Answer:
y - 0.32y = 0.68y
y + 0.32y = 1.32 y
Step-by-step explanation:
To simplify expressions, add/subtract using the coefficients of the terms.
y – 0.32y should be 1 - 0.32 = 0.68. This simplifies to 0.68y.
y + 0.32y should be 1 + 0.32 = 1.32. This simplifies to 1.32y.
Answer:
answer is {-4.42, 12.54}
Step-by-step explanation:
v^2 - 8v - 59 = -2
v^2 - 8v = 57
(v - 4)^2 - 16 = 57
(v - 4)^2 = 73
Taking square roots:-
v - 4 = +/- √73
v = √73 + 4 or - √73 + 4
v = -4.54 , 12.54
Answer: 150
We know that cos Ф = sin (90 - Ф)
If Ф = 150, then:
cos 150 = sin (150 - 90)
cos 150 = sin 60
Using the equation they gave us:
cos 150 = sin ( 
- 10)
cos 150 = sin 60
The rule when an exponent is raised by another exponent is:
(a^b)^c = a^(b*c)
In this case:
(4^3)^5
4^(3*5)
4^15
Value of the CD after 3 months is given by 300(1 + 0.03 / 4) = 300(1 + 0.0075) = 300 x 1.0075 = $302.25.
Therefore, interest for 3 months = $302.25 - $300 = $2.25
