a) To estimate the answer for 763 x 42 / 82, we round each number to 1 significant place: The estimated answer for 39 x 52 / 3.8 x 4.9 is 50.

763 becomes 800 (rounding to the nearest hundred)

42 becomes 40 (rounding to the nearest ten)

82 becomes 80 (rounding to the nearest ten)

Now we can calculate the estimated answer: 800 x 40 / 80 = 400.

So, the estimated answer for 763 x 42 / 82 is 400.

b) To estimate the answer for 39 x 52 / 3.8 x 4.9, we round each number to 1 significant place:

39 becomes 40 (rounding to the nearest ten)

52 becomes 50 (rounding to the nearest ten)

3.8 becomes 4 (rounding to the nearest whole number)

4.9 becomes 5 (rounding to the nearest whole number)

Now we can calculate the estimated answer: 40 x 50 / 4 x 5 = 1000 / 20 = 50.

So, the estimated answer for 39 x 52 / 3.8 x 4.9 is 50.

Answer:

k = -11

Step-by-step explanation:

Let \(p(x) = x^3-6x^2+kx+10\)

And x+2 is a factor of p(x)

Let x+2 = 0 => x = -2

Putting in p(x)

=> p(-2) = \((-2)^3-6(-2)^2+k(-2)+10\)

By remainder theorem, Remainder will be zero

=> 0 = -8-6(4)-2k+10

=> 0 = -8-24+10-2k

=> 0 = -22-2k

=> -2k = 22

Dividing both sides by -2

=> k = -11

Answer: |t - 15| ≤ 30 ; -30 ≤ t - 15 ≤ 30

Step-by-step explanation:

To set up the equation, we have to find the center, and the tolerance, so that we can use formula "|x - c| ≤ t"

First, we can find the tolerance by adding both number, then dividing by 2 --> -15 + 45 = 30 --> 30/2 = 15, so we now know that the center is 15

Next, we can find the tolerance by finding the distance between the center and one of the number --> 15 - (-15) = 30, so we now know that the tolerance is 30

Now we can set up our equation,

center (c) = 15

tolerance (t) = 30

|t - 15| ≤ 30

Now that we have our equation, we can set up the inequality

|x - c| ≤ t = -t ≤ x - c ≤ t

so,

-30 ≤ t - 15 ≤ 30

Hope this helps!

No they are not equivalent and no, the ratios do not simplify to the same fraction.

What is Ratio?

A ratio displays the multiplicity of two numbers. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

Concept:

If two or more ratios have the same simplified forms, they are equal. Therefore, we must multiply the two amounts by the same number in order to discover a ratio that is equivalent to another.

The provided ratio can also be expressed as a fraction, and the numerator and denominator can then be multiplied by the same amount to get equal fractions. Alternatively, the resulting fraction can be expressed as an equivalent ratio.

Additionally, we can obtain the simplest form of a ratio by dividing two numbers by their highest common factor when comparing any two equivalent ratios. We can thus compare them.

These are some instances of equivalent ratios:

2 : 4 :: 4 : 8

10 : 20 :: 20 :40

1 : 2 :: 2 : 4

0.5 : 1 :: 2:4

The formula for the circumference of a circle is "c = 2 pi r", where "c" represents the circumference, "pi" represents the mathematical constant pi (approximately equal to 3.14159), and "r" represents the radius of the circle.

This formula relates the distance around a circle to its size, and is useful for calculating various measurements related to circles, such as arc length and sector area. It is important to note that the formula for the circumference of a circle assumes the circle is a perfect, unbroken curve, and thus may not be accurate for circles that are not perfectly round.

The value of  fog= gof is x² - 5x = 0

Functions are rules or expressions showing the relationship between an independent and dependent variable.

Given the functions:

fog(x) and gof(x) are both known as composite functions

If fog(x) = gof(x)

Then , we have

\(\frac{x - 2}{x -2 + 3} = \frac{x}{x + 3} -2\)

solve the fractions

\(\frac{x-2}{x -1} = \frac{2x - 2x +6}{x+3}\)

\(\frac{x -2}{x -1} = \frac{6}{x + 3}\)

cross multiply

(x -2) ( x+ 3) = 6 ( x -1)

expand the bracket

x²+ 3x - 2x - 6 = 6x - 6

collect like terms

x² - 5x + 0 = 0

x² - 5x = 0

Thus, the value of  fog= gof is x² - 5x = 0

The most likely mean for the sample distribution is option c. negatively skewed.

Based on the given information, we know that the mean (M) is less than both the median and the mode. This suggests that the distribution is skewed to the left (negatively skewed), with a long tail on the left side of the distribution.

The mean of a sample distribution is the average value of all the observations or measurements in the sample. It is calculated by adding up all the values in the sample and dividing the sum by the total number of observations in the sample.

After 412 years there will be no trees at the state park.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

From the given information,

Slope(m) = (42 - 48)/(5 - 0).

Slope(m) = - 6/5.

b = 48,                                       As y-intercept(0, 48).

Therefore, y = - (6/5)x + 48.

Now, y = - (6/5)×412 + 48.

y = - 446.4 trees per acre, But there will be no trees as it came out to be a negative value.

The line segment in question, denoted as "c," connects the points (0, 0, 0) and (2, 4, 3) in three-dimensional space.

In three-dimensional Cartesian coordinates, a line segment can be defined by its two endpoints. The given line segment "c" connects the point (0, 0, 0) in space to the point (2, 4, 3). These coordinates represent the x, y, and z values, respectively, of each point.

To understand the line segment visually, we can consider a three-dimensional coordinate system. The point (0, 0, 0) represents the origin, located at the intersection of the x, y, and z axes. The point (2, 4, 3) is positioned at x = 2, y = 4, and z = 3, in relation to the origin.

The line segment "c" can be visualized as a straight line connecting these two points. It extends from the origin in the direction of (2, 4, 3), forming a line with a slope determined by the difference in coordinates between the two endpoints. In this case, the slope would be (2/2, 4/4, 3/3), simplifying to (1, 1, 1).
