[tex]\displaystyle\\Answer:\ \frac{7}{5}x +\frac{34}{5}[/tex]

Step-by-step explanation:

[tex]\displaystyle\\(-7,-3)\ \ \ \ (-2,4)\\\\\frac{x-x_1}{x_2-x_1}=\frac{y-y_1}{y_2-y_1} \\\\x_1=-7\ \ \ \ \ x_2=-2\ \ \ \ y_1=-3\ \ \ \ \ y_2=4\\\\\frac{x-(-7)}{-2-(-7)} =\frac{y-(-3)}{4-(-3)}\\\\\frac{x+7}{-2+7}=\frac{y+3}{4+3} \\\\\frac{x+7}{5} =\frac{y+3}{7} \\\\[/tex]

Multiply both parts of the equation by 7:

Answer:

7.071068 ≈ 7.07

Step-by-step explanation:

The distance, d,  between 2 points (x1, y1) and (x2, y2) is given by the formula

[tex]d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}[/tex]

The two points as determined from the graph are (1, 5) and (2, -2)

[tex]d = \sqrt {(2 - 1)^2 + (-2 - 5)^2}[/tex]

[tex]d = \sqrt {(1)^2 + (-7)^2}[/tex]

[tex]d = \sqrt {{1} + {49}}[/tex]

[tex]d = \sqrt {50}[/tex]

[tex]d = 7.071068[/tex]

It is true given the above logical analysis to state that RS = 2UV. This is known as a conditional statement also known as an If-then-statement.

A conditional statement (also known as an If-Then Statement) is a statement that begins with a hypothesis and ends with a conclusion.

A conditional statement can also be defined as "If this happens, then that will happen." A conditional statement's hypothesis is the first, or "if" element. While the "Then" is the Conclusion.

Hence, the hypothesis from the above statement is:

IF RS = ST and ST = 2UV [Hypothesis]

Then RS = 2UV [Conclusion]


Put differently we can say

A → B and B→C; then

The only student with the correct claim about the given quadratic equation is; Neil: The vertex is at (2, -9)

We are given the quadratic function;

f(x) = (x - 5)(x + 1)

1) The x-intercepts of the quadratic function are simply the roots of the quadratic function. Now, the roots are at; (5, 0) and (-1, 0). Thus, Annie's claim is not correct.

2) The y-intercept is the point at which x = 0. Thus;

f(0) = (0 - 5)(0 + 1)

f(0) = -5

y-intercept is at; (0, -5)

Thus, Jacob is wrong.

3) The x-coordinate of the vertex is;

x = -b/2a

The equation is; x² - 4x - 5

Vertex = -(-4)/(2 * 1) = 2

The least common multiple of 32, 48, and 16 is 96

The first step is to get the prime factors of each number

The prime factors of 32 are 2, 2, 2, 2 and 2.

The prime factors of 48 are  2, 2, 2, 2 and 3

The prime factors of 16 are 2,2,2 and 2

The least common multiple of 32, 48 and 16 can be calculated as follows

Answer:

Step-by-step explanation:

A statement which best describes the meaning of function f(150) is that: A. This is the average number of days the house stayed on the market before being sold for $150,000.

The average rate of change can be defined as a type of function that is used for describing the average rate at which a quantity either decreases or increases with respect to another quantity.

A function simply refers to a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable (x-value) to an output variable (y-value or f(x)).

In this scenario, the function f(150) can be evaluated as follows:

Function f(150) = 150 × p

Function f(150) = 150 × $1,000.

Function f(150) = $150,000

Therefore, the function f(150) simply means the average number of days this house stayed on the market before it was then sold for $150,000.

Step-by-step explanation:

In the picture, there is a square and a shaded region inside the square. The shaded portion has a 13.76 square meter area.

Given that,

In the picture, there is a square and a shaded region inside the square.

We have to find the shaded portion area.

The side of the square is 8cm.

