The distance from the base of the tree to the tallest would be 14.21 cm

<h3>We have the following data points in this question</h3>

X1 = 8 feet

y1 = 16 feet

x2 = 11 feet

y2 = 9 feet

To proceed with the solution we have to

We have to solve for the shorter tree

\sqrt{(y2 -y1)^2 + (x2-x1)^2} \\\\= \sqrt{9-0^2 + 11-0^2}

<em>= </em>9² + 11²

= √81 +121

= 14.21

<h3>For the taller tree we would have</h3>

√8² + 16²

= √64 +256

= 17.89

Step-by-step explanation:

\frac{( \csc x+1)( \csc  x-1)}{ \csc ^2x} =  \frac{ { \csc }^{2} x - 1}{  \csc^{2} x}  \\ = 1 -   \sin^{2} x =   \cos^{2} x \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

b. Since csc theta = 1/sin theta, we can multiply both sides by sin theta and you will end up with

\cos^{2} \theta  +  \sin^{2} \theta  = 1

which is an identity.

What is 4c minus 7.8 if c is 4
Debora [2.8K]
Here is a substitution problem. By saying c is 4, we can replace anywhere we see c with the number 4.

c = 4

4c - 7.8
= 4(4) - 7.8
= 16 - 7.8
= 8.2

Hope this helps! :)

Determine the total annual fica tax for an annual salary of $38,480.
egoroff_w [7]
The annual FICA (Federal Insurance Contributions Act) tax is composed of two parts: Social Security and Medicare Taxes. On the employee's side, he/she has to shoulder 6.2% of the annual salary for the Social Security Tax, and 1.45% of the annual salary for the Medicare Tax. So in total, FICA takes 7.65% of your annual salary as tax. To calculate the FICA tax to be paid, this is shown below:

$38,480 x 7.65% = $2943.72

Therefore, for an annual salary of $38,480, $2943.72 goes into FICA tax payment.
