The area of the triangle, A(x), can be expressed as A(x) = (x * sqrt(3x^2/4))/2 and the height of the triangle, h, can be expressed as h = sqrt(3x^2/4) in terms of the base.
The landowner wishes to use 3 miles of fencing to enclose an isosceles triangular region of as large an area as possible. Let x be the length of the base of the triangle.The length of the base of the triangle is x miles, while the length of the other two equal-length sides are 2x miles each. Thus, the total length of the three sides of the triangle is 3x miles, which equals 3 miles of fencing as required.
To find the area of the triangle, we must first calculate the height of the triangle. Using the Pythagorean Theorem, we can calculate the height of the triangle in terms of the base. The formula is h^2 = (2x)^2 - (x/2)^2. Thus, the height of the triangle, h, can be expressed as h = sqrt(3x^2/4).The area of the triangle is equal to the base multiplied by the height and divided by two. Thus, the area of the triangle, A(x), can be expressed as A(x) = (x * sqrt(3x^2/4))/2.

A truck driver needs to drive 400 miles. The drivers average speed for the first 180 miles is b miles per hour. The drivers average speed for the rest of the trip is c miles per hour. Enter an equation for the total time, t, in hours it took the driver to complete the entire trip
Step-by-step explanation:
speed = distance/time
time = t = distance/speed
t = 180/b + (400-180)/c = 180/b + 220/c = 20(9/b + 11/c)

2) A fair coin was tossed 75 times. The coin landed on Heads 42 times and Tails 33 times. What is the experimental probability of the coin landing tails side up? Your answer needs to be a fraction in simplest form. Grid in boxes below. One digit/symbol per box, 7. SP.6 5) Tanya set a goal to swim 30
Answer:
\(\frac{11}{25}\)
Step-by-step explanation:
In the experiment that was conducted the coin was tossed a total of 75 times and out of those times it only landed on tails 33 times. Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...
\(\frac{33}{75}\) or 0.44
This fraction can also be simplified to its simplest form of \(\frac{11}{25}\) which is obtained by dividing both the numerator and denominator by 3
A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting parabola is (4, 6). What is the vertex of the function defined as g(x) = f(x +2) - 2?
If a quadratic function y = f(x) is plotted on a graph and the vertex of the resulting parabola is (4, 6), the vertex of the function defined as g(x) = f(x +2) - 2 is (2, 4).
How to determine the vertex of the function defined as g(x)?In Mathematics, the translation a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image while the translation a geometric figure or graph downward simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.
In Geometry, the function g(x) = f(x + 2) - 2 simply means shifting a graph of the parent function by 2 units to the left and 2 units down.
In this context, we can reasonably infer and logically deduce that the vertex of the image g(x) is given by;
Vertex = (4 - 2, 6 - 2)
Vertex = (2, 4).

