Answer:

(x+2-5y^2) (x+2+5y^2)

Step-by-step explanation:

......,....................

Given:

[tex]4,4+2x,4+4x[/tex] are in geometric sequences​.

To find:

The value of x.

Solution:

If a, b, c are in geometric sequences​, then

[tex]\dfrac{b}{a}=\dfrac{c}{b}[/tex]

[tex]b^2=ac[/tex]           ...(i)

It is given that [tex]4,4+2x,4+4x[/tex] are in geometric sequences​. By using (i), we get

[tex](4+2x)^2=(4)(4+4x)[/tex]

[tex]4^2+2(4)(2x)+(2x)^2=(4)(4)+4(4x)[/tex]

[tex]16+16x+4x^2=16+16x[/tex]

[tex]4x^2=16+16x-16-16x[/tex]

On further simplification, we get

[tex]4x^2=0[/tex]

[tex]x^2=0[/tex]

[tex]x=0[/tex]

Therefore, the value of x is 0.

Yup that's a scientific number alright.

Answer:

Step-by-step explanation:

The scientific notation 1019e-9 is same as 1019×10^-9 or 1019×10-9. Thus, to get the answer to 1019e-9 as a decimal, we multiply 1019 by 10 to the power of -9.

Answer:

15. 6

16. 40

Step-by-step explanation:

Use the formula for pythagorus: c^2 = a^2 + b^2

15. 10^2 = 8^2 + b^2

100 = 64 + b^2

*minus 64 on both sides

36 = b^2

*square root both sides

b = √36 = 6  

16. c^2 = 24^2 + 32^2

c^2 = 576 + 1024

c^2 = 1600

*square root both sides

c = √1600 = 40

Hope this helps :)

1) 164

2) 1600

because a^2 + b^2 = c^2 <3

Answer:

12%

Answer:

a = 241

b = 71

Step-by-step explanation:

a + b = 312 (#1)

a - b = 170 (#2)

(#1) + (#2) = 2a = 482.

a = 482 / 2 = 241.

b = 312 - 241 = 71.

Answer:

Angle 1= 106° and Angle 2=74°

Step-by-step explanation:

Angle 2 is 74° because lines a and b are parallel, and since there is a transversal, the 74° angle and angle 2 are corresponding angles.

Angles 1 and angle 2 are supplementary, so you would just do 180° - 74° and you get 106°

Given:

Amount = Rs. 34476

Rate of compound interest = 4%

Time = [tex]2\dfrac{1}{2}=2.5[/tex] years

To find:

The principal value.

Solution:

Formula for amount is

[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]

Where, P is principal value, r is rate of interest and t is time in years.

Putting the given values, we  get

[tex]34476=P\left(1+\dfrac{4}{100}\right)^{2.5}[/tex]

[tex]34476=P\left(1+0.04\right)^{2.5}[/tex]

[tex]34476=P\left(1.04\right)^{2.5}[/tex]

[tex]\dfrac{34476}{\left(1.04\right)^{2.5}}=P[/tex]

Now,

[tex]P=31256.0090[/tex]

[tex]P\approx 31256[/tex]

Therefore, the value of sum or principal value is Rs.31256.

Answer:

Determine the proportion of months where memberships sold decreases,

increases and remained the same.

Step-by-step explanation:

I just took the test and got it correct.

The first step needed to simulate this data is:

Assign each month a digit from 1 to 24 to account for the 24 total months being compared.

Option B is the correct answer.

Simulating data means creating artificial data that mimics the characteristics of real data.

This artificial data is generated by using a model or a set of rules that describe how the data might be generated under certain conditions.

We have,

The first step needed to simulate this data is to assign each month a digit from 1 to 24 to account for the 24 total months being compared.

This will allow for an easy comparison of the sales data from last year and this year.

Once each month has been assigned a digit, the data can be organized and analyzed to determine the proportion of months where memberships sold decreased, increased, and remained the same, as well as the mean monthly sales from last year and this year.

Finally, random digits can be assigned to each sales figure from last year and this year to create a simulated data set that can be used for further analysis and modeling.

Thus,

The first step needed to simulate this data is:

Assign each month a digit from 1 to 24 to account for the 24 total months being compared.
