Answer:
Step-by-step explanation:
The graph is of the equation y = -x^2 +4. It is a polynomial of even degree, so has a domain of all real numbers: (-∞, ∞).
The vertical extent of the graph includes y=4 and all numbers less than that:
range: (-∞, 4]
The graph is increasing to the left of its vertex at x=0, decreasing to the right.
increasing (-∞, 0); decreasing (0, ∞)
There is no interval on which the function is constant. It has a horizontal tangent at x=0, but a single point does not constitute an interval.
The domain of a function refers to all possible inputs while the range comprises all potential outputs. The function increases, decreases, or remains constant when the respective slope is positive, negative, or zero. I've provided an explanation based on the indication of the respective slopes described in your problem.
To determine the domain, range, and intervals of increase, decrease, or constant for a function, we need to examine the specific input and output values as well as the curvature of the function.
Domain of a function refers to all possible input values (x-values). For example, in the probability distribution function (PDF), the domain may include all numerical values or could be expressed through a non-numerical set such as different hair colors. From the provided information, I can deduce that the domain of X is {English, Mathematics, ...} - a list of all majors offered at the university, indicating all the possible inputs of this function. The domain of Y and Z are numerical, from zero up to an upper limit.
Range of a function is all the potential output values (y-values). The range is usually derived from the domain values after undergoing certain transformations via the function. Unfortunately, without further specifics about the function, I can't provide a conclusive range.
For intervals of increase, decrease, or constant, you look at the slope of the function. A function is increasing on an interval if the y-value increases as the x-value increases. Contrary to this, a function is decreasing on an interval if the y-value decreases as the x-value increases. If the y-value remains constant as the x-value varies, the function is constant on that interval. Different parts of your provided solutions indicate the function starts with positive slope (increasing), then levels off (becomes constant).

the AAS Theorem
Answer: the ASA Postulate
Step-by-step explanation:
In the given picture , we have two triangles ∆LKM and ∆JKM , in which we have
[common]
By using ASA congruence postulate , we have
∆LKM and ∆JKM
ASA congruence postulate tells that if two angles and the included side of a triangle are congruent to two angles and the included side of other triangle then the triangles are congruent.

Step-by-step explanation:
Answer: Robert runs for approximately 1.50 more hours after taking a break.
Step-by-step explanation:
To find out how many more hours Robert runs after taking a break, we need to determine the time it takes for him to run the remaining distance.
We know that Robert runs a total of 25 miles and his average speed is 7.4 miles per hour. To find the time it takes for him to run the entire 25 miles, we can use the formula:
Time = Distance / Speed
Time = 25 miles / 7.4 miles per hour
Time ≈ 3.38 hours
Since Robert takes a break after running 13.9 miles, we need to subtract the time it took him to run that distance from the total time.
To find the time it took him to run 13.9 miles, we can use the formula:
Time = Distance / Speed
Time = 13.9 miles / 7.4 miles per hour
Time ≈ 1.88 hours
Now, we can subtract the time for the break from the total time to find how many more hours Robert runs:
Remaining time = Total time - Time for the break
Remaining time ≈ 3.38 hours - 1.88 hours
Remaining time ≈ 1.50 hours
Therefore, Robert runs for approximately 1.50 more hours after taking a break.
Answer:
1.5 hours more
Step-by-step explanation:
In order to find out how many more hours Robert runs, we need to find the total time it takes him to run 25 miles. We can do this by dividing the total distance by his average speed.
We already know that Robert takes a break after 13.9 miles. This means that he runs for:
And to find out how many hours Robert runs after his break, we need to divide the distance he runs after his break by his average speed.
Therefore, Robert runs for 1.5 hours more after his break.
