The limits of the range for the length of time that Act 3 could last is 33.6

The values that a function approaches for the specified input values are known as limits in mathematics. Limits are essential to calculus and mathematical analysis because they help define concepts like integrals, derivatives, and continuity. It's employed in the analysis process and always has to do with how the function behaves at a specific moment. In the idea of the limit of a topological net, the limit of a sequence is further generalized and connected to the limit and direct limit in the theory category. In general, integrals are divided into two categories: definite integrals and indefinite integrals.

A 24-hour period was predicted for Act 3 of the 2003 Leonid meteor shower. This prediction had a 0.7-day error window. How long could Act 3 potentially last, in the range

Lower Limit: 24-0.7(24) = 0.3(24) = 7.2 hrs

Upper Limit: 24+0.7(24) = 40.8 hrs

Range = Upper Limit - Lower Limit

= 40.8 - 7.2

=33.6

The measure of the angle 15 is 97°

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles.

The parallel lines are e and f. These parallel lines are cut across by the transversal lines c and d. The transversal line d is the line that forms the angle 15 with the parallel lines e and f.

Therefore, the angle 97 degrees and the angle 15 are alternate exterior angles.

Alternate exterior angles are congruent.

Therefore,

∠15 = 97 degrees.

Hence, the measure of ∠15 is 97 degrees.

The best approximate solution to the linear system is  x= 3/4 y = -1

What is linear system?

linear system are system of equations in which the variables are never multiplied with each other but only with constants and then summed up.

Reorder the equation:2x-y =5/2

2x-2y = 7/2

Subtract the two equations:

2x-y -(2x-2y)=5/2 - 7/2

Remove parentheses:

2x-y -2x +2y =5/2-7/2

Cancel one variable:

-y +2y =5/2-7/2

Combine like terms:

5/2-7/2

Write the numerators over common denominator:

Y= 5-7/2

Calculate the sum or difference:-2/2

Rewrite the fraction:-2/2

Cross out the common factor:-1

Substitute into one of the equations:2x-(-1)=5/2

Remove the parentheses:2x+1=5/2

Multiply both sides of the equation by the common denominator:2x×2+2=5×2/2

Reduce the fractions:2x×2+2=5

Rearrange unknown terms to the left side of the equation:4x=5-2

Calculate the sum or difference:4x=3

Divide both sides of the equation by the coefficient of variable:

The solution of the system is:x=3/4

Equation: 7x - 9 = 5 (x+2) 7x - 9 = 5x + 10 2x = 19 x = 9.5

Solving a system of equations, we will see that Suvinder bought 60 of the £0.20 stamps and 40 of the £0.35 stamps.

We know that Suvinder spent £26 on 100 postage stamps, defining:

Then we can write the system of equations:

x + y = 100

x*0.20 + y*0.35 = 26

Isolating x on the first equation we get:

x = 100 - y

Replacing that in the other equation we get:

(100 - y)*0.20 + y*0.35 = 26

Solving that for y, we get:

20 - y*0.20 + y*0.35 = 26

20 + y*0.15 = 26

y*0.15 = 26 - 20 = 6

y = 6/0.15 = 40

Then:

x = 100 - y = 100 - 40 = 60

For the given options, we will find the function that has the greatest rate of change as x approaches infinity

The first function is a linear

The second function is quadratic

The third function is exponential

By reviewing the graph of the three functions, we can know that the exponential function has the greatest rate of change as x approaches infinity

So, the answer will be option C) h(x)

It will take about 8.7 hours until there are 350 bacteria present using exponential growth.

An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.

The formula is as follows:

P = [tex]initial (rate)^x[/tex]

Given that 260 bacteria are placed in a petri dish.

initial value = 260

growth factor = 2

growth factor's associated time period = 26 hours

Exponential growth equation can be written as

[tex]n = 260(2^(t/26))[/tex]

For n=350, we can put the value and take log on both sides.

[tex]350=260(2^{(t/26)} )[/tex]

[tex]1.3 = 2^{t/26}[/tex]

log 1.3 = (t/26) log(2)

26×log(1.3)/log(2) = t

t ≈ 8.7 hours

Therefore, it will take about 8.7 hours until there are 350 bacteria present.

The equation for a line parallel to y = 3x + 2 that passes through the point (2, 1) is y = 3x - 5.

The point slope form is used to calculate the equation of a straight line that is inclined to the x-axis at a given angle and passes through a given point.

Depending on the information available, the equation of a line can be found using a variety of methods. Among the methods are:

The given equation of line is y = 3x + 2.

We need to find the equation of line parallel to the given line and it passes through the point (2, 1).

Slope of line y = 3x + 2 is given as:

By comparing the given equation with y = mx + c, we can say that the slope(m) = 3

Let, a point with coordinates (x, y) be on the line parallel to given line.

Finding slope again we get,

[tex]\frac{y-1}{x-2}[/tex] = 3

y-1 = 3x - 6

∴ y = 3x - 5

As a result, a line parallel to y = 3x + 2 that passes through the point (2, 1) has the equation  y = 3x - 5.

The ages of John, Tom and Lisa are 52 years, 54 years and 68 years respectively.

According to the question,

We have the following details:

The average age of the Bear family is 58 years.

Now, let's take Tom's age to be x years, Lisa's age to be y years and  John's age to be z years.

So, we have the following expression:

(x+y+z)/3 = 58

(x+y+z) = (58*3)

(x+y+z) = 174 .... (1)

Now, John is two years younger than Tom, so we have:

z = (x-2) ....(2)

Lisa is 16 years older than John. So, we have:

y = (z+16) ....(3)

Now, putting the values of y and z in equation 1,

x+z+16+x-2 = 174

Now, again putting the value of z from equation 2,

x+x-2+16+x-2 = 174

3x+12 = 174

3x = 174-12

3x = 162

x = 162/3

x = 54 years

Now, putting the value of x in equation 2,

z = x-2

z = (54-2) years

z = 52 years

Now, putting the value of z in equation 3,

y = z+16

y = (52+16)

y = 68 years

Hence, the ages of John, Tom and Lisa are 52 years, 54 years and 68 years respectively.

The acronym PEMDAS defines the precedence of operations, from highest to lowest, as follows:

For the first item, we want a result of 29, hence the expression will be of:

(6+9)/3+(16-4)*2.

As the equivalent result will be of:

(6+9)/3+(16-4)*2 = 15/3 + 12 x 2 = 5 + 24 = 29.

For the second item, we want a result of 2, hence the expression will be of:
