If t varies as v, and t = 2 4/7 when v =13/14 , find v when t = 2 1/4

maks197457 [2]

Answer : b) 13/16

Given : t varies as v

So t = k v where k is the constant of proportionality.

t = 2 4/7 when v =13/14. Using these values we find out k

$t = 2\frac{4}{7} =\frac{18}{7}$

$v =\frac{13}{14}$

t = k * v

$\frac{18}{7}= k *\frac{13}{14}$

Multiply by 14/13 on both sides

$\frac{18}{7} *\frac{14}{13} = k *\frac{13}{14}*\frac{14}{13}$

So $k =\frac{36}{13}$

We got the value of k. Now we find v when t = 2 1/4

$t = 2\frac{1}{4} =\frac{9}{4}$

t = k * v

We know the value of t and k

$\frac{9}{4}= \frac{36}{13}* v$

Multiply by 13/36 on both sides

$\frac{9}{4} *\frac{13}{36} =\frac{36}{13}*\frac{13}{36}* v$

So $\frac{13}{16}= v$

Option B is correct

We can infer and logically deduce that the arc intersected by these chords are not congruent.

<h3>What is a circle?</h3>

A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).

In Geometry, a circle is generally considered to be a conic section which is formed by a plane intersecting a double-napped cone that is perpendicular to a fixed point (central axis) because it forms an angle of 90° with the central axis.

In Geometry, an arc can be defined as a trajectory that is generally formed when the distance from a given point has a fixed numerical value.

Let the radii of the two (2) different circles with center O and O' be r₁ and r₂ respectively. Also, two (2) isosceles triangles AOB and COD would be formed and as such we have:

AO = OB = r₁.

CO = O'D = r₂.

By critically observing the diagram (see attachment) of these circles, we can logically deduce that the arc intersected by chord AB is greater than the arc intersected by the chord CD.

This ultimately implies that, the arcs intersected by these chords are not congruent.

<u>Complete Question:</u>

Two circles with different radii have chords AB and CD, such that AB is congruent to CD. Are the arcs intersected by these chords also congruent? Explain.

Hint: It would be helpful to draw two circles and label them according to the given information, then evaluate possible arc measures.

Consider the type of triangle that may be drawn by connecting the endpoints of a chord to the center of a circle. Compare the triangles made by two circles with different radii.
