Answer: To find the limit as x approaches 16, we can substitute x = 16 into the expression:

lim (4-√X)/16X-X² = (4 - √16)/16 * 16 - 16^2 = (4 - 4)/16 * 16 - 256 = 0/256 - 256 = -256.

So the limit as x approaches 16 is -256.

Answer:

  (a)  y = x/3 -1

Step-by-step explanation:

You want the equation of the line graphed showing points (3, 0) and (6, 1).

The slope of the line is its "rise" divided by its "run." Here, the points are 3 units apart horizontally, and 1 unit vertically, with the line going up to the right. That means ...

  slope = rise/run = +1/+3 = 1/3

The slope-intercept form of the equation for a line is ...

  y = mx +b . . . . line with slope m and y-intercept b

The slope of 1/3 means the coefficient of x will be 1/3. There is only one answer choice like that:

  y = x/3 -1

The proof is given as follows:

The transitive property argues that "if two quantities are equal to the third quantity, then we may claim that all the quantities are equal to one other".

The term transitive refers to a transfer. If there are three quantities a, b, and c, and if an is connected to b by some rule and b is related to c by the same method, then a and c are related to each other by the same rule; this property is known as the transitive property of equality.

The solution to the equation -1/5 = -2y + 8/5 is y = 9/10

Given the equation in the question;

-1/5 = -2y + 8/5

First, rewrite the equation as;

-2y + 8/5 = -1/5

Move all terms not containing y to the right side of the equation

-2y + 8/5 - 8/5 = -1/5 - 8/5

-2y = -1/5 - 8/5

Add  -1/5 and -8/5

-2y = ( -1 - 8) / 5

-2y = -9 / 5

Divide both sides by -2

-2y / -2 = -9/5 ÷ -2

y = -9/5 × -1/2

y = 9/10

Therefore, the value of y is 9/10.

Therefore , the solution of the given problem of mean comes out to be

23.679 the isotopic mass of the least abundant isotope.

The arithmetic mean, often known as the average, of a dataset is the total of all values divided by the number of values (as opposed to the geometric mean). It is the most used often index of central tendency, sometimes known as the "mean." This result can be obtained by simply dividing the number of variables values in the dataset by the sum of all the values.

Here,

The abundant isotope has an isotopic mass of 123.39 u, compared to the most prevalent isotope's mass of 121.560 u.

22.567 u is the average atomic mass.

84.236% is the most prevalent isotope.

22.653 u is the isotope's mass.

Least prevalent isotope: 100 - 84.236% = 15.764%

Take into account that x is the mass of both the least common isotope.

The same element's atoms called abundant isotopes have different quantities of neutrons than other isotopes. These species always have the same number of protons and electrons. Although there is a change in the number of neutrons, the atomic number is unaffected. The weighted value of all the isotopes that an element naturally presents is its atomic mass.

Average atomic mass is equal to the sum of the natural abundances of the isotopes A and x divided by 100.

=> 22.653 = ( 22.567 * 84.236) + (x * 15.764 ) / 100

=>22.653 * 100 = 1900.953 + 15.764 x

=> x = 22.653 * 100 - 1900.953/ 15.764

=> 23.679

There are 4 kilograms of type B in one bag of the blend.

What is a linear equation in one variable?

A linear equation in one variable is an equation that can be written in the form ax + b = 0, where a and b are constants and x is the variable. This equation represents a straight line in a coordinate plane and the solution to the equation corresponds to the x-coordinate of the point where the line intersects the x-axis.

Let's call the amount of type B in one bag of the blend "x".

Since one bag of the blend is 4 kilograms of type A, we know that one bag is 4 + x kilograms of coffee.

And since 6 bags of the blend is a total of 48 kilograms, we can write an equation:

6 * (4 + x) = 48

Expanding the left-side of the equation:

24 + 6x = 48

Subtracting 24 from both sides:

6x = 24

Dividing both sides by 6:

x = 4

Hence, there are 4 kilograms of type B in one bag of the blend.

The amount spent by the friend is $909.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 8 is an equation.

We have,

Amount spend for 32 tickets = $3,232

Cost of parking = $25

Let p represent the amount the fan paid for each ticket.

The cost of each ticket.

P + 25 = 3,232/32

P = 101 - 25

P = $76

Answer:

(x - 1)² + (y - 1)² = 25

Step-by-step explanation:

the distance from the center of the circle to any point on the edge (or arc) of the circle is the radius of the circle.

per the distance formula (= Pythagoras for the right-angled triangle of the coordinate differences between the 2 points) we know

AB² = (xb - xa)² + (yb - ya)² = (5 - 1)² + (4 - 1)² =

= 4² + 3² = 16 + 9 = 25

AB = radius = 5

the standard form of a circle is

(x - h)² + (y - k)² = r²

(h, k) being the coordinates of the center of the circle, r being the radius.

(x - 1)² + (y - 1)² = 25

is the correct equation.

By solving a system of equations, wewill see that they sold 325hamburgers.

Let's define the variables:

h = number of hamburgers.

c = number of cheeseburgers.

We know that the total combined number is 588, then we can write:

h +c = 588

And there were 62 fewer cheeseburers than hamburgers, then:

c = h - 62

Now we have a system of equations:

h +c = 588

c = h - 62

c is already isolated on the second equation, so we can replace that on the first equation to get:

h + (h - 62) = 588

2h = 588 + 62

2h = 650

h = 650/2 = 325

They sold 325 hamburgers.

The equation of the line passing through the point (-4, 1), and having a slope of m = -3/2 is 2y = -3x - 10.

The slope of the line and a point on the line can be used to create the equation of a line. To better comprehend how the equation for a line is formed, let's learn more about the line's slope and the necessary point on the line. The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis. The coordinate system's point with the x coordinate and the y coordinate is referred to as the point.

The equation of the line passing through the points (x1, y1), with a slope of m is given by the formula:

(y - y1) = m (x - x1)

Given that the point is (-4, 1) and the slope, m = -3/2.

Substituting the values we have:

(y - y1) = m (x - x1)

y - 1 = -3/2 (x - (-4))

2(y - 1) = -3(x+ 4)

2y - 2 = -3x - 12

2y = -3x - 10

The inequality to compare the number of pictures taken during school to the number of pictures taken after school is: 19 < 24.

Step-by-step explanation:

Here's a step-by-step explanation of the inequality comparison:

Start with the two values being compared: 19 pictures taken during school and 24 pictures taken after school.

Use the inequality symbol (<) to compare the two values: 19 < 24.

Read the inequality as "19 is less than 24". This means that there were fewer pictures taken during school (19) than after school (24).

So the inequality comparison between the number of pictures taken during school and after school is: 19 < 24.

It took 3 hours to travel 150 miles with a speed of 50 miles per hour.

The speed of an object tells how fast or slow an object will cover a distance in the time period. The speed of an object is directly proportional to the distance covered by the object and will be inversely proportional to time.

Here we have

A drive of 50 miles per hour between Seattle and Portland
which are 150 miles apart  

Given speed = 50 miles per hour

Distance covered = 150 miles  

The time is taken to travel the distance, Time = Distance / Speed
