Answer:
C
Step-by-step explanation:
For this case we evaluate the function when x = 0
We then have to evaluate:
y = -2sinx - 1
y = -2sin (0) - 1
y = -1
Then, the intersection with the y-axis is -1 and the amplitude is 2.
Answer:
y = -2sinx - 1
option 2
Answer:
Carlo ran 33.3% of the miles.
Step-by-step explanation:
It sounds like David ran 2 laps for every 1 lap that Carlo ran. So, for every 1 mile that Carlo ran, David ran 2 miles, which means if you add both miles together: 1 mile (Carlo) + 2 miles (David) = 3 miles, that Carlo ran 1/3 of the miles, and David ran 2/3 of the miles. In percentages, it means Carlo ran 1/3=0.333 or 33.3% and David ran 2/3=0.666 or 66.6%
Answer:
20 students should be on each float
Step-by-step explanation:
Number of seniors = 100
Number of juniors = 80
To find number of students that should be on each float, find highest common factor (H.C.F) of 100 and 80
Write prime factorisation of 100 and 80.
100 = 
× 
80 = 
× 5
So,
H.C.F(100, 80) = × 5 = 4 × 5 = 20
Therefore,
20 students should be on each float
Step-by-step explanation:
2 adult shirts = 36.95 x 2 = 73.9
5 youth shirts = 23.95 × 5 = 119.75
Total = 119.75 + 73.9 = 193.65
