Answer:
No
Step-by-step explanation:
Every x value in the domain should only have 1 y value. In the graph, for x=5 (the input) there are 2 y values (6 and -6) so this is not a function.
Answer:
Step-by-step explanation:
Use Pythagorean's theorem. If the sides satisfies Pythagorean theorem, then, they form a right angled triangle.
The longest side is hypotenuse.
Hypotenuse² = base² + altitude²
10² = 6² +8²
100 = 36 + 64
100 = 100
So, 6cm, 8cm, 10 cm makes an right angles triangle.
Answer: (Supermart) Equation 1 = $2.70÷5 lb = $0.54 per lb
(Market One) Equation 2 = $2.60÷4 lb = $0.65 per lb
Since the unit price of bananas per lb in Supermart is less than the unit price of bananas per lb in Market One, Supermart has the better price.
Answer:
7500 km
Step-by-step explanation:
BC= √3250²-3000²= 1250 km
Complete travel= 3250 km+1250 km+3000 km= 7500 km
Wen is incorrect.
The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.
