Final answer:
The sine of angle A can be found using the relationship between the tangent and cosine of angle A. By substituting the given values into the sine identity, we can determine that the sine of angle A is 915.
Explanation:
To find the sine of angle A, we can use the trigonometric identity: sin A = opposite/hypotenuse. Given that the tangent of angle A is 912 and the cosine of angle A is 1215, we can use the relationship between these trigonometric functions. Since tan A = opposite/adjacent and cos A = adjacent/hypotenuse, we can substitute these values into the identity to solve for the sine of angle A.
From tan A = 912, we can rearrange the equation to get opposite/adjacent = 912.
From cos A = 1215, we can rearrange the equation to get adjacent/hypotenuse = 1215.
Substituting these values into the sine identity, we get sin A = opposite/hypotenuse = (912)(1215).
Therefore, the sine of angle A is 915.

Answer:
x = 10, y = 20
Step-by-step explanation:
Because this is a geometric sequence, we'll call the rate of change z. Because 40 is 3 terms away from 5, we can write 5 * z * z * z = 5z³ = 40.
z³ = 8 → z = 2
Now, we simply multiply 5 by 2 to get x, which is 10, and then we multiply x by 2 to get 10 * 2 = 20 for y. Hope this helps!
Final answer:
To find the values of x and y in the given geometric progression, we use the concept of a common ratio. By setting up equations based on the definition of a geometric progression, we can solve for x and y. In this case, x is 10 and y is 20.
Explanation:
To find the values of x and y in the given geometric progression, we need to identify the common ratio between the terms. In a geometric progression, each term is obtained by multiplying the previous term by the common ratio. Therefore, we have:
- 5 * r = x
- x * r = y
- y * r = 40
From the first equation, we can substitute x as 5 * r in the second equation:
5 * r * r = y
Then, we substitute y as 5 * r * r in the third equation:
5 * r * r * r = 40
Simplifying the equation, we get:
r^3 = 40/5 = 8
Taking the cube root of both sides:
r = 2
Substituting this value of r back into the equations, we find that x = 10 and y = 20.

te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87
your equation for the prblem is a=p(1-r)^t
when you put $28,000 as A and make 13% into 0.13 and solve your B comes to 0.87. hope this was helpful :)
