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>

Zina [12379]
<span>The outcome = probability of choosing exactly 2, 3, 4, or 5 passing plays. The probability of selecting exactly two passing plays is given by: (8C2)*(9*8)* (15*14*13*12*11*10) /(26*28*.....19) where: 8C2 represents the combinations of choosing two from 8 and probability that the first passing play is selected = 9/26 probability that the second passing play is chosen = 10/25, and so forth you can similarly calculate the other three scenarios and sum them to find the total probability.</span>

A CD has a 5% chance of being a smash hit and profiting $5.2 million, a 50% chance of being a modest success and profiting $0.9
Zina [12379]

P(S) = Probability of Smash = 0.05 (5%)
P(M) = Probability of Modest = 0.5 (50%)
P(F) = Probability of Flop = 0.45 (45%)
Based on this, we utilize the model for discrete random variables, leading to:
E(X) = (0.05 * 5.2) + (0.5 * 0.9) + (0.45 * 0)
= 0.26 + 0.45 + 0
= 0.71 Mill'

lawyer [12517]
The formula for determining the number of ways to select two pairs of sneakers from three pairs labeled A, B, and C is represented by 3C2 (3 combinations of 2), which calculates as 3! / (2!(3 - 2)!) = 3! / (2! x 1!) = (3 x 2) / (2 x 1) = 3. Therefore, the sample space is S = {AB, AC, BC}.

A flat circular plate has the shape of the region x2 + y2≤1. The plate, including the boundary where x2 + y2 = 1, is heated such
Leona [12618]
Setting both partial derivatives to zero results in a single critical point at (x,y)=\left(\dfrac12,0\right), located within the unit disk.

At this given point, the derivative value of the Hessian matrix is

|H|=\begin{vmatrix}T_{xx}&T_{xy}\\T_{yx}&T_{yy}\end{vmatrix}=\begin{vmatrix}2&0\\0&4\end{vmatrix}=8>0

and the second-order partial derivative with respect to x yields

T_{xx}\bigg|_{(x,y)=(1/2,0)}=2>0

This suggests that the critical point represents a local minimum, marking it as the coldest area on the plate with a temperature of T\left(\dfrac12,0\right)=-\dfrac14.

To find the hottest area on the plate, it must be located along the boundary. Let x=\cos\theta and y=\sin\theta, so that

T(x,y)=T(\theta)=\cos^2\theta+2\sin^2\theta-\cos\theta
T(\theta)=\dfrac32-\cos\theta-\dfrac12\cos2\theta

Thus, the plate's boundary (the circle x^2+y^2=1) is treated as a single variable function \theta examined over \theta\in[0,2\pi). A single differentiation gives

T'(\theta)=\sin\theta+\sin2\theta=0
\implies\theta=0,\theta=\dfrac{2\pi}3,\theta=\pi,\theta=\dfrac{4\pi}3

You will discover that T(\theta) achieves three extrema on the interval (0,2\pi), with relative maxima occurring at \theta=\dfrac{2\pi}3 and \theta=\dfrac{4\pi}3, and a relative minimum at \theta=\pi (and \theta=0, if you wish to include that).

Our minimum has already been identified inside the plate - which you can check to have a lower temperature than at the points noted by T(\theta) - and we identify two maxima at \theta=\dfrac{2\pi}3 and \theta=\dfrac{4\pi}3, both showing a maximum temperature of T=\dfrac94.

Reverting to Cartesian coordinates, these points match up with \left(-\dfrac12,\pm\dfrac{\sqrt3}2\right).
