The velocity of an object is given by the following function defined on a specified interval. Approximate the displacement of th

harkovskaia [24]

Answer:

The displacement of the object on this intervals is 1.33 m.

Step-by-step explanation:

Given that,

The function of velocity is

$v=\dfrac{1}{2t+4}\ m/s$

For 0 ≤ t ≤8 , n = 2

We need to calculate the intervals

Using formula for intervals

For, n = 1

$\Delta x=\dfrac{t_{f}-t_{i}}{n}$

$\Delta x=\dfrac{8-0}{2}$

$\Delta x=4$

So, The intervals are (0,4), (4,8)

We need to calculate the velocity

Using given function

$v=\dfrac{1}{2t+4}$

For first interval (0,4),

Put the value into the formula

$v_{0}=\dfrac{1}{2\times0+4}$

$v_{0}=\dfrac{1}{4}$

For first interval (4,8),

Put the value into the formula

$v_{4}=\dfrac{1}{2\times4+4}$

$v_{4}=\dfrac{1}{12}$

We need to calculate the total displacement

Using formula of displacement

$D=(v_{0}+v_{4})\times(\Delta x)$

Put the value into the formula

$D=(\dfrac{1}{4}+\dfrac{1}{12})\times4$

$D=1.33\ m$

Hence, The displacement of the object on this intervals is 1.33 m.

Find the difference of functions s and r shown below. r(x) = –x² + 3x

Gnesinka [82]

Answer:

(2x+1) -(-x^2+3x)

Step-by-step explanation:

r(x) = –x² + 3x

s(x) = 2x + 1

find the difference of (s-r)(x)

(s- r)(x) = s(x) - r(x)

we are given with s(x) and r(x)

to find the difference we plug both functions

(s- r)(x) = s(x) - r(x)

$(s- r)(x) = s(x) - r(x) = (2x+1) -(-x^2+3x)$

distribute negative sign inside the parenthesis

$2x+1 +x^2 -3x = x^2 -x +1$

(2x+1) -(-x^2+3x) is the way we find difference

blondinia [14]

Step-by-step explanation:

It's simple here's The steps:

*Step 1

-Take your ruler and a pencil and construct a segment of any length on a piece of paper

-Then, you will try to set your compass opening to match the length of segment AB

-Take your compass. Make your sure that the pencil is included in it.

-Put the needle of the compass at endpoint A and adjust your compass so that the tip of your pencil touches endpoint B

*Step 2

-Put the needle of your compass at A and draw an arc

-Put the needle of your compass at B and draw an arc

-The two arcs should meet

*Step 3

-Draw the segments from the two endpoints to the point where the two arcs intersect
