Final answer:

To evaluate a logarithm, use the calculator's log button for the common logarithm or calculate 10 raised to the power of the logarithmic value for the inverse log. Logarithmic properties simplify expressions by converting multiplication into addition and exponents into multiplication.

Explanation:

Understanding and Evaluating Logarithms

To evaluate a logarithm, one can use a calculator's log button to find the common logarithm, which is based on base 10. If you have a logarithm and wish to find the actual number it represents, you take the inverse log of the logarithm. This can also be expressed as 10 to the power of the logarithmic value.

For instance, to evaluate log(100), you would press the log button on your calculator and then enter 100. The result would be 2, since 10^2 = 100. If you have the logarithm value, say 3, and want to find the number it corresponds to, calculate 10^3, which equals 1000.

Furthermore, logarithmic properties can be used to simplify expressions and solve equations. If you take the log of two numbers being multiplied, you can add their individual logs. Additionally, taking the log of a number raised to an exponent allows you to move the exponent in front of the log, thus multiplying the exponent by the log of the number.

During the seventeenth century, the principle of the logarithm was developed by Napier. Logarithms transform multiplication into addition, which simplifies many computations, like using antilogarithms and slide rules for multiplication.

Answer:

56,000.0

Step-by-step explanation:

The number 6 is in the nearest thousand. To round, you look at the number in front of the number you are trying to round and decide if that number is higher or lower than five. If the number is higher than 5, round up to the next highest number. If the number is lower than 5, the number stays the same.

Final answer:

To round 56,291.8 to the nearest thousand, observe the hundreds digit; it's 2, less than 5, so we keep 56,000 and replace subsequent digits with zeros, giving a rounded figure of 56,000.

Explanation:

To round 56,291.8 to the nearest thousand, we need to look at the hundreds place, which is 2 in this case. Since this is less than 5, we don't round up the thousands place. Therefore, we keep the number 56,000 as it is without increasing the thousand's value. However, since we are rounding to the nearest thousand, we replace the hundreds, tens, ones, and decimal places with zeros, resulting in the final rounded number being 56,000.

Answer:

y = -x + 5

y - 0 = - (x - 8)

y = -x + 8

Step-by-step explanation:

The required equation of the line is y = 8 - x.

Given that,
To determine an equation of the line that passes through the point (8,0) and is parallel to the line x+y=5

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
Given equation,

x+y=5
y = -x + 5
m = -1
Since the slope of parallel lines are equals.
So the equation of the line is given as, which is passing by (8,0)
y - 0 = -1 (x - 8)
y = 8 - x

Thus, the required equation of the line is y = 8 - x.

Step-by-step explanation:

answer D would also be true

Answer: Her solution is incorrect. The hypotenuse is 53 units

Step-by-step explanation: The error occurred when she quoted the Pythagorean theorem. She added up both sides and squared them and made the answer equal to the square of the hypotenuse. She was supposed to have squared them first, before adding up.

The Pythagorean (or Pythagoras) theorem states that the sum of the squares of two sides of a right angled triangle equals the square of the hypotenuse of the triangle. That is, in triangle ABC, if the hypotenuse is given as line AC, the Pythagoras theorem states that

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse and AB and BC are the other two sides.

In Nadia’s solution, if the hypotenuse is given as 73, and the other two sides are 28 and 45, then the Pythagorean theorem properly expressed would be as follows;

73^2 = 28^2 + 45^2

5329 = 784 + 2025

5329 ≠ 2809

As we have determined, writing out the expression as

73^2 = (28 + 45)^2 is very incorrect as this is not the Pythagorean theorem and of course, the triangle cannot have 73 as its hypotenuse as we have determined by properly writing out the Pythagorean theorem.

The correct solution is as follows;

AC^2 = AB^2 + BC^2

AC^2 = 28^2 + 45^2

AC^2 = 784 + 2025

AC^2 = 2809

Add the square root sign to both sides of the equation

AC = 53

Therefore, the hypotenuse is 53 units

For the prime numbers it's 15/50 or 3/10. For it to be at least 20 it's 31/50. For both to happen at the same time it's 7/15.

Step-by-step explanation:

The prime numbers between 1 and 50 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47.

50-19=31 so 31/50

The probability of drawing a prime number that is at least 20 from a bucket of 50 numbers is 0.2, or 20%.

In this problem, you are being asked to find the probability that a number selected at random from a pool of 50, numbered 1 to 50, is both at least 20 and a prime number. In this case, let's first consider the prime numbers between 1 and 50, of which there are 15 (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47). However, we are looking for prime numbers that are also at least 20. This leaves us with 10 prime numbers (23, 29, 31, 37, 41, 43, 47).

With these 10 prime numbers, and 50 total numbers to choose from, the probability can thus be calculated by dividing the number of successful outcomes by the total number of outcomes. Therefore, the probability P(at least 20 | prime number) is 10/50 or 0.2. This means there is a 20% chance of randomly drawing a number from the bucket that is least 20 and also a prime number.

The length of rectangle is 105 cm and width is 98 cm.

Step-by-step explanation:

Given,

Perimeter of rectangle = 406 cm

Let,

w be the width of rectangle

Length of rectangle = w+7

We know that

Perimeter of rectangle = 2(Length + Width)

[tex]406 = 2(w+7+w)\\406 = 2(2w+7)\\406 = 4w+14\\406-14 = 4w\\392=4w\\4w=392[/tex]

Dividing both sides by 4

[tex]\frac{4w}{4}=\frac{392}{4}\\w=98[/tex]

Width of rectangle = 98 cm

Length of rectangle = 98+7 = 105 cm

The length of rectangle is 105 cm and width is 98 cm.

Bo teaches 16 classes per week and Erica teaches 20 classes per week.

To find out how many yoga classes Bo and Erica each teach per week, we can set up a system of equations based on the given information.

Let B represent the number of classes Bo teaches per week. Let E represent the number of classes Erica teaches per week.

According to the problem, the total number of classes taught by Bo and Erica is 36:

Equation 1: B + E = 36

Also, we know that Erica teaches 12 fewer than twice as many classes as Bo:

Equation 2: E = 2B - 12

We can substitute the expression for E from Equation 2 into Equation 1:

B + (2B - 12) = 36

Simplify and solve for B:

So, Bo teaches 16 classes per week. Now we can find out how many classes Erica teaches by substituting B back into Equation 2:

E = 2(16) - 12

E = 32 - 12

E = 20

Therefore, Erica teaches 20 classes per week.

Thus, Bo teaches 16 classes per week and Erica teaches 20 classes per week.

To find the equation of the line passing through two given points, we can use the slope-intercept form of a line. The equation of the line passing through (-5,2) and (9,0) is y = -1/7x + 9/7.

Explanation:

To find the equation of the line that passes through the points (-5,2) and (9,0), we can use the slope-intercept form of a line, y = mx + b. First, we need to find the slope (m) of the line. The slope is given by the formula m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Plugging in the values, m = (0 - 2)/(9 - (-5)) = -2/14 = -1/7.

Next, we can choose one of the points and plug in its coordinates along with the slope into the equation y = mx + b to solve for b. Let's choose the point (-5,2): 2 = (-1/7)(-5) + b. Simplifying the equation, 2 = 5/7 + b. Subtracting 5/7 from both sides, 2 - 5/7 = b. Getting a common denominator, 14/7 - 5/7 = b. So, b = 9/7.

Finally, we can substitute the values of m and b into the equation y = mx + b to get the equation of the line: y = -1/7x + 9/7.
