Find the midpoint of the segment with these endpoint (4,6),(9,3)​
Usimov [2.4K]

Answer:

The midpoint of the segment is (6, 4.5).

Step-by-step explanation:

Midpoint of a segment:

The midpoint of a segment is given by the mean of the coordinates of their endpoints.

Segment with coordinates (3,6) and (9,3).

Mean x-coordinate: (3+9)/2 = 12/2 = 6

Mean y-coordinate: (6+3)/2 = 9/2 = 4.5

The midpoint of the segment is (6, 4.5).

ELEN [110]
We can eliminate one of the variables to solve for the other variable, as in both equations, y has opposite coefficients. Combine these two equations:

2x = 246

Divide both sides by 2 to get x by itself:

x = 123

Plug this value into the second equation:

123 + y = 212

Subtract 123 from both sides to get y by itself:

y = 89

Find an equation of the plane that passes through the points p, q, and r. ​ p(7, 2, 1), q(6, 3, 0), r(0, 0, 0)
Alona [7]

Answer:

x - 2y - 3z = 0

Step-by-step explanation:

The cross product of vectors rp and rq will give a vector that is normal to the plane:

... rp × rq = (-3, 6, 9)

Dividing this by -3 (to reduce it and make the x-coefficient positive) gives a normal vector to the plane of (1, -2, -3). Usint point r as a point on the plane, we find the constant in the formula to be zero. Hence, your equation can be written ...

... x -2y -3z = 0

A. 44.99 + 0.75(29.99)x = 44.99 + 22.49x

B. 1.08(44.99 + 22.49x ) 

C. 1.08(44.99 + 22.49(4)) = 1.08 (44.99 + 89.96) = 1.08(134.95) = 145.75

The lateral area of a cone is 555 \pi cm^2 and the radius is 15.1 what is the slant height?
pishuonlain [190]
We know that
[LA]=pi*r*l
where
LA is the lateral area of the cone
r is the radius
l is the slant height
l=LA/(pi*r)
r=15.1 cm
LA=555*pi cm²
l=(555*pi)/(pi*15.1)----> l=36.75 cm

the answer is
the slant height is 36.75 cm
