Answer:
No
Step-by-step explanation:
A 5x8 matrix 
represents a linear transformation between the vector space 
and 
. Remeber that the columns of generate the image of the linear transformation, which is a vector subspace of . Therefore, 
, which is the dimension of the the total space.
the parallel line is 2x+5y+15=0.
Step-by-step explanation:
ok I hope it will work
soo,
Solution
given,
given parallel line 2x+5y=15
which goes through the point (-10,1)
now,
let 2x+5y=15 be equation no.1
then the line which is parallel to the equation 1st
2 x+5y+k = 0 let it be equation no.2
now the equation no.2 passes through the point (-10,1)
or, 2x+5y+k =0
or, 2*-10+5*1+k= 0
or, -20+5+k= 0
or, -15+k= 0
or, k= 15
putting the value of k in equation no.2 we get,
or, 2x+5y+k=0
or, 2x+5y+15=0
which is a required line.
Answer:
28 units.
Step-by-step explanation:
The distance between two given points (
) and (
) is given by the formula
So, the distance between points (-2,-4) and (-1,6) is
units.
Now, the distance between points (-1,6) and (3,8) is
units
Again, the distance between the points (-2,-4) and (3,8) is
units.
Therefore,the perimeter of the triangle is (10.05 + 4.47 + 13) = 27.52 ≈ 28 units. (Approximate)
Answer:
No.
Step-by-step explanation:
No, Bob is not correct.
The formula he's using is the following:
The important thing here is that the angle is between the two sides.
In the given triangle, 120 is not between 8 and 18. Therefore, using this formula will not be valid.
Either Bob needs to find the other side first or find the angle between 8 and 18.
