(D)We can prove THEOREMS with geometric rules........
Archy [21]3 years ago

Answer with explanation:

A.→Experiment

In Experiments we do not require basic geometrical equipment.While doing experiment, to find the value of g, we use string, cork to find value of g(Acceleration due to gravity).We use different locations, to check whether value of g is same or it differs.There is no geometric proof required.

B.→Opinions

  In opinion we use our senses to answer.Someone has better sense, he or she can provide better opinion on that issue ,where opinion is being taken.So,there is no geometrical use or geometric proof required while taking or forming opinion.

C:→Postulates

 are the mathematical truths which do not require any proof.They are universally true statement which is used for proving other mathematical statement.

D: →Theorems

While dealing with areas and volumes of fields and different solid, we use theorems so, that things can be calculated or evaluated in more appropriate way.So, to prove theorems we require things which we call geometrical equipment.While dealing with theorems we use geometrical proof in which geometrical equipment like compass, ruler,set Square is required.

4. k/6 = 8/16 5. 5.4/7 = 27/h 6. 8/11 = 4/y+2
kupik [55]

Answer:

4. k=3\\

5. h=35

6. \frac{7}{2} or 3.5

Step-by-step explanation:

\frac{k}{6}=\frac{8}{16}

Multiply those 2 values whose diagonal has both terms and divide by the term whose diagonal has the variable.

k=\frac{8*6}{16}\\ k=\frac{48}{16}\\ k=3

-----------------------------------------------------------------------

\frac{5.4}{7}=\frac{27}{h}

h=\frac{7*27}{5.4} \\h=\frac{189}{5.4}\\ h=35

-------------------------------------------------------------------------

\frac{8}{11}=\frac{4}{y+2}

y+2=\frac{11*4}{8}\\ y=\frac{11*4}{8}-2\\y=\frac{44}{8}-2 \\y=\frac{11}{2}-2\\ y=\frac{11-2*2}{2}\\ y=\frac{11-4}{2}\\ y=\frac{7}{2}=3.5

Can you write the equation for a circle if the given point does not lie on the circle? Explain .
Pachacha [2.7K]

Answer:

No

Step-by-step explanation:

The equation of a circle with center (a,b) and radius r is given as:

{(x - a)}^{2}  +  {(y - b)}^{2}  =  {r}^{2}

If a given point (x,y) does not lie on this circle, it will not satisfy its equation.

This means the distance from the point to the center is not equal to the radius.

It is either less or greater than the radius.

Hence you cannot write the equation of the circle.
