The number of stars in 100 billion galaxies in scientific notation is

3 x [tex]10^{22}[/tex].

Scientific Notation is the expression of a number in the form a x [tex]10^{b}[/tex]. where a is an integer such that 1 ≤ |a| < 10 and b is an integer too.

We have,

Number of stars in  our galaxy = 3 x [tex]10^{11}[/tex]

Number of galaxies in the observable universe = 100 billion.

1 billion = 1,000,000,000 = [tex]10^{9}[/tex]

Number of stars in 100 billion galaxies:

= 3 x [tex]10^{11}[/tex] x 100 x  [tex]10^{9}[/tex]

= 3 x [tex]10^{11 + 2 + 9}[/tex]

= 3 x [tex]10^{22}[/tex]

Thus the number of stars in 100 billion galaxies in scientific notation is

3 x [tex]10^{22}[/tex].

The probability that the point of the spinner land on blue is 8.34%.

A pie chart is a type of chart that shows data in a circular graph.

We recognise that the pie's total value is always 100%. It is additionally recognized that a circle has a circumference of 360°. As a result, the sum of all the data equals 360°. Depending on these, there seem to be two main pie chart formulas:

On complete rotation of circle forms 360 degrees at the centre.

The total percentage of the all the colours is 100%.

Divide the value of blue by 3.6 because 360 degrees /100 percent = 3.6.

The total percentage of blue shown by the pointer of spinner is 30%.

Probability P (pointer landing on blue) = 30/3.6

Probability P (pointer landing on blue) = 8.333... = 8.4 (approx.)

Therefore, the probability that the pointer lands on the blue is 8.4.

The equation of the proportional relationship in the table attached below is: y = 40x.

Equation of a proportional relation is modelled as, y = kx. k = y/x, using any pairs of values for a given table. If the table is represents a proportional relationship, y/x for every pair of values would be the same.

Distance in miles = y

Time in hours = x

k = y/x = 80/2 = 120/3 = 160/4 = 40.

The relation represented by the table is proportional because y/x is the same for all pairs of values.

Substitute k = 40 into y = kx

y = 40x.

Thus, the equation of the proportional relationship in the table attached below is: y = 40x.

Step-by-step explanation:

The general form of a linear equation is y - y1 = m(x - x1). The point-slope form is y = - 1.75x.

The general form of a linear equation is y - y1 = m(x - x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).

Given: (x1, y1) = (0, 0) and (x2, y2) = (-4, 7)

The point-slope form is given by,

y - y1 = m(x - x1)

m = (y2 - y1)/(x2 - x1)

substitute the values in the above equation, we get

m = (7- 0)/(-4 - 0) = -7/4

The value of m = -7/4.

y = -1.75x

Therefore, the point-slope form is y = - 1.75x

The the solution of the linear equation in one variable 7(a+1)-3 a=5+4(2a-1) is at a = 3/2.

According to the given question.

We have a linear equation in one variable.

7(a+1)-3 a=5+4(2a-1)

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable 7(a+1)-3 a=5+4(2a-1) is given by

7(a+1) -3a = 5 + 4(2a - 1)

⇒ 7a + 7 - 3a = 5 + 8a - 4    (by distributive rule)

⇒ 4a + 7 = 1 + 8a

⇒ 7 - 1 = 8a - 4a

⇒ 6 = 4a

⇒ 6/4 = a

⇒ a = 3/2

Hence, the the solution of the linear equation in one variable 7(a+1)-3 a=5+4(2a-1) is at a = 3/2.

(e)Limit of h(x) at x=8 is 5

Limit : Limit is the value that a function output approaches as the input  approaches to a certain value.

For any function g(x) , [tex]\lim_{x \to \22} g(x)[/tex] refers to the value that the  g(x) approaches as the x approaches to 2 from either left  hand side or from right hand side

From any graph we can easily see that to what value g(x)=y  on the curve is approaching when the x  is approaching to some value on x axis and if the graph is splitting into different functions on the value of x where x is approaching then the limit does not exist for that value of x.

For given graph h(x)

We can see value of value of function h at x=5 is 8 and value of function h at x=7 is 4

As the graph of h(x) has a hole in the graph when x=5, breaking its function into two different function on x=5 then  or limit of h(x) at x=5 does not exist

As the graph of h(x) has a hole in the graph when x=7, breaking its function into two different function on x=7 then  or limit of h(x) at x=7 does not exist

As the graph is not breaking at x=8or we can say that graph of g(x)is approaching to 5 as x approaches to 8 then limit of h(x) at x=8 is equal to g(1) that is  5
