Answer:
Step-by-step explanation:
From the graph, we can conclude the following points:
1. Number of zeros = 4 ( As the graph intersects or touches the x axis at 4 points.)
2. Number of turning points are 6. ( As there are 3 minimums and 3 maximums)
3. Number of zeros with even powers are 3. ( As the graph touches the x axis at 3 points)
Among all the four options, only the first option fulfills all the above points.
The above function has 4 zeros at
The above function has 3 even zeros
Now, number of turning points for the above function is given as:
Turning points = Number zeros + Number of even zeros - 1 = 4 + 3 - 1 = 6
Therefore, the correct option is option 1.
Answer:
The total they paid was $58.8685
Step-by-step explanation:
Let us solve the question using the percentage method
∵ Sergio went to dinner with his brother
∵ The bill was $51.19
∵ They left a 15% tip
→ That means they pay extra money 15% of $51.19
∴ The total they paid = the bill + 15% of the bill
∵ 15% of the bill = 15% × 51.19
→ Change 15% to a decimal by divide it by 100
∴ 15% of the bill = × 51.19
∴ 15% of the bill = 0.15 × 51.19
∴ 15% of the bill = $7.6785
→ Substitute it in the total they paid
∵ The total they paid = 51.19 + 7.6785
∴ The total they paid = $58.8685
∴ The total they paid was $58.8685
