Which expression is equivalent to cot t sec t?

1 answer:

3 0

$\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}
\qquad 
% cosecant
csc(\theta)=\cfrac{1}{sin(\theta)}
\qquad 
% secant
sec(\theta)=\cfrac{1}{cos(\theta)}\\\\
-------------------------------\\\\
cot(t)sec(t)\implies \cfrac{\underline{cos(t)}}{sin(t)}\cdot \cfrac{1}{\underline{cos(t)}}\implies \cfrac{1}{sin(t)}\implies ?$

Find the distance between the two given points. (-6, -5) and (2, 0)

Ipatiy [6.2K]

Answer:

The answer is

<h2> $\sqrt{41} \: \: or \: \: \: 6.403 \: \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{( {x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-6, -5) and (2, 0)

The distance is

$d = \sqrt{ ({ - 6 - 2})^{2} + ({ - 5 - 0})^{2} } \\ = \sqrt{ ({ - 4})^{2} + ({ - 5})^{2} } \\ = \sqrt{16 + 25} \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{41} \: \: or \: \: \: 6.403 \: \: \: units$

Hope this helps you

What is the solution of -4(8-3x)>or=6x-8?

Illusion [34]

Answer:

-4(8-3x)>or =6x-8

Step-by-step explanation:

open d bracket

-32+12x >or = 6x-8

collect like terms

12x-6x >or =-8+32

6x = 24

divide both sides by 6

x= 4

A line is shown in the graph below.

Kay [80]

Answer:

-3/2

Step-by-step explanation:

One can read off the slope of the given line directly from the graph. As x increases by 3, y increases by 2. Thus, the slope of the given line is

m = rise / run = 2 / 3

Any line perpendicular to this given line has a slope which is the negative reciprocal of the slope previously found:

-1 3

Slope of perpendicular line = ------------ = - -----

2/3 2

This matches the first of the given possible answer choices.
