The mathematical expression of the given complex number above is -5 + 4i. The conjugate of this complex number is that which has an opposite operation. The given is an addition operation. That is -5 - 4i. Therefore, the answer is the third among the choices.
A diagram would be nice. If this is a right triangle, and one acute angle is 53 deg, then the other is 37 deg. You don't specify any dimensions, so all you can do is use theoretical values here.
If x is opposite the 53 deg angle, and the length of the hypotenuse is h, then side x has length h(sin 53 deg) = 0.799h.
9x + 1 = 5x - 15
Subtract 1 from both sides.
9x = 5x - 16
Subtract 5x from both sides.
4x = -16
Divide both sides by 4.
x = -4
Answer:
your answer is 18
Step-by-step explanation:
T = 7.23 years (either 5 or 10, you choose)
Equation:
t = (1/r)(A/P - 1)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 8.3%/100 = 0.083 per year,
then, solving our equation
t = (1/0.083)((80000/50000) - 1) = 7.23
t = 7.23 years
The time required to get
a total amount, principal plus interest, of $ 80,000.00
from simple interest on a principal of $ 50,000.00
at an interest rate of 8.3% per year
is 7.23 years (about 7 years 3 months).
