Answer:

195 ft

Step-by-step explanation:

The relationship between the horizontal distance, angle, and vertical height is given by ...

Tan = Opposite/Adjacent

Referring to the attached diagram, we have ...

tan(16°) = BT/MB

tan(25°) = BK/MB

Solving for BT and BK, we can describe their difference as ...

BT = MB·tan(16°)

BK = MB·tan(25°)

BK -BT = 35 = MB(tan(25°) -tan(16°))

Dividing by the coefficient of MB gives ...

MB = 35/(tan(25°) -tan(16°)) = 35/0.179562

MB = 195 . . . feet

Marcos is standing 195 feet from the base of the tree.

Characteristic equation:

$r^2+4r-5=(r+5)(r-1)=0\implies r=-5,r=1$

$\implies y_c=C_1e^{-5x}+C_2e^x$

Given that $y(0)=0$ and $y\left(\dfrac\pi2\right)=1$ , you have

$\begin{cases}0=C_1+C_2\\1=C_1e^{-5\pi/2}+C_2e^{\pi/2}\end{cases}\implies C_1=\dfrac{e^{5\pi/2}}{1-e^{3\pi}},C_2=-\dfrac{e^{5\pi/2}}{1-e^{3\pi}}$

so that the particular solution is

$y=\dfrac{e^{5\pi/2}}{1-e^{3\pi}}(e^{-5x}-e^x)$

A farmer divided his field in three parts

MatroZZZ [7]

Answer:

a)Rice => 1/4

b) Vegetables => 1/4

Step-by-step explanation:

Lets say the farmers field was in a square shape. Now divide this square into 4 parts.

Now, each part is 1/4

So, half of his field is for wheat cultivation, i.e., 1/4 + 1/4 = 2/4 = 1/2

So, the other half is for rice and vegetables

2 vegetables have to be grown on the other half

So,

Fraction of field required for growing rice = 1/4

Fraction of field required for growing vegetables = 1/4
