Answer:

=10.24

Step-by-step explanation:

500(1+0.07)^x = 1000

divide both sides by 500

(500(1+0.07)^x)/500 = 1000/500

(1+0.07)^x = 2

1.07^x = 2

convert your it to log format:

x = log(107/100)2

x = 10.24

A guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.

frutty [35]

Answer:

The length of the wire is 76.19 m.

Step-by-step explanation:

It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.

It means base of the right angled triangle is 40 m.

The wire makes an angle of 58deg 20min with the ground.

1 degree = 60 min

Using this conversion convert the given angle in degree.

$58^{\circ}20'=58^{\circ}\frac{20}{60}^{\circ}=58\frac{1}{3}^{\circ}=\frac{175}{3}^{\circ}$

In a right angled triangle

$\cos \theta=\frac{adjacent}{hypotenuse}$

$\cos (\frac{175}{3}^{\circ})=\frac{40}{hypotenuse}$

$0.525=\frac{40}{hypotenuse}$

$hypotenuse=\frac{40}{0.525}$

$hypotenuse=76.190$

Therefore the length of the wire is 76.19 m.
