what is the circumference of a circle p PB=29m

To determine which is larger between  k(8) - k(7)  and  k(3) - k(2) , compare the specific values. If the graph of  k(t)  is concave upward, studying more hours yields a larger knowledge increase.

To determine which is larger between  k(8) - k(7)  and  k(3) - k(2) , and to understand the concavity of the graph of  k(t) , consider the following:

1. Larger Increase in Knowledge:

  - Evaluate  k(8) - k(7)  and  k(3) - k(2) .

  - If  k(8) - k(7)  is greater, it implies that studying for an additional hour (from 7 to 8 hours) provides a larger increase in knowledge than studying for an hour from 2 to 3 hours.

2. Concavity of the Graph:

  - If  k''(t) > 0  (second derivative is positive), the graph is concave upward.

  - If  k''(t) < 0  (second derivative is negative), the graph is concave downward.

3. Reasoning for Concavity:

  - If the graph is concave upward, it suggests that the rate of knowledge gain is increasing. Studying more hours leads to a larger increase in knowledge.

4. Final Answer:

  - The comparison between  k(8) - k(7)  and  k(3) - k(2)  depends on the specific function  k(t) . As for concavity, if the graph is concave upward, studying more hours yields a larger increase in knowledge.

In summary, compare the specific values  k(8) - k(7)  and  k(3) - k(2)  and analyze the concavity of the graph to determine the relationship between studying hours and knowledge gain.

Question. Let k(t) be a measure of the knowledge you gain by studying for a test for t hours, . Which do u think is larger, k(8)-k(7) or k(3) - k(2) ? is the graph of k concave upward or concave downward? why?

Final answer:

The slope of the equation y = 1/4x + 3 is 1/4 and the y-intercept is 3, corresponding to option A: slope: 1/4 ; y-intercept: 3.

Explanation:

To identify the slope and y-intercept of the equation y = 1/4x + 3, we can compare it to the general form of the slope-intercept equation for a line, which is y = mx + b. In this form, m represents the slope of the line, and b represents the y-intercept of the line. Thus, looking at the given equation, the coefficient of x (which is 1/4) is the slope, and the constant term (which is 3) is the y-intercept.

The correct answer is:

Therefore, the answer is option A: slope: 1/4 ; y-intercept: 3

Answer:

A- The distance that represents 11 billion years is 244.4 meters.

B- Written human history begins 0.2 milimeters far from the end of the timeline.

Step-by-step explanation:

A- We can solve this problem by using crossed multiplication.

4,5 billion years --- 100 meters

11 billion years --- X

11 x 100 / 4,5 = X

X= 244.4

B- Once again, this can be solved using crossed multiplication.

If 4,500,000,000 years are represented in 100 meters, that would be:

4,500,000,000 --- 100 meters

10,000 --- X

10,000 x 100 / 4,500,000,000 = X

X= 0.0002 meters

0.0002 meters are 0.2 milimeters

The vector v = (4, -1) can be written as a linear combination of the vectors u = (2, 2) and w = (2, -3). The coefficients are both 1, which means that v = u + w.

In this problem, we are trying to express the vector v = (4, -1) as a linear combination of the vectors u = (2, 2) and w = (2, -3). A linear combination means that we want to find coefficients a and b such that a*u + b*w = v.

Setting that equation up, we have:
a(2, 2) + b(2, -3) = (4, -1).
This leads to two equations:
2a + 2b = 4 and 2a - 3b = -1.

After solving this system of equations, we find that a = 1 and b = 1. Therefore, the vector v can be written as a linear combination of u and w as v = u + w.

V can be written as v=u+w.

To express v as a linear combination of u and w, we need to find scalars a and b such that:

v = a * u + b * w

Given: u = (2, 2), w = (2, -3), and v = (4, -1)

We can set up the following system of equations based on the components:

2a + 2b = 4 (Equation 1 from x-components)

2a - 3b = -1 (Equation 2 from y-components)

Solving Equation 1 for 'a':

2a + 2b = 4

a + b = 2

a = 2 - b

Substituting 'a' in Equation 2:

2(2 - b) - 3b = -1

4 - 2b - 3b = -1

4 - 5b = -1

-5b = -5

b = 1

Substituting 'b' back into a = 2 - b:

a = 2 - 1

a = 1

Thus, v can be written as:

v = 1 * u + 1 * w

So, v = u + w

Answer:

68 divide by 4

Step-by-step explanation:

The slope of a line that is parallel to the line shown on the graph is -3.

The slope or gradient of a line is a number that describes both the direction X and Y and the steepness of the line. It is the ratio of the vertical change to the horizontal change between any two distinct points on a line.

For the given situation,

The slope of a line from its graph by looking at the rise and run.

The vertical change between two points is called the rise, and the horizontal change is called the run.

One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

Now take points (0,2) and (1,-1)

[tex]Slope = \frac{rise}{run}[/tex]

Line slants down from left to right. So line has a negative slope.

⇒ [tex]Slope =\frac{y2-y1}{x2-x1}[/tex]

⇒ [tex]Slope =\frac{-1-2}{1-0}[/tex]

⇒ [tex]Slope = -3[/tex]  

The slope of the line that is parallel to the given line is same as that of the line.

Hence we can conclude that the slope of a line that is parallel to the line shown on the graph is -3.

Answer:

Apex answer: FALSE

Step-by-step explanation:

Final answer:

The consumer price index decreasing from 200 to 150 represents a 25% decrease, not 50% as incorrectly stated.

