Answer:
(81 -20.25π) cm²
Step-by-step explanation:
The area of the 9 cm square is ...
(9 cm)² = 81 cm²
The area of the 9 cm circle is ...
(π/4)(9 cm)² = 20.25π cm²
The blue shaded region is the difference of these areas, so is ...
shaded area = (81 -20.25π) cm²
Answer:
0.448 seconds
Step-by-step explanation:
d = -16t² -4t + 412
find t when d = 407
substituting d = 407 into the equation:
407 = -16t² -4t + 412 (subtract 407 from both sides)
-16t² -4t + 412 - 407 = 0
-16t² -4t + 5 = 0 (multiply both sides by -1)
16t² + 4t - 5 = 0
solving using your method of choice (i.e completing the square or using the quadratic equation), you will end up with
t = (-1/8) (1 + √21)= -0.70 seconds (not possible because time cannot be negative)
or
t = (-1/8) (1 -√21) = 0.448 seconds (answer)
