The measure of the angle opposite the longer diagonal of a parallelogram with sides 25.9 cm and 32.5 cm and a longer diagonal of 57.8 cm is 58.63 degrees.
Using the Law of Cosines, we can find the angle opposite the longer diagonal:
cos(A) = (b² + c² - a²) / 2bc
where A is the angle opposite the longer diagonal, b and c are the lengths of the sides adjacent to the angle, and a is the length of the longer diagonal.
In this case, b = 25.9 cm, c = 32.5 cm, and a = 57.8 cm.
cos(A) = (25.9² + 32.5² - 57.8²) / (2 × 25.9 × 32.5) ≈ -0.3765
Since -1 ≤ cos(A) ≤ 1, this value is outside the valid range and there is no solution for A.

( 3 pts.) Maximize Z=$10X+$50Y subject to: (1)3X+4Y≤12 and (2)2X+5Y≤10 03. What combination of X and Y will provide a minimum for this problem? (3pts.) Minimize Z=X+5Y subject to: (1) 4X+3Y≥12 and (2) 2X+5Y≥10
1. The simultaneous solution of the given equations is X=12/5 and Y=4/5
2.1)The combination of X and Y that will yield the optimum for this problem is X=0 and Y=3.3.
2)The combination of X and Y that will provide a minimum for this problem is X=3 and Y=0.
To find the simultaneous solution of the given equations 4X+3Y=12 and 2X+4Y=8, we can use the method of elimination, also known as the addition method. Multiplying the second equation by 2, we get 4X+8Y=16.
Now, we can subtract the first equation from the second equation: 4X+8Y - (4X+3Y) = 8Y - 3Y = 5Y and 16 - 12 = 4. Thus, 5Y=4 or Y = 4/5.
Substituting this value of Y in any of the two equations, we can find the value of X. Let's substitute this value of Y in the first equation: 4X+3(4/5)=12 or 4X
= 12 - (12/5)
= (60-12)/5
= 48/5.
Thus, X = 12/5. Hence, the simultaneous solution of the given equations is X=12/5 and Y=4/5.2. To find the optimal values of X and Y that will maximize the objective function Z=$10X+$50Y, we need to use the method of linear programming.
First, let's plot the feasible region defined by the given constraints:We can see that the feasible region is bounded by the lines 3X+4Y=12, 2X+5Y=10, X=0, and Y=0.
To find the optimal solution, we need to evaluate the objective function at each of the corner points of the feasible region, and choose the one that gives the maximum value.
Let's denote the corner points as A, B, C, and D, as shown above. The coordinates of these points are: A=(0,3), B=(2,1), C=(5/2,0), and D=(0,0). Now, let's evaluate the objective function Z=$10X+$50Y at each of these points:
Z(A)=$10(0)+$50(3)
=$150, Z(B)
=$10(2)+$50(1)
=$70, Z(C)
=$10(5/2)+$50(0)
=$25, Z(D)
=$10(0)+$50(0)=0.
Thus, we can see that the maximum value of Z is obtained at point A, where X=0 and Y=3. Therefore, the combination of X and Y that will yield the optimum for this problem is X=0 and Y=3.3.
To find the combination of X and Y that will provide a minimum for the problem Minimize Z=X+5Y subject to: 4X+3Y≥12 and 2X+5Y≥10, we need to use the same method of linear programming as above.
First, let's plot the feasible region defined by the given constraints:We can see that the feasible region is bounded by the lines 4X+3Y=12, 2X+5Y=10, X=0, and Y=0.
To find the optimal solution, we need to evaluate the objective function Z=X+5Y at each of the corner points of the feasible region, and choose the one that gives the minimum value.
Let's denote the corner points as A, B, C, and D, as shown above.
The coordinates of these points are: A=(3,0), B=(5,1), C=(0,4), and D=(0,0).
Now, let's evaluate the objective function Z=X+5Y at each of these points:
Z(A)=3+5(0)=3,
Z(B)=5+5(1)=10,
Z(C)=0+5(4)=20,
Z(D)=0+5(0)=0.
Thus, we can see that the minimum value of Z is obtained at point A, where X=3 and Y=0. Therefore, the combination of X and Y that will provide a minimum for this problem is X=3 and Y=0.

