Answer: sec (75) or csc (15)
Step-by-step explanation:
255 is in the 3rd quadrant where the secant is. Here, the tangent and cotangent is positive.
Reference angle for 255 is,
255 - 180 = 75 degrees.
Therefore, sec (255) = sec (75)
= csc (90 - 75) = csc (15)
Answer:
Step-by-step explanation:
We can use the distance formula derived from the Pythagorean theorem
D = 
the two points given are
(0, 3) and (-2, -3)
Answer:
b) $475
Step-by-step explanation:
if it has a diameter of 22 feet, that means it has a radius of 11 feet
the formula of the area of a circle is πr². so square the radius and you will get 121, multiply that by π and you get 380
Now we know the area is 380 square feet, so multiply that by $1.25 and the answer is $475
The common difference is -1/4.
You can figure this out by subtracting each value in the sequence by the value right before it. Ex. 1/4 - 1/2 = -1/4
Step-by-step explanation:
PART A
a=total amount
c=cans of oil
g=gasoline
a=2.65g+3.45c
PART B
a=2.85(8.4)+3.15(6)
a=23.94+18.90
a=42.84
Hope that helped =)
