solve for x and y, show your work with your answer.
Answer and Step-by-step explanation:
This problem involves the use of trigonometric functions.
First, we will use the tangent trig function, and then the sine trig function.
[tex]tan(32) = \frac{x}{15}[/tex]
We solve for x by multiplying both sides by 15.
15(tan(32)) = x
Put this into a calculator and solve.
x = 9.373
Now, we solve for y.
[tex]sin(32) = \frac{9.373}{y}[/tex]
We multiply by y on both sides first.
y(sin(32)) = 9.373
Now, we divide each side by sin(32).
[tex]y = \frac{9.373}{sin(32)}[/tex]
Put this into a calculator and solve.
y = 17.6877
x = 9.373
y = 17.6877
These are your answers.

Please find the area of D, E, and F.
This would be appreciated :)
Answer:
Using graph for units
D=1/2(6)(9)=27 sq units
E=1/2(7)(6)=21 sq units
F=1/2(6)(8)=24 sq units
Step-by-step explanation:
Answer:
D=27 units, E=21 units, F=24 units
Step-by-step explanation:
The formula for area of a triangle is (BASE * HEIGHT)/2
For triangle D, the base is 9 units and the height is 6 units. Then you can apply the formula and do 9*6 which is 54 and then do 54/2 which is 27 units.
Similarly, the base for E is 6 units, and the height is 7 units. So you do 6*7 which is 42 and then do 42/2 which is 21 units.
Again, the base for F is 6 units, and the height is 8 units. Then again, using the formula, we can do 6*8 which is 48 and then do 48/2, which is 24 units.

the perimeter of a playing field for a certain sport is 262 ft. the field is a rectangle and the length is 41 ft longer than the width. find the dimensions
Answer: The width of the playing field = 45 ft
length of playing fiels = 86ft
Step-by-step explanation:
Step 1
Perimeter of rectangular field is given as 2 ( L+ b)
Let the width be represented as x
such that the length = 41 ft longer than the width be x+ 41
To find the length and breadth
Step 2
Perimeter = 2( L+ b)= 2l + 2b
Perimeter = 2 (x+41 ) + 2 x = 262
2x + 82 + 2x= 262
4x+ 82= 262
4x= 262 - 82
4x= 180
x= 180/4
x= 45
width= 45 ft
length = x+ 41= 45+ 41= 86ft

yis inversely proportional to the square of x.
A table of values for x and y is shown.
a) Express y in terms of x.
b) Work out the positive value of x when y = 25
Answer:
(a) [tex]y = \frac{4}{x^2}[/tex]
(b) [tex]x = \frac{2}{5}[/tex]
Step-by-step explanation:
Given
Variation: Inverse proportional.
This is represented as:
[tex]y\ \alpha\ \frac{1}{x^2}[/tex]
See attachment for table
Solving (a):
First convert variation to equation
[tex]y = k\frac{1}{x^2}[/tex]
From the table:
[tex](x,y) = (1,4)[/tex]
So, we have:
[tex]4 = k * \frac{1}{1^2}[/tex]
[tex]4 = k * \frac{1}{1}[/tex]
[tex]4 = k * 1[/tex]
[tex]4 = k[/tex]
[tex]k = 4[/tex]
Substitute 4 for k in [tex]y = k\frac{1}{x^2}[/tex]
[tex]y = 4 * \frac{1}{x^2}[/tex]
[tex]y = \frac{4}{x^2}[/tex]
Solving (b): x when y = 25.
Substitute 25 for y in [tex]y = \frac{4}{x^2}[/tex]
[tex]25 = \frac{4}{x^2}[/tex]
Cross Multiply
[tex]25 * x^2 = 4[/tex]
Divide through by 25
[tex]x^2 = \frac{4}{25}[/tex]
Take positive square roots of both sides
[tex]x = \sqrt{\frac{4}{25}[/tex]
[tex]x = \frac{2}{5}[/tex]

Finding angle measures of a triangle given angles with variables
In the triangle below, suppose that m U=(x+9)°, m = (2x+1), and mW=(7x)".
Find the degree measure of each angle in the triangle.
Answer:
∠U = 26°
∠V = 35°
∠W = 119°
Step-by-step explanation:
Given:
∠U = (x+9)°
∠V = (2x+1)°
∠W = (7x)°
Find:
Value of each angle
Computation:
Using angle sum property
∠U + ∠V + ∠W = 180°
(x+9)° + (2x+1)° + (7x)° = 180°
10x + 10 = 180
x = 17
So,
∠U = (x+9)° = 17 + 9 = 26°
∠V = (2x+1)° = 34 + 1 = 35°
∠W = (7x)° = 7 x 17 = 119°
Solve 2x2 + 20x = -8
Answer:x=-5/11
Step-by-step explanation:
2x+2+20x=−8
Step 1: Simplify both sides of the equation.
2x+2+20x=−8
(2x+20x)+(2)=−8(Combine Like Terms)
22x+2=−8
22x+2=−8
Step 2: Subtract 2 from both sides.
22x+2−2=−8−2
22x=−10
Step 3: Divide both sides by 22.
22x/22=-10/22

