Answer:
The answer is<u> D.</u> h+3/j+6.
Step-by-step explanation:
Given:
The equation h + 3 = jk + 6k.
Now, to get the mathematical expression.

So, taking
common on R.H.S we get:

Then, dividing both sides by
we get:

Thus,

Therefore, the answer is D. h+3/j+6.
Answer:

Step-by-step explanation:
Given the exponential decay function 
When
then

so the initial amount is 
The exponential decay function
has the decay factor 
In your case, the eexponential decay factor is 
According to the trigonometric functions, we can see that angle x can be found through the one that involves the adjacent side and the hypotenuse, which in this case is the cos,

then, if we apply the inverse we can find the value of x,

Answer:
Answer:
Angle 1 = 39, Angle 2 = 78 , Angle 3 = 63
Step-by-step explanation:
78/2 = 39
(Angle 2/2 = Angle 1)
78 - 15 = 63
(Angle 2 - 15 = Angle 3)
39 + 78 + 63 = 180
(Angle 1 + Angle 2 + Angle 3 = 180)
First, make it an improper fraction, 7x4 is 28. 28+1 is 29. So the improper fraction is 29/7. Then, divide 29 by 7. The answer is 4.14 rounded to the tenths place.
