Now given a rope hanging from the top of a pole. The end lying on the ground is 3 chi long. When tightly stretchedit is 8 chi fr

drek231 [11]

Answer:

Height of the pole = 9.17 chi.

Length of the rope = 12.17 chi.

Step-by-step explanation:

Given that the rope is hanging from the top of a pole having height x chi and the portion of the rope lying on the ground is 3 chi.

So, the length of the rope= x + 3 chi.

Let AB represents the pole in the figure, and one end of the rope is at point A.

When the rope is tightly stretched, let C be the other end of the rope as shown in the triangle.

The length of the rope = AC.

\Rightarrow AC=x+3 chi.

Distance from the bottom of the pole, point A, to the other end of the pole, point B, is 8 chi.

So, BC=8 chi.

As the triangle ABC is a right-angled triangle, so by using Pythagoras theorem,

$AC^2= AB^2+BC^2$

$\Rightarrow (x+3)^2=x^2+8^2$

$\Rightarrow x^2+6x+9=x^2+64$

$\Rightarrow 6x=64-9=55$

$\Rightarrow x=55/6=9.17$ chi.

Hence, the height of the pole, $AB=x=9.17$ chi,

and the length of the rope, $x+3=9.17+3=12.17$ chi.

Please help!! Will mark BRAINLIEST!! Find an equation for the graph sketched below:

Sedbober [7]

The equation for the graph sketched below is $y=-3 \cdot (-\frac{1}{3} )^x$

The given graph is an exponential graph and the standard exponential graph is expressed as $y=ab^x$

a is the y-intercept of the graph

(x, y) is any point on the graph.

Given the following from the graph;

a = -3

(x, y) = (1, 1)

Substitute the point and the y-intercept into the formula to have

$1=-3\cdot b^1\\\b = -\frac{1}{3} \$

Get the required exponential equation:

Recall that $y=ab^x$

$y=-3 \cdot (-\frac{1}{3} )^x$

Hence the equation for the graph sketched below is $y=-3 \cdot (-\frac{1}{3} )^x$
