Why are radicals simplified before adding and subtracting? Explain your reasoning by adding the square root of 8 and the square

Rashid [163]

The reason they have to be simplified is that you cannot add radical unless the number under the radical is the same on all of them.

For example:

If you add √8 + √32 without simplifying, the best you could do is an estimate. But if you're required to put your answer in standard radical form this would be an issue.

So, you would have to simplify to combine:

√4√2 + √16√2
2√2 + 4√2
6√2

Hope this helped!

Helpppppppppppppppppp

Hey there! :D

When there are two lines (parallel) that are cut by a transversal, corresponding angles form. These are angles that are in the same position on the same side. m<2 is corresponding to the angle that equals 38 degrees. They are congruent and have the same measure.

m<2= 38 degrees

Remember, this only works because the problem said that line L and M are parallel.

I hope this helps!

Can u guys PLEASE answer the depreciation question ASAP. THIS IS URGENT!

Furkat [3]

Answer: the value of the car after 7 years is $11220

Step-by-step explanation:

The formula for determining depreciation is expressed as

A = P(1 - r)^t

Where

A represents the final value of the car after t years.

P represents the present value of the car.

r represents the rate of depreciation

t represents the number of years.

From the information given

P = 35000

r = 15% = 15/100 = 0.15

t = 7 years

Therefore,

A = 35000(1 - 0.15)^7

A = 35000(0.85)^7

A = 11220.198

Rounding up yo the nearest dollar, it becomes $11220

A television newscaster from a 24-hour news station wants to estimate the number of hours per day its viewers watch

Answer:

This isn't the best worded question but from what I understand a larger sample size decreases the margin of error. If he would like a more accurate answer a larger sample size of the viewers will give more accurate answers.

Dada la ecuacion 25x2 + 4y2 = 100, determina las coordenadas de los vertices, focos, las longitudes de los respectivos ejes mayo

Likurg_2 [28]

Answer:

The given equation is

$25x^{2} +4y^{2}=100$

Which represents an elipse.

To find its elements, we need to divide the equation by 100

$\frac{25x^{2} +4y^{2} }{100} =\frac{100}{100} \\\frac{x^{2} }{4} +\frac{y^{2} }{25} =1$

Where $a^{2} =25$ and $b^{2}=4$ . Remember that the greatest denominator is $a$ , and the least is $b$ . So, we extract the square root on each equation.

$a=5$ and $b=2$ .

In a elipse, we have a major axis and a minor axis. In this case, the major axis is vertical and the minor axis is horizontal, that means this is a vertical elipse.

The length of the major axis is $2a=2(5)=10$ .
