This Proof Shows The First Five Steps For Verifying Cot^2 (x/2)= Cos X+1/cos C-1 Use The Drop Down Boxes

Answers

Answer 1

Answer:

1. Tangent Half-angle identity

2. 1 + cos x

3. 1 - cos x

Step-by-step explanation:

Just answered the question on edge

Answer 2

The proof shows the first five steps for verifying cot^2 (x/2)= cos x+1/cos x-1 The drop-down box to complete the steps of the proof will be the taking square root of the fraction.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between the sides and angles of a right-angle triangle and the trigonometric ratio are defined as the ratio of the pair of a right-angled triangle.

The first five steps for the following proof are,

Taking LHS

[tex]\rm = cot^2 \frac{x}{2}[/tex]

As we know,

cotx=1/tanx

[tex]\rm = \frac{1}{tan^2\frac{x}{2} } \\\\ = \frac{1}{\sqrt{(\frac{1-cosx}{1+cosx})^2 } } \\\\ =\frac{1}{\frac{1-cosx}{1+cosx} }[/tex]

As the left-hand side term is equal to the right-hand side term the proof and its steps are correct.

Thus, the proof shows the first five steps for verifying cot^2 (x/2)= cos x+1/cos x-1 The drop-down box to complete the steps of the proof will be the taking square root of the fraction.

Bill and John competed in the “Shot Put" event in their school's track
meet. Bill threw the shot 21 feet and 6 inches, while John threw the
shot 17 feet and 4 inches. How much greater was Bill's throw than
John's?

Answers

Answer:

4 feet and 2 inches

Step-by-step explanation:

First, find the difference between the number of feet in their throws:

21 - 17

= 4 feet

Since Bill's throw had 6 inches while John had 4 inches, subtract 2 inches from the 4 feet that we calculated earlier.

This gets us 4 feet and 2 inches, since there are 12 inches in a foot.

So, Bill's throw was 4 feet and 2 inches greater than John's.

An airplane travels at a constant speed of 320 miles per hour. How far, in miles, will the airplane travel in 15 minutes?

Answers

Answer:

80 miles.

Step-by-step explanation:

If it is traveling at 320 miles per hour, and its asking how much its traveled in 15 minutes you do this:

Since 15 minutes is 1/4 of an hour, you take 1/4 of how fast they are traveling at mph, which in this case is 320 mph.

320/4=80

The airplane will travel 80 miles in 15 minutes.

What is Distance?

The length along a line or line segment between two points on the line or line segment.

we need to use the formula of distance.

distance = speed × time

Since the speed of the airplane is 320 miles per hour, we need to convert 15 minutes to hours:

15 minutes = 15/60 = 0.25 hours

Now we can substitute the values into the formula:

distance = speed × time

distance = 320 × 0.25

distance = 80

Therefore, the airplane will travel 80 miles in 15 minutes.

Write a linear function f with f(5)=7 and F(-2)=0.

Answers

Answer:

f(x)=x+2

Step-by-step explanation:

Slope= (7-0)/(5-(-2)) = 7/7 = 1

Y-intercept= 2

substitute the slope, 1, for m and the y-intercept, 2, for b to get:

f(x)=x+2

hope this helps!

The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2

f(5) = 7

This means when x = 5 , y = 7

(5, 7)

f(-2) = 0

(-2, 0)

This implies when x = -2 , y = 0

Using the linear function formula,

y = mx + b

where

m = slope

b = y-intercept

Therefore, the function can be represented as follows:

m = 0 - 7 / -2 - 5 = -7 / -7 = 1

Therefore,

y = x + b

0 = -2 + b

b = 2

The function in relation to x can be represented as follows:

f(x) = x + 2
