Answer:
if sin (x-3) degrees = cos (2x+6) degrees, find the value of x.
----------
Note: sin and cos are complementary functions....
sin(x) = cos (90-x)
-------------------
Your Problem:
sin(x-3) = cos(90-(x-3))
Equation:
90-[x-3] = 2x+6
90-x+3 = 2x+6
3x = 93-6
x = 31-2
x = 29
Step-by-step explanation:
Answer:
B. 350 minutes
Step-by-step explanation:
(a) Using the completing the square method, we need to write into the form of where , so
Expand to find the value of c
Notice that we get back the first two terms, the and the .We need to get rid of the last term of '9' as the term was not in the original form. The final form will look like
Hence,
(b)
(c) , square root both sides plus and minus of 2 Hence
Answer:
$1.59 for a pint,
two dollars for a quart,
299 for a gallon
Step-by-step explanation:
Since, rate is used to compare different kinds of quantities and it is the ratio of the quantities,
Also, unit rate states the amount of first quantity corresponding to the unit amount of second quantity,
When we talk about the unit rates for a quantity,
Then it shows the price of the quantity per unit amount.
Thus, by the above explanation it is clear that,
The unit price for representing the price of juice would be,
$1.59 for a pint,
two dollars for a quart,
299 for a gallon.
Note : we do not consider 'one dollar for 12 ounces' a unit price because it is not the price per 1 ounce.
