The LCD is 42 because that is the least number that they both are factors of.
Hope this helps :)
Answer:
V≈12308.8
Step-by-step explanation:
V=πr2h
V=(3.14)(14)2(20)
R=14cm
H=20cm
π=3.14
Answer:
You can substitute p and q so let's say p=4 and q=3
Step-by-step explanation:
Now 4+3/3+3=6
And you get 4/3
Answer:
(C) -7x − 5y = -48
Step-by-step explanation:
We look for the equation of the line AB
We have then:
y-yo = m (x-x0)
m = (y2-y1) / (x2-x1)
m = (4 - (- 1)) / (4 - (- 3))
m = 5/7
We choose an ordered pair:
(xo, yo) = (4, 4)
Substituting:
y-4 = (5/7) (x-4)
y = (5/7) x-20/7 + 4
7y = 5x - 20 + 28
7y = 5x + 8
y = (5/7) x + 8/7
The equation of the perpendicular line is:
-7x - 5y = -48
Answer:
the equation of BC is:
(C) -7x - 5y = -48
<span>The dot product here is 10(9) + 6(5)=120
so the vectors are not orthogonal
</span><span>u.v = |u| x |v| cos (theta) ; theta is the angle between them
we know from above that u.v = 120
|u| = sqrt[10^2+6^2]=11.66
|v| = sqrt[9^2+5^2]=10.29
so we know:
theta =cos^-1 120/(11.66x10.29)
so theta = 25 degrees</span><span>
