Evaluate the dot product of (2,4) and (1,2)

Mathematics

Aleksandr [31]3 years ago

ANSWER

The dot product is 10.

EXPLANATION

The given vectors are (2,4) and (1,2).

If we have the vectors

u=(a,b) and v=(c,d)

Then the dot product of the two vectors is given by

u \bullet \: v = ac + bd

This implies that,

(2,4)  \bullet(1,2) = 2 \times 1 + 4 \times 2

This simplifies to;

(2,4)  \bullet(1,2) = 2  + 8 = 10

The staff at Larry's Lawns spends their workday mowing lawns, raking, and bagging leaves. They work an average of nine hours per
Katyanochek1 [597]
For this case what we can do is the following rule of three:
 6 hours ---> 36 bags.
 x ------------> 1 bag
 Clearing the value of x we have:
 x = (1/36) * (6)
 x = 6/36
 x = 1/6 hours
 Answer:
 Assuming the bags are filled at a constant rate, the average time it takes to fill one bag of leaves is:
 x = 1/6 hours

A transformation of ΔDEF results in ΔD'E'F'.
sladkih [1.3K]

Answer:

Rotation

Step-by-step explanation:

A transformation of a triangle can be either dilation or reflection or rotation or a translation.

Dilation happens when a symmetric figure is formed with scale factor other than 1.  But here both triangles have same side length.  Hence no dilation

Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on  a line.  Hence no reflection

Rotation is keeping the same shape but rotating through a certain angle.  Here DEF is rotated without disturbing its shape or size through a certain angle. Hence rotation is right

Translation is not right because there is no vertical or horizontal shift to get new triangle.
