What is cos 45
a.
b.
c. 1
d.
e.
f.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

current in the circuit at time t is /, then the power delivered to the resistor is

my computer is slow i can not see it sorry

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