let f : a → b and g : b → c be functions. prove the following statements. (a) if g ◦ f is injective then f is injective. (b) if g ◦ f is surjective then g is surjective
(a) The equilibrium point is approximately (26, 26) where quantity (x) and price (P) are both 26.
(b) Consumer surplus ≈ 434
(c) 434 dotars (d) -1155 dotars.
To calculate the deadweight loss, we need to find the area between the supply and demand curves from the equilibrium quantity to the quantity \(x_C\).
To find the equilibrium point, we need to set the demand and supply functions equal to each other and solve for the quantity.
Demand function: D(x) = 61 - x
Supply function: S(x) = 22 + 0.5x
Setting D(x) equal to S(x):
61 - x = 22 + 0.5x
Simplifying the equation:
1.5x = 39
x = 39 / 1.5
x ≈ 26
(a) The equilibrium point is approximately (26, 26) where quantity (x) and price (P) are both 26.
To find the point (\(x_C\), \(P_C\)) where the price ceiling is enforced, we substitute the given price ceiling value into the demand function:
P_C = $30
D(\(x_C\)) = 61 - \(x_C\)
Setting D(\(x_C\)) equal to \(P_C\):
61 - \(x_C\) = 30
Solving for \(x_C\):
\(x_C\) = 61 - 30
\(x_C\) = 31
(b) The point (\(x_C\), \(P_C\)) is (31, $30).
To calculate the new consumer surplus, we need to integrate the area under the demand curve up to the quantity \(x_C\) and subtract the area of the triangle formed by the price ceiling.
Consumer surplus
\(=\int[0,x_C] D(x) dx - (P_C - D(x_C)) * x_C\\=\int [0,x_C] (61 - x) dx - (30 - (61 - x_C)) * x_C\\=\int [0,31] (61 - x) dx - (30 - 31) * 31[61x - (x^2/2)]\)
evaluated from
0 to 31 - 31[(61*31 - (31²/2)) - (61*0 - (0²/2))] - 31[1891 - (961/2)] - 311891 - 961/2 - 311891 - 961/2 - 62/2(1891 - 961 - 62) / 2868/2
Consumer surplus ≈ 434
(c) The new consumer surplus is approximately 434 dotars.
To calculate the new producer surplus, we need to integrate the area above the supply curve up to the quantity \(x_C\).
Producer surplus \(= (P_C - S(x_C)) * x_C - \int[0,x_C] S(x) dx(30 - (22 + 0.5x_C)) * x_C - \int[0,31] (22 + 0.5x) dx(30 - (22 + 0.5*31)) * 31 - [(22x + (0.5x^2/2))]\)
evaluated from 0 to 31(30 - 37.5) * 31 - [(22*31 + (0.5*31²/2)) - (22*0 + (0.5*0²/2))](-7.5) * 31 - [682 + 240.5 - 0](-232.5) - (682 + 240.5)(-232.5) - 922.5-1155
(d) The new producer surplus is -1155 dotars. (This implies a loss for producers due to the price ceiling.)

The water capacity of a tank is 1500 liters. In three hours, half of it is being discharged. Find the volume left after 4 hours of discharging. a. 1,000 liters b. 800 liters c. 500 liters
After 4 hours of discharging, the volume left in the tank would be 500 liters. The correct option is C.
Initially, the tank has a water capacity of 1500 liters.
After three hours of discharging, half of the water is discharged, which means 1500/2 = 750 liters have been removed from the tank.
To find the volume left after 4 hours of discharging, we need to subtract the additional amount discharged in the fourth hour.
Since the discharge rate remains the same, we can calculate the amount discharged in one hour as 750/3 = 250 liters.
Therefore, in the fourth hour, 250 liters would be discharged. Subtracting this from the remaining water after three hours (750 liters), we get 750 - 250 = 500 liters.
Therefore, the correct answer is c. 500 liters.

Determine the geometric mean of 11 and 8.
Answer:
\(\sqrt{88}\)
Step-by-step explanation:
The geometric mean of 11 and 8 is equal to \(\sqrt{88}\).
According to the question it is clear that we have to calculate the geometric mean of two positive numbers 11 and 8.
The geometric mean of two positive numbers a and c is the positive number b in such a way that it satisfies the condition
\(\frac{a}{b}=\frac{b}{c}\)
The geometric mean of a and b is √ab if a and b are both positive numbers and it will be −√ab if a and b are negative numbers.
The geometric mean is the positive square root of the product of two numbers.
For a square the geometric mean of two numbers a and b, is the length of one side of a square whose area is equal to the area of a rectangle with the sides of a and b lengths.
If we talk about the n numbers then the geometric mean is the nth root of the product of n numbers. If n positive values are given then the geometric mean is the nth positive root of the product of that n numbers.
So, the geometric mean is equal to \(\sqrt{a.b}\)
Here, a = 11 and b = 8
The geometric mean of this is equal to = \(\sqrt{11.8}\) = \(\sqrt{88}\)
