertical line intersects at (-2,3)
so y= 3 it is :)

One of the rules of logarithms is as follows;

\begin{gathered} \log _ab=x \\ Is\text{ equivalent to,} \\ a^x=b \end{gathered}

We can now insert the corresponding values in the question provided, as shown below;

\begin{gathered} \log _2\frac{1}{16}=-4 \\ \text{This is equivalent to,} \\ 2^{-4}=\frac{1}{16} \end{gathered}

Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;

a^{-x}=\frac{1}{a^x}

Therefore, our equation can now be re-written as follows;

\begin{gathered} 2^{-4}=\frac{1}{16} \\ \frac{1}{2^4}=\frac{1}{16}^{} \\ \frac{1}{16}=\frac{1}{16} \end{gathered}

However, the question requires the answer to be expressed in exponential form. Therefore,

\log _2\frac{1}{16}=2^{-4}
