If it is 40% off then it is 100-40 = 60% of original price. So we do 180$ * . 6 = $108 before tax. To add on tax we do: 100 + 5 = 105% of that price.

Help me out the number inside the triangle is really throwing me off tbh

prisoha [69]

We are given an angle of 60° and a side of 15 cm.

We are given the opposite and is looking for the hypotenuse so we will use the sine ratio to find x.

sin = opp/hyp

hyp = 15 / sin 60

hyp = 17.32...

//

We can also use the tangent ratio to find the adjecent and then use pythagorean to find x.

tan = opp/adj

adj = 15 / tan 60

adj = 8.660.....

8.660....² + 15² = 300²

since the square root of 300 is an irrational number, we have to turn it into a mixed radical.

The answer would be the top one.

A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the giv

SCORPION-xisa [38]

Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

$y=-x^2+64x-292$

Required

Determine the maximum profit

This is calculated by calculating the maximum of the function.

A quadratic function is of the form

$y = ax^2 + bx + c$

and its maximum is:

$Max = \frac{-b}{2a}$

So: $y=-x^2+64x-292$

We have that

$a = -1$

$b = 64$

$c = -292$

$Max = \frac{-b}{2a}$

$Max = \frac{-64}{2 * -1}$

$Max = \frac{-64}{-2}$

$Max = 32$

<em>Hence, the maximum amount of profit is 32</em>

What is the equation of the line that passes through the point (2, -4) and has a<br> slope of 2

oee [108]

Answer:

y = 2x - 8 OR 4 - 2x = -4 - y

Step-by-step explanation:

Use the point-slope form m(x₁-x₂) = (y₁-y₂); m means slope

plug in your numbers:

2(2-x₂) = (-4-y₂)

4 - 2x = -4 - y

or to put it into Y=mx + b:

y = 2x + 8
