A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by gi
GuDViN [60]

The time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

Given the equation representing the height reached by a rocket as:

y = -16x^2 + 157x + 104

The rocket will hit the ground when y = 0. Substituting y = 0 into the expression to get x;

0 = -16x^2 + 157x + 104\\16x^2 - 157x - 104 = 0\\

On factorizing:

x = 10.43 seconds

Hence the time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

Find all values of c such that 3^2c+1=28*3^c-9. If you find more than one value of c, then list your values in increasing order​
avanturin [10]

3^{2c} + 1 = 28\times3^c - 9 \implies 3^{2c} - 28\times3^c = -10

Complete the square on the left side:

3^{2c} - 28\times3^c = \left(3^{2c}-28\times3^c+14^2\right)-14^2 = \left(3^c-14\right)^2 - 196

Then the equation becomes

\left(3^c-14\right)^2 - 196 = -10 \\\\ \left(3^c-14\right)^2 = 186 \\\\ 3^c - 14 = \pm\sqrt{186} \\\\ 3^c = 14\pm\sqrt{186}

Both 14 + √186 and 14 - √186 are positive numbers, so we can take the logarithm (base 3) of both sides without issue:

\log_3\left(3^c) = c = \log_3\left(14\pm\sqrt{186}\right)

Then in increasing order, the solutions are

<em>c</em> = log₃(14 - √186), <em>c</em> = log₃(14 + √186)
