Answer:

4.68\times10^9

Step-by-step explanation:

Scientific notation is defined as a way of writing very large or very small numbers.

A number between 1 to 10 is written in scientific notation when it is multiplied by a power of 10.

Here the given scenario is :

A star has a diameter of 4,680,000,000 units.

So, in scientific notation we can write this as :

4.68\times10^9

We can check this if we multiply this by 10^9. This will shift the decimal to 9 places in the right side.

The function f(t)=t^2+12t-18 represents a parabola. Part A: Rewrite the function in vertex form by completing the square. Show y
ale4655 [162]
The function in vertex form is f(t) = (t+6)^{2} -54 (refer to your other post I solved it there).
The general form of quadratic equations in vertex form is f(x) = a(x-h)^{2} +k, where (h, k) is the vertex of the parabola.
Here, a = 1, h = -6 and k = -54
Therefore, the vertex is (-6, -54) and it is a maximum because a = 1 is postive.

Quadrilateral CAMP below is a rhombus. The length of PQ is (x + 2) units, and the length of QA is
Phoenix [80]

Q cuts the diagonal PA into 2 equal halves, since the diagonals of rhombus meet at right angles.

<u>Step-by-step explanation:</u>

As given by the statement in the problem,

Q may be the middle point, which cut the diagonal PA into 2 equal halves.

In rhombus, diagonals meet at right angles.

which means that PQ = QA

x+2 = 3x - 14

Grouping the terms, we will get,

3x -x = 14+ 2

2x = 16

dividing by 2 on both sides, we will get,

x = 16/2 = 8

8+2 = 3(8) - 14 = 10 = PQ or QA
