HELP ASAP PLEASE???!!!

Answers

Answer 1

Answer:

You need to start by multiply all terms by (x-2)(x+1) and cancel

x(x+1)(x-1)(x-2)=-1(x-2)(x+1)

2x²-2x+2=-x²+x+2

Now you need to subtract -x²+x+2

2x²-2x+2-(-x²+x+2)=-x²+x+2-(-x²+x+2)

3x²-3x=0

Now factorize

3x(x-1)=0

3x=0 or x-1=0

x= 0 or x=1

I hope that's help and good luck :0

90. The pharmaceutical abbreviation "bid" means _____________________. a. once a day b. twice a day c. once a week d. twice a week

Answers

Answer:

The pharmaceutical abbreviation "bid" means "twice a day." In medical terminology, "bid" stands for "bis in die," which is Latin for "twice a day." It indicates that a medication should be taken two times within a 24-hour period, typically with an interval of approximately 12 hours between doses.

Step-by-step explanation:

Understanding pharmaceutical abbreviations is crucial for proper medication administration and adherence to prescribed dosing schedules. In this case, knowing that "bid" means "twice a day" helps ensure that patients take their medication as directed by their healthcare provider.

What is the simplified form of x minus 5 over x squared minus 3x minus 10 ⋅ x plus 4 over x squared plus x minus 12? (6 points)

Answers

Answer: Our simplified form will be

$(1)/((x+2)(x-3))$

Step-by-step explanation:

Since we have given that

$(x-5)/(x^2-3x-10)* (x+4)/(x^2+x-12)$

So, first we split the middle term of the denominator ,

$x^2-3x-10=0\n\n=x^2-5x+2x-10\n\n=x(x-5)+2(x-5)\n\n=(x-5)(x+2)$

Similarly,

$x^2+x-12=0\n\nx^2+4x-3x-12=0\n\nx(x+4)-3(x+4)=0\n\n(x+4)(x-3)=0$

Now, we put in our expression above:

$(x-5)/((x-5)(x+2))* (x+4)/((x-3)(x+4))\n\n=(1)/(x+2)* (1)/(x-3)\n\n=(1)/((x+2)(x-3))$

Hence, our simplified form will be

$(1)/((x+2)(x-3))$

Step 1 is to factor everything!

After factoring you will get:

x-5 over (x+2)(x+5) times x+4 over (x-3)(x+4)

Step 2 is to remove the duplicate factors!
Remove x+4 and x+5

x-5 over (x+2)(x-5) times 1 over x-3 = 1 over x+2 times 1 over x-3

Step 3 is to multiply the numerators and the denominators.

End result is 1 over (x+2)(x-3)

A desk is on sale for 34% off. The sale price is $363 .What is the regular price? I tried this problem so many times but I keep getting it wrong.. :(

Answers

The answer is the regular price is $486.42

Answer:

The answer to this is $550 for regular price. You take 100% -34% = 66% left. 363/66= 5.5 times 100 = 550

Simplify the expressions by combining like terms1. 6n^2 - 2n - 3 + 5n^2 - 9n - 6
2. 8c^2 - c + 3 + 2c^2-c + 2

Answers

Hey!

---------------------------------------------------------

Question #1:

= 6n^2 - 2n - 3 + 5n^2 - 9n - 6

= 6n^2 + (-2n) + (-3) + 5n^2 + (-9n) + (-6)

= (6n^2 + 5n^2) + (-2n + -9n) + (-3 + -6)

= (11n^2) + (-11n) + (-9)

Answer: 11n² + (-11n) + (-9)

---------------------------------------------------------

Question #2:

= 8c^2 - c + 3 + 2c^2 - c + 2

= 8c^2 + (-c) + 3 + 2c^2 + (-c) + 2

= (8c^2 + 2c^2) + (-c + -c) + (3 + 2)

= (10c^2) + (-2c) + (5)

Answer: 10c² + (-2c) + 5

---------------------------------------------------------

Hope This Helped! Good Luck!

Answer:

1. 11n^2-11n-9

2. 10c^2-2c+5

Step-by-step explanation:

1. 6n^2+5n^2 = 11n^2

-2n-9n = -11n

-3-6=-9

2. 8c^2+2c^2 = 10c^2

-c-c= -2c

3+2=5

Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet per second. Assume the starting height of the ball is 0 feet. Approximately what maximum height does the soccer ball reach?0.8 ft

1.6 ft

9.8 ft

19.6 ft

Approximately, how long does it take until the soccer ball hits the ground again?

0.6 sec

0.8 sec

1.6 secs

2.8 secs

Answers

Answer:

Maximum height=9.8 ft and Time taken by soccer ball will be 0.8 secs

Step-by-step explanation:

Since, the ball kicked will take the motion of projectile, therefore using the equation: h(t)= $at^(2) +vt+d$ , where h(t) is the height of the soccer ball, a is the acceleration whose value is -16 ft/sec^2 and v= 35 feet and d is the starting height which is equal to zero.
