Option B: [tex]x=\frac{8}{3}[/tex] is the solution

Explanation:

The given expression is [tex]\log _{2} 9 x-\log _{2} 3=3[/tex]  

We need to determine the solution for the given expression.

The solution can be determined by solving the expression for x.

Adding [tex]\log _{2} 3[/tex] to both sides of the expression, we have,

[tex]\log _{2}9 x=3+\log _{2}3[/tex]

Using the logarithmic definition that if [tex]\log _{a}(b)=c[/tex] then [tex]b=a^{c}[/tex]

Thus, we have,

[tex]9 x=2^{3+\log _{2}3}[/tex]

[tex]9 x=2^{3}\cdot 2^{\log _{2}3}[/tex]

Simplifying, using the identity [tex]a^{\log _{a}(b)}=b[/tex], we have,

[tex]9 x=8\cdot 3[/tex]

Multiplying, we get,

[tex]9x=24[/tex]

Dividing both sides by 9, we have,

[tex]x=\frac{24}{9}[/tex]

Simplifying, we have,

[tex]x=\frac{8}{3}[/tex]

Thus, the solution of the expression is [tex]x=\frac{8}{3}[/tex]

(-1.2,-2.0) and (1.9,2.2) are the best approximations of the solutions to this system.

Option B

Step-by-step explanation:

Here, we have a graph of two functions from which we need to find the approximate value of common solutions. Let's find this:

First look at where we have intersection points, In first quadrant & in third quadrant.

At first quadrant:

Draw perpendicular lines from x-axis & y-axis from this point . After doing this we can clearly see that the perpendicular lines cut x-axis at x=1.9 and y-axis at y=2.2. So, one point is (1.9,2.2)

At Third quadrant:

Draw perpendicular lines from x-axis & y-axis from this point. After doing this we can clearly see that the perpendicular lines cut x-axis at x=-1.2 and y-axis at y=  -2.0. So, other point is (-1.2,-2.0).

Population of Egypt in 2005 is 72.64 million.

Step-by-step explanation:

We have ,The estimated population of Egypt in 2011 is about 81 million. this is a 1.8% growth rate over the previous year. According to question , population in year 2010 = population in year 2011 - 1.8% of population in year 2011 i.e.

population in year 2010 = [tex]81 - \frac{81(1.8)}{100}[/tex] =  79.52 million

Similarly, population in year 2009 = [tex]79.52 - \frac{79.52(1.8)}{100}[/tex] = 78.10 million

population in year 2008 = [tex]78.10 - \frac{78.10(1.8)}{100}[/tex] = 76.70 million

population in year 2007 = [tex]76.70 - \frac{76.70(1.8)}{100}[/tex] =  75.32 million

population in year 2006 = [tex]75.32 - \frac{75.32(1.8)}{100}[/tex] =  73.97 million

population in year 2005 = [tex]73.97 - \frac{73.97(1.8)}{100}[/tex] = 72.64 million

Therefore, population of Egypt in 2005 is 72.64 million.

Final answer:

To find Egypt's population in 2005 given a 1.8% annual growth rate and a 2011 population of 81 million, we rearrange the exponential growth formula and calculate backward, resulting in an estimated population of approximately 74.8 million in 2005.

Explanation:

The question involves calculating the population of Egypt in 2005, given its estimated population of 81 million in 2011 and an annual growth rate of 1.8%.

To find the population in 2005, we use the formula for exponential growth: P = [tex]P_oe^{rt[/tex],

where P is the future population, P₀ is the initial population, r is the growth rate, t is the time in years, and e is the base of the natural logarithm.

However, in this scenario, since we are calculating backward and we know the future population,

we rearrange the formula to find the initial population: P₀ = [tex]\frac{P}{e^{rt}}[/tex]

Using a growth rate of 1.8% (or 0.018 as a decimal) over 6 years (from 2005 to 2011), the formula becomes:

P₀ = [tex]\frac{81 \text{ million}}{e^{0.018*6}}[/tex]

After calculation, we find that the population of Egypt in 2005 would be approximately 74.8 million.

Answer:

Jen has 12 stamps.

Step-by-step explanation:

Answer: Jen has 27 stamps

Step-by-step explanation:

Let the number of stamps Jack has be y.

