Answer:

Exact form: [tex]\sin{(6x)} = \frac{8}{9}[/tex]

Decimal form: [tex]\sin{(6x)} = 0.8889[/tex]

The solution for x is: The solution for x is of 10.455º

Step-by-step explanation:

We are given the following equation:

[tex]8 = 9\sin{(6x)}[/tex]

Placing into the desired format, the exact format is:

[tex]\sin{(6x)} = \frac{8}{9}[/tex]

In the decimal part, we divide 8 by 9. So

[tex]\sin{(6x)} = 0.8889[/tex]

Solving for x:

We apply the inverse sine. So

[tex]\sin^{-1}{\sin{(6x)}} = \sin^{-1}{0.8889}[/tex]

[tex]6x = 62.73[/tex]

[tex]x = \frac{62.73}{6}[/tex]

[tex]x = 10.455[/tex]

The solution for x is of 10.455º

Answer:

The 2nd option is correct.

i.e.

y = 10+1, because the rate of change of the graphed function is 3.

Step-by-step explanation:

From the graph,

Taking two points

Finding the rate of change or slope between (0, 0) and (3, 9)

Using the formula

Rate of change = Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [9 - 0] / [3 - 0]

               = 9 / 1  

               = 3

Thus, the rate of change or slope of the line = m = 3

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Considering the function in 2nd option

y = 10x+1

Comparing with the slope-intercept form of the line equation y = mx+b

The rate of change or slope = m = 10

Conclusion:

The rate of change or slope of the graphed line: m = 3

The rate of change or slope of y = 10x+1 is: m = 10

Thus, the rate of change of y = 10x+1 i.e. m = 10 is greater than the rate of change of the graphed line i.e. m = 3.

Hence, the 2nd option is correct.

i.e.

y = 10+1, because the rate of change of the graphed function is 3.

Answer:

it's density is 8 g /cm³

Step-by-step explanation:

Mass (m) = 96 g

Volume (v) = 12 cm³

Density (d) =?

We know density is defined as mass per unit volume so

d = m/v

= 96 / 12

= 8 g/cm³

Hope it will help :)

32=100%

3=3/32 x 100%

=300/32%

=9 3/8%

The percentage to be for 3 students if 32 students make up 100% of the class is 9.375%.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum.

Given:

32 students make up 100% of the class

Calculate the percentage of one student,

1 student = 100 / 32 = 3.125 %

Calculate the percentage of 3 students

3 students =  3.125 × 3 = 9.375%

Therefore, the percentage to be for 3 students if 32 students make up 100% of the class is 9.375%.

Answer:

The ratio of all the adjacent terms is the same and equal to

[tex]r=-4[/tex]

The next three terms after the last one will be:

Step-by-step explanation:

Given the sequence

-4, 16, -64, 256, …

Finding the common ratio

An arithmetic sequence has a constant ratio 'r' and is defined by  

[tex]a_n=a_1\cdot r^{n-1}[/tex]

computing the ratios of all the adjacent terms

[tex]\frac{16}{-4}=-4,\:\quad \frac{-64}{16}=-4,\:\quad \frac{256}{-64}=-4[/tex]

The ratio of all the adjacent terms is the same and equal to

[tex]r=-4[/tex]

Finding the next three terms

Given the sequence

-4, 16, -64, 256, …

here

[tex]a_1=-4[/tex]

[tex]r=-4[/tex]

substituting [tex]a_1=-4[/tex] and [tex]r=-4[/tex] in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=-4\left(-4\right)^{n-1}[/tex]

substituting n = 5 to determine the 5th term

[tex]a_5=-4\left(-4\right)^{5-1}[/tex]

[tex]a_5=-4^4\cdot \:4[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_5=-4^{1+4}[/tex]

[tex]a_5=-4^5[/tex]

[tex]a_5=-1024[/tex]

substituting n = 6 to determine the 6th term

[tex]a_6=-4\left(-4\right)^{6-1}[/tex]

[tex]a_6=-4\left(-4^5\right)[/tex]

[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]

[tex]a_6=4\cdot \:4^5[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_6=4^{1+5}[/tex]

[tex]a_6=4^6[/tex]

[tex]a_6=4096[/tex]

substituting n = 7 to determine the 6th term

[tex]a_7=-4\left(-4\right)^{7-1}[/tex]

[tex]a_7=-4^6\cdot \:4[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

[tex]a_7=-4^{1+6}[/tex]

[tex]a_7=-4^7[/tex]

[tex]a_7=-16384[/tex]

Therefore, the next three terms after the last one will be:

Answer:

99,7 %

Step-by-step explanation:

P [  45,4  <  X  <  64,6 ]   ???

P [  45,4  <  X  <  64,6 ]  

for  X = 45,4

z₁  =  ( X - μ₀  ) / σ

z₁  =  45,4  -  55 / 3,2

z₁  =  - 9,6 / 3,2

z₁  =  - 3

And fom z-table we find     P [ X = 45,4 ]  =  0,0013   or  0,13 %

z₂  = ( 64,6  -  55 )/ 3,2

z₂  =  3

And from  z-table we find     P [ X = 64,6 ]  =  0,9987  or  99,87 %

Then

P [  45,4  <  X  <  64,6 ]  =  99,87  - 0,13  =  0,9974    or  99,74 %

Now if we look at the values:

μ₀   -  3*σ       and     μ₀   +  3*σ  

we find    55  -  3*3,2   =  55 - 9,6  = 45,4  and   55 + 9,6  = 64,6

We know according to the empirical rule that  values from μ₀   ±  3*σ  will contains 99,7 % of all values
