Answer is The circumference is found by multiplying pi by the diameter.
Answer: check the attached graph for the answer
Step-by-step explanation: Please find the attached file for the solution
Given:
Item time
shirt 26.1 seconds
sweater 24.3 seconds
pants 32.8 seconds
scarf 18.2 seconds
Add up all the time in seconds:
26.1 + 24.3 + 32.8 + 18.2 = 101.4
divide the sum by the 4 items:
101.4 / 4 = 25.35 seconds
The average time Janette took to fold and put away all 4 items is 25.35 seconds.
You shouldn't need a calculator for this. The quadratic equation is written in standard form.
ax^2 + bx + c = 0
You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.
(-7)^2 - 4(2)(-8)
49 - 4(-16)
49 - (-64)
49 + 64
113
Best of Luck!
