Mathematics
1 answer:
shtirl [24]3 years ago
7 0

Answer:

A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.

Step-by-step explanation:

By definition, Acceleration is the rate of change of Velocity of an object.

I.e it is the( final velocity minus initial velocity ) ÷  by the time it took for the velocity to change.

If we observe the choices only one choice gives us all 3 components (final velocity, initial velocity, time taken for velocity to change), which is :

A car's velocity changes from 25 m/s to 20 m/s in 5 seconds.

Simplify the trigonometric expression.
Natasha_Volkova [10]
First we are going to find the common denominator of both fractions. To do that, we are going to multiply their denominators:
(1+sin \alpha )(1-sin \alpha )=1-sin^2 \alpha

Now we can rewrite our expression using the common denominator:
\frac{1-sin \alpha }{1-sin^2 \alpha } + \frac{1+sin \alpha }{1-sin^2 \alpha} = \frac{2}{1-sin^2 \alpha}

Finally, we can use the trig identities: 1-sin^2 \alpha =cos^2 \alpha and sec \alpha = \frac{1}{cos \alpha } to simplify our trig expression:
\frac{2}{cos^2\alpha}=2sec^2 \alpha

We can conclude that the correct answer is the fourth one.
