Answer:

cosecα=-\sqrt{1+cot^{2}\alpha  }

Step-by-step explanation:

Write the first trigonometric function in terms of the second for theta in the given quadrant:

csc(theta), cot(theta); theta in quadrant IV

csc(theta) = ?

from trigonometric identity , we know that

cosec^{2} \alpha =1+cot^{2}\alpha  \\cosec\alpha ==+/-\sqrt{1+cot^{2}\alpha  }

since cosecα is negative in the fourth quadrant , we can solve it as thus

cosecα=-\sqrt{1+cot^{2}\alpha  }

i have only used alpha in place of theta, aside from that ,the answer is thus the above

In quadrant IV, we have
\csc\theta
and
\cot\theta

We can use the identity
\csc^{2} \theta=1+\cot^{2} \theta
\csc\theta=\pm\sqrt{1+\cot^{2} \theta}
Since \csc\theta, we get
\csc\theta=-\sqrt{1+\cot^{2} \theta}

A rectangle with dimensions of 3 units by 7 units is enlarged by a scale factor of 1.1. By what percent does it’s area increase?
Ratling [72]

Answer:

21\%

Step-by-step explanation:

Original dimensions of the rectangle

l=7\ \text{units}

w=3\ \text{units}

Area of the rectangle

A=7\times 3=21\ \text{units}^2

Scale factor = 1.1

New dimensions

l'=7\times 1.1=7.7\ \text{units}

w'=3\times 1.1=3.3\ \text{units}

The new area of the rectangle

A'=7.7\times 3.3=25.41\ \text{units}^2

Percentage change is given by

\dfrac{A'-A}{A}\times 100\\ =\dfrac{25.41-21}{21}\times 100=21\%

The percentage by which the area of the rectangle increases is 21\%.
