Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

<em>First, square 5 to get 25.</em>

25 + 4((5 * 6)/2)

<em>Now multiply 5 * 6 to get 30.</em>

25 + 4(30/2)

<em>Then divide 30 by 2 to get 15.</em>

25 + 4(15)

<em>Now multiply 4 by 15 to get 60.</em>

25 + 60

<em>Lastly, add 25 and 60 to get 85.</em>

The entire square pyramid's surface area is 85 square meters.

Grant's credit card has an apr of 11.28% and it just changed its compounding period from monthly to daily . What happen to the i
madreJ [45]

Answer:

C. It will increase by about 0.6%

Step-by-step explanation:

Since, the effective interest rate is,

r=(1+\frac{i}{n} )^{n} -1

Where, i is the stated interest rate,

n is the number of compounding periods,

Here, i = 11.28 % = 0.1128,

n = 365  ( 1 year = 365 days ),

Hence, the effective interest rate would be,

r=(1+\frac{0.1128}{365})^{365}  -1

=0.119388521952

Now, the changes in effective interest rate = Effective interest rate - Stated interest rate

= 0.119388521952 - 0.1128

= 0.006588521952 ≈ 0.006 = 0.6 %  

Hence, It will increased by about 0.6 %,

Option A is correct.

Hope this helps :)
