Answer: 32

Determine which statements are true in reals3. (Selectall that apply.)

Serggg [28]

Answer:

(a)Two lines parallel to a third line are parallel.

(c) Two planes parallel to a third plane are parallel.

(f) Two lines perpendicular to a plane are parallel.

(h) Two planes perpendicular to a line are parallel.

(i) Two planes either intersect or are parallel.

(k) A plane and a line either intersect or are parallel

Step-by-step explanation:

(b) Two lines perpendicular to a third line are parallel. -- No. The y-, and z-axes are perpendicular to the x-axis, but are not parallel.

(d) Two planes perpendicular to a third plane are parallel. -- No. The x-y and y-z coordinate planes are both perpendicular to the x-z coordinate plane, but are at right angles to each other.

(e) Two lines parallel to a plane are parallel. -- No. Two intersecting lines in the plane z=0 are both parallel to the plane z=1, but are not parallel to each other.

(g) Two planes parallel to a line are parallel. -- No. Both the x-z plane and the y-z plane are parallel to the line (x, y, z) = (1, 1, z), but those coordinate planes are perpendicular to each other.

(j) Two lines either intersect or are parallel. -- No. The lines may be skew, running different directions in parallel panes.

Correct function combinations to x2-7x-18

Natasha_Volkova [10]

The factors of the function after factorization f(x)= $x^{2} -7x-18$ is (x+2) and (x-9)

Given Function f(x)= $x^{2} -7x-18$ and we have to find the factors of the given function.

The function whose factors are to be found is f(x)= $x^{2} -7x-18$

Factorization means finding various expressions which when together multiplied will give the function itself. Correct combination can only be found by finding the factors of the function. Without finding factors no one can find the solution of an equation or expression also.

f(x)= $x^{2} -9x+2x-18$

=x(x-9)+2(x-9)

=(x+2)(x-9)

Hence the factors which when combine together gives function f(x)= $x^{2} -7x-18$ are (x+2)(x-9).
