First draw a line and mark 3 points and name them A,P,B given in the question that the point is equidistant from AB. Therefore AP=PB Now take out the mid point of AB That is (x1+x2/2, y1+y2/2) The answer would be (1,4) so the point is this.

ANSWER

What is fundamental theorem of arthmetic ?

According to fundamental theorem of arithmetic every composite number has unique prime factor

0Thank You

Yogita Ingle 6 years, 2 months ago

Every composite number can be expressed (factorised ) as a product of primes, and this factorisation is unique, apart from the order in which the prime factors occur.

This theorem also says that the prime factorisation of a natural number is unique, except for the order of its factors.

For example 20 can be expressed as {tex}2 × 2 × 5 {/tex}

Using this theorem the LCM and HCF of the given pair of positive integers can be calculated.

LCM = Product of the greatest power of each prime factor, involved in the numbers.

HCF = Product of the smallest power of each common prime factor in the numbers.

Sorry...last se 2nd wali ye hogi...√(tan theta +cot theta)²

2Thank You

Aadya Singh ? 6 years, 2 months ago

LHS - √sec²theta + cosec²theta
=> √(1+tan²theta)+(1+cot²theta)
=> √(tan²theta + cot²theta + 2)
=> √(tan²theta + cot²theta + 2×tan theta × 1/tan theta)
=> √(tan²theta + cot²theta + 2×tan theta × cot theta)
=> √(tan²theta + cot²theta)²
=> tan theta + cot theta
Now, LHS = RHS...So, it's prove..

ANSWER

A sector of radius 12cm has the angle of 120degrees it is rolled up so that the two bounding radii are joined together to form a cone find volume of the cone

Posted by Devanshi Parmar 6 years, 2 months ago

CBSE > Class 10 > Mathematics

1 answers

Bhavya Saini 6 years, 2 months ago

Your answer : When the sector is cut from the circle it will have a curved length of one third of the circle. This will be πd/3 where d is the 24 cm diameter of the circle. This yields: π(24)/3 = 8π When the cone is rolled it will then have a circular base with this 8π circumference. The cone will also have a side length of 12 cm, which is important to find the height of the cone. First we need to find the radius of the base of the cone. We know that the circular base has a circumference of 8π and : c=πd So we get: 8π=πd d=8 and r=4 <--- Radius of the circular base. For the height use the Pythagorean theorem: r^2+(height)^2=(side )^2 4^2+(height)^2=12^2 h^2=144-16 h^2=128 h=8√2 Thus the formula for the volume of a cone: V=1/3bh Where b is the area of the base. V=1/3π(4)^2(8√2) V=1/3π128√2 <----- Answer V=189.56 <----- Approximate answer
