Answer:

Irrational

Step-by-step explanation:

f(x) = 2 {x}^{2}  - 3x - 8 \\ equating \: it \: with \\ f(x) = a {x}^{2}  + bx + c \\ a  =  2 \:  \: b =  - 3 \:  \: c =  - 8 \\  {b}^{2}  - 4ac \\  = ( - 3)^{2}  - 4 \times 2( - 8) \\  = 9 + 64 \\  = 73 \\   \because \: 73 \: is \: not \: a \: perfect \: square \: no \\  \therefore \:  \sqrt{73}  \: is \: irrational

Hence, given function has <u>irrational</u><u> </u>roots.

The water level in a lake decreased by 2 1/4 inches in march and increased by 1 5/8 inches in april. Determine wether the water
mezya [45]

Change in level is given by :

C = increase in level - decrease in level.

Now,

Decrease in level in March is 2 1/4 = 9/4 inches.

Increase in level in April is 1 5/8 = 13/8 inches.

Putting value of these in above equation, we get :

C = 13/8 - 9/4

C = 13/8 - 18/8

C = -5/8 inches

Therefore, the overall level after April will decrease by 5/8 inches.

Hence, option 4. is correct.

1044 fans join a club in the first month after the first month nine new members are allowed to join each month how many members
laiz [17]

Answer:

Total number of members in month 34 is 1341 members.

Step-by-step explanation:

We have given,

Number of fans join a club in first month = 1044

And after the first month nine new members are allowed to join each month.

After first month , Let the number of club members in x months will be given as:

Number of members = 1044 + 9x

We need to find number of members in month 34.

So for first month we already had 1044 members, that mean for remaining 33 months we need to calculate members.

i.e total number of members in month 34 = 1044 + (33×9 )     , {Since x = 33 here}  

OR total number of members in month 34 = 1044 + 297  = 1341 members
