Answer:
9.2 cm.
Step-by-step explanation:
A pyramid has a horizontal square base of 12 cm. The vertex of the pyramid is 7 cm vertically above the base.
So, the height of the pyramid is 7 cm and half-length i.e. half base is equal to cm.
Now, the slant height of a pyramid is the altitude of the side triangles.
Therefore, the length of the slant height will be equal to cm ≈ 9.2 cm. (Answer)
The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901
The amount of money gained after an investment is compounded is given by:
Where P is principal, A is the final amount, r is the rate, n is the number of times compounded per period and t is the time
Given that P = $1689, t = 4, r = 3% = 0.03, n = 1, hence:
The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901
