Answer:

m = 1.25d

Step-by-step explanation:

A train is traveling at a constant speed and goes a distance of 7 ½ kilometers or 7.5 km in 6 minutes.

6 min = 7.5 km

1 min = (7.5/6) km/min

= 1.25 km/min

or

In m min, (7.5/6)d is travelled by the train. Hence, the relation between d and  is :

m=\dfrac{7.5d}{6}\\\\m = 1.25d

Hence, this is the required solution.

Factor the algebraic expression below in terms of a single trigonometric function. sin 2x + sin x - 2
Pie

Answer:

The factored form is (sin x +2)(sin x-1)

Step-by-step explanation:

We have been given the trigonometric function \sin^2 x +\sinx-2

We can factor this by AC method. In AC method we multiply the term a and c and then write the middle term b in such a way that the sum/difference is equal to the product 'ac'

Using the method, we can write sinx as 2sinx -sinx

\sin^2 x +2\sinx-\sin x-2

Now, we group the first two terms and the last two terms

(\sin^2 x +2\sinx)+(-\sin x-2)

Now, we take GCF from each group

\sin x(\sin x +2)-1(\sin x+2)

Factor out (sinx+2)

(\sin x +2)(\sin x-1)

Therefore, the factored form is (sin x +2)(sin x-1)