Use the simplex algorithm to find the optimal solution to the following LP (solve manually): maxz= 36x1+30x2−3x3−4x4
s.t. x1+x2−x3≤5
6x1+5x2−x4≤10
∀xi≥0
The maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.
maximize: z = c1x1 + c2x2 + ... + cnxn
subject to
a11x1 + a12x2 + ... + a1nxn ≤ b1
a21x1 + a22x2 + ... + a2nxn ≤ b2
am1x1 + am2x2 + ... + amnxn ≤ bmxi ≥ 0 for all i
In our case,
the given LP is:maximize: z = 36x1 + 30x2 - 3x3 - 4x
subject to:
x1 + x2 - x3 ≤ 5
6x1 + 5x2 - x4 ≤ 10
xi ≥ 0 for all i
We can rewrite the constraints as follows:
x1 + x2 - x3 + x5 = 5 (adding slack variable x5)
6x1 + 5x2 - x4 + x6 = 10 (adding slack variable x6)
Now, we introduce the non-negative variables x7, x8, x9, and x10 for the four decision variables:
x1 = x7
x2 = x8
x3 = x9
x4 = x10
The objective function becomes:
z = 36x7 + 30x8 - 3x9 - 4x10
Now we have the problem in standard form as:
maximize: z = 36x7 + 30x8 - 3x9 - 4x10
subject to:
x7 + x8 - x9 + x5 = 5
6x7 + 5x8 - x10 + x6 = 10
xi ≥ 0 for all i
To apply the simplex algorithm, we initialize the simplex tableau as follows:
| Cj | x5 | x6 | x7 | x8 | x9 | x10 | RHS |
---------------------------------------------------------------------------
z | 0 | 0 | 0 | 36 | 30 | -3 | -4 | 0 |
---------------------------------------------------------------------------
x5| 0 | 1 | 0 | 1 | 1 | -1 | 0 | 5 |
---------------------------------------------------------------------------
x6| 0 | 0 | 1 | 6 | 5 | 0 | -1 | 10 |
---------------------------------------------------------------------------
Now, we can proceed with the simplex algorithm to find the optimal solution. I'll perform the iterations step by step:
Iteration 1:
1. Choose the most negative coefficient in the 'z' row, which is -4.
2. Choose the pivot column as 'x10' (corresponding to the most negative coefficient).
3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.
Ratios: 5/0 = undefined, 10/(-4) = -2.5
4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.
5. Perform row operations to
make all other elements in the pivot column zero.
After performing these steps, we get the updated simplex tableau:
| Cj | x5 | x6 | x7 | x8 | x9 | x10 | RHS |
---------------------------------------------------------------------------
z | 0 | 0 | 0.4 | 36 | 30 | -3 | 0 | 12 |
---------------------------------------------------------------------------
x5| 0 | 1 | -0.2 | 1 | 1 | -1 | 0 | 5 |
---------------------------------------------------------------------------
x10| 0 | 0 | 0.2 | 1.2 | 1 | 0 | 1 | 2.5 |
---------------------------------------------------------------------------
Iteration 2:
1. Choose the most negative coefficient in the 'z' row, which is -3.
2. Choose the pivot column as 'x9' (corresponding to the most negative coefficient).
3. Calculate the ratios (RHS / pivot column coefficient) to find the pivot row. We select the row with the smallest non-negative ratio.
Ratios: 12/(-3) = -4, 5/(-0.2) = -25, 2.5/0.2 = 12.5
4. Pivot at the intersection of the pivot row and column. Divide the pivot row by the pivot element to make the pivot element 1.
5. Perform row operations to make all other elements in the pivot column zero.
After performing these steps, we get the updated simplex tableau:
| Cj | x5 | x6 | x7 | x8 | x9 | x10 | RHS |
---------------------------------------------------------------------------
z | 0 | 0 | 0.8 | 34 | 30 | 0 | 4 | 0 |
---------------------------------------------------------------------------
x5| 0 | 1 | -0.4 | 0.6 | 1 | 5 | -2 | 10 |
---------------------------------------------------------------------------
x9| 0 | 0 | 1 | 6 | 5 | 0 | -5 | 12.5 |
---------------------------------------------------------------------------
Iteration 3:
No negative coefficients in the 'z' row, so the optimal solution has been reached.The optimal solution is:
z = 0
x1 = x7 = 0
x2 = x8 = 10
x3 = x9 = 0
x4 = x10 = 0
x5 = 10
x6 = 0
Therefore, the maximum value of z is 0, and the values of the decision variables are x1 = 0, x2 = 10, x3 = 0, x4 = 0.

