State a function rule for the number of dots in each figure

Mathematics

Answer:

g(x)=x^{2}

Step-by-step explanation:

Since we know that a function gives exactly one output for a given input.

We can see that number of points in our diagram are 1,4 and 9.

These numbers represent a quadratic function as:

1^{2} =1

2^{2} =4

3^{2} =9

Therefore, we can represent these points in a function as g(x)=x^{2}, where x is number of points.

Answer:

Solution → (3, -1)

Step-by-step explanation:

We ave to identify the graph representing the system of lines first.

y = \frac{2}{3}x-3

Y-intercept of the line = -3

y = -2x + 5

y-intercept of the line = 5

From the given graphs 3rd (extreme right) graph is representing the system of equations.

Solution of the system of equations will be the point of intersection of these lines.

Solution of the system → (3, -1)

What is the benchmark fraction of 7/10 x 16
Tomtit [17]
Lets change "16" by its to 16/1 .. since nothing can't help support 16 by itself when it is going into 7/10

Now that we change that ... your problem becomes 7/10 × 16/1

7/10 × 16/1 = 11 1/5

Because
7(16) / 10(1) = 112/10
Now lets go. to how we solve the for the answer

112/10 = 11 1/5

It represents a geometric sequence because it has a common ratio of 2.

In fact, a sequence is said to be geometric if any two adjacent elements are in the same ratio. In other words, if you choose any index n \in \mathbb{N} and consider the two consecutive terms a_n and a_{n+1}, you have

\dfrac{a_{n+1}}{a_n} = r

no matter which index you chose. In your case, the next term in the sequence is always the double of the previous one, so the ratio between two consecutive terms is always 2, and the series is geometric with common ratio 2

aev [14]

Answer:

Statement 4 is correct

Step-by-step explanation:

Here, we want to select which statement is true based on the given diagram;

The statement that must be true is that Y is the midpoint of XV

This is because, by bisection , we mean dividing into 2 equal parts

The line UW has divided the line XV into two equal parts

So this mean that Y is the midpoint of the line XV
