kendra and her horse completed the barrel racing in 15.839 seconds. what is the number rounded to the nearest tenth?

1 answer:

6 0

To round to the nearest tenth, you would want just one number after the decimal point. You would take the number 15.839 and use that nine to round the 3 to a 4. Since four can not round 8 up to anything, your final answer will be "15.8".

Alex

Answer with Step-by-step explanation:

We are given that

Radius of circle=r

Total distance traveled =s

Time=t

Central angle= $\theta$ rad

We know that

Linear speed,v= $\frac{distance}{time}$

Using the formula

Therefore, v= $\frac{s}{t}$

Angular speed, $\omega=\frac{Angular\;displacement}{time}$

By using the formula

$\omega=\frac{\theta}{t}$ rad/s

Which of the following is the result of the equation below after completing the square and factoring? x^2-4x+2=10

Answer:

B. (x-2)^2=12

Step-by-step explanation:

The constant that completes the square is the square of half the coefficient of the x-term. That value is (-4/2)^2 = 4.

There is already a constant of 2 on the left side of the equal sign, so we need to add 2 to both sides to bring that constant value up to 4.

x^2 -4x +2 = 10 . . . . . . . given

x^2 -4x +2 +2 = 10 +2 . . . . complete the square (add 2 to both sides)

(x -2)^2 = 12 . . . . . . . . . write as a square

The range is all positive values...

R{y | y>0}

Range > "Y" such that y is greater than 0
