Answer:
x = 3
Step-by-step explanation:

56 is not equal to 30
The total interest earned is 40.75 and the final balance is 65.75
<u>Solution:</u>
Given, principle amount P = 25
Interest rate
Times compounded per year n = 12
Time in years t = 30

On substituting the values we get
![A = 25 [ 1+ \frac{0.0325}{12}]^{12\times30}= 25 [2.63]= 65.75](https://tex.z-dn.net/?f=A%20%3D%2025%20%5B%201%2B%20%5Cfrac%7B0.0325%7D%7B12%7D%5D%5E%7B12%5Ctimes30%7D%3D%2025%20%5B2.63%5D%3D%2065.75)
Interest I = A - P [since, A = P+I]

Answer:
Step-by-step explanation:
Tangent of an angle in right angled triangle is defined as the ratio of opposite side to adjacent side.
In triangle
,
Given that
and 
tan(
)=
=
In triangle
,
Given 
tan(
)=
=
Since,angle
is same as angle
,their tangents are equal.

So,
Answer:
x=-4.5
Step-by-step explanation:
Rewrite the problem as an equation:
4x+16=-2
1) Subtract 16 from both sides:
4x=-18
2) Divide both sides by 4:
x=-4.5
