The correct answers are D and C. The domain is all real numbers, and the range is anything greater than 0 hope this helps.
Answer:
the last one is correct answer
To convert radians to degrees, make use of the fact that pi<span> radians equals one half circle, or 180º.</span>
<span>This means that if you divide radians by </span>pi, the answer is the number of half circles. Multiplying this by 180º will tell you the answer in degrees.
<span>So, to convert radians to degrees, multiply by <span>180/</span></span>pi, like this:
Degrees= radians X 180/pi
<span> </span>

Step-by-step explanation:
C = 14.85
S = 16.90
c = 5.99
d = 6.99
3) 0.2(3C+2d)
round C to 15 and d to 7 cause that's about right
No cause that's about 12 and 5 is way too low.
So actually work it out now
0.2(3(14.85)+2(6.99))
0.2(44.55+13.98)
0.2(58.53)
11.706 but in terms of money it would be 11.71
4) 5S+5C+5c+5d
C is about 15, S is about 17, c is about 6, d is about 7
that is about 225
That seems reasonable.
(The real total though is 2223.65)
5) t=1.39
14.85+1.39x=20
Lets round those numbers again to make it easy to work with
15+1.5x=20
1.5x=5
x=3.33333
No, you cannot add 4 toppings and still pay $20
He over estimated
1.39x=5.15
x=3.70503597
you can get 3.
Take the equation and put it into ax² + bx + c = 0.
3x² + 4x - 6 = 0
a = 3
b = 4
c = -6
The quadratic formula is :
x = -b ± √b² - 4ac / 2a
Substitute the values.
x = -4 ± √4² - 4(3)(-6) / 2(3)
x = -4 ± √16 + 72 / 6
x = -4 ± √88 / 6
x = -4 ± 2√22 / 6
Simplify the equation by factoring out the 2.
x = -2 ± √22 / 3
Solutions :
x = -2 + √22 / 3
x = -2 - √22 / 3
