Answer:

c. Either a minimum or a maximum

Step-by-step explanation:

considering that a parabola can grow or decrease from its vertex we can note that in the case of a parabola with the branches down the vertex will always be a maximum, and in the case of a parabola with the branches up it will always be a minimum.

Points S,U, and T are the midpoints of the sides of PQR. Which statements are correct ? 1/2QP=UT 1/2TS=RQ SU=PR SU||RP UT=RP

Answer:

$\frac{1}{2} QP = UT$

Step-by-step explanation:

GIVEN : In ΔPQR

S is the mid point of QP

U is the mid point of PR

T is the mid point of QR

Solution :

i) is true i.e $\frac{1}{2} QP = UT$

Refer the attached file

By mid segment theorem i.e. In a triangle, the line joining the midpoints of any two sides will be parallel to the third side and that same line joining the midpoints is also half of length of third side .

UT is the line joining the two mid points . So, by theorem given above UT is parallel to PQ and 1/2QP=UT.

So, (i) statement is true i.e. $\frac{1}{2} QP = UT$
