The y-intercept of a function is the value of y = -9 when x = 0. Therefore, the functions have the same y-intercept.

How to find y-intercept?

A function's y-intercept is the value of y at x = 0. It is, in other words, the location of the graph's intersection with the y-axis.

the point on a line, curve, or surface where the y-axis touches that point.

Therefore,

Function 1:

r = 5 / 8 t - 9

r = 5 / 8 (0) - 9

r = -9

hence, the y-intercept is -9

Function 2:

when t = 0, r = -9

Hence, the value of  y-intercept is -9

Answer:

Greek mathematician Heron of Alexandria was the first to determine the area of a triangle with three sides. Instead of using the triangle's side lengths, he provided a method that could compute a triangle's area without the need to measure any angles or other distances.

Let ABC be a triangle with lengths AB = c, BC = a, and CA = b for each of its three sides.

Triangle ABC's semi-perimeter is equal to s = (a + b + c)/2.

When the lengths of a triangle's three sides are known, the area of the triangle may be calculated using Heron's formula. To use this method, we must first determine the triangle's perimeter, which is the total distance around the triangle and is determined by summing the lengths of its three sides. There are two crucial phases in Heron's formula.

The semi perimeter of the triangle = 7 + 25 + 24 = 28 cm

According to the response to the question, the trigonometric ratios will be tan Y = 8/15, tan X = 15/8, and sin Y = 8/17.

Trigonometric functions, which are real functions, are used in mathematics to connect the angle of a right - angled triangle to the proportion of the lengths of its two sides. They are widely utilized in a variety of fields connected to geometry, including celestial mechanics, solid mechanics, and geodesy. Trigonometric ratios are all trigonometric values based on the values of the right triangle's aspect ratio. The trigonometric ratio of the opposite sides of a right triangle reduced by any extreme angle is one.

Here,

Because X is actually 8/17,

the right response to this question is not X.

TanX = 15/8 = Opp

Sin x = 8/17 is accurate.

2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension. This third dimension allows for rotation and visualization from multiple perspectives.

2D transforms happen only on 2 or sometimes even 1 axis. For example if you are in a top orthographic view and rotate an object clockwise, you are usually only changing its rotation value in one axis (z axis in Blender, y in some other software).

In a perspective view, if you are able to use a gizmo to manipulate multiple axis you may be changing the rotation value on all three axes, this would be a 3D transformation.

You can shift an object on any of the three axis easily by grabbing the arrow and sliding the object, or you can move it to an entirely new set of coordinates, that's a 3D transformation.

A = Pe^(rt)

where A is the final account balance, P is the initial principal (or starting) amount, r is the interest rate, and t is the time (in years) for which the interest is being calculated.

Substituting in the given values:

1,433,785.18 = P * e^(0.054 * 12)

To find P, we can divide both sides by e^(0.054 * 12)

P = 1,433,785.18 / e^(0.054 * 12)

(B) If a technical breakthrough occurred that raised the profit per unit of X to $8, would this affect the optimal solution is, = 10.625

(C) Instead of an increase in the profit coefficient X to $ 8, suppose that profit was overestimated and should only have been $ 3 is, = 10.625

Given that,

The following LP problem:

Maximize profit = 5X + 6Y

Subject to 2X+Y= 120

2X+ 3Y = 240

X,Y= 0

Maximize C = 5X + 6Y

2X+Y= 120

2X+ 3Y = 240

and x = 0, y = 0

Plot the lines on graph,

2X+Y= 120

2X+ 3Y = 240

x = 0, y = 0

So, boundary points of feasible region are (0,1.7) , (2.125,0) and (0,0)

Substitute the points in  Maximize C

At  (0,1.7)

Maximize C = 5X + 6Y

C = 5(0) + 6(1.7)

C = 0 + 10.2

Maximize C = 10.2

At  (2.125,0)

Maximize C = 5(2.125) + 6(0)

Maximize C = 10.625

At   (0,0)

Maximize C = 5(0) + 6(0)

Maximize C = 0

So, Maximum value is attained at   (2.125,0)

So, the optimal value of x is 2.125

The optimal value of y is 0

The maximum value of the objective function is 10.625

There are several ways to calculate optimal solution; one of them, is by using graphs.

The optimal value of x is 2.125

The optimal value of y is: 0

The maximum value of the objective function is: 10.625

Therefore,

(A) The optimal solution to this problem = 2.125