Now,

First we see the unshaded region on the square is there are 4 unshaded regions.

In the figure u can see there is a unshaded region we named that has tile 1, tile2, tile 3, and tile 4.

If we restock them we can see that we got a circle with that 4 tiles.

Now, the side is 8 cm then the 1 tile will be of 4 cm.

So, the radius of the circle is 4 cm.

In the other picture we can see that the area of the shaded region is equal to area of square- area of circle.

Area of the shaded region =s²-πr²

Area of the shaded region =8²-π(4)²

Area of the shaded region =64-π(16)

Area of the shaded region =64-16π

Area of the shaded region =64-16(3.14)

Area of the shaded region =64-50.24

Area of the shaded region =13.76

Pairs of values that could be the number of grams of protein and fiber in the protein bar are:

10 grams of protein and 20 grams of fiber. That is, (10, 20)

and

15 grams of protein and 10 grams of fiber. That is, (15, 10)

From the question, we are to determine the pair of values that could be the number of grams of protein and fiber in the protein bar

From the given information,

The protein has 80 calories from p grams of protein and f grams of fiber

and

The equation that represents the relationship is

4p + 2f = 80

To determine the pair of values, we can determine the values of f for certain values of p

When p = 10

4p + 2f = 80

4(10) + 2f = 80

40 + 2f = 80

2f = 80 - 40

2f = 40

f = 40/2

f = 20

A pair of values is 10 grams of protein and 20 grams of fiber.

When p = 15

4p + 2f = 80

4(15) + 2f = 80

60 + 2f = 80

2f = 80 - 60

2f = 20

f = 20/2

f = 10

Thus,

Another pair of values is 15 grams of protein and 10 grams of fiber.

The properties of the function are:

The absolute value equation of the function is given as

y = |x|

On the incomplete table of values, we do not have any x values

So, we can make use of any x value

To do this, we make use of the following x values

x = -3, -1, 0, 1 and 3

Next, we substitute x = -3, -1, 0, 1 and 3 in the equation y = |x|

So, we have:

y = |-3| = 3

y = |-1| = 1

y = |0| = 0

y = |1| = 1

y = |3| = 3

When represented on a table of values, we  have

x | y

-3 | 3

-1 | 1

0 | 0

1 | 1

Possible outcomes are Head, Middle, and Tail.

Since all outcomes are equally likely, the probability of each event is same, therefore

P(Head) = P(Middle) = P(Tail)

P(C|A) is 2/3

A and B are independent

A and C are not independent

Part a

Finding the sample space, S

S = { (HH), (HM), (HT), (MH), (MM), (MT), (TH), (TM), (TT) }

Part b

Finding  P(B|A) and P(C|A):

n(B and A) = no. of outcomes in which the first toss is Middle and second toss is Tail = 1

n(A) = Total no. of events in which the first toss is Middle = 3

Therefore, P(B|A) = 1/3

n(C and A) = no. of outcomes in which the first toss is Middle and total no. of heads is zero = 2

n(A) = Total no. of events in which the first toss is Middle = 3

Therefore, P(C|A) = 2/3

Part c

Finding if A and B are independent, or if A and C are independent

Two events A and B are said to be independent when the occurrence of one event does not affect the occurrence of the other event and vice versa. In case of independent events,

P(A) = P(first toss is Middle) = 3/9 =1/3

P(B) = P(second toss is Tail) = 3/9 = 1/3

P(A and B) = P(first toss is Middle and second toss is Tail) = 1/9

P(A)*P(B) = (1/3)*(1/3)

= 1/9 = P(A and B)

Hence, we can say that events A and B are independent.

For A and C, we have,

P(A) = P(first toss is Middle) = 3/9

P(C) = P(total no. of Heads is 0) = 4/9

P(A and C) = P(first toss is Middle and total no. of heads is 0) = 2/9

P(A)*P(C) = (3/9)*(4/9)

= 4/27 P(A and C)

Hence, events A and C are not independent.
