Answer:

\sin 253.740^{\textdegree} = -\frac{24}{25} = -0.960

\cos 253.740^{\textdegree} = -\frac{7}{25} = -0.280

\tan 253.340^{\textdegree} = \frac{24}{7} =  3.429

Step-by-step explanation:

The point is in the 3rd Quadrant of the Cartesian Plane. Therefore, angle must be between 180° and 270° with respect to the horizontal.

The angle is:

\theta = 180^{\textdegree}+\tan^{-1}\left(\frac{24}{7} \right)

\theta \approx 253.740^{\textdegree}

The values of the trigonometrical functions are computed below:

\sin 253.740^{\textdegree} = -\frac{24}{25} = -0.960

\cos 253.740^{\textdegree} = -\frac{7}{25} = -0.280

\tan 253.340^{\textdegree} = \frac{24}{7} =  3.429

Point T has coordinates (10,20). To calculate the coordinates of point T′ in the image,
Hatshy [7]

Answer: T'(18,36)

Step-by-step explanation:

For this exercise it is important to know the definition of "Dilation".

 A Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure before the transformation) have the same shape but have different sizes.

If the Dilation is centered at the origin, and knowing the scale factor of \frac{9}{5}, you need to multiply each coordinate of the point T by the scale factor in order to find the coordinates of the Image T'.

Knowing that the point T has the following coordinates:

T(10,20)

You get that the coordinates of the Image T' are the shown below:

T'=(\frac{9}{5}*10,\frac{9}{5}*20)\\\\T'=(18,36)

In the year 2003, a company made $6.8 million in profit. For each consecutive year after that, their profit increased by 13%. Ho
LenKa [72]

Answer:

$7.7 million

Step-by-step explanation:

Given: $6.8 million profit made by company.

           13% increase in profit every year.

Now, finding the company´s profit in the year of 2006.

As we know there is 13% increase in profit.

∴ Profit increase= \frac{13}{100} \times 6.8= \$ 0.884

Next adding company´s profit with increase in profit to get profit in the year 2006.

∴ 6.8+0.884= \$ 7.684 ≅ $7.7

The company´s profit in the year 2006 is $7.7 million.
