Label A,B,C,D,E in the dicot root. A-metaxylem , B-protoxylem, C-phloem, D-pericycle, E-endodermis.

Differentiate between Protoxylem & Metaxylem.

If a ,b ,c ,d ,e are in A.P., the find the value of a-4b+6c-4d+edot

D , E , F are three points on the sides B C ,C A ,A B , respectively, such that /_A D B=/_B E C=/_C F A=thetadot A^(prime), B ' C ' are the points of intersections of the lines A D ,B E ,C F inside the triangle. Show that are of A^(prime)B^(prime)C^(prime)=4cos^2theta, where is the area of A B Cdot

In A B C , the bisector of the angle A meets the side BC at D andthe circumscribed circle at E. Prove that D E=(a^2secA/2)/(2(b+c))

Let A B C be a triangle with A B=A Cdot If D is the midpoint of B C ,E is the foot of the perpendicular drawn from D to A C ,a n dF is the midpoint of D E , then prove that A F is perpendicular to B Edot

D , E ,a n dF are the middle points of the sides of the triangle A B C , then centroid of the triangle D E F is the same as that of A B C orthocenter of the tirangle D E F is the circumcentre of A B C orthocenter of the triangle D E F is the incenter of A B C centroid of the triangle D E F is not the same as that of A B Cdot

If A={a,b,c,d}, B={e,f,g,d} and C={e,f,c,d} then verify that associative property of intersection of sets.

Identify the given diagram A and label the parts marked as a,b,c,d,e and f.

If U={a,b,c,d,e,f,g,h}, find the complements of the following sets: i. A={a,b,c} ii. B={d,e,f,g} iii. C={a,c,e,g} iv. D={f,g,h,a}

If the diagram, D C is a diameter of the large circle centered at A , and A C is a diameter of the smaller circle centered at B . If D E is tangent to the smaller circle at F and D C=12 then the length of D E is .
