The graph of g(x) is obtained by reflecting the graph of f(x)=4|x| over the x-axis.
Which equation describes g(x)?
g(x)=|x+4|g(x)=|x|−4g(x)=|x−4|g(x)=−4|x|
Answers
Answer:
Option D
Step-by-step explanation:
The given function is
[tex]f(x)=4|x|[/tex]
It is given that the graph of g(x) is obtained by reflecting the graph of f(x)=4|x| over the x-axis.
If a figure reflected across x-axis, then the rule of reflection is
[tex](x,y)\rightarrow (x,-y)[/tex]
Using the above rule, if the given function reflected across x-axis, then g(x)=-f(x).
[tex]g(x)=-(4|x|)[/tex]
[tex]g(x)=-4|x|[/tex]
The equation g(x)=-4|x| describes g(x).
Therefore, the correct option is D.

A single ball is drawn from an urn containing 6 balls numbered 1 through 6. Find the probability that the ball choosen is as follows.
An even-numbered ball or an odd-numbered ball
Answers
Final answer:
The probability of drawing an even-numbered ball or an odd-numbered ball from the urn is 1.
Explanation:
To find the probability of drawing an even-numbered ball or an odd-numbered ball from an urn containing 6 balls numbered 1 through 6, we need to determine the total number of favorable outcomes and divide it by the total number of possible outcomes.
The total number of possible outcomes is 6, as there are 6 balls in the urn.
The favorable outcomes are the even-numbered balls (2, 4, 6) and the odd-numbered balls (1, 3, 5), which is a total of 6 balls.
Therefore, the probability of drawing an even-numbered ball or an odd-numbered ball is 6/6, which simplifies to 1.
A body is moving along a straight line with a velocity which varies according to the equation v = 9 t2 + 2t, where v is in feet per second and t is in seconds. Find the expression for the distance as a function of time. A. 3t3 + 2t2 + C B. 3t3 + t2 + C C. 20t + C D. 18t + C
Answers
To find a function for distance as a function of time:
Using Calculus:
Take the integral of V(t)
This means find the anti-derivative (if v(t) is the derivative of d(t), what must d(t) be?)
d (t) = (1/3)*9* t ²⁺¹ + (1/2) * 2 * t¹⁺¹
d(t) = 3t³ + t² + C
Answer is B) 3t³ + t² + C.
Why did we add C at the end? The velocity function doesn't tell us anything about our initial distance, so we add C to account for wherever we started at t=0. This is also known as our Constant of Integration

So, For compare we can find the percent of that ratios and simply by comparison we get the large and small ratio as;
⇒ 19/25 = 0.76 = 76%
⇒ 17/20 = 0.85 = 85%
Thus, The percent of ratio 17/20 is more than the percent of ratio 19/25.

Is there a number that is exactly 3 more than its cube?
Answers
They are the solutions to (x-x^3=3).
The exact value for the real solution is:
(sqrt(239)/(2*3^(3/2))-3/2)^(1/3)+1/(3*(sqrt(239)/(2*3^(3/2))-3/2)^(1/3))
Approximately, it is x=-1.67169988...
If you are expecting integers (which was not specified), then there is none.
For a given number X, its cube is written as X^3.
Here we want to see if we can find a number that is exactly 3 more than its cube, this means that:
[tex]X = X^3 + 3[/tex]
We will see that yes, there exists a number with this property.
Then we can try to solve this to find the number with that given property.
We can rewrite it as:
[tex]-X^3 + X - 3 = 0[/tex]
Now we can solve this for X, as the question asks about existence and not for the exact number, we can graph this the above function:
[tex]f(X) = -X^3 + X - 3[/tex]
And if it crosses the x-axis, then at some point we have:
[tex]f(X) = 0[/tex]
This would imply that there exists a real number that is 3 more than its cube.
The graph can be seen below, and we can see that it intersects the X-axis, then yes, there is a number that is exactly 3 more than its cube.
And by watching the graph, we can see that the number is:

Which of the following illustrates the truth value of the given conditional statement? If ice is hot, then rain is wet.
F T → T
T T → T

F F → T
Answers
Answer: The correct option is (A) F T → T.
Step-by-step explanation: We are given to select the correct illustration of the truth value of the following conditional statement :
"If ice is hot, then rain is wet".
Let p : Ice is hot. This is a false statement.
And
q : rain is wet. This statement is true.
We know that
The statement "if p then q" is written as p ⇒ q.
Since p is false and q is true, so p ⇒ q will be true.
That is,
p q p ⇒ q
