Answer:

a₆ = 21875

Step-by-step explanation:

Using the recursive rule and a₁ = 7 , then

a₂ = 5a₁ = 5 × 7 = 35

a₃ - 5a₂ = 5 × 35 = 175

a₄ = 5a₃ = 5 × 175 = 875

a₅ = 5a₄ = 5 × 875 = 4375

a₆ = 5a₅ = 5 × 4375 = 21875

The total cost of the tiles is £68 plus VAT<br>the rate of VAT is 20%<br>(b) work out 20% of £52​
MArishka [77]

Answer:

a) 81-6

b) 10.4

Step-by-step explanation:

a) assuming that the VAT is 20% of the 68 pounds,

you calculate 120% of 68 (convert percentage to decimal)

= 1,20 * 68 = 81.6 pounds

or

calculate 20% of 68 pounds and add the answer to 68 pounds:

(0.2 * 68) + 68 = 81.6 pounds

b) 20% of 52

first convert the percentage to decimals:

0.2 * 52 = 10.4 pounds

Y = –3x2 – 12<br><br> Axis of symmetry:
kicyunya [14]
<h3>Answer:   x = 0</h3>

Work Shown:

y = -3x^2 - 12 is the same as y = -3x^2 + 0x + (-12)

Compare this to y = ax^2 + bx + c, and we'll find that

a = -3

b = 0

c = -12

Plug the 'a' and 'b' values into the formula below and simplify

h = -b/(2a)

h = -0/(2*(-3))

h = 0

The x coordinate of the vertex is x = 0, so the axis of symmetry is also x = 0.

The axis of symmetry lays perfectly on top of the y axis.
