IfA=(-2,-4) and B=(-8,4), what is the length of AB?

lisabon 2012 [21]

Answer:

<h2>10 units </h2>

solution,

A(-2,-4)--->(X1,y1)

B(-8,4)----->(x2,y2)

now,

$ab = \sqrt{(x2 - x1) ^{2} + {(y2 - y1)}^{2} } \\ \: \: \: \: = \sqrt{ (- 8 - ( - 2)) ^{2} + (4 - ( - 4)) ^{2} } \\ \: \: \: = \sqrt{( - 8 + 2) ^{2} + {(4 + 4)}^{2} } \\ \: \: \: = \sqrt{( - 6) ^{2} + {(8)}^{2} } \\ \: \: = \sqrt{36 + 64} \\ \: \: \: = \sqrt{100} \\ \: \: \: = \sqrt{ {(10)}^{2} } \\ \: \: \: \: = 10 \: units$

Hope this helps..

A library ordered 956 new books. They ordered 12 times as many mystery books as romance. They ordered 52 more science fiction bo

Nataly_w [17]

Answer:

Romance books ordered = 65

Mystery books ordered = 775

Science Fiction book Ordered ≈ 116

Step-by-step explanation:

Total number of books ordered in the library = 956

Let us assume the number of romance books ordered = m

⇒Number of mystery books ordered = 12 x (Number of romance books)

= 12 x(m) = 12 m

Also,number of science books ordered = 52 +(Number of romance books)

= 52 + m

Now, according to the question:

Number of { romance books + mystery books + science books} = 956

or, m + ( 12 m ) + (52 + m) = 956

or, 14 m = 956 - 52

or, 14 m = 904

⇒ m = 904/ 14 = 64.6

So, the number of romance books ordered = 64.6 ≈ 65

Number of mystery books ordered = 12 m = 12 x 64.5 = 775

Number of science fiction book ordered = = 52 + m = 116.6 ≈ 116
