A bucket has a leak that started 6 hours ago. At time 0, when the bucket just emptied, a tap was turned on for 3 hours. The amount of water in the bucket can be modeled by the function f(x) = |x| over the interval [−6, 3], where x is the time, in hours, and y is the amount of water in the bucket, in gallons. Which translation of the graph represents the last 3 hours of the leak, and the tap running for 6 hours? Group of answer choices g(x) = |x − 3| g(x) = |x| + 3 g(x) = |x| − 3 g(x) = |x + 3|
Answers
Answer:
The answer is g(x) = |x - 3|
Step-by-step explanation:
Here we have a general problem of horizontal translations, we will see that the correct option is g(x) = |x - 3|
We know that the bucket was leaking for 6 hours, and then it was filled in 3 hours.
Then in the interval [-6, 0) the bucket was leaking
In the interval [0, 3] the bucket was being filled.
Now we want a transformation that represents the last 3 hours of leaking.
Also, remember that for a general function f(x), an horizontal translation of N units is written as:
g(x) = f(x + N)
If N is positive, the translation is to the left
If N is negative, the translation is to the right.
If we want to represent the last 3 hours of leaking (which happen for negative values of x) then we need to move the whole graph to the right.
So, if we define the function as:
g(x) = f(x - 3)
when we evaluate g(x) in zero we get:
g(0) = f(-3)
So this new function, at the time zero, starts representing the last 3 hours of leaking of the bucket.
Remembering that f(x) = |x|
We can see that the correct option is:
g(x) = f(x - 3) = |x - 3|
g(x) = |x - 3|
Below you can see a graph with a comparison of f(x) and g(x), where the green one is f(x) and the blue one g(x).

Answers
Answer:
sine and cosec are inverse of each other.
cosine and sec are inverse of each other.
tan and cot are inverse of each other.
Step-by-step explanation:
Given point on terminal side of an angle ([tex]\frac{1}{3},\frac{1}4[/tex]).
Kindly refer to the attached image for the diagram of the given point.
Let it be point A([tex]\frac{1}{3},\frac{1}4[/tex])
Let O be the origin i.e. (0,0)
Point B will be ([tex]\frac{1}{3},0[/tex])
Now, let us consider the right angled triangle [tex]\triangle OBA[/tex]:
Sides:
[tex]Base, OB = \frac{1}{3}\\Perpendicular, AB = \frac{1}{4}[/tex]
Using Pythagorean theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow OA^{2} = OB^{2} + AB^{2}\\\Rightarrow OA^{2} = \frac{1}{3}^{2} + \frac{1}{4}^{2}\\\Rightarrow OA = \sqrt{\frac{1}{3}^{2} + \frac{1}{4}^{2}}\\\Rightarrow OA = \sqrt{\frac{4^2+3^2}{3^{2}.4^2 }}\\\Rightarrow OA = \frac{5}{12}[/tex]
[tex]sin \angle AOB = \dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\Rightarrow sin \angle AOB = \dfrac{\frac{1}{4}}{\frac{5}{12}}\\\Rightarrow sin \angle AOB = \dfrac{3}{5}[/tex]
[tex]cos\angle AOB = \dfrac{Base}{Hypotenuse}[/tex]
[tex]\Rightarrow cos \angle AOB = \dfrac{\frac{1}{3}}{\frac{5}{12}}\\\Rightarrow cos\angle AOB = \dfrac{4}{5}[/tex]
[tex]tan\angle AOB = \dfrac{Perpendicular}{Base}[/tex]
[tex]\Rightarrow tan\angle AOB = \dfrac{3}{4}[/tex]
[tex]cosec \angle AOB = \dfrac{Hypotenuse}{Perpendicular}[/tex]
[tex]\Rightarrow cosec\angle AOB = \dfrac{5}{3}[/tex]
[tex]sec\angle AOB = \dfrac{Hypotenuse}{Base}[/tex]
[tex]\Rightarrow sec\angle AOB = \dfrac{5}{4}[/tex]
[tex]cot\angle AOB = \dfrac{Base}{Perpendicular}[/tex]
[tex]\Rightarrow cot\angle AOB = \dfrac{4}{3}[/tex]

Answers
Answer:
Option C. y = ( c + b ) / a
Step-by-step explanation:
For this problem, we must simply isolate the y variable from the unknowns a, b, and c.
ay - b = c
ay - b + b = c + b
ay = c + b
ay * ( 1 / a ) = ( c + b ) * ( 1 / a)
y = ( c + b ) * ( 1 / a )
y = ( c + b ) / a
Thus, we will want to choose option C.

The Roberts family is taking a road trip. They plan to drive 1500 miles over two days, stopping for the night when they are halfway. How many hours will they drive for the first day if they average 50 mph over the course of the trip?
Explain:
Answer:
Answers
Answer:
The number of hours they would have to drive for the first day if they average 50 mph over the course of the is 15 hours
Step-by-step explanation:
The given parameters are;
The distance the Roberts family plan to drive = 1500 miles
The average speed at which they drove = 50 mph
We note that the formula for average speed = Total distance/(time)
Therefore, we have;
50 mph = 1500 miles/(time, t)
Time = 1500 miles/(50 mph) = 30 hours
Given that for the first day of the 2 days, they will cover half their total distance, which is 1500 m/2 = 750 m
The time taken = 750 miles/(50 mph) = 15 hours
The time take to cover half the distance = 15 hours
Therefore, the number of hours they would have to drive for the first day if they average 50 mph over the course of the is 15 hours.

solve this question please: x² = -169
Answers
Answer:
13i, -13i
Step-by-step explanation:
To solve this equation, we need to take the square root of both sides. The square root of 169 can be either 13 or -13, but this time, they asked for -169. Whenever we take the square root of a negative number, we put the letter i, which stands for imaginary. It is never capitalized, so we remove the negative sign from -169, and take the square root of that. We get -13 and 13 as our answers, and we multiply both numbers by i to get -13i and 13i. Any solutions with i in it are considered complex solutions