Step-by-step explanation:
Chancellor Manufacturing makes two pumps for use in household reef aquariums. The Standard pump (Model A) requires 4.5 lbs of stainless steel while the Deluxe lightweight pump (Model B) 3.0 lbs of stainless steel. There are 63 lbs of stainless steel available during this production period. The combined production of both pumps must be at least 12 pumps. There are orders for at least 6 of the lightweight Model B. Lastly, management has decided that no more than 15 Model B pumps be produced.
Required:
a. Write the LP formulation which provides the optimal production schedule for the standard and deluxe pumps such that the cost is minimized.
b. Write the above LP formulation in Standard Form.
c. Using your grid page, graph the above LP formulation. Be sure to label axes, constraints, and the feasible region.
Answer:
The answer is below
Step-by-step explanation:
Chancellor Manufacturing makes two pumps for use in household reef aquariums. The Standard pump (Model A) requires 4.5 lbs of stainless steel while the Deluxe lightweight pump (Model B) 3.0 lbs of stainless steel. There are 63 lbs of stainless steel available during this production period. The combined production of both pumps must be at least 12 pumps. There are orders for at least 6 of the lightweight Model B. Lastly, management has decided that no more than 15 Model B pumps be produced.
The cost to produce one Standard pump is $150 and to produce one Deluxe pump is $210.
Solution:
a) Let x represent model pump A and let y represent model pump B.
Since There are 63 lbs of stainless steel available, hence:
4.5x + 3y ≤ 63
Both pumps must be at least 12 pumps. Therefore:
x + y ≤ 12
There are orders for at least 6 of the lightweight Model B:
y ≥ 6
Also, no more than 15 Model B pumps be produced:
y ≤ 15
The cost to produce one Standard pump is $150 and to produce one Deluxe pump is $210. The cost equation is:
Minimize Cost = 150x + 210y
b)
Hence the LP formation is:
Minimize Cost = 150x + 210y
4.5x + 3y ≤ 63
x + y ≤ 12
y ≥ 6
y ≤ 15
x ≥ 0.
c) The LP problem was solved using geogebra online graphing tool.
The points that satisfy the problem are:
(0, 6), (0,12), (6, 6)
At (0,6); cost = 150(0) + 210(6) = 1260
At (0,6); cost = 150(0) + 210(12) = 2520
At (6,6); cost = 150(6) + 210(6) = 2160
Hence the minimum cost is at (0, 6)
Is x = -4 a solution to these equations? Show your work and write YES or NO.
1. 3(2x-4) = -36
2. 5x - 6x - x = 18
3. 5 - 2(3x - 1) = 31
Answer:
1. Yes
2. No
3. Yes
Step-by-step explanation:
We have three equations where x is equal to -4. We are then asked if -4 are a solution to these equations.
To solve we need to substitute the x in every equation for -4. Start :
1.
3(2(-4) - 4) = -36
3(-8 - 4) = -36
-24 - 12 = -36
Therefore -4 is a solution.
2.
5(-4) - 6(-4) - (-4) = 18
-20 + 24 + 4 = 18
4 + 4 = 18
8 ≠ 18
Therefore -4 is not a solution.
3.
5 - 2(3(-4) - 1) = 31
5 - 2(-12 - 1) = 31
5 - 2(-13) = 31
5 + 26 = 31
Therefore -4 is a solution.

Step-by-step explanation:
For all Plato users.
We have to find the sum of the series has been given as.
[tex]\sum_{k=1}^{8}5(\frac{4}{3} )^{k-1}[/tex] -----(1)
If the series has been given as,
[tex]\sum_{n=1}^{k}a(r)^{n-1}[/tex] -------(2)
It's a geometric series with first term 'a' and common ratio 'r'.
Comparing both the expressions (1) and (2),
[tex]a=[/tex] 5
[tex]r=\frac{4}{3}[/tex]
Number of terms 'n' = 8
Sum of the k terms of this series is given by,
Sum = [tex]\frac{a(r^k-1)}{r-1}[/tex]
= [tex]\frac{5[(\frac{4}{3})^8-1)]}{\frac{4}{3}-1 }[/tex]
= [tex]\frac{5(9.98872-1)}{\frac{1}{3}}[/tex]
= [tex]\frac{44.9436}{\frac{1}{3} }[/tex]
= 134.83
Therefore, Option (B) is the correct option.
