Apply Pythagoras:

length = sqrt( (10--4)² + (6-3)² ) = sqrt(205)

Answer:  The correct option is (B) \sqrt{205}.

Step-by-step explanation:  We are given to find the length of the segment whose endpoints are A(-4, 3) and B (10, 6).

We know that

the length of a line segment with endpoints (a, b) and (c, d) is calculated using distance formula as follows :

D=\sqrt{(c-a)^2+(d-b)^2}.

Therefore, using distance formula, the distance between the endpoints A(-4, 3) and B (10, 6) is given by

AB\\\\=\sqrt{(10-(-4))^2+(6-3)^2}\\\\=\sqrt{(10+4)^2+3^2}\\\\=\sqrt{14^2+9}\\\\=\sqrt{196+9}\\\\=\sqrt{205}.

Thus, the length of the line segment AB is \sqrt{205}~\textup{units}.

Option (B) is CORRECT.

Estimate the sum 8/10 + 1/9
RideAnS [48]

Answer:

41/45

Step by Step Explanation:

Add: 8/

10

+ 1/

9

= 8 · 9/

10 · 9

+ 1 · 10/

9 · 10

= 72/

90

+ 10/

90

= 72 + 10/

90

= 82/

90

= 2 · 41/

2 · 45

= 41/

45

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 9) = 90. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 9 = 90. In the following intermediate step, cancel by a common factor of 2 gives 41/

45

.

In other words - eight tenths plus one ninth = forty-one forty-fifths.

A dragonfly can beat its wings 30 times a second. write an equation in slioe intercept form that shows the relationship between
ivanzaharov [21]

Answer:

1800

Step-by-step explanation:

Since there is the tragon fly beat his wings 30 times a second ,there is 60 hundredths of a second in a second multiply 30 x 60 and you should get 1800.

  1. mulitiply 0x0 = 0

     2.  mulitiply 6x0=0

        3. multiply 3x0=0

          4. mulitiply 6x3 = 18

            5. have 1800

or you can just multiply 6x3 = 18 and add the two zeros
