Aston University creates a 10 digit student number as the University enrolls each student. The first two characters must be a digit 1 through 9. The next seven characters can be anything and the last digit just can’t be the same as the ninth character (i.e. the previous digit). How many student numbers are possible?

Answers

Answer 1

Answer:

The number of student numbers that are possible = 729,000,000 student numbers

Step-by-step explanation:

The number of possible numbers that can take the place of the first two digits = 9 possible numbers each

The number of possible numbers that can take the place of the 3rd to the 9th digits = 10 possible numbers each

The number of possible numbers that can take the place of the 10th digits = 9 possible numbers each

The total number of possible numbers is given as follows;

9 × 9 × 10⁶ × 9 = 729000000 possible student numbers

Answers

Answer:

-0.55 + 0.53a

Step-by-step explanation:

              -0.55 – 0.47a + a

 To find an expression equivalent to this, we must simplify the equation to a reasonable extent;

         -0.55 – 0.47a + a

      = -0.55 + 0.53a

      = 0.53a - 0.55

The expression equivalent to the given one is -0.55 + 0.53a  or 0.53a - 0.55

Answer: 1.5x²

Step-by-step explanation:

Rule: To find the area of a triangle, multiply the base times one side, then divide the product by 2.

Step 1: Find the length of the left side using the pythagorean theorem.

a^2 + b^2 = c^2.

x^2 + 2x^2 = 3x^2

√3x² = 3x

Step 2: Multiply the base times the hypotenuse.

x * 3x = 3x²

Step 3: Divide by two

3x²/2 = 1.5x²

Find the equation of the linear function represented by the table below in slope-
intercept form.


y=Mx+B

Answers

Answer:

y = x + 4

Step-by-step explanation:

Let the equation of the linear function represented by the table is,

[tex]y-y_1=m(x-x_1)[/tex]

where m = slope of the line

And this line passes through the points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Slope of the given line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the given table two points lying on the function are (-4, 0) and (1, 5).

Slope 'm' = [tex]\frac{5-0}{1+4}[/tex] = 1

Therefore, equation of the linear function passing through (1, 5) and slope 1 will be,

y - 5 = (x - 1)

y = x + 5 - 1

y = x + 4

Which sequence is generated by the function f(n + 1) = f(n) - 2 for f(1) = 10? ​

Answers

Answer:

The sequence generated will be 10,8,6,4,2,......

Step-by-step explanation:

We want to generate a sequence here

f(n + 1) = f(n) - 2

f(1) = 10

So f(2) = f(1) - 2 = 10 -2 = 8

f(3) = f(2) - 2 = 8-2 = 6

f(4) = f(3) -2 = 6-2 = 4

f(5) = f(4) - 2 = 4-2 = 2

So the sequence will be ;
