The Formula A=23.1 E^{0.0152t} Models The Population Of A US State, A, In Millions, T Years After 2000.a.

Answers

Answer 1

We want to study the population formula of a given US state according to exponential equation.

a) 23.1 millions.

b) in 2013 - 2014

What is exponential equation?

The exponential function may be a function denoted by f(x)=\exp or e^. Unless otherwise fixed, the term usually refers to the positive-valued operate of a true variable

Main body:

The population state is:

A = 23.1*e^(0.0153*t)

In millions.

Where t represents the number of years after 2000.

a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).

A(0) = 23.1*e^(0.0153*0) = 23.1

The population at year 2000 was 23.1 millions.

b) Now we want to solve:

A(t) = 28.3 = 23.1*e^(0.0153*t)

        28.3/23.1 = e^(0.0153*t)

       1.23 = e^(0.0153*t)

Now we can apply the natural logarithm to both sides:

ln(1.23) = ln( e^(0.0153*t) )

ln(1.23) = 0.0153*t

ln(1.23)/0.0153 = t = 13.5

Hence, 13.5 years after 2000 the population will be 28.3 million.

The plane is perpendicular to the axis but does not go through the vertex. The plane intersects the double cone at only the vertex is ellipse.

How to identify the properties of an ellipse?

A planar curve that has two focal points is normally called an ellipse on the condition that at every point on the curve, it will be seen that the sum of the two distances from the focal points is constant. This generalizes the shape of a circle, which is a unique variety of an ellipse whereby the two focus points coincide.

The plane is said to not be intersecting with the vertex, not parallel to the axis nor perpendicular to the axis, then not parallel to the side of the cone, but it intersects only one cone is called a circle.

A circle is defined as a closed, two-dimensional object whereby every point in the plane is seen to be equally spaced from a central point. The line of reflection symmetry is seen to be formed by all lines that transverse the circle. Additionally, every angle has rotational symmetry around the center.

Thus, the conclusion is that the first two options are properties of an ellipse.

A solid object is made with the combination of a cylinder and a cone having same radii. The height of the cylinder and the slant height of the cone are 30 cm and 26 cm respectively. If the total cost of painting the total surface of the solid object at the rate of Rs 210 per 100 sq. cm is Rs 6336, find the height of the cone.

Answers

The total surface area of the solid object is the sum of the surface area of the cylinder and the surface area of the cone.

The surface area of the cylinder is 2πr(r+h), where r is the radius of the cylinder and h is its height.

The surface area of the cone is πr(l+r), where r is the radius of the cone and l is its slant height.

Since the cylinder and the cone have the same radius, we can call this radius r.

The total surface area of the solid object is therefore 2πr(r+h) + πr(l+r).

We are told that this total surface area is equal to 6336/210 = 30 sq. cm.

Thus, we can set up the equation: 2πr(r+h) + πr(l+r) = 30.

We are trying to find the value of l, which is the slant height of the cone. We are given the value of h, which is the height of the cylinder. We can substitute this value into the equation to get:

2πr(r+30) + πr(l+r) = 30.

This equation can be rearranged and solved for l to find the slant height of the cone.

l = sqrt(900 - 60r).

Since we are given that the slant height of the cone is 26 cm, we can substitute this value into the equation to solve for the radius of the cone:

26 = sqrt(900 - 60r)

Solving for r, we find that the radius of the cone is 15 cm.

Substituting this value back into the equation for the slant height of the cone, we find that the height of the cone is:

l = sqrt(900 - 60(15)) = sqrt(300) = 17.67 cm.

Thus, the height of the cone is approximately 17.67 cm.

Answers

The solution of linear equations in two variables gives the following results.

The number of long tables = 11The number of round tables = 9 What are linear equations in two variables?

A linear equation in two variables is one that is written in the form ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e. a and b, are not equal to zero.

Given:

Total number of tables in dining hall = 20 people

The number of people who can seat at long table = 10 people

The number of people who can seat at the round table = 10 people

According to the question, let’s assume a linear equation in two variables

number of long tables = x

number of round tables = y

⇒ x +y=20 ………… (1)

⇒10 x + 8 y=182 ………...(2)

Multiply equation (1) by 8 and subtract it from equation 2.

⇒ 10x+8y=182 ………… (2)

⇒ 8x+8 y=160 ………....(1)

⇒2x=22

⇒x=11

now put the value of x in equation (1) we get,

⇒11+y=20

⇒y=20-11

⇒y=9

Therefore, the number of long tables = 11

The number of round tables = 9

a) The null hypothesis is: [tex]H_0: p \leq 0[/tex]

b) The alternative hypothesis is: [tex]H_1: p > 0[/tex]

c) The test statistic is: z = 9.71.

d) The correct option is of: A. Yes.

e) The confidence interval is of: 0.0819 < p < 0.1336.

What are the hypothesis tested?


At the null hypothesis, it is tested if there is not enough evidence that the proportion for men is greater, that is, the subtraction is not greater than 0:

[tex]H_0: p \leq 0[/tex]

At the alternative hypothesis, it is tested if there is evidence that the proportion for men is greater, that is, if the subtraction is greater than 0, hence:

[tex]H_1: p > 0[/tex]

We have a right-tailed test, as we are testing if the mean is greater than a value, with a significance level of 0.01, hence the critical value is of:

z = 2.327.

