Prove that:
Remember that:
We wish to remove this add (A+B).
Then we de identity:
Let p=2α and q=8α
.075+.006x > 0.81 which inequality shows all the possible values of x?
Answer:
B
Step-by-step explanation:
This is a quadratic in cosines
Factor by considering the factors of the product 2 × 1 = 2 which sum to give the coefficient of the cos x term (3 )
the factors are + 2 and + 1
use these factors to split the middle term
2cos²x + 2cosx + cosx + 1 = 0 (factor by grouping )
2cosx(cosx + 1) + 1(cosx + 1) = 0 (take out common factor (cosx + 1) )
(cosx + 1)(2cosx + 1) = 0
equate each factor to zero and solve for x
cosx + 1 = 0
cosx = - 1 ⇒ x = π
2cosx + 1 = 0
cosx = -
since cosx < 0 then x is in second/ third quadrant
x = or x =
Parallelogram
so
AE = EC and DE = EB
from here you can find x and y
AE = EC
4x - 2 = x+28
4x - x = 28 +2
3x = 30
x = 10
DE = EB
4y - 7 = y + 14
4y - y = 14 + 7
3y = 21
y = 7
answer: x = 10 and y = 7
You just put the number in for m with the formula you have. 12 months will give you T=2800.4*12 T will be 62) $33604.80 and with 36 months T=2800.4*36 will be 63) $<span>100814.40</span>
