I recently took a test in my Algebra 1 class. This was on the test (that I most likely failed)and it said something about vertical motion. The problem is below. Try to solve it, please! Thanks!2=-t^2+4+5

Answers

OK.    2 = -t² + 4t + 5

Subtract 2 from each side: 0 = -t² + 4t + 3

Multiply the right side by -1 : 0 = t² - 4t - 3

Unfortunately, this can't be factored. The only other way I know
to find the solutions to a quadratic equation is with the use of the
quadratic formula. When you do that, you get these solutions:

   t = 2 + √7 = about 4.65
and
   t = 2 - √7 = about -0.65 .

If this equation comes from a problem that involves real people throwing
real things into the air and making vertical motion, then you want only the
positive solution.

Any smart people out there, i really suck at these problems... Five times Lauren's age, decreased by 2 is equal to two times Lauren's age, increased by 11. How old is Lauren?

Answers

Set Lauren's age equal to L.

Using what the problem gave us, we can quickly set up an equation:

5L - 2 = 2L

Solving this equation, we get 3L = 2. L = 2/3 Lauren is 2/3 of a year old.

Take it slowly, one step at a time.

First, you need to pick something to call "Lauren's age",
because you don't know what number it is. I have a bright idea !
Let's call Lauren's age ' L ' ! OK ?

Use ' L ' to build the quantities discussed in the question:

Five times Lauren's age . . . . . . . . . . . . . . . . . 5 L
Five times Lauren's age, decreased by 2 . . . 5L - 2

Two times Lauren's age . . . . . . . . . . . . . . . . . 2 L
Two times Lauren's age, increased by 11 . . . 2L + 11

The question says that these 2 quantities are equal,
so write that down:
      5L - 2 = 2L + 11

Add 2 to each side:     5L      = 2L + 13

Subtract 2L from each side: 3L      =   13

Divide each side by 3 : L      =   13/3 or 4 and 1/3 .

That's certainly a weird number, but you can
check it out, and you'll find that it's true:

Lauren's age . . . . . 13/3

Five times Lauren's age . . . . . . . . . . . . . . . . . 65/3
Five times Lauren's age, decreased by 2 . . . 59/3 <===

Two times Lauren's age . . . . . . . . . . . . . . . . . 26/3
Two times Lauren's age, increased by 11 . . . 59/3 <===

Those 2 quantities are equal. So Lauren is 4-1/3 years old, by golly !

She estimates that she uses 18 cases of motor oil a day. Each case has 24 one-quart bottles of motor oil. About how many quarts of oil does Gwen use in a day? A. about 600 B. about 400 C. about 200 D. about 40 Question Resources

Answers

The answer is B.about 400, because if you multiply 18 by 24 you get the answer without rounding, and that answer would be 434; once 434 is rounded to the closest possible answer, you get that the answer, which is, as stated before, B. about 400.

Answer: 60 degrees

Step-by-step explanation:

Answer:60

Step-by-step explanation:When you do 55+5 you get 60. That's because it moves 5 degrees right which adds onto 55. Then you do 180-60 to find the measure of 2. That's 120 and finally you do 180-120 to find the measure of 3, which is 60.

Ms. Hartland bought x number of shirts for the new members of her chorus. The cost for x number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Which equation could be used to find x? A. 3.99(x+12.25) =77.49B. 3.99x + 12.25 =77.49C. 12.25(x+3.99) = 77.49D. 12.25x+3.99= 77.49
