Find the solutions of each equation on the interval [0,2pi)
sin(3pi/2+ x)+sin(3pi/2 +x)= -2
Answer:
x=0
Step-by-step explanation:
You can combine the equation to get 2sin(3/2 +x) = -2
divide both sides by 2 and you get the equation equal to -1. sin is equal to -1 when the value inside is 3/2 so this is the answer.

5 pts Which side would create a right triangle if the first two sides have lengths 7 and 123 5 pts Which side would create a right triangle if the first two sides have lengths 7 and sq rt 123
Answer:
sqrt(172) = hypotenuse
Step-by-step explanation:
IF those are the leg lengths (sides) and not the hypotenuse, then use Pythagorean theorem
c^2 = 7^2 + sqrt (123) ^2
c = sqrt (172)
If sqrt 172 is the hypotenuse :
(sqrt123)^2 = 7^2 + x^2
then x = sqrt (74 )

x+6y=28, solve for y
Answer:
[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]
Step-by-step explanation:
So when you're solving for y you want to get y by it self meaning there should be nothing with y, including any coefficients. The first step is to usually move any terms to the other side and then divide by the coefficient of y so y "technically doesn't" have a coefficient, while it does, but that coefficient 1, so it doesn't really mean much.
Subtract x from both sides
[tex]6y = -x+28[/tex]
Divide both sides by 6
[tex]y = -\frac{x}{6} + \frac{14}{3}[/tex]
The given equation solved for y as y = (28 - x)/6.
The given equation is x+6y=28.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solved for y as follows
Here, x+6y=28
⇒ 6y = 28 - x
⇒ y = (28 - x)/6
Therefore, the given equation solved for y as y = (28 - x)/6.

A rectangle with base b and height h has an area of 235 square-inches. Express the perimeter of the rectangle as a function of its base
The perimeter of the rectangle as a function of its base is P = 2(b + 235/b)
What are perimeters?The perimeter of a shape is the sum of the side lengths of the shape For all regular quadrilaterals, you add up the side lengths to determine the area
How to express the perimeter of the rectangle as a function of its base?The given parameters are
Area = 235 sqare inches
The area of a rectangle is calculated using
Area = Base * Height
Note that the area of a shape is the amount of space on the shape
Recall that the area of a rectangle is calculated using
Area = Base * Height
Rewrite the above equation as
A = bh
So, we have
bh = 235
Make h the subject of the formula
h = 235/b
The perimeter of the rectangle is
P = 2(b + h)
So, we have
P = 2(b + 235/b)
Hence, the perimeter of the rectangle as a function of its base is P = 2(b + 235/b)

DEF and RST are complementary angles. If DEF is (3(-5 + 2x)) and RST is (x - 7), what is the measure of DEF?
From the given information, the measure of DEF is 81°
Calculating the measure of anglesFrom the question, we are to determine the measure of DEF
From the given information,
DEF and RST are complementary angles. This means they sum up to 90°
Thus,
(3(-5 + 2x)) + (x - 7) = 90
(3(-5 + 2x)) + (x - 7) = 90
(-15 + 6x) + (x - 7 ) = 90
-15 + 6x + x - 7 = 90
6x + x = 90 + 15 + 7
7x = 112
x = 112/7
x = 16
Then, substitute the value of x to determine the measure of DEF
(3(-5 + 2x))
= (3(-5 + 2(16)))
= (3(-5 + 32))
= (3(27))
= 81°
Hence, the measure of DEF is 81°

For a certain company, the cost for producing x items is 60x+300 and the revenue for selling x items is 100x−0.5x2 .
The profit that the company makes is how much it takes in (revenue) minus how much it spends (cost). In economic models, one typically assumes that a company wants to maximize its profit, or at least wants to make a profit!
Part a: Set up an expression for the profit from producing and selling x items. We assume that the company sells all of the items that it produces. (Hint: it is a quadratic polynomial.)
Part b: Find two values of x that will create a profit of $50 .
The field below accepts a list of numbers or formulas separated by semicolons (e.g. 2;4;6 or x+1;x−1 ). The order of the list does not matter. To enter a−−√ , type sqrt(a).
The equation for the profit from selling the items is P = 40x-0.5x²-300. The values of x are 10 and 70.
How to solve for the expressionWe have the cost function in this question to be
Cx = 60x+300
Revenue = 100x−0.5x²
A. The revenue function is stated as the revenue - cost
= (100x−0.5x²)-60x+300
We have to open the equation
40x-0.5x²-300
B. when profit is 50 dollars
50 = 40x-0.5x²-300
We have to multiply both sides by 10
500 = 400x - 5x² - 3000
We have to collect like terms and form a quadratic equation
5x² - 400x - 3500 = 0
We have to solve the quadratic equation above using a quadratic calculator.
Hence
x = 10, 70
So the two values that would create a profit of 50 dollars is 10 and 70.
