An electronics store discovers that it can sell 5 televisions per day by pricing them at $150. When the televisions are on sale

Nataly [62]

Answer:

$p = -10x + 200$

$m = -10x^2 +200x$

Step-by-step explanation:

We know that at a price of $ 150, 5 televisions are sold and at a price of $ 100, 10 televisions are sold.

We must write a linear equation for this situation.

The equation of the line will have the following form

$p = mx + b$

Where m is the slope of the line and b is the intercept with the p axis

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{100-150}{10-5}=-10$

$b=p_1-mx_1\\\\b=150-(-10)(5)\\\\b=200$

The equation is:

$p = -10x + 200$

Now we know that the revenue m is the product of the price p for the quantity sold x.

$m = p * x$

$m=(-10x + 200)*x$

$m = -10x^2 +200x$

Sin155° = _____ sin25° sin(-25)° -sin25°

patriot [66]

Answer:

sin 25

Step-by-step explanation:

sin(A − B) = sinA cosB − cosA sinB

sin 155

sin( 180 -25)

A = 180 B = 25

sin180 cos25 − cos180 sin25

Sin 180 = 0

cos 180 = -1

0 - (-1) sin 25

sin 25
