3.	Find the length of the median from the vertex B of ∆ABC whose vertices root 13 are A(1, -1), B(0, 4) and C(-5, 3)
Answer» Find the length of the median from the vertex B of ∆ABC whose VERTICES are A(1, -1), B(0, 4) and C(-5, 3) (correct question) Given: ∆ABC whose vertices are A(1, -1), B(0, 4) and C(-5, 3) To find: The length of the median from vertex B Solution: 1) The median from vertex B will be the mid-point of AC. 2) COORDINATE of the foot of the median is given by: Mid-point of AC x = 1+(-5)/2 =-4/2 = -2 y = -1+3/2 = 2/2 = 1 Now, the vertex of the median is (0,4) and (-2,1) 3) We will find the length of the median by the distance formula, $\sqrt{(x2-x1)^{2}+(<klux>Y2</klux>-y1)^{2} }$ (x1,y1) = (0,4) (x2, y2) = (-2,1) $\sqrt{(-2-0)^{2}+(1-4)^{2} }$ $\sqrt{(-2)^{2}+(-3)^{2} }$ $\sqrt{4+9 }$ $\sqrt{13}$ The length of the median is √13

Find the length of the median from the vertex B of ∆ABC whose vertices root 13 are A(1, -1), B(0, 4) and C(-5, 3)

Answer»

Find the length of the median from the vertex B of ∆ABC whose VERTICES are A(1, -1), B(0, 4) and C(-5, 3) (correct question)

Given:

∆ABC whose vertices are A(1, -1), B(0, 4) and C(-5, 3)

To find:

The length of the median from vertex B

Solution:

1) The median from vertex B will be the mid-point of AC.

2) COORDINATE of the foot of the median is given by:

Mid-point of AC

x = 1+(-5)/2 =-4/2 = -2

y = -1+3/2 = 2/2 = 1

Now, the vertex of the median is (0,4) and (-2,1)

3) We will find the length of the median by the distance formula,

$\sqrt{(x2-x1)^{2}+(<klux>Y2</klux>-y1)^{2} }$

(x1,y1) = (0,4)

(x2, y2) = (-2,1)

$\sqrt{(-2-0)^{2}+(1-4)^{2} }$

$\sqrt{(-2)^{2}+(-3)^{2} }$

$\sqrt{4+9 }$

$\sqrt{13}$

The length of the median is √13

Step-by-step explanation:

by using the shortcut method :

step 1 :

first for the numerator SUBTRACT the digits before the decimal point in the given decimal from all the digits the given decimal ( without considering point )

422345-42

= 422303. - numerator

step 2 :

for the denominator WRITE 9 as many times as many digits under bar , if there is a number that is not under the bar behind the decimal add a zero as many times as the digit ( for example 5.6789 and the bar is under 89 then the denominator will be 9900 ) ( in this question there is no need for that )

9999 - denominator

so the number in fraction form is

Answer» Step-by-step explanation: we have to add a NUMBER to -16/3 to make it 1/9. therefore, we first convert it into an EQUATION which is -16/3 + any number = 1/9. let us ASSUME the number to be X. therefore, we get -16/3 + X = 1/9 when we solve this equation, we get 147/27 which is the answer. therefore, 147/27 should be ADDED to -16/3 to make it 1/9.

40.

What should be added to -16/3 to mark it 1/9?

Answer»

Step-by-step explanation:

we have to add a NUMBER to -16/3 to make it 1/9.

therefore, we first convert it into an EQUATION which is -16/3 + any number = 1/9.

let us ASSUME the number to be X.

therefore, we get

-16/3 + X = 1/9

when we solve this equation, we get 147/27 which is the answer.

therefore, 147/27 should be ADDED to -16/3 to make it 1/9.

44.	Find the circumference of a circle with diameter, d = 4.7m. Give your answer rounded to 2 DP.
Answer» Step-by-step explanation: we can answer this by using the FORMULA for circumference of a circle, i.e, 2πr or πd where r = radius and d = diameter. therefore, circumference will be πd because d is given as 4.7 m. we can use EITHER VALUES for π, 22/7 or 3.14, because it's not mentioned in the question which one we have to use. we get 14.77....m by using 22/7 and 14.758m by using 3.14. now, considering 14.758m, because it is a RATIONAL number, we get 14.76m when we ROUND it off to two decimal places. therefore the required answer is 14.76m.

Find the circumference of a circle with diameter, d = 4.7m. Give your answer rounded to 2 DP.

Answer»

Step-by-step explanation:

we can answer this by using the FORMULA for circumference of a circle, i.e, 2πr or πd

where r = radius and d = diameter.

therefore, circumference will be

πd because d is given as 4.7 m.

we can use EITHER VALUES for π, 22/7 or 3.14, because it's not mentioned in the question which one we have to use.

we get 14.77....m by using 22/7 and 14.758m by using 3.14.

now, considering 14.758m, because it is a RATIONAL number, we get 14.76m when we ROUND it off to two decimal places.

therefore the required answer is 14.76m.
