Answer:
![Area= \frac{17 \sqrt{865} }{4} \: {units}^{2}](https://tex.z-dn.net/?f=Area%3D%20%5Cfrac%7B17%20%5Csqrt%7B865%7D%20%7D%7B4%7D%20%20%5C%3A%20%20%7Bunits%7D%5E%7B2%7D%20)
Step-by-step explanation:
From Pythagoras theorem,
![{h}^{2} = {12}^{2} + { (\frac{17}{2} )}^{2}](https://tex.z-dn.net/?f=%20%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%7B12%7D%5E%7B2%7D%20%20%2B%20%20%20%7B%20%28%5Cfrac%7B17%7D%7B2%7D%20%29%7D%5E%7B2%7D%20%20)
![{h}^{2} = \frac{865}{4}](https://tex.z-dn.net/?f=%7Bh%7D%5E%7B2%7D%20%20%3D%20%20%20%5Cfrac%7B865%7D%7B4%7D%20)

The area of the isosceles triangle is
![Area= \frac{1}{2} bh](https://tex.z-dn.net/?f=Area%3D%20%5Cfrac%7B1%7D%7B2%7D%20bh)
![Area= \frac{1}{2} \times 17 \times \frac{ \sqrt{865} }{2} = \frac{17 \sqrt{865} }{4}](https://tex.z-dn.net/?f=Area%3D%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2017%20%5Ctimes%20%20%5Cfrac%7B%20%5Csqrt%7B865%7D%20%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B17%20%5Csqrt%7B865%7D%20%7D%7B4%7D%20)
Let us say that y = vertical height and z =
hypotenuse <span>
dz/dt = 600
dy/dt = 0 since y (altitude) is constant
sin(θ) = 2/3
Calculating for the angle: θ = arcsin(2/3) = 0.729728 radians
sin(θ) = y/z
z sin(θ) = y
<span>We then differentiate the two sides with respect to time t:
dz/dt sin(θ)+ z cos(θ) dθ/dt = dy/dt
(600) (2/3) + (3) cos (0.729728) dθ/dt = 0
400 + [3 / cos (0.729728) ] dθ/dt = 0
400+ 4.0249 dθ/dt = 0
dθ/dt = -98.38 radians/hour
= -99.38/60 radians / min
= -1.66 radians / min = 2PI - 1.66 radians / min
<span>= 4.62 radians / min (ANSWER)</span></span></span>
Kevin will water his plants on the 15th day. He wont water his plants again in February because there are only 28 days in that month, and even on a leap year, there would still be only 29 days
