Answer:
84 points
y= 100-2x where y= total score (0 through 100) and x= # of questions wrong (0 through 50)
Step-by-step explanation:
100- 2(8) = y
100-16 = y
84=y
Since each question (x) is worth two points (2) we have to multiply each wrong question by two (2x). And then since we're deducting point from the possible points (100) we have to subtract (100-2x)
Answer:
Step-by-step explanation:
<u>Geometric Sequences</u>
The geometric sequence is given as:
Where n is the number of the term, n≥1, and r is the common ratio.
The sum of n terms of the geometric sequence is given by:
We are given: S3=252, a1=192, thus substuting:
Dividing by 12:
Recall that:
Substituting:
Simplifying:
Rearranging:
16r^2+16r-5=0

Solving:
Both solutions are valid
Given: Principal Amount (P) = $300
The rate of interest (r) = (3/4) compounded quarterly.
No. quarters in 3 years (n) = 3×4 = 12
To find: The amount for the CD on maturity. Let it will be (A)
Formula: Compound Amount (A) = P [ 1 + (r ÷100)]ⁿ
Now, (A) = P [ 1 + (r ÷100)]ⁿ
or, = $300 [ 1 + (3 ÷400)]¹²
or, = $300 × [ 403 ÷ 400]¹²
or, = $300 × 1.0938069
or, = $ 328.14
Hence, the correct option will be C. $328.14
The graph of the function shows that function f(x) => ∞ as x = -∞ and f(x) =>-∞ as x = ∞. Option c is correct.
<h3>What is a graph?</h3>
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The curve of the function in the 2 quadrants is increasing when x tends to -∞ and in the quadrant, the curve f(x) is decreasing to -∞ as x tends to ∞.
Thus, the graph of the function shows that function f(x) => ∞ as x = -∞ and f(x) =>-∞ as x = ∞. Option c is correct.
