Area = 1/2 * 7.2*6.4*sin49= 17.4cm^2

Answer with Step-by-step explanation:

The area of a triangle when one angle a is given is given by:

A=\dfrac{1}{2}\times sina\times (Product\ of\ sides\ adjacent\ to\ angle\ a)

Here a=49 and sides adjacent to angle a are 7.2 and 6.4

A=\dfrac{1}{2}\times sin49\° \times 7.2\times 6.4\\\\A=\dfrac{1}{2}\times 0.75\times 7.2\times 6.4\\\\A=17.4\ cm^2

Hence, Area of given triangle is:

17.4 cm²

As θ increases, the value of cos θ increase, decreases or stays the same?
icang [17]

Answer:

As θ increases, the value of cos θ decreases

Step-by-step explanation:

As as θ increases, the value of cos θ decreases from 1 to -1 in the first two quadrants ( between 0 and 180 degrees). Cos(0) = 1, cos(90) = 0, cos(180) = -1.

On the other hand, as θ increases from 180 to 360 degrees (last two quadrants) the value of cos θ increases from -1 to 1.

Can you please help with this question about exponential equations?
RSB [31]

Since t represents the number of years passed since 2005, in 2005 we have t=0, and in 2015 we have t=10. Let P_J(y),P_D(y) represent the profits of Jones and Davis, respectively, at year y.

We have

P_J(2005) = 10(0.99)^0 = 10,\quad P_J(2015) = 10(0.99)^{10}\approx 9

P_D(2005) = 8(1.01)^0 = 8,\quad P_D(2015) = 8(1.01)^{10}\approx 9

Choosing the best company somehow depends on how much time you can wait: Jones start with a higher value (10 vs 8), but it has a descending trend, because the multiplicative factor 0.99^t goes to zero as t grows.

On the other hand, Davis starts with a smaller value, but 1.01^t tends to infinity as t grows.

So, if you need an immediate result, the most valuable company is Jones, otherwise you're certain can Davis will eventually become bigger.

More precisely, we have

8\cdot 1.01^t = 10\cdot 0.99^t \iff 0.8 = \left(\dfrac{0.99}{1.01}\right)^t \iff t\approx 11

So, after 11 years, Davis will overcome Jones.
