5. Find the square rots of 4i.

Answers

Answer:

$√(4i)=2√(i)$

Step-by-step explanation:

$4i=4√(-1)$

Applying square root

$√(4i)$

$=\sqrt{4√(-1)}$

$=2\sqrt{√(-1)}$

$=2* -1^{(1)/(4)}$

Now,

$i=√(-1)\n\Rightarrow i=-1^{(1)/(2)}$

$\n\Rightarrow 2* -1^{(1)/(4)}=2* i^{(1)/(2)}=2√(i)$

So, $√(4i)=2√(i)$

The table shows the height of a plant as it grows. What equation in point-slope form gives the plant s height at any time? Let y stand for the height of the plant in cm and let x stand for the time in months. Time (months) Plant Height (cm) 3 15 5 25 7 35 9 45

Answers

Here Plant height = 5 * time

To determine the appropriate landing speed of an airplane, the formula D = .1x 2 − 3x + 22 is used, where x is the initial landing speed in feet per second and D is the distance needed in feet. If the landing speed is too fast, the pilot may run out of runway; if the speed is too slow, the plane may stall. What is the appropriate landing speed if the runway is 800 feet long? Show all of your work or explain how you came up with your solution

Answers

$800=0.1x^2-3x+22\n0.1x^2-3x-778=0\n\Delta=(-3)^2-4\cdot0.1\cdot(-778)=9+3112=3121\n√(\Delta)=√(3121)\nx_1=(-(-3)-√(3121))/(2\cdot0.1)=(3-√(3121))/(0.2)=15-5√(3121)\approx-264.3\nx_2=(-(-3)+√(3121))/(2\cdot0.1)=(3+√(3121))/(0.2)=15+5√(3121)\approx294.3$
