(-4)^-6*(-4)^7 = (-4)^1 = -4
answer a. -4
We are given that the angle a is the right angle. So let
us work from this.
ab = 12 (the vertical side of the triangle)
bc = 13 (which if drawn can be clearly observed to be the
hypotenuse) = the side opposite to angle a
ca = 5 (the horizontal side of the triangle)
Since we are to find for the cosine ratio of angle c or
angle θ, therefore:
cos θ = adjacent side / hypotenuse
cos θ = ca / bc
cos θ = 5 / 13
Check out the attached image below for the illustration
of the triangle.
To answer the problem above, divide the numerical portion and the exponential portion of the given numbers. 4.5 divided by 9 is 0.5. Furthermore, 10^3 divided by 10^7 is 10^-4. The answer is
0.5 x 10^-4
This may still be written in a standard form,
5 x 10^-5
Thus, the answer is <em>5 x 10^-5</em>.
Answer:
option A
Step-by-step explanation:
given,
the bank branch is offering $1,000 certificates of deposit.
Rate of interest per year = 4 % = 0.04
The bank is selling certificates with terms of 1, 2, 3, or 4 years
total amount = A , in dollar
time of investment = k years
4 k% is added to the original deposit.
A = P + P r t
A = P (1 + r t)
A = P (1 + 0.04 k)
the correct answer is option A
