What is the value of the expression 2z + 2w when z=7 and w=5

First solve for the slope, m using the two points given. It doesn't matter which point you choose as point 1 or 2 as long as you're consistent.

m = (y2 - y1)/(x2 - x1)

point 1: (6.4, 2.6)

point 2:  (5.2, 9)

m = (9 + 2.6)/(5.2 + 6.4)

m = (9 + 2.6)/(5.2 + 6.4)

m = 11.6/11.6

m = 1

put the newly found slope into the linear equation for m

y = (1)x + b

y = x + b

Now solve for the y-intercept, b

by putting one of the given points

9 = 5.2 + b

b = 9 - 5.2

b = 3.8

final equation:

y = x + 3.8

Step-by-step explanation:

The limit of a sequence is the value that its terms approach.

We can present the limit of the terms in the sequence as:

[tex]\lim_{n \to \infty}\dfrac{1}{n^n}[/tex]

To evaluate this limit, we can plug infinity (the value that n is approaching) into the expression:

[tex]\lim_{n \to \infty}\dfrac{1}{n^n}[/tex]

[tex]= \dfrac{1}{\infty^\infty}[/tex]

We know that infinity to any positive power is still infinity. So, this expression simplifies to:

[tex]= \dfrac{1}{\infty}[/tex]

Any real number, no matter how large, is inconsequential (infinitely small) compared to infinity. Therefore, this expression evaluates to 0:

[tex]= 0[/tex]

So, the limit of the sequence [tex]\sum_{n=1}^{\infty} \dfrac{1}{n^n}[/tex] is 0.

__

Note: You could also deduce the limit of this sequence by plugging in larger and larger numbers:

[tex]\begin{array}{c | c | c}n & \text{seq. term} & \text{decimal} \\\cline{1-3} 2 & 1/4 & 0.25 \\3 & 1/81 & 0.012\\4 & 1/256 & 0.0039 \\5 & 1/3125 & 0.00032 \\... & ... & ... \\\infty & 1/\infty & 0\end{array}[/tex]

Answer:

2/3

Step-by-step explanation:

Answer:

276

Step-by-step explanation:

let x = the number

(2/3)x - 70 = 45 + (1/4)x

2/3x - 1/4x = 45 + 70

8/12x - 3/12x = 115

5/12x = 115

x = 115(12/5) = 276

Double check the answer:

(2/3()276) - 70 = 45 + (1/4)(276)

114 = 114    answer is correct!

The simplification of the given expression is:

[tex]\sqrt[3]{\frac{6c}{-125} } = -\frac{\sqrt[3]{6c} }{5}[/tex]

Here we have an expression with a cube root:

[tex]\sqrt[3]{\frac{6c}{-125} }[/tex]

We can distribute the cube root over the fraction, then we will get:

[tex]\sqrt[3]{\frac{6c}{-125} } = \frac{\sqrt[3]{6c} }{\sqrt[3]{-125} } = \frac{\sqrt[3]{6c} }{-5}[/tex]

That is the expression simplified.

The area of the shaded segement is approximately 1.68 square inches.

The complete question is:

What is the area of the shaded segment shown in O below?

Hints:

Area of shaded segment = Area of sector - Area of triangle

Area of sector = (θ/360) × πr²

Area triangle = 1/2 × b × c × sin(A)

Given that;

Area of segment = Area of sector - Area of triangle.

Area of sector = (θ/360) × πr²

Area triangle = 1/2 × b × c × sin(A)

From the diagram:

Plug the values into the above formula and simplify.

Area of segment = Area of sector - Area of triangle.

Area of segment = ( (θ/360) × πr² ) - ( 1/2 × b × c × sin(A) )

Area of segment = ( (30/360) × 3.14 × 12² ) - ( 1/2 × 12 × 12 × sin(30) )

Step-by-step explanation:

A situation that could follow a binomial distribution is the number of heads that occur when flipping a "fair-coin" multiple times.