For the position function s(t) = 3t2 - 2t + 1, where "t" is measured in minutes and "s(t)" is measured in feet, use the Limit Definition of the Derivative to find each of the following (and be sure to include appropriate units in your final answers):a) Velocity, which is s'(t). b) Acceleration, which is dt2
The velocity function is s'(t) = 6t - 2, and the units are feet per minute. The acceleration function is s''(t) = 6, and the units are feet per minute squared.
a) To find the velocity, which is the derivative of the position function with respect to time, we need to use the limit definition of the derivative:
s'(t) = lim(h→0) [s(t+h) - s(t)] / h
= lim(h→0) [(3(t+h)2 - 2(t+h) + 1) - (3t2 - 2t + 1)] / h
= lim(h→0) [3t2 + 6th + 3h2 - 2t - 2h + 1 - 3t2 + 2t - 1] / h
= lim(h→0) [6th + 3h2 - 2h] / h
= lim(h→0) [6t + 3h - 2]
= 6t - 2
b) To find the acceleration, which is the derivative of the velocity function with respect to time, we need to take the derivative of the velocity function:

If angle W measures 35º, what are the measures of the other angles in the diagram? Use your knowledge of supplementary angles to complete
the table.
The measure of angles are ∠S = 35°, ∠T = 145°, ∠U = 35°, ∠V = 145°, ∠W = 35°, ∠X = 145°, ∠Y = 35° and ∠Z = 145°.
Transversal Angles:When a transversal splits two parallel lines, the two intersections create a number of angles as given in the picture.
When the angles are formed by a transversal the corresponding angles are equal in measure. Similarly, the angles which are vertically opposite are also equal in measure
Here we have
A transverse cuts two parallel lines
Given that the measure of ∠W = 35°
Here ∠W = ∠ Y [ ∵ vertically opposite angles ]
=> The measure of ∠Y = 35°
From the straight line,
∠W + ∠Z = 180° [ pair of linear angles ]
=> 35° + ∠Z = 180°
=> ∠Z = 180° - 35°
=> ∠Z = 145°
Here measure of ∠Z = measure of ∠X [ ∵ vertically opposite angles ]
=> Measure of ∠X = 145°
Since the given lines are parallel lines
=> ∠W = ∠S = 35° [ ∵ corresponding angles ]
=> ∠U = ∠W = 35° [ ∵ vertically opposite angles ]
=> ∠T = ∠X = 145° [ ∵ corresponding angles ]
=> ∠X = ∠V = 145° [ ∵ vertically opposite angles ]
Therefore,
The measure of angles are ∠S = 35°, ∠T = 145°, ∠U = 35°, ∠V = 145°, ∠W = 35°, ∠X = 145°, ∠Y = 35° and ∠Z = 145°.

Is the relation shown in the arrow diagram a function? Justify your answer.
Answer:
NO
Step-by-step explanation:
For a relation to be a function, every input (x-value) must have exactly one output (y-value) mapped to it or related to it.
This means, in a function, an input value cannot give you two different outputs.
Therefore, relation shown in the arrow diagram IS NOT A FUNCTION, because one of the inputs (x-value), which is 1.2, has two different outputs (y-value) that is mapped or related to it, which are 6 and 8.

The demand function for the shirts of a concert-promoting company which has been selling an average of 175 T-shirts at performances for $23 each is y=175-6.08x.
What is demand function?The demand function is the function
\(Q=a-bP\)
Here, Q is linear demand curve, a factor which influence the demand, b is slope and P is price.
A concert-promoting company has been selling an average of 175 T-shirts at performances for $23 each. Thus, the total selling price is,
\(P=175\times23\\P=4025\)

Michael drove from home to work at an average speed of 45 mph. His return trip home took 45 minutes longer because he could only drive at 35 mph. Find the distance from his home to his work.
The distance from his home to his work place is 118.125 miles
How to find the distance from his home to his work place?He drove from home to work at an average speed of 45 mph. Therefore,
speed = 45 mph
let
time = x
speed = distance / time
distance = 45x
His return trip home took 45 minutes longer because he could only drive at 35 mph. Therefore,
45 minutes = 0.75 hours
distance = 35(x + 0.75)
distance = 35x + 26.25
Therefore,
45x = 35x + 26.25
45x - 35x = 26.25
10x = 26.25

PLZZZZZ HELP ASAP
Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.