Thus the decision rule regarding the test statistic is given as follows:

z < 2.327 -> not enough evidence of difference -> do not reject the null hypothesis.z > 2.327 -> enough evidence of difference ->  reject the null hypothesis.

What are the mean and the standard error of the distribution of differences?

For each sample, the mean and the standard error are given as follows:

Men: [tex]p_m = \frac{88}{800} = 0.11, s_m = \sqrt{\frac{0.11(0.89)}{800}} = 0.0111[/tex]Women: [tex]p_w = \frac{6}{2750} = 0.0022, s_w = \sqrt{\frac{0.0022(0.9978)}{2750}} = 0.0009[/tex]

Hence, for the distribution of differences, the mean and the standard error are given as follows:

Mean: p = 0.11 - 0.0022 = 0.1078.Standard error: s = sqrt(0.0111² + 0.0009²) = 0.0111.

What are the test statistic and the conclusion:

The test statistic is given by the division of the mean by the standard error of the sampling distribution of the difference of sample proportions, hence:

z = 0.1078/0.0111 = 9.71.

z > 2.327 -> enough evidence that the proportion is greater.

What is the confidence interval?

The confidence interval is obtained as the mean plus/minus the multiplication of the standard error and of the critical value.

Then the bounds of the interval are:

Lower bound: 0.1078 - 2.327 x 0.0111 = 0.0819.Upper bound: 0.1078 + 2.327 x 0.0111 = 0.1336.

Step-by-step explanation:

Vertical Angles Theorem

When two straight lines intersect, the opposite vertical angles are congruent.

Linear Pair

Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

Corresponding Angles Postulate

When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.

Given:

m∠9 = 110°m∠8 = 70°p || q

Apply the Vertical Angle Theorem to find the measure of angle 8:

⇒  m∠3 = m∠8 = 70°

As angles 7 and 8 form a linear pair:

⇒  m∠7 + m∠8 = 180°

⇒  m∠7 + 70° = 180°

⇒  m∠7 = 110°

As line p is parallel to line q, apply the Corresponding Angles Postulate to find the measure of angle 15:

⇒  m∠15 = m∠7 = 110°

Therefore, the measure of angle 15 is 110°.

A linear function h models a relashinship in which the dependent variable decreases 2 units for every 5 units the independent variable increase. Graph h when h(0)=4

Answers

By using slope intercept form of equation of line, the graph of

h(x) = [tex]-\frac{2}{5}x + 4[/tex] has been shown

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Let the independent variable be x and dependent variable be h(x)

The dependent variable decreases 2 units for every 5 units the independent variable increase.

Slope = [tex]-\frac{2}{5}[/tex]

So,

h(x) = [tex]-\frac{2}{5}x + c[/tex]

Now,

h(0) = 4

So, c = 4

h(x) = [tex]-\frac{2}{5}x + 4[/tex]

Δ PQR, P=(4 x+11)°, m∠Q=(2 x+1)°, and m∠R=(7 x-14)°. Find m∠P.

Answers

Answer:

67°

Step-by-step explanation:

Th sum of the interior angles of a triangle is 180.  Set the measurements of the three sides to 180 and solve for x.  Then substitute in the value for x in 4x  +11

4x + 11 + 2x + 1 + 7x -14 = 180  Combine like terms

13x - 2 = 180  Add 2 to both sides

13x = 182  Divide both sides by 13

x = 14

Plug this in for x

4x + 11

4(14) + 11

56 + 11

If a sample of a certain solution is determined to have a [H3O+] concentration of 8.25×10−3 moles/liter, what is its pH?

Answers

where log is the base-10 logarithm and [H+] stands for the hydrogen ion concentration in units of moles per liter solution.

What is this pH?The pH of water determines how acidic or basic it is. The scale runs from 0 to 14, with 7 being neutral. pHs less than 7 indicate acidity, while pHs greater than 7 indicate base. pH is a measure of the relative amount of free hydrogen and hydroxyl ions in water.Hawkes Learning says the answer is 0.0. I tried this problem and got it wrong at first, but they said the correct answer is 0.0.Before attempting to answer this question, it may be useful to review the properties of logarithms and the definition of pH.The pH of a solution is a measure of the concentration of hydrogen ions, as well as its acidity or alkalinity. The pH scale is normally between 0 and 14. Aqueous solutions with a pH less than 7 at 25 ° C are acidic, while basic or alkaline solutions have a pH greater than 7.

pH=−log([H3O+])

=−log(8.25×10−3)

=−log(8.25)−log(10−3) loga(xy)=loga(x)+loga(y)

=−log(8.25)+1 log(10x)=x

=0.0 round off to one decimal place

pH is defined as the negative logarithm of hydrogen ion concentration present in a solution.To calculate the pH of the reaction, we use the equation:[tex]pH = -log[H^{+} ][/tex]

where,

Putting values in above equation, we get:Hence, the pH of the solution is 1.022
