Answer:

B. The square root of 16 is 4., and 4 is a whole number. A whole number is a part of the rational family.

Step-by-step explanation:

Remember: A rational number is any number that can be written into a fraction. Such as integers.

A is incorrect because 15 is not a whole numer, and it's decimals are not repeating with a pattern or terminating.

B is correct because the square root of 16, which is 4, is a whole number.

C is incorrect because 21 is not a whole numer, and it's decimals are not repeating with a pattern or terminating.

D is incorrect because 22 is not a whole numer, and it's decimals are not repeating with a pattern or terminating.

Hilary's house has a value of £180 000 correct to 2 significant figures.
Gemiola [76]

The least and highest value of the house before being rounded are £184999 and £175000 respectively.

The initial value of Sue's house before the increase is £205,000

£180,000 correct to 2 significant figures :

The greatest value of the house would be a sum in which the third significant figure is a value less than 5 and the succeeding values are highest

  • £184999

The least value of house would be a sum in which the third significant value is 5 and the succeeding values are lowest.

  • £175000

2.)

Let the price before the increase = p

  • Price after increase = £219350

7% of p = 219350

(1+7%) × p = 219350

1.07p = 219350

p = 219350 / 1.07

p = £205,000

Therefore, the price of the house before the increase is p = £205,000

Write a function in any form that would match the graph shown below
ella [17]

Answers:

  • Vertex form:  y = -2(x-1)^2 + 8
  • Standard form: y = -2x^2 + 4x + 6

Pick whichever form you prefer.

=============================================================

Explanation:

The vertex is the highest point in this case, which is located at (1,8).

In general, the vertex is (h,k). So we have h = 1 and k = 8.

One root of this parabola is (-1,0). So we'll plug x = -1 and y = 0 in as well. As an alternative, you can go for (x,y) = (3,0) instead.

Plug those four values mentioned into the equation below. Solve for 'a'.

y = a(x-h)^2 + k

0 = a(-1-1)^2+8

0 = a(-2)^2+8

0 = 4a+8

4a+8 = 0

4a = -8

a = -8/4

a = -2

The vertex form of this parabola is   y = -2(x-1)^2+8

Expanding that out gets us the following

y = -2(x-1)^2+8

y = -2(x^2-2x+1)+8

y = -2x^2+4x-2+8

y = -2x^2+4x+6 .... equation in standard form