Explanation:

The statement that prices decrease by 50% when the consumer price index (CPI) decreases from 200 to 150 is false. To calculate the percentage decrease in CPI, we use the formula for percentage change: ((new value - original value) / original value) × 100. In this case, ((150 - 200) / 200) × 100 = (-50 / 200) × 100 = -25%. This shows that there is a 25% decrease in the CPI, not 50%.

The correct calculation reveals that the decrease in the Consumer Price Index (CPI) is 25%, not 50%.

Understanding the accurate interpretation of percentage changes is crucial for assessing economic indicators and making informed decisions.

also total nuts must be equal to 6

i.e. [tex]\dfrac{3}{4}x=6[/tex]

Multiplying both sides by 4, we get

3x=24

Dividing both sides by 3, we get

x=8

Hence, number of bags Miranda makes equals:

To divide fractions, multiply the first fraction by the reciprocal of the second fraction and simplify if possible.

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is found by switching the numerator and denominator. So, to divide 5/18 by 2/6, we will multiply 5/18 by 6/2.

First, we cancel out any common factors between the numerators and denominators:

5/18 * 6/2 = (5 * 6)/(18 * 2) = 30/36.

Now, we can simplify 30/36 by finding the greatest common divisor (GCD) of 30 and 36, which is 6.

Dividing both the numerator and denominator of 30/36 by 6, we get the final quotient of 5/6.

Answer:  The correct option is

(A) m = 1; (0, 3).

Step-by-step explanation:  We are given to find the slope, m, and the y-intercept of the graphed line.

We know that

the slope of a line passing through the points (a, b) and (c, d) is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

From the graph, we note that the line passes through the points (-3, 0) and (-1, 2).

Therefore, the slope of the graphed line will be

[tex]m=\dfrac{2-0}{-1-(3)}=\dfrac{2}{2}=1.[/tex]

Also, at x = 0, the value of the y-coordinate is 3. So, the y-intercept of the line is (0, 3).

Thus, the slope, m = 1  and the y-intercept is (0, 3).

Option (A) is CORRECT.

Final answer:

To solve for g in the equation 4gh+3=-8 with H=-1, we substitute H and solve for g, resulting in g=11/4.

Explanation:

The question asks to solve for g in the equation 4gh + 3 = -8. To do this, we need to isolate g on one side of the equation. Given that H = -1, we can substitute this value into the equation, which simplifies to 4g(-1) + 3 = -8. This further simplifies to -4g + 3 = -8. Solving for g, we subtract 3 from both sides to get -4g = -11, and then divide both sides by -4 to get g = 11/4. Therefore, the solution is g = 11/4.

The container cannot hold a specific number of gallons.

To solve this problem, we can use a proportion. Let's assume that the number of gallons the container can hold is According to the problem, the container is initially 1/3 full, so we can write this as 1/3 of  After pouring out 6 gallons of water, it becomes 1/9 full, which we can write as 1/9 of  Setting up the proportion, we have:

1/3 of  = 1/9 of

To solve for  we can cross multiply:

9 * (1/3) *  = 1 * (1/9) *

Canceling out the variables and multiplying, we have:

3= /9

Multiplying both sides by 9, we get:

27=

Dividing both sides by , we have:

27 = 1

Since the equation is not true, we have a contradiction. This means there is no solution, or the container cannot hold a specific number of gallons.

Final answer:

The total capacity of the football team's water container is 27 gallons. We determine this by comparing the change in water level from being 1/3 full to 1/9 full after removing 6 gallons and calculating proportionally.

Explanation:

To solve the problem regarding the water container for the football team, we need to find out the total capacity of the container. When 6 gallons of water is poured out, it results in the container being 1/9 full rather than 1/3, which means the removal of 6 gallons of water equates to 1/3 - 1/9 of the container's capacity.

First, let's find the common denominator for 1/3 and 1/9 which is 9. So the difference in the water level when the 6 gallons were removed is (3/9 - 1/9) or 2/9 of the container's capacity. This tells us that 2/9 of the container's capacity is equal to 6 gallons.

Step-by-Step Calculation

Set up the proportion: 2/9 = 6 gallons.

To find the full capacity, we solve for 9/9 (which is the whole): (9/9) / (2/9) = X / 6 gallons.

Cross multiply to solve for X: 2X = 54.

Divide both sides by 2: X = 27.

Therefore, the total capacity of the water container is 27 gallons.

Answer:

The correct option is B.

Step-by-step explanation:

In table A, the function has constant rate of change. For each value of x, the value of y increased by 8.

Since the rate of change of a linear function is constant, therefore table A represents a linear function.

In table B, for each value of x, the value of y is twice of its previous value. In other words we can say that the value of y increases in the same proportion.

[tex]\frac{y_2}{y_1}=\frac{8}{2}=2[/tex]

[tex]\frac{y_3}{y_2}=\frac{16}{8}=2[/tex]

[tex]\frac{y_4}{y_3}=\frac{32}{16}=2[/tex]

[tex]\frac{y_5}{y_4}=\frac{64}{32}=2[/tex]

Therefore it is an exponential function with growth factor 2.

The function passing through the point (1,4).

[tex]4=a(2)^1[/tex]

[tex]2=a[/tex]

The exponential function is

[tex]f(x)=2(2)^x[/tex]

Thus, option B is correct.

In table C, the function has constant rate of change. For each value of x, the value of y increased by 5.

Since the rate of change of a linear function is constant, therefore table C represents a linear function.

In table D, the function has constant rate of change. For each value of x, the value of y increased by 1.

Since the rate of change of a linear function is constant, therefore table D represents a linear function.
