What is the logarithm?

A logarithm is a power to which a number must be raised in order to get some other number. For example, the base ten logarithms of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because. 102 = 100.

The change of base formula for logarithms allows us to change the base of a logarithm without changing the value of the logarithm.

The formula is: logb(x) = (logc(x)) / (logc(b))

To solve 5x - 2 = 8 using the change of base formula, we will first bring the equation to one side and get 2 = 5x - 8.

Then we will add 8 to both sides of the equation to get 2 + 8 = 5x, which gives us 10 = 5x.

Finally, we will divide both sides of the equation by 5 to get x = 2.

x = 2

Therefore, x = 2 is the solution to the equation 5x - 2 = 8.

Answers

Heritability is typically divided into two categories, namely broad sense and narrow sense heritability.

The following formulas are used to calculate heritability in the broad sense:

H² = Vg / Vp

Where,

H² = Heredity

Vg = Genotypic Variance

Vp = Phenotypic Variance

FOR BACK FAT:

Vg = 13.7

Vp = 28.9

H² = Vg / Vp

H² = 13.7 / 28.9

H² = 0.474

FOR BODY LENGTH:

Vg = 27.2

Vp = 49.1

H² = Vg / Vp

H² = 27.2 / 49.1

H² = 0.553

These formulas are used to calculate narrow sense heredity:

H² = Vg / Vp

Where,

H² = Heredity

Vg = Genotypic Variance

Va = Additive Genetic Difference

FOR BACK FAT:

Vp = 28.9

Va = 7.98

H² = Va / Vp

H² = 7.98 / 28.9

H² = 0.276

FOR BODY LENGTH:

Vp = 49.1

Va = 12.4

H² = Va / Vp

H² = 12.4 / 49.1

H² = 0.252

Because back fat has a high narrow sense of heredity and a low broad sense of heritability, it is the best pick. Additionally, heritability in the restricted sense has good breeding value.

If the dimensions of the box were all doubled, then the surface area of the box be 640 square units.

Use the concept of prism defined as:

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat sides, and identical bases.

Without bases, the prism's faces are parallelograms or rectangles. And any n-sided polygon, whether a triangle, square, rectangle, or other, might serve as the prism's basis.

Given that,

The dimension of the rectangular prism = 2yd x 10yd x 5yd

Since we know that,

Dimension of prism = length x breadth x height

length x breadth x height =  2yd x 10yd x 5yd

Therefore,

Length = 2 yd

Breadth = 10 yd

Height = 5 yd

Now if dimension doubled the,

The dimension of the new prism = 4yd x 20yd x 10yd

Then,

Length 'l' = 4 yd

Breadth 'b'= 20 yd

Height 'h' = 10 yd

Since we know that,

The surface area of a rectangular prism is,

A=2(bl+hl+hb)

seconds.
(a) The maximum speed of the object on the time interval is at time .
(b) The minimum speed of the object on the time interval is at time .

Answers

In the given time interval [0,7]:

(a) the maximum speed is 1096.63 units at t = 7 and

(b) the minimum speed is 0.91 units at time t = ln2/4.

Parametric equations of the curve

x(t) = [tex]e^t + e^{-t}[/tex]

y(t) = [tex]e^{-t}[/tex]

so, dx/dt = [tex]e^t - e^{-t}[/tex]

dy/dt = [tex]-e^{-t}[/tex]

So, speed: v(t) = [tex]\sqrt{(dx/dt)^2 + (dy/dt)^2}[/tex] = [tex]\sqrt{(e^t-e^{-t})^2 + (-e^{-t})^2}[/tex]

When v(t) is maximized or minimized, evidently v² is also maximized or minimized because speed is a positive quantity.

or (speed)² = v² = [tex](e^t-e^{-t})^2 + (-e^{-t})^2[/tex] = [tex](e^{2t} + 2e^{-2t} -2)[/tex]

Now, to get the maxima or minima of a curve we have to derivate function

d/dt(v²) = 0 or d/dt[tex](e^{2t} + 2 e^{-2t} -2)[/tex]

or [tex]2e^{2t} -4 e^{-2t} = 0[/tex] or [tex]e^{2t} = 2 e^{-2t}[/tex]

taking logs on both sides

4t lne = ln2 or 4t = ln2 or t = ln2/4

so, the only critical point is t = ln2/4 ∈ [0,7]

To calculate the maxima/minima of v, we will find functional values at the critical point and boundary values of the given interval [0,7].

At t = 0 : v(0) = [tex]\sqrt{e^0 + 2e^0 - 2} = \sqrt{1+2-2}[/tex] = 1

At t = ln2/4: v(ln2/4) = [tex]\sqrt{e^{2ln2/4} + 2e^{-2ln2/4} - 2} = \sqrt{2\sqrt{2} -2 }[/tex] = 0.91

At t = 7: v(7) = [tex]\sqrt{e^{14} + 2e^{-14} - 2}[/tex] = 1096.63

Therefore, in the given time interval [0,7]: (a) the maximum speed is 1096.63 units at t = 7 and (b) the minimum speed is 0.91 units at time t = ln2/4.

