Write an equation that has two radical expressions and no real roots.

Answers

Answer 1

[tex]\sqrt{x}[/tex] = [tex]\sqrt{x+1}[/tex] has no real roots.

[tex]\sqrt{x}[/tex] = [tex]\sqrt{x+1}[/tex]

squaring both the sides

x = x+1

0 = 1

which is not true

hence false.

Therefore, no real roots.

Each time she ran the dishwasher it cost her $0.09 for water and $0.13 for electricity. What was the lifetime cost of Ellen's dishwasher? a. $1,030.44 b. $686.40 c. $1,093.73 d. $749.69 Please select the best answer from the choices provided. A B C D

Answers

The lifetime cost of Ellen's dishwater is $1,030.44

What is Number system?

A system of writing to express the number is called number system.

Given that;

Cost of dishwasher before sales tax 9.22% is = $315

And, Sales tax = 9.22%

Hence, Total cost = 315 *( 1 + 0.0922) = 315 * 1.0922 = 344.043

And, Average of 10 times per week for the next 6 years before replacing it.

Since, There are 52 weeks in a year.

So, Average uses is calculated as,

10  * 52  * 6 = 3120

Since, cost for water = $0.09

Cost for electricity = $0.13

Total cost per uses = $0.22

Hence, Cost of uses = 0.22 * 3120 = $686.40

Now, Purchase cost = $344.043

And, Cost of uses =  $686.40

Hence, Lifetime cost =  $344.043 + $686.40 = $1,030.443

So, The lifetime cost of Ellen's dishwater is $1,030.44.

Aisha organized her books for 1/6 and her coin collection for 3/7.

What's the best estimate for the total Aisha spent organizing?

(Brainliest Question)

Answers

The best estimate for the total Aisha spent organizing is; 1/2 hour

How to estimate fractions?

We are told that Aisha organized her books for 1/6 and her coin collection for 3/7.

Now, normally when we want to find the total, we just add both fractions in this manner;

1/6 + 3/7 = 25/42

Now, since we want to find the best estimate, we will just approximate each fraction individually to get;

1/6 hour is closer to 0 hours than 1/2 hour. Thus;

1/6 hr ≈ 0 hour

3/7 hour is closer to 1/2 hour than 0 hours. Thus;

3/7 hr ≈ 1/2 hour

Thus;

Best estimate for total spent = 0 + 1/2 = 1/2 hour

Is the above relationship a linear function?

The table of values is given as

A linear relationship is any relationship with a constant rate

From the above table, we can see that as x increases by 1, y decreases by 3

This means that

Slope = Rate = -3

Hence, the relationship a linear function

In (a), we have

Slope = -3

Also, we have

Number of Clubs      Free Time (hours)

Reduce the above parameters by the constant rate

So, we have

Number of Clubs      Free Time (hours)

0                                      24

1                                         27

The above means that

y-intercept = 24

M bisects PQ. PM=9x + 3 and MQ= 11x -17, find x.

Answers

Applying the definition of a midpoint, the value of x is calculated as: x = 10.

What is the Midpoint of a Segment?

The midpoint of a segment, for example, point M, is a point that bisects a segment into two equal parts with the same measurement.

Thus, this means that:

PM = MQ

PM = 9x + 3

MQ = 11x - 17

Substitute

9x + 3 = 11x - 17

Combine like terms

9x + 3 - 11x = 11x - 17 - 11x

-2x + 3 = -17

-2x + 3 - 3 = -17 - 3

-2x = -20

Some of the important formulas in logarithm are:

loga where a is considered as base of the logarithm and b is the argument

is given as nlogab

when base and the argument is same , log is given as 1

logabc where a is the base is given as logab+logc

loga b/c where a is the base is given as logab-logac

Now it is given to us to find the logarithmic form of 36=6^2
