Y varies jointly as a and b and inversely as the square root of c. y equals 16y=16 when a equals 4 comma=4, b equals 5 commab=5, and c equals 25.c=25. Find y when a equals 5 comma=5, b equals 4 commab=4, and c equals 4.c=4. Find y when a equals 5 commaa=5, b equals 4 commab=4, and c equals 4.c=4.

y=40

Step-by-step explanation:

If y varies jointly as a and b

y∝ab

If y varies inversely as the square root of c

y∝

Combining the two

y∝

Introducing Variation Constant

y=16, When a=4, b=5, c=25

Therefore the equation connecting a. b and c is:

We are to determine y when a=5, b=4 and c=4

a

step-by-step explanation:

a

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
