Answer:

C. cot theta

Step-by-step explanation:

(csc theta -cot theta )/(sec theta -1)

csc = 1/ sin

cot = cos / sin

sec = 1 / cos

Let x = theta

(1/ sin x -cos x / sin x )/(1/ cos x -1)

Getting a common denominator in the denominator and combining terms

(1- cos x)/ sinx  / ( 1 - cos x) / cos x

(1- cosx)      (1- cosx)

----------- ÷ ------------

sinx            cos x

Copy dot flip

(1- cosx)       cosx

----------- * ------------

sinx            1 -cos x

Cancel like terms

cos x / sin x

cos / sin = cot

cot x

cot theta

Hamster heaven charges an annual fee of $20 plus $2.50 for each day of hamster activities you attend. Hamster fun world charges
GarryVolchara [31]

Answer: I wouldn’t be able to make a linear system right now, but it would be better to use Hamster Fun if it were long-term, and Hamster Heaven if it were short-term.

Step-by-step explanation:

HH (Hamster Heaven) charges 20$ plus one a day, and HF (the other) charges 35 plus one a day, so if you went for 80 days for either one:

HH: 20 + (2.50 x 80) =

20+200: 220

HF: 35 + (1 x 80)= 115

If it were for only a day or two, it would be more efficient to use Hamster Heaven.

What is the solution for 1/2+x=5/4
prohojiy [21]
<span>1/2-(5/4) = x+1/4 // - x+1/4

1/2-x-(5/4)-(1/4) = 0

1/2-x-5/4-1/4 = 0

-x-1 = 0 // + 1

-x = 1 // * -1

x = -1

x = -1

The predicted value of y when x =7 is -8.5

<h3>How to predict the y value?</h3>

Start by drawing the line of best fit through the points

See attachment for the graph.

From the attached graph, we have the following value

y = -8.5 when x = 7

Hence, the predicted value of y when x =7 is -8.5

Relate ratios in right triangles
SIZIF [17.4K]

Answer:

B

Step-by-step explanation:

Cos is the adjacent side over the hypotenuse.  The adjacent side to <E is side ED.  The hypotenuse is side EF.  ED/EF.  They do not go right out and give you this choice, but you see that B says the same thing.
