D. Based on similar triangles, the relationship established is 7/BD = BD / 18, using triangles ABD and BDC. Solving this yields BD^2 = 126. Maintain this format for clarity before applying rounding later. As triangle BDC is a right triangle, we can utilize the Pythagorean Theorem to find m, leading to m^2 = BD^2 + 7^2, which calculates to m^2 = 175—take the square root to find m = 13.22, confirming that the solution is D.

AnnZ [12381]

The total volume is stated as 1080 cubic feet.

The height is specified to be 9 feet.

The length exceeds the width by 2 feet, meaning Length = x+2

If the stall measures 10 feet in width, then the corresponding length would be 10 +2 = 12 feet.

Calculating the volume yields 10 x 12 x 9 = 1080 cubic feet.


Therefore, it is feasible for the width to measure 10 feet.

Inessa [12570]
The Pythagorean theorem is a foundational principle. Given that 2 and 5 represent the lengths of the legs while c denotes the hypotenuse, the relevant equation would be stated as such, corresponding to the first option.

A neighborhood is trying to set up school carpools, but they need to determine the number of students that need to travel to the
AnnZ [12381]

Answer:

The correct selection is 1.

Step-by-step explanation:

The histogram indicates that

In the 5-10 age group, there are 7 students.

In the 11-13 age group, 5 students are represented.

In the 14-18 age category, 4 students are included.

This implies that the ages of 7 students fall within the 5-10 range, 5 students within the 11-13 range, and 4 students within the 14-18 range.

The total count in the dataset is 7+5+4=16

In options 3 and 4, the counts in the datasets are fewer than 16. Hence, options 3 and 4 are invalid.

Option 2 exclusively contains data within the 5-10 range, making it incorrect as well.

In option 1,

Class intervals      elements           frequency

5-10                    5,6,7,8,9,10,10           7

11-13                  11,11,12,12,13            5

14-18                    14,14,15,16              4

Based on the above table, we can determine that data set 1 is represented in the provided histogram.

Thus, the answer is option 1.

The flight path of a golf ball is modeled by the function, F (X) = -0.0 2X^2 Plus 6X, we are X represents the horizontal distanc
lawyer [12517]
Let’s tackle the problem. We know the formula for <span>the height of the ball is as follows:

</span>f(x)=-0.02x^{2}+6x
<span>
Here, x represents </span><span>the horizontal distance in yards that the ball has traveled in the air. Given that distance is always a positive value, we conclude that x must be greater than or equal to 0. Thus:

</span>x \geq 0<span>

The horizontal plane indicates the function's zero point, and since the ball cannot have negative height values, f(x) must also remain positive. Ultimately, the graph reveals that the suitable domain is:

</span>\boxed{0 \leq x \leq 300}<span>
</span><span>
</span>
