Answer:
B. (3, 0)
Step-by-step explanation:
The x-intercept signifies the location on the graph where it intersects the x-axis.
At the x-intercept, y=0 or f(x)=0.
Therefore, you need to examine the table for the instance where f(x)=0.
The value f(x)=0 is found at x=3 in the table.
We express this as an ordered pair.
Hence, the x-intercept is (3,0).
The right option is B.
1,680 grams
To determine this, we can set up a proportion as follows:
grams/people=grams/people
The recipe requires 480 grams for 4 individuals and we need to find how many grams (x) are necessary for 14 individuals.
480 grams/4 people=x grams/14
480/4=x/14
Now, let's isolate x, the grams necessary for 14 people. Currently, x is divided by 14, so we will multiply both sides by 14 as multiplication is the inverse of division.
14(480/4)=(x/14)14
14(480/4)=x
14*120=x
1680=x
Thus, she requires 1,680 grams of couscous to serve 14 individuals.
Response:
The height of the water when it reaches 4 inches is 
.
Detailed Explanation:
Flow rate of water from the cone = R=
Height of the cup = h = 6 inches
Radius of the cup = r = 3 inches
r = h/2
Volume of the cone = 
h = 4 inches
The height of the water when it is 4 inches deep is .
B, the points E, F, and H are located at the bottom of the figure.
