Answer:

[tex]y-45=5(x-9)[/tex]

Step-by-step explanation:

Definition of the variables:

Given information:

As the rate of change is constant and linear, the rate of change is the slope of the line.  Therefore, the slope is 5.

At hour 9 (x-value) the company had produced 45 (y-value) goods.  Therefore, this can be represented by the point (9, 45).

[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Point-slope form of a linear equation}\\\\$y-y_1=m(x-x_1)$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $(x_1,y_1)$ is a point on the line.\\\end{minipage}}[/tex]

Substitute the found slope and point into the point-slope formula:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-45=5(x-9)[/tex]

Therefore, the equation that correctly represents the goods produced by the company after x hours is:

[tex]\boxed{y-45=5(x-9)}[/tex]

Step-by-step explanation:

The quadratic parabola equation is represented as;

Therefore, if the given vertex (2,-5) and the other given point (-1,-1), substitute into the equation and solve for the constant ''a'':

Hence, the equation for the parabola:

Now, for the line since it is a horizontal line, the equation would be:

8(11 + 2r) = 126r + 3​

first open the parenthesis

88 + 16r = 126r + 3

88 - 3 = 126r - 16 r

85 = 110r

divide both-side of the equation by 110

85/110 = r

r= 17/22

The equation is -2n - 7.3 = 16 1/2

The value of the variable n = -11.9

STEP - BY - STEP EXPLANATION

What to find?

• Write the equation of the given statement.

• The value of n.

Given:

find the value of your variable. 7.3 less than -2 times a number is the same as 16 1/2. n=?​

To solve follow the steps below:

Step 1

Translate the given statement into equation.

Let n be the number.

-2n - 7.3 = 16 1/2

Step 2

Convert 16 1/2 to decimal.

-2n - 7.3 = 16.5

Step 3

Add 7.3 to both-side of the equation.

-2n = 16.5 + 7.3

Step 4

Simplify the right-hand side of the equation.

-2n =23.8

Step 5

Divide both-side of the equation by -2.

n = -11.9

Therefore, the value of the variable n = -11.9

From the rectangle TUVW, the coordinates of the points are shown below:

T(-5, -5), U(-1, -5), V(-1, 4), and W(-5, 4)

If TUVW is translated 5 units right and 4 units up, the coordinates of the new rectangle are in the form (x+5, y+4):

T'(0, -1), U'(4, -1), V'(4, 8), and W'(0, 8)

We have the following:

We know that 100% is the value of the purchase of $ 75, therefore, if we add 5%, it would be 105%, that is equal to 1.05, so we multiply the value of 75 by 1.05, and we are left with the following

Total value is $78.75 and taxes are 3.75

We have to identify the intervals where the function is concave upwards and where is concave downward.

We can differentiate them in a graph as:

We then have only one interval where the function is concave upwards: between x = -1 and x = 4. We can identify other intervals where the function is concave downwards and interrupted by discontinuities.

Then, we can write all the intervals as:

In a parallelogram, the opposite sides are parallel.

This means that RS is parallel to OT. So, the y value of S is the same as the y value of R, which is d, so y = d. Thus:

Now, we need to find x.

Since the sides RO and ST are also parallel, the x distance from O to R is the same as the x distance from T to S.

The x distance from O to R is

The x distance from T to S is

Since these x distances are equal, then:

Then, the coordinates of S are:

Which corresponds to option B.

Answer: the probability that at least two have seen a ghost or felt its presence is 0.527

Explanation:

In this scenario, it is either a person asked has seen seen a ghost or felt its presence or they have not. These outcomes are independent of each other. Thus, it's a binomial distribution. We would apply the formula for calculating binomial probability which is expressed as

P(x) = nCx * p^x * q^(n - x)

where

p = probability of success

q = 1 - p = probability of failure

n = sample size

x = number of successes

From the information given, we are concerned with the people that say they've seen a ghost or felt its presence. Thus,

p = 17% = 17/100 = 0.17

q = 1 - 0.17 = 0.83

n = 10

x = 2

We want to find P(x ≥ 2)

P(x ≥ 2) = 1 - [P(x = 0) + P(x = 1)

P(x = 0) = 10C0 * 0,17^0 * 0.83^(10 - 0) = 0.1552

P(x = 1) = 10C1 * 0,17^1 * 0.83^(10 - 1) = 0.3178

P(x ≥ 2) = 1 - (0.1552 + 0.3178) = 1 - 0.473

P(x ≥ 2) = 0.527

the probability that at least two have seen a ghost or felt its presence is 0.527

Let us use a diagram to illustrate the information, we have

Now, from the diagram, let the length of the uniform strip of floor around the rug be x, So, this means the length and width of the rug is

Now, since she can afford to buy a rug of 264 square feet for carpeting, this means that the area of the rug is 264, hence we have that

Solving for x, we have

Dividing through by 4 we have

So from our calculation, we go for x = 3, because 20 is large look at this

length cannot be negative, so we go for x = 3.

Hence the dimensions of the rug becomes

So the dimension of the rug should be 22 x 12 feet

First, we need to write our equation in standard form — the y should be on the left- hand - side and the x should be on the right- hand side.

The first step is to subtract x from both sides, doing this we get:

Now we divide both sides of the equation by 2 (this isolates the y on LHS), doing this gives us:

which can also be written as

The y-intercept is the point at which the line described by our equation intersects the y-axis. This intersection happens when x = 0; therefore, the y-intercept is

The x-intercept is the point at which the line intersects the x-axis. This happens when y =0; therefore, the x-intercept is

Now we see that the slope of the equation is -1/2 (the coefficient of x ). The y-intercept is y = 3 and the x-intercept is 6.

Supplementary angles add up to 180°

A+ B = 180

A is 9 times as large as B.

A = 9B

We have the system of equations:

A+ B = 180

A = 9B

Put the second equation into the first one, and solve for B

(9B)+ B = 180

10B = 180

B= 180/10

B = 18

Replace the value of B on any equation and solve for A:

A = 9B

A= 9(18)

A= 162

A= 162°

B=18°

To get x, we will use the equation below:

open the inner paremthesis

open the parenthesis

180 - x = 94

collect like term

180 - 94 = x

86 = x

90 represents the 100%

Let's call x to the number that represents the 40%

To find the 40%, we can use the next proportion:

Solving for x:

36 is 40% of 90

To find:

We need to find two points on the linear equation y-1=0 and to plot those points on graph.

Step by step solution:

We know that:

General coordinate of any two points on line y = 1:

= (x, 1)

So let us assume any two random points on the line:

= (1,1) and (2,1)

We will now mark them on the graph:

A parallelogram is a quadrilateral that has the following characteristics:

The opposite sides are parallel and congruent.

The opposite angles are congruent.

The consecutive angles are supplementary.

If any one of the angles is a right angle, then all the other angles will be at right angle.

The two diagonals bisect each other.

Since:

We can conclude that the answer is:

Yes; diagonals of a parallelogram bisect each other. ​

Triangles' resemblance is reflected by their congruence. If the matching sides and angles of two triangles match, the triangles are said to be congruent.

For triangles, there are five primary congruency rules: Side-Side-Side is an SSS criterion. The side-angle-side SAS criterion. Angle, Side, Angle is an ASA criterion. Angle-Angle-Side is an AAS criterion.

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

An isosceles triangle in geometry is one with at least two equal-length sides. It is sometimes stated as having exactly two equal-length sides and other times as having at least two equal-length sides, with the latter version adding the equilateral triangle as one of the possible configurations.
