Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,
Answer:
S = 85cm^2
Step-by-step explanation:
The surface area of a square pyramid is given by the following formula:

where it has taken into account the sum of the area of a square and four triangles:

h: slant height = 6cm
b: base = 5cm
By replacing in the formula you obtain:

hence, the surface area is 85cm^2
Answer:

Step-by-step explanation:
Given function: 
To find
, simply input
into the function:

Answer:
41.40
Step-by-step explanation: 36*.15=5.40, 36+5.40=41.40
ANSWER
b=1, c=81, and d=9.
EXPLANATION
The given function is:

This function is the same as:

To find the inverse of this function, we interchange x and y.

Solve for y:

Take square root of both sides:


Hence,
b=1, c=81, and d=9.
