  • Answer:
  • < abc =  < ebc \\  < acb =  < ecd \\ if \: two \: angles \: in  \:  the \:two \: different \:  triangles \: are \: equal \: then \: the \: third \: angle  \: in \: the \: triangle\: must \: be  \:  equal. \\ using \: pythogres \: theorum   \\  ab = \sqrt( ac ^{2}  - bc^{2} )\\  =  \sqrt (15 ^{2}  - 12 ^{2})  \\  =  \sqrt( 225 - 144 )\\  =   \sqrt(81) \\  ab = 9 \\ sides \: of \: similar \: triangle \: are \: propotional \\   ac  \div ec = dc \div bc \\ 15 \div x = 12 \div 6\\ x = 15 \times 6\div 12\\ x = 15  \div  2 \\ x = 7.5 \\ so \: ec \:  = 7.5 \\ you \: can \: check \: this \: by \: applying \: pythogores \: theorum. \\ i \: hope \: this  \:  helps

You are given an original figure with coordinates B(-7,-2), A(5,-2), and D(-7,7) and its image with coordinates J(-3,0), K(1,0),
MAVERICK [17]

Answer:

see below

Step-by-step explanation:

DB = 9  units  (by counting)

BA = 12 units  (by counting)

DA  can be found by using the pythagorean theorem

a^2 +b^2 = c^2

BD^2 + BA^2 = DA ^2

9^2 +12^2 = DA^2

81 +144 = DA^2

225 = DA ^2

Take the square root of each side

sqrt(225) = sqrt(DA^2)

15 = DA

LJ = 3  units  (by counting)

JK = 4 units  (by counting)

LK  can be found by using the pythagorean theorem

a^2 +b^2 = c^2

LJ^2 + JK^2 = LK ^2

3^2 +4^2 = LK^2

9 +116 = LK^2

25 = LK ^2

Take the square root of each side

sqrt(25) = sqrt(LK^2)

5 = LK

Scale factor from BAD to JKL

15 to 5

Divide each side by 5

3 to 1

We multiply by 1/3 to go from the big to small

The weight, w, of a spring in pounds is given by 0.9 times the square root of the energy, E, stored by the spring in joules. If
stira [4]
The is the concept of algebra, the weight of the spring can be modeled by the equation;
w=0.9sqrt E
where;
=energy in joules;
thus the weight of the spring when the energy is 12 j will be:
w=0.9sqrt12
w=3.18 g

3 - 4 x 2 The first step to evaluate the expression is ...
sveticcg [70]

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)

3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5

5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11

15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2

5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.
