Molly runs each morning once around a circular path in her neighborhood. if the diameter of the path is 1.4 miles, how far does
Anastaziya [24]
To work out the distance of the path, you need to find out the circumference.
Formula for circumference = pi multiplied by the diameter

So you simply do:
pi multiplied by 1.4 miles

And you should get:
4.39822971503... miles

Simply round the result to an appropriate value (e.g. 3 decimal places).

Answer: 4.398 miles (to 3dp)
Hope the answer helps :)

Prove the following trigonometric identities (secx+tanx)(1-sinx/cosx)=1
miss Akunina [59]

Answer:

Below.

Step-by-step explanation:

Convert  to sin's and cos's:-

(secx + tanx)(1-sinx)/cosx)

= ( 1/ cos x + sinx / cos x) * ( 1 - sin x )/ cos x)

=  (1 + sin x) / cos x) *  ( 1 - sin x ) / cos x

= (1 - sin^2 x) / cos^2 x

But 1 - sin^2 x = cos^2 x

so we have

cos^2 x / cos^2 x  which = 1.
