which term best describes the number of solutions that will maximize the function below given the constraints listed? (assume that and .) 3x 2y a. one optimal solution c. unbounded b. alternate optimal solutions d. infeasible please select the best answer from the choices provided a b c d
Final answer:
The best term that describes the number of solutions that will maximize the function is one optimal solution (a)
What exactly do you mean by a practical solution ?
A practicable solution is one that complies with all limitations and specifications. When all of the requirements and constraints cannot be satisfied by any combination of decision variable values, a solution is deemed to be infeasible. The parabola's highest or lowest point represents the ideal value. If only the parabola expands down words, the optimal value, also known as the vertex of the parabola, would be maximal. The minimal value is one opening upwards. The vertex's "Y" coordinate is it.
An option for making a judgment or a resolution that does not adhere to one or more constraints. The corners of the entire model's graph would contain the ideal answer.
Explanation:
(Assume that [tex]x > 0[/tex] and [tex]y > 0[/tex].)
[tex]x + 2 < 5x-y < 2[/tex]
[tex]F(x,y) = 2x+y[/tex]
So , the equation becomes a optimal solution.

For item a, we want a non-linear function, which has a highest exponent different of 1, that does not go through the origin, hence the function can be:
f(x) = x² + 3.
For item b, we also want a non-linear function with a radical, hence the function can be:
[tex]g(x) = \sqrt{x}[/tex].
For item c, the composite function is:
[tex]f(g(x)) = f(\sqrt{x}) = (\sqrt{x})^2 + 3 = x + 3[/tex]
For item d, the composite function is:
[tex]g(f(x)) = g(x^2 + 3) = \sqrt{x^2 + 3}[/tex]

A ship sails 300 km west and then 500 km south. How far, to the nearest km, is the ship now from its starting position?
Step-by-step explanation:
this creates a right-angled triangle, with the pure coordinate changes being the legs, and the actual distance being the Hypotenuse (the side opposite of the 90° angle).
and so, we can use Pythagoras :
distance² = leg1² + leg2² = 300² + 500² =
= 90000 + 250000 = 340000
distance = sqrt(340000) = sqrt(10000×34) = 100×sqrt(34) =

The slope-intercept form of the equation of the line described is y = -6x/5 + 32/5.
Given the following data:
Points on x-axis = (-12, 6).
Points on y-axis = (14, -1).
What is a slope?A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
How to calculate the slope of a line?Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given points into the formula, we have;
Slope = (6 + 12)/-1 - 14)
Slope = -18/15
Slope = -6/5
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
x and y are the points.m represents the slope.c represents the intercept.At point (-12, 14), we have:
14 = -6/5(-12) + c
8 = 72/5 + c
40 = 72 + 5c
5c = 72 - 40
c = 32/5
In conclusion, we can reasonably and logically deduce that the slope-intercept form of the equation of the line described is y = -6x/5 + 32/5.

1. The elevation is -15,976 feet
2. The elevation is 15,976 feet
3. A good expression would be -18,492 + 2,516
4. The elevation is 21,008 feet
5. The elevation is -21,008 feet
6. A good expression would be 18,492 + 2,516
7. A good expression would be 18,492 + -2,516
8. A good expression would be -18,492 + -2,516
The correct options are:
The elevation is 15,976 feet
A good expression would be 18,492 + -2,516
What is the elevation?When a person goes up a mountain, the sign used to represent their height above sea level is a positive sign (+). When a person goes down a mountain, the sign used to represent their height above sea level is a negative sign (-). So, the sign in front of 18,492 would be positive and the sign in front of 2516 would be negative.

1/[tex]\sqrt{3}[/tex] is the exact trigonometric ratios for the angle x whose radian measure is given.
What are trigonometric ratios?Sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant are the six trigonometric ratios (sec). A branch of mathematics called trigonometry in geometry deals with the sides and angles of a right-angled triangle. Trig ratios are therefore assessed in relation to sides and angles.
Trigonometric ratios, which contain the values of all trigonometric functions, are based on the ratio of sides of a right-angled triangle. The ratios of a right-angled triangle's sides with regard to a certain acute angle are known as its trigonometric ratios.
The right triangle's three sides are as follows:
Hypotenuse (the longest side)Perpendicular (opposite side to the angle)Base (Adjacent side to the angle)sin(4π/3) = sin(π + π/3)
= - sin(π/3)
= - [tex]\sqrt{3}[/tex]/2
CSC(4π )/3) = csc(π + π /3)
= - csc(π /3)
= - 2/[tex]\sqrt{3\\[/tex]
cos(4π /3) = cos(π + π /3)
= - cos(π /3) = - 1/2
sec(4 π /3) = sec(π + π/3)
= - sec(π /3) = - 2
tan(4π )/3) = tan(π + π /3)
= tan(π/3) = [tex]\sqrt{3}[/tex]

The holy proportion, the golden ratio, and the golden mean are some additional names for this proportion. Then why is this number so important? The fact that so many items in nature have dimensions characteristics that conform to the 1.618 ratio suggests that it plays a fundamental role for the components of nature.

Confidence intervals for can be created using a variety of methods, including the Wald method, precise inference, a variance stabilizing transformation, and many others. Actual and nominal coverage can differ significantly when n is small. For a Poisson mean, we compare nine confidence intervals in terms of coverage and expected width of the confidence bounds. We demonstrate that, for small n, only the exact interval maintains coverage probabilities; the scores interval maintains coverage probabilities roughly, but its expected width is greater than that of the exact interval.A modified confidence interval based on the variance stabilized confidence interval has coverage properties close to the nominal and an expected width that is not particularly large. Therefore, we advise using the exact interval for researchers who want real coverage that is at least nominal and a modified version of the variance stabilized interval for those who are OK with approximative coverage.