Since Jen has 3times of Jack stamps, Jack's stamp is 3×y which is 3y.

Jack's stamp+Jen's stamp= 36

y+3y = 36

4y = 36

y = 9

So Jack has 9 stamps and Jen has 9×3 which is 27 stamps.

Final answer:

Evelyn initially has $7, and after Liz gives her a $5 bill and two $1 bills, Evelyn's total money becomes $14.

Explanation:

The question asks us to calculate how much money Evelyn has after Liz gives her additional cash. Initially, Evelyn has $7. Liz gives her one $5 bill and two $1 bills. To find out the total amount of money Evelyn has now, we simply need to add the amounts together:

Original amount Evelyn has: $7
Liz gives her: 1 x $5 bill = $5
Plus: 2 x $1 bills = $2
Total amount after receiving money from Liz: $7 + $5 + $2 = $14

Therefore, Evelyn now has a total of $14.

Answer:

h = S - 2πr²     /2πr

Step-by-step explanation:

Marta is solving the equation S = 2πrh + 2πr2 for h. Which should be the result?

To solve;

S = 2πrh + 2πr²

The first thing to do is to subtract 2πr²  from both-side of the equation

S - 2πr²  =   2πrh  +  2πr² - 2πr²

S - 2πr²  =   2πrh

Then next is to divide both-side of the equation by 2πr

S - 2πr²  /  2πr  =  2πrh /2πr

On the right-hand side of the equation 2πr at the numerator will cancel-out 2πr at the denominator, leaving us with just h  while on the left-hand side of the equation S-2πr² will be divided by 2πr)

S - 2πr²  /  2πr     =      h

Therefore the result should be h = S - 2πr²  /  2πr

Answer:

A) [tex]h =\frac{s}{2\pi r} -r[/tex]

Step-by-step explanation:

[tex]s = 2\pi rh + 2\pi r^2[/tex]

[tex]s = 2\pi r (h + r)\\h + r =\frac{s}{2\pi r} \\h =\frac{s}{2\pi r} -r[/tex]

Answer:

Step-by-step explanation:

as H=20 and W=10

So H=constant.(W)

H=2(10)

H=20

So constant is 2

The value of the constant in the equation that relates the height and width of the rectangle is 2

The given expression is:

H(w)  =  constant  x  w

where w represents the width

H represents the height

The point (w,  H) is given as (10, 20)

That is:

w  =  10,   H  = 20

Substitute w = 10 and H = 20 into the equation H(w) = constant x w

20   =   constant  x  10

constant =  20/10

constant  =  2

Therefore, the value of the constant in the equation that relates the height and width of the rectangle is 2

Solution:

The volume of a container varies jointly with the square of its radius, r, and its height, h

Therefore,

[tex]v \propto r^2h\\\\v = k \times r^2h ----------- eqn\ 1[/tex]

The  container has a height of 10 centimeters, and radius of 6 centimeters, and a volume of 377 cubic  centimeters

Substitute v = 377 and h = 10 and r = 6 in eqn 1

[tex]377 = k \times 6^2 \times 10\\\\377 = 360 \times k\\\\k = \frac{377}{360}\\\\k = 1.047 \approx 1.05[/tex]

What is the volume of a container with a radius of 4 centimeters and a height of 4  centimeters?

Substitute k = 1.05 and r = 4 and h = 4 in eqn 1

[tex]v = 1.05 \times 4^2 \times 4\\\\v = 1.05 \times 16 \times 4\\\\v = 67.2[/tex]

Thus volume of a container with a radius of 4 centimeters and a height of 4 centimeters is 67.2 cubic centimeter

The volume of the container with a radius of 4 cm and a height of 4 cm is 201.088 cm³.

To find the volume of a cylinder, we can use the formula:

V = πr²h

Given that the container has a height of 10 cm, a radius of 6 cm, and a volume of 377 cm³, we can substitute these values into the formula:

V = 3.142 × (6 cm)² × 10 cm

After evaluating the expression, we find that the volume of the container is 1130.152 cm³.

To find the volume of the container with a radius of 4 cm and a height of 4 cm, we can substitute these values into the formula:

V = 3.142 × (4 cm)² × 4 cm

After evaluating the expression, we find that the volume of the container is 201.088 cm³.