Answers

The time estimates for units 2, 3, 4, and 5, rounded to 2 decimal places, are 4.8 hours, 34.56 minutes, 4.14 minutes, and 0.48 minutes respectively.

A learning percentage is the percentage by which the time required to complete a task decreases as the number of units produced increases. In this case, the learning percentage is 88%.

To develop the time estimates for units 2, 3, 4, and 5, we can use the formula:

Time for unit n = Time for unit 1 (1 - learning percentage)⁽ⁿ⁻¹⁾

Where n is the unit number, and the learning percentage is expressed as a decimal.

For example, to find the time estimate for unit 2:

Time for unit 2 = Time for unit 1 (1 - 0.88)⁽²⁻¹⁾

= 40 (1 - 0.88)

= 40 × 0.12 = 4.8 hours

To find the time estimate for unit 3:

Time for unit 3 = Time for unit 1 (1 - 0.88)²

= 40 (1 - 0.88)²

= 40 × 0.12²

= 0.576 hours

= 34.56 minutes

To find the time estimate for unit 4:

Time for unit 4 = Time for unit 1 * (1 - 0.88)^(4-1)

= 40 * (1 - 0.88)^3

= 40 * 0.12^3

= 0.069 hours

= 4.14 minutes

To find the time estimate for unit 5:

Time for unit 5 = Time for unit 1 * (1 - 0.88)^(5-1)

what is hyperbola?

A hyperbola is a geometric shape made up of two branches that are symmetric about a center point and asymptotic to two lines called the asymptotes. It is defined by the equation (x^2/a^2) - (y^2/b^2) = 1. It is a type of conic section, similar to a parabola and an ellipse.

If the vertices and foci's of hyperbola have specified coordinates are of the form (0,10) and (0,14)

then

The y-axis serves as the transverse axis.

so

The formula for the equation is:

(y-k)^2/a^2-(x-h)^2/b^2=1

In this issue

The value of the center (h,k) is (0,4)

It follows that (0,a-k)) = (0,10)

a=10-4=6

(0,c-k) equals (0,14)

c=14-4=10

Identify b's value.

b^2=c^2-a^2

b^2=10^2-6^2

b^2=64

therefore

The formula reads as follows:

[tex]\frac{(y-4)^2}{36} + \frac{x^2}{64}[/tex] =1

suppose that 70% of college women have been on a diet within the past 12 months. a sample survey interviews an srs of 267 college women. what is the probability that 75% or more of the women in the sample have been on a diet?

Answers

The probability that 75% or more of the women in the sample have been on a diet is 0.944.

The probability that 75% or more of the women in the sample have been on a diet can be calculated by using the binomial formula. The formula is P(X>=x) = 1 - P(X<x). The parameters in this case are as follows: n = 267, p = 0.7, and x = 201.5 (which is 75% of 267). Therefore, the probability that 75% or more of the women in the sample have been on a diet is 1 - P(X<201.5). Solving for this probability, P(X>=201.5) is 0.944. Therefore, the probability that 75% or more of the women in the sample have been on a diet is 0.944.

A pole is being decorated with 13-meter ribbons that are strung from the top of the 6-meter pole to a point on the ground. Which is the measure of the angle formed by the ribbon and the pole? a. 24.8 b. 65.2 c. 27.5 d. 62.5

Answers

the tangent of the angle, which we can then use to calculate the angle in degrees. Therefore, angle = tan-1(6/13) = 65.2 degrees.

b. 65.2

To find the measure of the angle, we need to use the inverse tangent (tan-1) function.

angle = tan-1(6/13)

angle = 65.2

We need to use the inverse tangent (tan-1) function to calculate the measure of the angle. To do this, we need to divide the height of the pole (6 meters) by the length of the ribbon (13 meters). This will give us the tangent of the angle, which we can then use to calculate the angle in degrees. Therefore, angle = tan-1(6/13) = 65.2 degrees.

a test has 75 questions worth 216 points total. the test consists of multiple-choice questions worth 2 points each and short answer questions worth 4 points each. how many of the total points on the test are from short-answer questions? do your figuring here.

Answers

There are 33 short-answer questions on the test and 33 * 4 = 132 points are from short-answer questions.

What is algebra ?

Algebra is a branch of mathematics in which letters and symbols are used to represent numbers and quantities in equations and formulas. Algebraic concepts include operations such as addition, subtraction, multiplication, and division.

We know that the test has 75 questions and it is worth 216 points total.

We know that multiple-choice questions worth 2 points each and short answer questions worth 4 points each.

To calculate the number of points from short-answer questions, we need to find out how many questions are short-answer and multiply that by 4 (points per question).

Let x be the number of short-answer questions.

We know that x + 75 - x = 75, which is the total number of questions on the test.

Also, we know that x * 4 + (75-x) * 2 = 216, which is the total number of points on the test.

Solving for x, we get:

x * 4 + 150 - 2x = 216

2x = 66

x = 33

So there are 33 short-answer questions on the test and 33 * 4 = 132 points are from short-answer questions.
