The formula of the compound interest is V = V₀(1+r%)ⁿ, where V₀ is the initial amount invested, r= interest in%, n = the period or number of years
and V the new amount of his investment:
In your given formula 1250(1.03)^t which is similar to V= 1250(1+3%)^t
We notice that 1250 occupies the place of the initial investment, so Rashid
invested 1250
Answer:
Step-by-step explanation:
Looking at the right angle triangle that contains x and y, we would apply trigonometric ratio to determine x an y. Taking 60 degrees as the reference angle,
Hypotenuse = y
Adjacent side = x
Opposite side = 36
Therefore,
Sin # = opposite side / hypotenuse
Sin 60 = 36/y
y = 36/Sin60 = 36/0.8660 = 41.57
Cos # = adjacent side/hypotenuse
Cos 60 = x/41.57
x = 41.57Cos 60 = 41.57 × 0.5 = 20.785
Sin45 = z/36
z = 36Sin45 = 36 × 0.7071 = 25.4556

So for a you need to add up all the numbers and for b you need to multiply all the numbers
Can you help me I posted a new question that is worth 50 points
We have been given that the diameter of a smaller circle is 7 km and the width of the circular path is 0.5 km. We are asked to find the area of the path.
The area of the path will be equal to area of larger circle minus area of smaller circle.
, where r represents radius of circle.
We know that radius is half the diameter, so radius of smaller circle would be 
km.
The radius of the larger circle will be radius of smaller circle plus width of the path that is 
km.
Therefore, the area of the circular path is approximately 11.8 square km.
