Answer:
73
Step-by-step explanation:
Angle JID is supplementary to Angle JIH so:
180- Angle JIH= Angle JID
180-107=73
Angle JID is opposite to Angle AJF(angle x)
Opposite angles are always equal
Angle JID=Angle AJF(x)
73=Angle AJF(x)
The graph of a function is given. It is required to find the function that represents the graph.
Notice from the graph that the function has roots or zeros at -3,-2, and 2.
Hence, the function takes the form:

Where a is a constant to be determined.
Notice that the given graph passes through the point (0,-12).
Substitute x=0 and f(x)=-12 into the equation of the function to find a:

Hence, the function is:

<h2>
The third option is the answer: f(x)=(x+2)(x+3)(x-2).</h2>
Answer:
1. Total distance
2. Shortest time taken
Step-by-step explanation:
Since it is a competition the distance will be the same for all participants.
therefore the information need is
1. The total distance of the competition
2. The time taken by each participant to complete the race
The winning speed is the speed is given as the distance covered in the shortest possible time.
hence the winning speed is expressed as
winning speed= distance/short time taken
Answer:
20/3 pounds of coffee that costs $12 per pound and 40/3 pounds of coffee that costs $9 per pound are required
Step-by-step explanation:
Let x be the amount of coffee that costs $12 per pound
Cost of x amount of this type coffee = 12x
We are supposed to find How much of each should be used to produce 20 pounds of the new blend that costs $10 per pound
So, Amount of coffee required that costs $9 per pound = 20-x
Cost of (20-x) amount of this type of coffee = 9(20-x)
So, 
Amount of coffee that costs $12 per pound required is
Amount of coffee that costs $9 per pound required = 20-x=
Hence 20/3 pounds of coffee that costs $12 per pound and 40/3 pounds of coffee that costs $9 per pound are required
