Graph The Logarithmic Function Below By Moving Thekey Point.y = Log (x)You Can Only Graph Integer Points

Answers

Answer 1

To graph the logarithmic function y = log₂(x), we can use the key point (1,0) and the fact that the logarithmic function is the inverse of the exponential function y = 2ˣ.

Starting at the key point (1,0), we can move to the right by increasing x by a factor of 2, since log₂(2) = 1. This takes us to the point (2,1). Similarly, we can move to the right by a factor of 2 again to get to the point (4,2), and then to (8,3), (16,4), and so on.

If we instead move to the left from the key point (1,0) by a factor of 2, we get to the point (1/2, -1), since log₂(1/2) = -1. We can continue moving to the left by dividing x by 2 to get to (1/4, -2), (1/8, -3), and so on.

The given graph of y = log₂(x) using only integer points.

The graph is symmetric about the line x=1, since log₂(x) = log₂(1/x) = -log₂(x).

19/258 = 21/?

help pls

Answers

Answer:

285.15

Step-by-step explanation:

Given the expression;

19/258 = 21/x

We are to find the unknown value x;

Cross multiply;

19 * x = 258 * 21

19x = 5418

Divide both sides by 19;

19x/19 = 5418/19

x = 285.15

Hence the unknown value is 285.15

The value of sallys caravan decreased by x% in the third year. At the end of the third year the value of sallys caravan was £16,500. Work out the value of x

Answers

The value of x is 100 - 1650000/y where the initial value of the Sally's caravan be represented by y

How to work out the value of x?

The given parameters are

New value = £16,500

Rate of decrease = x%

Let the initial value of the Sally's caravan be represented by y

So, we have the following equation

Initial value  * (1 - Rate of decrease) = New Value

This gives

y * (1 - x%) = 16,500

Divide both sides of the equation by y

So, we have

1 - x% = 16500/y

This gives

x% = 1 - 16500/y

Multiply through by 100

x = 100 - 1650000/y

Hence, the value of x is 100 - 1650000/y where the initial value of the Sally's caravan be represented by y

Use the equation to predict how many glasses with 9
pieces of bling Bella can expect to sell. Do not round.
Input your answer. Then click done.

Answers

Answer:

Bella can sell 13.78 glasses with 9 pieces of bling.

Step-by-step explanation:

Given the function

y=1.36x+1.54

As pieces of the bling are represented on the x-axis, and the number of glasses is represented on the y-axis.

Given that the number of pieces of bling = x = 9

Thus,

[tex]y = 1.36x+1.54[/tex]

 [tex]= 1.36(9)+1.54[/tex]

 [tex]=12.24+1.54[/tex]

 [tex]=13.78[/tex]

Thus, Bella can sell 13.78 glasses with 9 pieces of bling.

On which interval(s) is the function f(x) = x3+3x^2−4x−12 increasing?

Answers

The intervals over which the function is increasing are -

x ∈ (- ∞, - 2.5) and  x ∈ (0.5, ∞). We can write it as one single set (S) as -

S = (- ∞, - 2.5) ∪ (0.5, ∞).

What is increasing or decreasing interval of a function?

The interval in which the y - coordinate of the points gets larger, or the graph gets higher as it moves from left to right over the interval is called increasing interval. Similarly, the interval in which the y - coordinate of the points gets smaller or the graph gets lower as it moves from left to right over the interval is called decreasing interval.

Given is the following function f(x) -

f(x) = x³ + 3x² - 4x - 12

First, we will plot the graph of this function. The graph is attached with the answer. On the graph, there are two black dots. From the definition of increasing functions, we know that the interval along which the y - coordinate gets larger is called increasing interval of the function. The first interval over which the function is increasing is-  x ∈ (- ∞, - 2.5). The second interval over which the function is increasing is- x ∈ (0.5, ∞).

Therefore, the intervals over which the function is increasing are -

x ∈ (- ∞, - 2.5) and  x ∈ (0.5, ∞). We can write it as one single set (S) as -

S = (- ∞, - 2.5) ∪ (0.5, ∞).

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

Let x represent number of mines and y represent the number of gems. Since this is a proportional relationship, hence:

y = kx; where k is the constant of proportionality

From the table when y = 4, x = 1, hence:

4 = k(1)

k = 4

y = 4x

The constant of proportionality is 4, while the equation is given as y = 4x.

some two step equations can be written in the form ax+b=c where a b and c are constants and x is the varible A. write the equation ax+b=c in terms of x B use the formula to solve 3x+7=19 and 1/2x - =5

Answers

A. The equation for x is c - b/a

B. x = 4

x = 10

How to determine the equation

Given the equation;

ax + b  = c

Let's make 'x' the subject of formula by expressing it in terms of other variables

We have;

ax = c - b

Divide both sides by the coefficient of 'x'

ax/a = c - b/ a

x = c - b/a

B. 3x + 7 = 19

Let's solve for x

3x = 19 - 7

3x = 12

Make 'x' the subject

x = 12/ 3

x = 4

1/2x  = 5

cross multiply

x = 5 × 2

x = 10

Thus, the equation for x is c - b/a

An airplane crosses the Atlantic Ocean​ (3000 miles) with an airspeed of 600 miles per hour. The cost C​ (in dollars) per passenger is given by...

​(a) What is the cost per passenger for quiescent​ (no wind)​ conditions?

Answers

The cost per passenger for quiescent (no wind) conditions is $252.33.

How to illustrate the information?

It should be noted that based on the information given, the cost function that was illustrated in the question is:

C(x) = 175 + x/25 + 32000/x

In this case, it should be noted that the airplane crosses the Atlantic Ocean with an airspeed of 600 miles per hour.

Therefore, the cost per passenger for quiescent conditions will be:

C(x) = 175 + x/25 + 32000/x

where x = 600

C(x) = 175 + x/25 + 32000/x

C(x) = 175 + 600/25 + 32000/600

C(x) = 175 + 24 + 53.33

C = $252.33

Therefore, the cost per passenger for quiescent (no wind) conditions is $252.33
