By the use of trigonometric functions, the exact value of the sine of the double of the angle ABC is equal to 24 / 25.

<h3>How to determine the exact value of a trigonometric function of a double angle</h3>

Herein we find a right triangle whose side measures are known and we need to determine the exact value of the sine of twice the angle ABC. By trigonometry, this expression is equal to:

sin 2B = 2 · sin B · cos B

Where B is an abbreviation for m ∠ ABC.

Then, by definitions of the trigonometric functions of sine and cosine and knowing that AC = 4, BC = 3 and AB = 5:

sin 2B = 2 · (4 / 5) · (3 / 5)

sin 2B = 24 / 25

The exact value of the sine of the double of the angle ABC is equal to 24 / 25.

If the Density of an object is 5.2 g/cm3, and its volume is 3.7 cm3, what is its mass? 19 g 10 g 15 g 22 g
marshall27 [118]

Answer:

The closest answer would be 19g.

Step-by-step explanation:

1)The formula for density is mass divided by volume

2) That means you have to divide all the masses by 3.7 cm3 to find which one is closest to 5.2 g/cm3

Solve for p, w = Q+P<br> -------<br> Q-QP
7nadin3 [17]
Alright, here it is
w=(q+p)/(q-pq)
factor out the q in the bottom part

w=(q+p)/[(q)(1-p)]
multiply both sides by q
wq=(q+p)/(1-p)
add 1 to both sides, but add (1-p)/(1-p) to the right side since that equals 1
wq+1=(q+1+p-p)/(1-p)=(q+1)/(1-p)
multiply both sdies by (1-p)
(wq+1)(1-p)=q+1
divide both sdies by (wq+1)
1-p=(q+1)/(wq+1)
subtract 1 from both sdies
-p=[(q+1)/(wq+1)]-1
multiply by -1
p=-[(q+1)/(wq+1)]+1 or
p= -\frac{(q+1)}{(wq+1)}+1

Hi! If you know angles this is the perfect question. Please help thank you!!! &lt;3
ElenaW [278]

Answer:

x = 60

Step-by-step explanation:

Add up all the angles, they make 360 since it forms a full circle

(2x-10) + (2x+40) +90 = 360   Combine like terms

4x + 120 = 360 solve for x

4x = 240

x = 60

Point X is located at (2,-6), and point Z is located at (0,5). Find the y value for point Y that is located 1/5 the distance fro
aliya0001 [1]

The y-difference between the points is 5-(-6) = 11. One-fifth of that is 11/5 = 2.2. Adding that to the y-value of point X means ...

... the y-value of point Y is -6+2.2 = -3.8
