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

The diagram below shows a three dimensional view of the pool.
shutvik [7]

Answer:

a) A_{f} = 408.54\,m^{2}, b) A_{w} = 106.2\,m^{2}

Step-by-step explanation:

a) The floor area of the pool is:

A_{f} = (10\,m)\cdot (12\,m)+(18\,m)\cdot (16.03\,m)

A_{f} = 408.54\,m^{2}

b) The total area of the walls of the pool is:

A_{w} = 2\cdot (0.9\,m)\cdot (16\,m) + (0.9\,m)\cdot (16\,m) + (18\,m)\cdot (1.8\,m)+ 2\cdot (12\,cm)\cdot (0.9\,m)+(10\,m)\cdot (0.9\,m)

A_{w} = 106.2\,m^{2}

trasher [3.6K]

Answer:

2x - 2y = -8

x + 2y = -1

3x = -9

x = -3

-3 + 2y = -1

2y = 2

y = 1

(-3, 1) is the solution

Write the word sentence as an inequality.<br> One plus a number y is no more than -13.
kolbaska11 [484]

Answer:

1+y \leq -13

Step-by-step explanation:

The problem states that one plus y is No greater than -13.

This means that is less than or equal to -13.

It also gives you one plus y, or 1+y

Put everything together to get 1+y \leq -13
