Answer:
Step-by-step explanation:
<h3>Given</h3>
- Θ= 168°
- t = 0.28 sec
- r = 3 mm
<h3>To find </h3>
<h3>Solution</h3>
<em>Formula for linear velocity</em>
<u>Converting the angle measure from degrees to radians</u>
- 168° = 168*π/180 = 168*3.14/180 = 2.93
<u>Substituting values</u>
- v = 2.93*3/0.28 mm/sec =
- 31.39 mm/sec =
- 0.03 m/sec rounded to nearest hundredths
Answer:
Step-by-step explanation:
F(x) = 7 - 5x + 7x²
f(-9) = 7 - 5*(-9) + 7*(-9)²
= 7 + 45 + 7*81
= 7 + 45 + 567
= 619
