A. x-int:-0.5,y-int:1<br>B. x-int:0.5,y-int:1<br>C. x-int:-0.5,y-int:-1<br>D. x-int:1,y-int:0.5
hodyreva [135]
The correct answer is:  [D]:  " <span>x-int : 1 ,  y-int:  0.5  " .
_____________________________________________________
Note:
_____________________________________________________
The "x-intercept" refers to the point(s) at which the the graph of a function (which is a "line", in this case) cross(es) the "y-axis".  

In other words, what is (are) the point(s) of the graph at which "x = 0<span>" ?
</span>
By examining the graph, we see that when " x = 0" ; y is equal to:  "1<span>" .
</span>
So; the "x-intercept" is at point:  "(0, 1)" ; or, we can simply say that the 
   "x-intercept" is:  "1" .

     {that is;  The "x-intercept" is: "0" ; and the "y-intercept" is:  "0.5 ".} .

Help, Find the domain of the function
adell [148]

Answer:

(-∞,∞)

Step-by-step explanation:

This would form a roughly parabolic shape that extends infinitely along the x-axis.  It would reach a height of ³√2 on the y-axis.  Because it extends infinitely left and right, it would have an infinite domain.  In interval notation, this would be (-∞,∞)

You have 10 gallons of lemonade to sell. (1 gal $\approx$ 3785 cm3) a. Each customer uses 1 paper cup. The cups are sold in pack
SpyIntel [72]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Calculating the volume of cone cup:

= \frac{1}{3}\pi r^2 h \\\\  = \frac{1}{3}\times 3.14 \times 4^2 \times 11 \\\\ = \frac{1}{3}\times 3.14 \times 16 \times 11 \\\\ = \frac{1}{3}\times 3.14 \times 176 \\\\ =  3.14 \times 58.66 \cong  184.31 cm^3

\to 10 \ gal \times  3,785\  \frac{cm^3}{gal} = 37,850\  cm^3\\\\\to 37,850 cm^3 \times  \frac{(1 \ cone)}{(184.31 \ cm^3)} \times 205.4 \ cones

When buying 5 packages (250 cones):

\to 8 \ gal \times 3,785 \ \frac{cm^3}{gal} = 30,280\ cm^3 \\\\\to 30,280 \ cm^3 \times \frac{(1\ cone)}{(184.31 \ cm^3)} \cong \ 165 \ cones

 Calculating the left over cones values:

\to 250 - 165 = 85