A "Binomial-Distribution" is defined as a probability distribution that describes the number of successes in a fixed number of independent trials, where each trial has the same probability of success.

In this case, flipping a "fair-coin" is an independent trial with two possible outcomes (heads or tails), and the probability of getting a heads on any given flip is 0.5.

Each "coin-flip" is independent of the others, and the probability of getting a heads on any given flip is always the same which is "0.5",

So, this situation fits the requirements for a binomial distribution.

The "binomial-distribution" can then be used to calculate the probability of getting a certain number of heads out of a fixed number of flips. For example, if we flip a coin 10 times, the probability of getting exactly-5 heads can be calculated using the binomial distribution formula.

Step-by-step explanation:

Use the Fundamental Theorem of Calculus to solve this problem. Since f(x) is the derivative of 1/3 x^3 - 2x^2 + 3x - 5, you have:

f(x) = d/dx (1/3 x^3 - 2x^2 + 3x - 5) = x^2 - 4x + 3

To find f(-2), you substitute x = -2 into the expression for f(x):

Answer:

The answer as follows

Step-by-step explanation:

Part I:

The graph of f(x) is a parabola with its vertex at the origin, opening upward.

To graph g(x), we can start by shifting f(x) 3 units to the right and 2 units up, according to the equation g(x) = (x - 3)² + 2. This means that the vertex of g(x) will be at the point (3, 2).

We can create a table of values for g(x) to plot some points and draw the graph:

| x  | g(x) |

|----|------|

| 0  | 11   |

| 1  | 8    |

| 2  | 5    |

| 3  | 2    |

| 4  | 5    |

| 5  | 8    |

| 6  | 11   |

Using these points, we can draw the graph of g(x) as a parabola that has the same shape as f(x), but is shifted to the right by 3 units and up by 2 units:

Part II:

The graph of g(x) is the graph of its parent function, f(x), shifted 3 units to the right and 2 units up. This means that every point on the graph of g(x) is 3 units to the right and 2 units up from the corresponding point on the graph of f(x).

In other words, the transformation that was applied to f(x) to get g(x) is a horizontal shift to the right by 3 units and a vertical shift up by 2 units. This is reflected in the equation g(x) = (x - 3)² + 2.

The probability that the Yankees will win when they score fewer than 5 runs is about 0.102.

Let A be the event that the Yankees win, and let B be the event that the Yankees score 5 or more runs. We know that;

P(A) = 0.53

P(B) = 0.51

P(A and B) = 0.43

We want to find the probability that the Yankees win when they score fewer than 5 runs. This can be expressed as;

P(A and not B)

We can use the formula;

P(A and B)=P(B | A) × P(A)

to find;

P(B | A) = P(A and B) / P(A)

= 0.43 / 0.53

≈ 0.811

This means that given the Yankees win a game, the probability that they score 5 or more runs is about 0.811. Therefore, the probability that they win when they score fewer than 5 runs is;

P(A and not B) = P(A) - P(A and B)

= 0.53 - (0.811 × 0.53)

≈ 0.102

Therefore, the probability that the Yankees will win is 0.102.

Answer:

Dear Kindergarten students,

Today, I am here to talk to you about place value and why it is important. Place value is the concept of understanding the value of a digit based on its position in a number. In other words, the position of a digit determines its value.

Let's take the number 123 for example. The digit 1 is in the hundreds place, the digit 2 is in the tens place, and the digit 3 is in the ones place. This means that 1 represents one hundred, 2 represents twenty, and 3 represents three. So when we put these digits together, we get the number 123.

Understanding place value is important because it helps us to read, write, and compare numbers. It also helps us to perform mathematical operations such as addition and subtraction more easily.

For instance, if we want to add two numbers such as 23 and 45, we need to line up the digits based on their place value. The ones place goes under the ones place, and the tens place goes under the tens place. Then we can add each column separately to get our answer of 68.

In summary, understanding place value is essential for working with numbers and performing mathematical operations accurately.
