over specific intervals. TO GRAPH PIECEWISE FUNCTIONS: 1. Create a ... function. 2. Plot correct points (if more are plotted than are required points are ... EX 6: During a snowstorm, a meteorologist tracks the amount of accumulating ... the first three hours of the storm, the snow fell at a constant rate of one inch per hour.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
The way to find the line of best fit by estimate is to have about half the points be above and below the line of best fit. In this case Tariq followed the first few points of the data but his estimate would be very off after 10 on the x axis. This would not accurately predict what the next data point could be.
Given:
Original price = 20
reduces selling price by 25% every month it's not sold.
First markdown month:
20 * (100%-25%) = 20 * 75% = 15
Second markdown month
15 * 75% = 11.25
Macy, employee gets a 50% discount off the current price.
11.25 * 50% = 5.625
11.25 - 5.625 = 5.625 or 5.63
The pre-tax price of the shirt for Macy will be $5.63
Answer: B has greater spread than A.
Step-by-step explanation:
Since we have given that
Set A: {38, 12, 23, 48, 55, 16, 18}
Range of A = Highest - Lowest
Range of A = 55 - 12
Range of A = 43
Set B:{44, 13, 24, 12, 56}
Range of B = Highest - Lowest
Range of B = 56 - 12
Range of B = 44
Since Range of B is more than range of A.
Hence, B has greater spread than A.
When the ball will hit the ground, the height will be zero. So we need to replace

with 0 in our equation, and solve for

:


To solve this equation we are going to use the quadratic formula:

.
From our height equation, we can infer that

,

, and

. So lets replace those values in our quadratic formula to find



or


or

Since time cannot be negative,

is the solution of our equation.
We can conclude that the ball will hit the ground after
2.71 seconds.
