Answer:

The interval of decrease is 0 ≤ x ≤ 1.25

Step-by-step explanation:

First, we have to find the point where it changes from increasing to decreasing or decreasing to increasing.

The graph shows that there is a decrease before 1.25 h, and it increases after 1.25 h also.

We can further prove that 1.25 is the point of change when we enter 1.25 in place of t in the given equation

d(1.25) = 40|1.25 - 1.25| = 0

We see that the graph is decreasing before 1.25, so the interval will have to end at 1.25.

We also see that there is no increase before 1.25, so we can make the interval begin at 0

NEED MATH HELP QUICK!

Korolek [52]

Answer:

Minimum = 14

$Q_1=23$

Median = 32

$Q_3=49$

Maximum = 65

Step-by-step explanation:

Step 1: Put your numbers in ascending order (from smallest to largest). For this particular data set, the order is

14, 18, 28, 29, 32, 44, 48, 50, 65

Step 2: Find the minimum and maximum for your data set. Now that your numbers are in order, this should be easy to spot.

Minimum = 14

Maximum = 65

Step 3: Find the median. The median is the middle number. The middle number in your list is 32, so

Median = 32

Step 4: Place parentheses around the numbers above and below the median.

(14, 18, 28, 29), 32, (44, 48, 50, 65)

Step 5: Find Q1 and Q3. Q1 can be thought of as a median in the lower half of the data, and Q3 can be thought of as a median for the upper half of data.

First quartile

$\bf{Q_1=\dfrac{18+28}{2}=\dfrac{46}{2}=23}$

Third quartile

$\bf{Q_3=\dfrac{48+50}{2}=\dfrac{98}{2}=49}$

Step 6: Write down your summary found in the above steps.

Minimum = 14

$Q_1=23$

Median = 32

$Q_3=49$

Maximum = 65

Fuzzy draws a segment of positive length in a plane. How many locations can Fuzzy place another point in the same plane to form

Mars2501 [29]

Answer: 2 locations.

Step-by-step explanation:

This segment will be the hypotenuse, now, if we find the exact middle of this segment and we draw a line that cuts perpendicularly the segment by the middle, then we can put a point in any point of that line (except in the segment because this will make a degenerate triangle). Then we connect both extremes of the segment with that point, and for how we find it, we know that these new lines will have the same lenght, so this will be an isosceles triangle.

Now, if we want that the triangle is also a right triangle, then the angle between the new sides must be 90°, if we put the point near the segment, the angle will be larger than 90°, and if we put it really far away, the angle will be smaller than 90°. So for each side of this line, we have only one point where the angle is exactly 90°.

this means that we have 2 locations that can create a non-degenerate isosceles right triangle.
