.08 x   + .06 (2000-x) = 135     solve for x , the amount at 8%     then 6% amount = 2000-x

h(t) = 25 ft

25 = 45-7t-6t^2

0 = 20 - 7t - 6t^2    Use quadratic formula to find t = 1.33 sec

The stone has to travel down 150 m to strike

x = 1/2 at^2  

150 = 1/2 (9.81)t^2      t = 5.53 sec

Then the sound waves have to travel 150 m

150 m / 343 m/s = .437 s

5.53 + .437 = 5.96  sec

Let  X  be the original number.

Subtract that number from 1   --->   1 - X

Multiply this result by 4:          --->   4(1 - X)

Add half the difference when 6 is subtracted from 10 times the original number:

                                               --->   4(1 - X) + ½(10X - 6)

Final result:                            --->   4 - 4X + 5X - 3   =   X + 1

a)  Let  X = 3:  --->   X + 1  =  4

b)  To find the original number from the answer:  Subtract 1.

Determine and state the price of a drink, to the nearest cent.

Determine and state the price of a bag of popcorn, to the nearest cent.

6(x+2) - 2x = 152    (we'll see if this results in odd integers....if not we will modify the equation)

6x+12-2x

4x = 140

x=35

35    and 37

none of those are right but thanks anyway

1. There are 18*17*16 ways to choose the three seats, if people can be adjacent.  We must subtract the cases where there are two people adjacent, which is 18*13*6.  So the number of ways is 18*17*16 - 18*13*6 = 3492.

2. 1200 factors as 3*4*4*5*5.  The number of rearrangements is 5!/(2!*2!) = 30.

Here is the pic.

Start out by graphing all of the points ....   then bring your graph back here for further help....  

This is a bowl shaped parabola with zeroes at -4  and 2  .....in between it is less than zero

n = -3    -2   -1   0   1

The third angle in an isosceles triangle is 10 more than 3 times as large as each of the two base angles. Find the measure of each angle.

Der dritte Winkel in einem gleichschenkligen Dreieck ist 10 mehr als dreimal so groß wie jeder der beiden Basiswinkel. Finden Sie das Maß für jeden Winkel.

Hello Guest!

\(2\alpha+\gamma=180^0\\ 2\alpha+3\alpha+10^0=180^0\\ 5\alpha=170^0 \)

\(\alpha=\beta=34^0\)

\(\gamma=180^0-2\alpha\)

\(\gamma=112^0\)

  !

The angles sum to 180^o

^{x  +  x   +  (10 +3x) = 180     solve for x the two smaller angles then the laregest = 10 + 3x}

(ar^b)^3=125r^24

whats a and b?, they are both positive

Mmm lets see if I can make this question make some sense....

1. Explain the transformation that takes place from the parent form of this function Graph the function f(x) = ^3√ x-2.

Do you mean     \(f(x)=\sqrt[3]{x}-2\)     ??

Do you intend     \(g(x)=\sqrt[3]{x}\)      to be the parent function?

If so then the parent graph has been translated down by 2 units.

If no one gets the right answer why didn't you say so, on the original post.

AND also say why you believe it is not the right answer.

Is it because you are an ungrateful, uncommunicative brat?

Solution sketched out as follows:

(Strictly, this proves that if the roots are in arithmetic sequence then the condition is true.)

No he is not kidding you he is the same m***n that we have both been dealing with.

Thanks EP

I answered this question before.  I even displayed the pic for him/her.

I finally get it.

Thanks Alan.   

Look at the point where the curve intersects the y axis (at y = 3).  Now move along to the right until the curve intersects the point y = 3 again for the second time I.e. so the curve has the same slope as at y = 0. The number of x units between these two points represents the period.

The domain (x values) of both functions is -infinity to +infinity.

The range (y values) of the first function is from -1 to 3 since cosine ranges from -1 to 1.

Similarly, the range of the second function is from -3 to 3 since sine also ranges from -1 to 1.
