7/8-1/5
35/40-8/40=27/40
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)
3/4
Write the proportion formula like this: P(event) For this problem you would write it like this: P(pick red) Since there are 4 blocks (two red and two blue) there is a 1/2 chance that you would pull out a red block.
Hope this helps!

It is more than one I think because it becomes -1 over -12 WITHOUT the -power and then add the power and it becomes positive. Make the power positive and it will become negative making it less than 1.
Answer:
Step-by-step explanation:
3x - 2y = 18
x -int
3x - 2(0) = 18
3x = 18
x = 6
(6,0)
3(0) - 2y = 18
-2y = 18
y = -9
(0, -9)
