Answer:

D) 55/73

Step-by-step explanation:

The question is on trigonometry. Sine of an angle is obtained using the SOH of SOHCAHTOA formula of trigonometry. SOH is an acronym for sine, opposite and hypotenuse. Sine of an angle is obtained from the ratio of opposite and hypotenuse of a given triangle. Thus, SOH

is denoted as stated below.

$sine \: \beta = \frac{opposite}{hypotenuse}$

Hence, given the above triangle,

$sine \: of \: angle \: u = \frac{ |bc| }{ |ab| } = \frac{55}{73}$

Therefore, the sine of angle u = 55/73 (D)

Answer:

10x+200 $\leq$ 375

Step-by-step explanation:

subtract 200 from both sides

10x $\leq$ 175

divide both sides by 10

x $\leq$ 17.5 cars

Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)

Alex

The value of x in the triangle is 28.1 degrees

<h3>How to solve for x?</h3>

The given triangle is a right triangle.

So, the relationship between the sides and angle x is:

sin(x) = opposite/hypotenuse

This gives

sin(x) = 8/17

Evaluate the quotient

sin(x) = 0.4706

Take the arc sin of both sides

$x = \sin^{-1}(0.4706)$

Evaluate

x = 28.1

Hence, the value of x in the triangle is 28.1 degrees

If the marginal revenue (in dollars per unit) for a month is given by MR = −0.5x + 400, what is the total revenue from the produ

Vesna [10]

Given:

Marginal revenue (in dollars per unit) for a month is

$MR=-0.5x+400$

To find:

The total revenue from the production and sale of 30 units.

Solution:

We know that, total revenue is integration of marginal revenue with respect to quantity.

$TR=\int MR dx$

$TR=\int (-0.5x+400) dx$

$TR=-0.5\int x dx+400\int 1 dx$

$TR=-0.5\times \dfrac{x^2}{2}+400x$

Now, substitute x=30 in the equation of Total Revenue (TR).

$TR=-0.5\times \dfrac{30^2}{2}+400(30)$

$TR=-0.5\times \dfrac{900}{2}+12000$

$TR=-225+12000$

$TR=11775$

Therefore, the total revenue from the production and sale of 30 units is $11,775.
