2.Make a table & Graph the function f(x) = 2)*х-1012y
We are given the function
f(x) = 2(1/2)^1
Firstly, let f(x) = y
Then, y = 2(1/2)^x
To find y, substitute the value of x into the function.
y = 2(1/2)^x
Find y, when x = -1
y = 2(1/2)^-1
y = 2 ( 1/ 1/2)
y = 2(2 x 1 / 1)
y = 2 x 2
y= 4
When x = -1 , y = 4
find y, when x = 0
y = 2(1/2)^0
In mathematics, anything raise to the power of zero is 1
Therefore, (1/2)^0 = 1
y = 2 x 1
y = 2
When x = 0 , y = 2
find y, when x = 1
y = 2(1/2)^1
y = 2 * 1/2
y = 2/2
y = 1
when x = 1, y= 1
find y, when x = 2
y = 2(1/2)^2
(1/2)^2 = (1/4)
y = 2(1/4)
y = 2x 1/4
y = 2/4
y = 1/2 or 0.5
When x = 2, y= 1/2 or 0.5
The new table becomes

What are tautologies and contradictions?When a logic statement is always true, no matter the inputs, it is called a tautology. Otherwise, when a statement is always false, no matter the inputs, it is called a contradiction.
If the statement can be either true or false, depending on the boolean values of the inputs, the statement is called contingent.
The statement given in this problem is as follows:
~(p v (p ^ q))
From the precedence of operations, it is found that:
p ^ q can be either true or false, true if p = q = 1, false otherwise.p v (p ^ q) is false if p = q = 0 and true otherwise. ~(p v (p ^ q)) is the negation of the above statement, that is, true if p = q = 0 and true otherwise.Since the statement can be either true or false, depending on the boolean values of p and q, it is classified as contingent, and option c is correct.

A tennis racket at Sport City costs $180and is discounted 15%. The same modelracket costs $200 at Tennis World and is onsale for 20% off. Which store is offering thebetter deal? Explain.
We can find the discounted price of the tennis racket at Sport City by finding the 100% - 15% = 85% of the total price. We can do this by multiplying the total price by the decimal form of 85%:
[tex]180(85\%)=180(0.85)=153[/tex]then, we have that the price of the racket at Sport City is $153
Doing the same but with the price at Tennis World, we get:
[tex]\begin{gathered} 100\%-20\%=80\% \\ \Rightarrow200(80\%)=200(0.80)=160 \end{gathered}[/tex]since the price of the tennis racket is $160 at Tennis world, we can clearly see that Sport City offers a better deal (since 153 < 160)

Find the perimeter and area of a triangle with a base of 9 cm, height of 9.3 cm, and sides of 12
cm and 19 cm. Round to the nearest hundredth when necessary.
Answer:
P(perimeter) = 40 cm A(area) = 41.85 ≈ 41.9 cm
Step-by-step explanation:
To find the perimeter of any shape, you just add the length of the sides together. Therefore, you would add the base, 9 cm, with the sides, 12 and 19 cm. 9 + 12 = 21 + 19 = 40 cm, so the perimeter is 40 cm.
To find the area, you need to use the formula for the area of triangles, which is [tex]\frac{1}{2} bh[/tex], where b = base and h = height. So, you would plug the numbers in to get [tex]\frac{1}{2} (9)(9.3)[/tex]. This equals [tex]\frac{1}{2} (83.7)[/tex], which equals 41.85 cm. Since the question says to round to the nearest hundredth, the final answer would be 41.85 ≈ 41.9 cm.

Describe the key features of the graph of the quadratic functionf(x) = -5x^2+5.A. Does the parabola open up or down?B. Is the vertex a minimum or a maximum?C. Identify the axis of symmetry, vertex and the y-intercept of the parabola.
The graph of the function will be something like this.
To make the graph correctly we can give values to x to find points in the plane
[tex]\begin{gathered} f(x)=-5x^2+5 \\ x\text{ | f(x)} \\ -2|-5(-2)^2+5=-15 \\ -1|-5(-1)^2+5=0 \\ 0|-5(0)^2+5=5 \\ 1|-5(1)^2+5=0 \\ 2|-5(2)^2+5=15 \end{gathered}[/tex]Then the graph passes by the points
[tex]\begin{gathered} (-2,15) \\ (-1,0) \\ (0,5) \\ (1,0) \\ (2,15) \end{gathered}[/tex]From this, you can draw the points in a cartesian plane.
Once we have the graph we can answer the question.
The parabola open down.
the vertex of the parabola is a maximun since all the other points are below it.
Finally, we see that the axis of symmetry is the y axis. Since the left part of the the graph is the reflection of the right part.
the vertex of the parabola is the point (0,5).
the y intercept of the parabola is 5. we see that from the point (0,5).

Find the integer that would represent the change in the amount in the account if Awat deposits $17 into his bank account once each day for four days. Explain the difference between the integer for the withdrawals and the integer for the deposits…
The integer that represents the change in Awat's account is $-68.
The difference between the integers that represents withdrawal and deposits is the integer that represents withdrawals is negative while the integer that represents deposits is positive.
What is the integer that represent withdrawals?In order to determine the total withdrawals in four days, multiply the daily withdrawals by the number of days. Multiplication is the arithmetic operation that is used to determine the product of two or more numbers.
Total withdrawals = daily withdrawal x number of days
$17 x -4 = $-68
When there is a withdrawal, the value of the money in the account would decline. Thus, this would be represented with a negative number. A negative number has a negative sign in front of it. When there is a deposit, the value of the money in the account would increase. Thus, this would be represented with a positive number.

Step-by-step explanation:
Two triangles are said to be similar if their corresponding angles are the same size and the corresponding sides are in the same ratio.
Therefore, if triangle ABC is similar to triangle MNP then their corresponding angles are congruent:
m∠A = m∠Mm∠B = m∠Nm∠C = m∠PSimilarly, if triangle ABC is similar to triangle MNP then their corresponding sides are in the same ratio:

SAS Triangle Similarity
If two sides of one triangle are in the same ratio to the corresponding sides of another triangle, and their included angles are congruent, then the triangles are similar.
∠A is the included angle of sides AB and AC.
∠M is the included angle of sides MN and MP.
Therefore, the only statement that shows that two corresponding sides are in the same ratio and their included angles are congruent is:

Two unique points on a line define the boundaries of a line segment. A line segment is also known as a part of a line that connects two locations. A line and a line segment vary in that a line has no ends and can continue indefinitely in any direction.
We can write as,
IK=IJ+JK
15=13+JK
JK=15-13
JK=2
Therefore, The length of the segment JK is 2.

Carson drove a distance of 120120120 kilometers. He initially had 303030 liters of fuel, and his car's fuel efficiency is 100100100 cubic centimeters per kilometer.
What calculation will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters?
If he initially had 30 liters of fuel, and his car's fuel efficiency is cubic centimeters per kilometer. The calculation will give us the estimated volume of fuel that remains in Carson's tank by the end of the drive, in liters is: 30- 100/1000×120
How to determine the estimated volume?Given data:
Distance = 120 kilometers
Liters of fuel = 30 liters
Using this formula to find the remaining volume
Remaining volume = I - E × D
Where:
I = Initial volume
E = Fuel efficiency
D = Distance
First step is to formula an equation that will be use to find the remaining volume
Equation = 30- 100/1000 ×120
Now let use the formulated equation to find the remaining volume
Remaining volume = 30- 100/1000 × 120
Remaining volume = 30- 12
Remaining volume = 18
Therefore 30- 100/1000×120 can be used to determine the remaining volume.
