Which of the following logarithmic expressions have been evaluated correctly?
A. ln 1=0
B. log2 9=3
C. log 1/100=12
D. log3 (−1)=1/3
E. log5 1/125=−3

Answers

Answer 1

The correctly evaluated logarithmic expressions are expressions that are true on both sides of the equation, and the expression is ln 1=0

How to determine the correctly evaluated expressionsA. ln 1=0

As a general rule, ln 1 = 0

B. log2 9=3

Express 9 as 3^2

[tex]\log_2(3^2) =3[/tex]

Apply the law of logarithm

[tex]2\log_2(3) = 3[/tex]

Evaluate

[tex]3.17 = 3[/tex]

The above is not true

C. log 1/100=12

Express 1/100 as 10^-1

[tex]\log(10^{-2}) = 12[/tex]

Apply law of logarithm

[tex]-2\log(10) = 12[/tex]

Evaluate

[tex]-2 = 10[/tex]

The above is not true

Options (d) and (e) are also false

Hence, the correctly evaluated logarithmic expressions is ln 1=0

Suppose that under your health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay. You get sick and are hospitalized for 4 days, and the bill (after your insurance discounts are applied) comes to $6,250. How much of that hospital bill will you have to pay yourself?

Answers

Answer:

$4900

Step-by-step explanation:

It is given that,

According to health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay.

If a person hospitalized for 4 days, it would mean that charges will be ($150 × 4 = $600 per day).

Total amount given by insurance policy = $750 + $600 = $1350

The bill for 4 days come out to be $6,250.

The person have to pay ($6,250-$1350) = $4900 itself.

Answers

Answer:

Part A - Yes; y=5/3w        Part B - No; e=h+2

Step-by-step explanation:

The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.

Cara’s Flower Arrangements            Proportional

White 3 6 9 12 15

Yellow 5 10 15 20 25

Hector’s Flower Arrangements          Not Proportional

White 4 8 12 16 20

Part A

Are the numbers of white and yellow flowers in Cara’s arrangements proportional?

Which equation relates the number of white flowers, w, to the number of yellow flowers, y?

Yes; y=3/5w

Yes; y=5/3w CORRECT ANSWER

No; y=3w+5w

No; y=5+3w

Part B

Are the numbers of white and yellow flowers in Hector’s arrangements proportional?

Which equation relates the number of white flowers, h, to the number of yellow flowers, e?

Yes; e=3/2h

Yes; e=2/3h

No; e=h+2 CORRECT ANSWER

No; e=h−2

They are correct because Part A is 1.666667  thats more than 1 so it cant be the first, and Part B, its the White flowers plus 2 to be Yellow flowers, not -.

Following are the solution to the given question:

Using the proportionate connection theory to model these two tables, we may conclude the first table is proportionate whereas the second is not.Clara's configuration:

                   [tex]\bold{White (w) }\\\\\bold{Yellow (y)}[/tex]

To determine whether a relationship is proportionate, perform the following tests:

                    [tex]\bold{y = kw } \\\\\bold{5 = 3k}[/tex]

Yes, there seems to be a proportional relationship. Hector's set-up is as follows:

                  [tex]\bold{White (h) }\\\\\bold{Yellow (e)}\\\\[/tex]

The number of yellow flowers always out-numbers the number of white blooms by a factor of 2. As a result, the relationship could be modeled as follows;

               [tex]\to \bold{e = h + 2}[/tex]

As a result, the relationship is not proportionate.

If the value the discriminant is exactly 0, what is true about the graph of the quadratic equation?

Answers

A discriminant of zero means the quadratic equation has one real root. In other words, the only part of the parabola touch the x axis is the vertex. The vertex is the bottom of the parabola.

An example is provided in the attached picture

The truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.

What is a quadratic equation?

The quadratic equation is defined as a function containing the highest power of a variable is two.

When discriminant D of a quadratic equation,

D = 0

Roots are equal and real

D > 0

Roots are real and different

D < 0

Roots have not existed.

When the discriminant is zero, there is only one real root to the quadratic equation. In other words, only the vertex of the parabola connects the x-axis. The vertex is the parabola's base.

Therefore, the truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.

Joan charges a $3 fee plus $4 per hour.
When will their tutoring fees be the same (aka equal)
How many hours of tutoring will occur before the fees are the same?
How much has each person been paid in tutoring fees?

Answers

Answer:

after 2 hours, they will have the same fee.

they will have been payed 11$

Step-by-step explanation:

if you say  h = hours of tutoring,

Rakim charges 7 + 2h

Joan charges 3 + 4h

since you want them to be the same, you can write the following equation:

7 + 2h = 3 + 4h

subtract 2h from each side

7 = 3 + 2h

subtract 3 from each side

4 = 2h

divide both sides by 2.

h = 2

after 2 hours, they will have the same fee.

they will have been payed 11$

"they will have been payed" ah yes the grammar.

If a translation is described as (x -5, y), how has the original image changed?

Answers

Answer:

It moves the x value 5 units to the left.

Step-by-step explanation:

"x - 5" means that we are subtracting 5 to whatever x value we are given. The "y" value doesn't change.

Since we are subtracting to the x value, we are going to move left 5 units.

Let's say we had the point (5, 5).

If we use the translation rule;

(5 - 5, 5)

(0, 5)

We moved the x value 5 units to the left.

What’s the question???

Do these pairs of values (x and y) represent two quantities that are
proportional?
A. Yes, because as x increases, y increases.
B. No, because not all of the pairs represent the same ratio.
C. Yes, because the ratios į and i are equal.
O D. No, because not all of the pairs are simplified ratios.

Answers

Answer: B) No, because not all of the pairs represent the same ratio

For each row, divide y over x

Row 1:  y/x = 5/3 = 1.67 approximately

Row 2: y/x = 7.4 = 1.75

Row 3: y/x = 10/6 = 1.67 approximately

Row 4: y/x = 15/9 = 1.67 approximately

We see that row 2 has a ratio different from the others. If we were able to ignore this row, then the answer would be "yes x and y are proportional". However, we cannot ignore this row so that's why the answer is choice B.

We want to see if the relationship between x and y is proportional or not.

We will see that the correct option is B:

"No, because not all of the pairs represent the same ratio."

Let's see how to solve this.

First, a proportional relationship is something of the form:

y = k*x

Where k is the constant of proportionality.

So to see if the relationship between x and y is proportional, we can input the pairs on the general proportional relationship.

For the first pair, we have x = 3 and y = 5, then:

5 = k*3

Now we can find the value of k:

k = 5/3 = 1.667

Now let's do the same for the second pair of points, we should get the same constant of proportionality.

7 = k*4

k = 7/4 = 1.75

So we got different constants of proportionality for two different x-y pairs, thus, the relationship is not proportional.

Because k is defined as the ratio between y and x, we can say that the relationship is not proportional because not all of the pairs represent the same ratio.

Thus the correct option is B.

A circle totals to 360°.

If we add what we are given; 295 + 23 = 318°

We have the total angle measure we are given and "b" which we need to solve.

We can subtract 360 by what we are given to find angle "b"

360 - 318 = 42°
