How do you do,
csc2x-cot2x = tanx

Answers

Answer 1

Answer: $csc2x-cot2x=tanx \n \n ((1)/(2)cscxsecx) -( (cotx-tanx)/(2) )=tanx \n \n ((cscxsecx)/(2)) -( (cotx-tanx)/(2) )=tanx \n \n (( (1)/(sinx) (1)/(cosx) )/(2)) -( (cotx-tanx)/(2) )=tanx \n \n ((1)/(2(sinxcosx))) -( (cotx-tanx)/(2) )=tanx \n \n ((1)/(2(sinxcosx))) -( ((sinxcosx)*cotx-tanx)/(2*(sinxcosx)) )=tanx \n \n (1-(cos^2x-sin^2x))/(2(sinxcosx)) =tanx \n \n (1-cos^2+sin^2x)/(2(sinxcosx))=tanx$

$(sin^2x+sin^2x)/(2(sinxcosx)) =tanx \n \n (1-cos2x)/(sin2x) =tanx \n \n (sin2x)/(cos2x+1)=tanx \n \n tanx=tanx$

The lengths of the sides of a triangle are 7. and 10. If the length of the longest side of a similar triangle is 25. what is the length of the shortest side of this triangle?

Answers

Answer: 17.5

Step-by-step explanation:

7:10 = x:25

times both sides by 25

25(7/10) =x

than solve for x

X = 25 × (7/10)

X = 17.5

Marc can run 2 miles in 16 minutes. At this rate, how long will it take Marc to run 5 miles? A) 8 minutes
B) 30 minutes
C) 40 minutes

It will take him 40 minutes to run 5 mile.

D) 40 minutes

Answer:

C) 40 minutes

Step-by-step explanation:

It takes Marcus 8 minutes to run a mile. In 40 minutes, Marcus would have ran 5 miles.

1 mile = 8 minutes

5 miles x 8 minutes = 40 minutes to run five miles

Andre bought a new bag of cat food. The next day, he opened it to his cat. The graph shows how many ounces was left in the bag on the days after it was bought. How many ounces of food were in the bag 24 days after Andre bought it?

Answers

16 ounces of cat food was in the bag, on 24th day

Given : The y axis represents dependent variable ie the 'ounces of cat food' , and x axis represents independent variable ie 'days since bag was bought'

To find : Value of y ie ounces of food - on a particular value of x ie days since bag bought , we draw a straight vertical line from value of x to the curve & correspond it to y axis.

From x = 24, if we draw a straight vertical line to the graph - it touches the point ( x,y ) = (24, 16). Extending it further to y axis, we get value of y ie 'ounces of food' = 16

Answer:

There were 16 ounces of Cat Food after 24 days.

Step-by-step explanation:

From the graph attached,

For an ordered pair (x, y) lying on the graph,

x-coordinate represents the number of days since bag was bought and y- coordinate represents the ounces of cat food required.

Now the value x = 24 on x-axis shows the number of days since the bag was bought.

For x = 24, ounces of cat food in the bag ( y ) = 16 ounce

Therefore, 16 ounces of Cat Food were in the bag after 24 days since it was bought.
