motikmotik

Answer:

1. -7/8

2.-9/14

3. 9/14

4. 7/8

2. what is the product of -2/7 and -3/7?

1. -7/8

2.-6/49

3. 6/49

4. 7/8

How do the expressions 72÷ 9 and -72÷ (-9) compare when they are evaluated?

1. They have different values and are different signs.

2. They have different values but are the same sign.

3. They have the same value but are different signs.

4. They have the same value and the same sign.

Step-by-step explanation:

Multiplying fractions: multiply numerators and multiply denominators

1. 3/4 X -6/7 = -18/28 = -9/14

2. -2/7 X -3/7 = 6/49

3. 4 because 72/9 is 8. -72/-9 is 8. Two negatives makes a positive when multiplying and dividing.

Find a vector equation and parametric equations for the line The line through the point (2, 2.4, 3.5) and parallel to the vector

BartSMP [9]

Answer:

The vector equation

$r = (2 + 3t)i+ (2.4 + 2t)j+ (3.5 - t)k$

The parametric equation

$x = 2 + 3t\\y = 2.4 + 2t\\z = 3.5-t$

Step-by-step explanation:

Given

$Point = (2,2.4,3.5)$

$Vector = 3i + 2j - k$

Required

The vector equation

First, we calculate the position vector of the point.

This is represented as:

$r_0 = 2i + 2.4j + 3.5k$

The vector equation is then calculated as:

$r = r_o + t * Vector$

$r = 2i + 2.4j + 3.5k + t * (3i + 2j - k)$

Open bracket

$r = 2i + 2.4j + 3.5k + 3ti + 2tj - tk$

Collect like terms

$r = 2i + 3ti+ 2.4j + 2tj+ 3.5k - tk$

Factorize

$r = (2 + 3t)i+ (2.4 + 2t)j+ (3.5 - t)k$

The parametric equation is represented as:

$x = x_0 + at\\y = y_0 + bt\\z = z_0 + ct$

Where

$r = (x_0 + at)i +(y_0 + bt)j+(z_0 + ct)k$

By comparison:

$x = 2 + 3t\\y = 2.4 + 2t\\z = 3.5-t$
