True
<u>EXPLANATION</u>
The given trigonometric equation is
Recall the double angle identity:
We apply this identity to obtain:
We maintain the LHS and simplify the RHS to see whether they are equal.
Expand the parenthesis
Recall that:
We apply these identities to get:
Also
Therefore the correct answer is True
Answer : option B
We have -2 in the given option
Lets use synthetic division and divide by -2
First write the coefficient of all the terms in f(x)
-2 3 10 4 -8
0 -6 -8 8
------------------------------------------------------
3 4 -4 0
We got remainder =0 , so -2 is one of the zero
Resultant expression is 3x^2 + 4x -4
Lets use synthetic division and divide by -2 again
-2 3 4 -4
0 -6 4
------------------------------------------------------
3 -2 0
We got remainder =0 , so -2 is again a zero
Resultant expression is 3x - 2
we set 3x -2 =0
Add 2 on both sides
3x = 2
Divide by 3 on both sides
So zeros are
Answer:
Step-by-step explanation:
divide the price of the olive oil by the volume of the olive oil
to find the price per ounce. 5.88/25oz=0.2352 dollars/ounce. Then you
have to multiply the volume of the bottle by .60 to find what 60% of the
volume is.
0.60x25=15 ounces. since in the first two weeks she used 15
ounces which has a price of 0.2352 dollars/ounce you have to multiply
15 by 0.2352 which equals 3.528 dollars.
X + 4y = -9 . . . (1)
2x + 5y = -6 . . . (2)
From (1): x = -9 - 4y . . . (3)
Substituting (3) into (2) gives, 2(-9 - 4y) + 5y = -6
-18 - 8y + 5y = -6
Required equation is -18 - 3y = -6
