Answer:

The speed of the boat is 24 kilometers per hour, and the speed of the stream is 2 kilometers per hour.

Step-by-step explanation:

Given that a riverboat travels 52 km downstream in 2 hours, and it travels 66 km upstream in 3 hours, the following calculations must be performed to find the speed of the boat and the speed of the stream:

Downstream = 52/2 = 26

Upstream = 66/3 = 22

Stream = 4/2 = 2

Therefore, the speed of the boat is 24 kilometers per hour, and the speed of the stream is 2 kilometers per hour.

Which expression is equivalent to 2cos^2(x/2)- cos(x)?<br> Edge 2020
olchik [2.2K]

Given:

The expression is

2\cos^2(\dfrac{x}{2})-\cos (x)

To find:

The expression which is equivalent to the given expression.

Solution:

We have,

2\cos^2(\dfrac{x}{2})-\cos (x)

We know that,

\cos x=2\cos^2 (\dfrac{x}{2})-1

Using this formula, the given expression can be written as

2\cos^2(\dfrac{x}{2})-\left(2\cos^2(\dfrac{x}{2})-1\right)

=2\cos^2(\dfrac{x}{2})-2\cos^2(\dfrac{x}{2})+1

=1

Therefore, the given expression is equivalent to 1.

The sum of 5 consecutive integers is 120. what is the third number in this sequence?
guapka [62]

Answer:

The third number in the sequence is 24.

Step-by-step explanation:

Sum of five consecutive numbers is 120.

Let the numbers be represented by x,x+1,x+2,x+3,x+4

So the relevant equation for the sum of the numbers is represented as:

x + (x+1) + (x+2) + (x+3) + (x+4) = 5x + (1+2+3+4) = 5x+10

=> 5x + 10 = 120

=> 5x = 120-10

=> 5x = 110

=> x= 110/5 = 22

So the 5 consecutive numbers are 22, 22+1, 22+2, 22+3 , 22+4

In other words the required numbers are 22,23,24,25,26

The third number in the sequence is 24.
