Answer:

41. s = semiperimeter

s = (a + b + c) /2

s = (120+170+250) /2

s = 270m

d is the correct option.

42. b is the correct option.

43. P = a + b + c

P = 120+170+250

P = 540m

a is the correct option.

44. A = √s((s-a)(s-b)(s-c))

=√270((270-120)(270-170)(270-250))

=9000m²

d is the correct option.

45. length of wire=P - space for gate

= 540 - 3

=537m

b is the correct option.

Answer:

option A. y = 1/2 x

Step-by-step explanation:

given the equation:

y - 9 = 1/2 ( x - 3 )

here the gradient is 1/2

if passes parallel the gradient is same.

the line pass through ( -2 , -1 )

so,

y - y1 = m( x -  x1 )

y - - 1 = 1/2 ( x - -2 )

y + 1 = x/2 + 1

y = 1/2 x

Therefore option A is correct.

Answer:

  3. vertical stretch by a factor of 2; shift right 1 and down 1

  4. shift left 4 and up 4 (no stretch or shrink)

Step-by-step explanation:

The vertex form equation is ...

  y = a(x -h)^2 +k

It represents a vertical stretch of the parent function by a factor of 'a', a right shift of 'h', and an upward shift of 'k'.

Compare the the given equations to the above form to see the transformations.

__

3. (a, h, k) = (2, 1, -1)   ⇒   vertical stretch by a factor of 2; shift right 1, down 1

4. (a, h, k) = (1, -4, 4)   ⇒   no vertical stretch; shift left 4, up 4
