Answer -

  • Given expression -

\frac{4 \sqrt{5} }{3 \sqrt{2} }  \\

<u>we're</u><u> </u><u>required</u><u> </u><u>to </u><u>rationalise</u><u> </u><u>the </u><u>expression</u><u> </u><u>!</u>

<u>therefore</u><u> </u><u>,</u><u> </u><u>we'll</u><u> </u><u>be </u><u>rationalising </u><u>the </u><u>denominator.</u>

\frac{4 \sqrt{5} }{3 \sqrt{2} }  \times  \frac{3 \sqrt{2} }{3 \sqrt{2} }  =  \frac{12 \sqrt{10} }{18}  \\  \\ \implies \:  \frac{\cancel6(2 \sqrt{10}) }{\cancel{18} } \\  \\ \implies \:  \frac{2 \sqrt{10} }{3}

hope this helps !

Solve ln 2 + ln x = 5. Round to the nearest thousandth, if possible.
azamat

Answer:

The  value of x nearest to thousandths is, 74.207

Step-by-step explanation:

Solve :  \ln 2 + \ln x = 5

\ln represents the logarithmic function with base e.

Using logarithmic properties:

  • \ln (mn) = \ln m + \ln n
  • \ln x = a , then x = e^a

\ln 2 + \ln x = 5

Apply the logarithmic properties; we have

\ln 2x = 5

then;

2x = e^5

or

2x=148.41315910258

Divide both sides by 2 we get;

x = 74.2065796

Therefore, the value of x nearest to thousandths is, 74.207

The measures of the base angles of an isosceles triangle are 3x 5 and 5x - 25. The measure of the vertex angle is 6x - 10. Find
lukranit [14]

Answer: The measure of the vertex angle = 80°

Step-by-step explanation:

Angle sum property of triangle : The sum of the measures of the angles for any triangle is 180 degrees.

So,

3x+ 5 + 5x-25+6x-10= 180\\\\\Rightarrow\ 14x-30=180\\\\\Rightarrow\ 14x= 210\\\\\Rightarrow x=\dfrac{210}{14}=15'

Then, vertex angle = 6(15)-10=90-10= 80

Hence, The measure of the vertex angle = 80°

For students who first enrolled in two year public institutions in a recent​ semester, the proportion who earned a​ bachelor's d
kondaur [170]

Answer:

Null hypothesis =  H_0:p=0.395

Alternate hypothesis =H_a:p>0.395

Step-by-step explanation:

Given : In a recent​ semester, the proportion who earned a​ bachelor's degree within six years was 0.395.

The president of a certain college believes that the proportion of students who enroll in her institution have a higher completion rate.

To Find : Determine the null and alternative hypotheses.

Solution:

In a recent​ semester, the proportion who earned a​ bachelor's degree within six years was<u> 0.395. </u>

Claim : the proportion of students who enroll in her institution <u>have a higher completion rate.</u>

So,null hypothesis =  H_0:p=0.395

Alternate hypothesis =H_a:p>0.395

0.85 in fractional notation
artcher [175]
If you would like to write 0.85 in a fractional notation, you can do this using the following steps:

0.85 = 85/100 which simplifies to 17/20 <span>(the common factor of 85 and 100 is 5, so you can divide both numbers by 5).

The correct result would be 17/20.</span>

(-8) - 3y= 25<br><br>if you have time please help, thank you​
Neko [114]

(-8) - 3y= 25

-8-3y= 25

move -8 to the other side

sign changes from -8 to +8

-8+8-3y=25+8

-3y= 33

divide both sides by -3 to get y by itself

and to get +y

-3y/-3= 33/-3

Answer:

y= -11
