Since it is given that one hole = 0,79m^2
0,79=3,142 x radius^2
radius^2=3,142 Divided by 0,79
radius=Square Root of 3.97721512
radius=1.994295662
=1.99m^2 (3 Significant Figures)

Evaluate it..........

trasher [3.6K]

Answer:

the answer is $\frac{1}{41} (23x-2ln(5sinx+4cosx))$

Step-by-step explanation:

$\int {\frac{3sinx+2cosx}{5sinx+4cosx} } \, dx$

here,

a=3, b=2, c=5, d=4

$M=\frac{ac+bd}{c^2+d^2 }=\frac{3*5+2*4}{5^2+4^2}=\frac{23}{41}$

$N=\frac{bc-ad}{c^2+d^2 }=\frac{2*5-3*4}{5^2+4^2}=\frac{-2}{41}$

$\int {\frac{3sinx+2cosx}{5sinx+4cosx} } \, dx=\int{\frac{\frac{23}{41}(5sinx+4cosx)-\frac{2}{41}(5cosx-4sinx) }{5sinx+4cosx} }\,dx$

$=\frac{23}{41}\int\, dx -\frac{2}{41} \int{\frac{5cosx-4sinx}{5sinx+4cosx} }\, dx$

$=\frac{1}{41} (23x-2ln(5sinx+4cosx))$

BD and AC are chords that intersect at point Y.

Sindrei [870]

Answer:

4 units

Step-by-step explanation:

The complete question is

BD and AC are chords that intersect at point Y. A circle is shown. Chords B D and A C intersect at point Y. The length of B Y is 3, the length of Y D is 8, the length of A Y is x, and the length of Y C is 6. What is the length of line segment AY?

The picture of the question in the attached figure

we know that

The Intersecting Chord Theorem states that: When two chords intersect each other inside a circle,the products of their segments are equal.

In this problem

$(BY)(YD)=(AY)(YC)$
