If cross products are equal the ratios are equal?
Yes, they are.
When you cross multiply two equal ratios the what are equal?
The products.
What does it mean if the cross products of two ratios are not equal?
The ratios are not equal.
Can a proportion be equal if the cross products are not equal?
No. A cross product is just a way of simplifying a proportion. If the cross product aren't equal, it follows logically that the proportion isn't equal.
What are characteristics of an equivelent fraction?
Their cross products are equal.
What is true about the cross products of a proportion?
They're equal
Determine whether the ratios 9 15 and 6 10 form a proportion Justify your answer?
The fractions are proportional and their cross products are equal
When does the magnitude of dot product and cross product of vectors is equal?
If x is the angle between the two vectors then the magnitudes are equal if cos(x) = sin(x). That is, when x = pi/4 radians.
Can A plus B equal zero when A and B have nonzero magnitudes?
If 'A' and 'B' are vectors, and their magnitudes are equal, andtheir directions are opposite, then their vector sum is zero.
When are the magnitudes of two vectors equal to zero?
When they are equal in magnitude but opposite in direction.
Can the sum of the magnitudes of two vectors ever be equal to the magnitudes of the sum of these two vectors?
only if the vectors have the same direction
How are cross products useful in solving a proporton?
The cross products are equal. If there is a variable you can make that variable so it will make the proportion equal. 1/2=x/14 1x14=2x So x=7
