Answer» ANSWER :— <P> Given that, Points P(p,-2) and Q(5/3,q) trisect the line AB.

Integrate it plzzz...

Answer»

ANSWER :—

<P>

Given that,

Points P(p,-2) and Q(5/3,q) trisect the line AB.

The given points are A(3,-4) and B(1,2)

Now,

P(p,-2) divides the line in the ratio 1:2.

$\setlength{\unitlength}{1cm}\thicklines\begin{picture}(10,6)\put(0,0){\line(1,0){9}}\put(0,0){\circle*{0.1}}\put(0,-0.5){\sf A\;(3,-4)}\put(3,0){\circle*{0.1}}\put(3,-0.5){\sf P\;(7/3,-2)}\put(6,0){\circle*{0.1}}\put(6,-0.5){\sf Q\;(5/3,0)}\put(9,0){\circle*{0.1}}\put(9,-0.5){\sf B\;(1,2)}\end{picture}$

By using Sector's formula,

$\star \ \boxed{\boxed{\sf Z(x,y) = \bigg(\dfrac{nx_2 + mx_1}{m + n},\dfrac{ny_2 + my_1}{m + n} \bigg)}}$

Thus,

$\sf P(p,-2) = \bigg(\dfrac{1(1) + 3(2)}{1+2},\dfrac{2(1) -4(2)}{1+2} \bigg)$

Therefore,

$\implies \sf p = \dfrac{1 + 6}{3} \\ \\ \implies \boxed{ \boxed{\sf p = \dfrac{7}{3} }}$

Also,

Q is the MIDPOINT of line PB.

By using Midpoint formula,

$\star \ \boxed{\boxed{\sf Z(x,y) = \bigg( \dfrac{x_1 + x_2}{2},\dfrac{y_1 + y_2}{2} \bigg)}}$

Thus,

$\sf Q(\dfrac{5}{3},q) = \bigg(\dfrac{\frac{7}{3} + 1}{2},\dfrac{-2 + 2}{1+2} \bigg)$

Therefore,

$\implies \sf \: q = \dfrac{2 - 2}{2} \\ \\ \implies \boxed{ \boxed{ \sf q = 0}}$

• The values of p and q are 7/3 and 0 respectively

Using a ruler measure the diameter of each circular object. Record the measures in a table as shown below.Object Diameter (in cm) Circumference (in cm) Step 2. Make a small mark or a point at the edge of the circular object. Keep a measuring tape on a flat surface. Place the mark at the beginning of the tape. Roll the object along the tape for one rotation, until you reach the mark again.Step 3. Record the length in the table. This is the circumference.Step 4. Find the ratio of circumference of the circular object to its diameter. i.e. Step 5. Repeat the activity for the remaining two objects and write your observation.
Answer» Answer: CIRCUMFERENCE of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as CM or unit m. When we use the formula to calculate the circumference of the circle, then the radius of the circle is taken into account. Hence, we NEED to know the VALUE of the radius or the diameter to EVALUATE the perimeter of the circle. Circumference of a Circle Formula The Circumference (or) perimeter of a circle = 2πR where, R is the radius of the circle π is the mathematical constant with an approximate (up to two decimal points) value of 3.14 Again, Pi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle. where C = π D C is the circumference of the circle D is the diameter of the circle For example: If the radius of the circle is 4cm then find its circumference. Given: Radius = 4cm Circumference = 2πr = 2 x 3.14 x 4 = 25.12 cm

Answer:

CIRCUMFERENCE of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as CM or unit m.

When we use the formula to calculate the circumference of the circle, then the radius of the circle is taken into account. Hence, we NEED to know the VALUE of the radius or the diameter to EVALUATE the perimeter of the circle.

Circumference of a Circle Formula

The Circumference (or) perimeter of a circle = 2πR

where,

R is the radius of the circle

π is the mathematical constant with an approximate (up to two decimal points) value of 3.14

Again,

Pi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle.

where C = π D

C is the circumference of the circle

D is the diameter of the circle

For example: If the radius of the circle is 4cm then find its circumference.

Given: Radius = 4cm

Circumference = 2πr

= 2 x 3.14 x 4

= 25.12 cm

Principal = Rs . 15000
Rate Of Interest = 8% Per Annum.

Amount = Rs.15000×2 = Rs.30000

Therefore, Interest= 30000-15000= Rs.15000 (Amount - Principal)

Let Time PERIOD Be T

SI= P×R×T/100

SI=15000×8%×T/100

Interest=

(15000/100)=(15000×8×t/100)

((do the cuttings then))

=12.5 YEARS Answer

Will Come.

Time Period For principal To DOUBLE Is 12Years And 6 Months.

We know that, The area of a right angled triangle = ⇒ ⇒ x(3x+3) = 84 × 2 = 168 ⇒ Dividing by 3, we get ⇒ ⇒ ⇒ x(x + 8) - 7(x + 8) = 0 ⇒ (x + 8)(x - 7) = 0 ⇒ x + 8 = 0 or, x - 7 = 0 ⇒ x = - 8 or, x = 7 [ ∵ -7 is not possibe because side never be negative] ⇒ x = 7 ∴ 3x + 3 = 3 × 7 + 3 = 24 In a right angled triangle , Hypoyaneous, h = Thus, the hypotenuse of the right angled triangle(h) = 25 cm

Which of the following are sides of a right angled triangle? 3cm

Answer»

Answer:

Step-by-step EXPLANATION:

The hypotenuse of the right angled triangle(H) = 25 cm

Step-by-step explanation:

Let the one side of a right angled triangle(b) = x and

The other side of a right angled triangle (h) = (3x + 3)

Given, the area of the triangle = 84

To find, the hypotenuse of the triangle (h) = ?

We know that,

The area of a right angled triangle =

⇒

⇒ x(3x+3) = 84 × 2 = 168

⇒

Dividing by 3, we get

⇒

⇒ x(x + 8) - 7(x + 8) = 0

⇒ (x + 8)(x - 7) = 0

⇒ x + 8 = 0 or, x - 7 = 0

⇒ x = - 8 or, x = 7 [ ∵ -7 is not possibe because side never be negative]

⇒ x = 7

∴ 3x + 3 = 3 × 7 + 3 = 24

In a right angled triangle ,

Hypoyaneous, h =

Thus, the hypotenuse of the right angled triangle(h) = 25 cm
