Answer:

b = 6

Step-by-step explanation:

The above questions is trigonometry where hypothenus = 12; opposite = b; and adjacent = a. Applying SOHCAHTOA principle, the appropriate is

Sine = opposite/hypothesis, since we are to find the value of b. Thus,

Sine 30 = b/12

0.5 =b/12

By cross multiplying,

b = 0.5 × 12

b = 6

Answer:

The correct answer is b = 6 √3 units

Step-by-step explanation:

Let's recall that we can use the following ratio for the sides of a 90 - 60 - 30 triangle:

1 : √3 : 2, where 2 is the hypotenuse.

Upon saying that, we have that in our triangle:

Hypotenuse = 12 units

a = 6 units

b = 6 √3 units

The correct answer is b = 6 √3 units

25x^2+9y^2+72y-81=0. Find the standard form of the equation by completing the square. Then identify and graph each conic.

olasank [31]

25x² + 9y² + 72y - 81 = 0
 25x² + 9y² + 72y - 81 + 81 = 0 + 81
 25x² + 9y² + 72y = 81
 25x² + 9(y² + 8y + 16) = 81 + 9(16)
 25x² + 9(y² + 4y + 4y + 16) = 81 + 144
 25x² + 9(y(y) + 4(y) + 4(y) + 4(4)) = 225
 25x² + 9(y(y + 4) + 4(y + 4)) = 225
 25x² + 9(y + 4)(y + 4) = 225
 25x² + 9(y + 4)² = 225
 225 225 225
 x² + 9(y + 4)² = 1

By selling a watch on 400 and 460’. Loss and profit happened respectively.if the loss and profit are equal, find cp.

Maslowich

Answer:

430

Step-by-step explanation:

Given :-

By selling a watch on 400 and 460’. Loss and profit happened respectively.
The loss and profit are equal.

And we need to find out the CP .So ,

Let :-

CP be x
Profit and Lost be y .

According to the Question :-

$:\implies$ 460 = x + y ( Profit)

$:\implies$ 400 = x - y ( Loss)

Adding both :-

$:\implies$ 460 + 400 = x + y + x - y

$:\implies$ 860 = 2x

$:\implies$ x = 860/2

$:\implies$ x = 430

Hence the Cost price of the watch is 430 .
