Find the time it takes for a rocket following the path, h(x) = - 3x2 + 18x, to reach a maximum. In your final answer, include all of your calculations and a verbal explanation of the process that you followed in your solution.

Answer:

The slope would be 1/2.

Step-by-step explanation:

Step one: Subtract 2x from both sides to get, -4y=-2x+18

Step two: Divide -4 from all sides

It is just that simple. Hope this helps. Have an awesome day!!!!!!!

(I) is not necessarily true. Consider the function f(x) = - |x| on the interval [-1, 1]. There's a maximum at x = 0, but f' (0) does not exist.

But both (II) and (III) are true, so the answer is A.

Answer:

t = 0

Step-by-step explanation:

(7t - 2) - (-3t + 1) = -3(1 - 3t)

because you can not do anything inside the parantheses, you distribute. there aren't any numbers on the left side of the parantheses on the left side of the equation so we just imagine the number 1. on the right side of the equation, just distribute normally

[ 1(7t - 2) -1(-3t + 1) = -3(1 - 3t) ]

will be

7t - 2 + 3t - 1 = -3 + 9t

add like terms

10t - 3 = -3 + 9t

subtract 9t from both sides

t - 3 = -3

add 3 to both sides

t = 0

Because to make a scaled copy you have to MULTIPLY or DIVIDE all the lengths of the figure

Answer:

A= 5/7b +8

Step-by-step explanation:

The basic idea is that you can do anything you want (except divide by

zero) to either side of the equation, so long as you do the same thing

to the other side, too.

5/6 * 4 = 20/6

20/6 = 3 2/6 = 3 1/3

Answer:

After the first 3 weeks Jeremiah saved $135. If the situation is proportional:

$135 : 3 = $ 45. It means that he can save $45 for one week.

Therefore an equation is:

s = 45 * w,

where s is the amount saved and w is the number of weeks.

After 8 weeks :

s = 45 * 8 = $360.

Answer:

8 + 3x ≤ 20

Step-by-step explanation:

Given

2 Games = $8

Additional Game = $3

Amount = $20

Required

Determine the inequality that represents the number of games

From the question, we understand that the minimum number of games that can be played is 2.

So, the expression can be:

Cost of 2 games + Cost of additional games ≤ Amount

This gives:

8 + 3 * x ≤ 20

Where x represents the additional number of games

By simplifying the expression, we have:

8 + 3x ≤ 20

Answer:

The probability is [tex]P( X > 12.10 ) =0.0004[/tex]

Step-by-step explanation:

From the question we are told that  

    The mean is  [tex]\mu = 11.95 \ ounce[/tex]

     The  standard deviation is  [tex]\sigma = 0.045 \ ounce[/tex]

 Generally the  probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow is mathematically represented as

      [tex]P( X > 12.10 ) = P( \frac{X - \mu }{\sigma } > \frac{ 12.10 - 11.95}{0.045} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P( X > 12.10 ) = P( Z > 3.33 )[/tex]

From the z table  the area under the normal curve to the right corresponding to  3.33   is

     [tex]P( Z > 3.33 ) = 0.0004[/tex]

=>  [tex]P( X > 12.10 ) =0.0004[/tex]
