Answer:
w·v = -87
Step-by-step explanation:
The projection of a vector on another vector is given by the dot product between the vectors.
Thus, you calculate the dot product between w and v:
So, the projection of w on v is -87

Answer:
PQ =
Step-by-step explanation:
given MQR = 60, PQR = 75
MQP = 75 -60= 15
WE KNOW THAT MQR +QRM +QMR = 180
MPQ = MQP AS ANGLE OPPOSITE TO EQUAL SIDES ARE EQUAL
THEREFORE QMR = 90 - 60 = 30
therefore PQM = 75 - 60 = 15
PM = PQ because M is the mid point
therefore PR = PM +
PR =
PQ =
Answer:
The slope is 2.
Step-by-step explanation:
The given line has equation: .
This is a linear equation in .
The slope is the coefficient of the independent variable .
The coefficient of in
is 2.
Therefore the slope is 2.
Alternatively, is of the form
, where
is the slope.
