Which is an x-intercept of the continuous function in the table?

Mathematics

Airida [17]3 years ago

we know that

The x-intercept is the value of the variable x when the value of the function is equal to zero

so

In the table we have

(-1, 0) is a x-intercept, because

For x=-1 the value of the function is equal to zero

(-6, 0) is a x-intercept, because

For x=-6 the value of the function is equal to zero

therefore

<u>the answer is</u>

the continuous function in the table has two x-intercepts

(-1, 0)

(-6, 0)

A x-intercept of the continuous function in the table is <u>(–1, 0) and (–6, 0)</u>

<h3>Further explanation </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

A linear equation is an equation with 2 variables

General formula

<h3>y-y1 = m (x-x1) </h3>

or

<h3>y = mx + c </h3>

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant m = Δy / Δx

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

\large{\boxed{\bold{m=\frac{y_2-y_1}{x_2-x_1}}}

Straight line equation, can be stated in:

  • y = mx
  • ax + by = ab
  • y = a
  • x = a
  • etc.

The graph of this equation is a line

It takes at least 2 points to draw a graph of the line equation in the coordinate plane

A discrete function consists of points that have been determined

If we extend the line in both directions we will get a continuous function

The x-intercept: the point in which a line equation crosses the x-axis (the value of x when y = 0, (x, 0))

The y-intercept: the point in which a line equation crosses the y-axis (the value of y when x = 0, (0, y))

To find the correct x-intercept for the continuous function of the answer choices above, is to select a pair of points that have the value y = 0, i.e. point (–1, 0) and (–6, 0)

Mrrafil [7]
X-intercept => 2x = 6 => x = 3
x-intercept is 3.

y-intercept => 3/2y = 6 => y = 4
y-intercept is 4.

z-intercept => 3z = 6 => z = 2
z-intercept is 2.

Kamila buys a dress for £30 in a sale. It was advertised "25%off". Kamila says"25% of £30 is £7.50 so i saved £7.50". Explain wh
sveta [45]

Answer:

She was wrong in her analysis because the sales discount of 25% is the discount on the original cost of the dress and not the purchasing cost of the dress as explained below:

Step-by-step explanation:

From the question:

Purchasing cost price of the dress = £30

However, this cost (£30) was after a 25% Sales Discount        

It, therefore, implies that £30 is equal to 75% of the cost price

75% of the original cost price  = £30

100% of the original cost price = (30 x100%)/75%

   Original cost price                 = £40

Therefore the 25% discount / savings on the cost

                                                     = £ (40-30)

                                                      = £10    

She saved £10 by buying the dress at £30 instead of the original cost of £40

1) An i staircase has a 10 inch vertical rise per step to get to the second floor of the house. If the angle of elevation is 30.
bezimeni [28]

Answer:

A)

Each landing is about 17 inches.

B)

The vertical rise from Floor 1 to Floor 2 is about 7 feet.

Step-by-step explanation:

Please refer to the attachment below. (I accidentally wrote 30.30 instead of 30.20. Please ignore that and sorry for any confusion.)

Part A)

So, we want to find the length of \ell.

Note that the angle of elevation, the vertical height, and \ell form a right triangle.

Since the vertical height opposite to our angle is 10, and we want to find the adjacent height, we can use the tangent ratio:

\displaystyle \tan(x^\circ)=\frac{\text{Opposite}}{\text{Adjacent}}

Therefore:

\displaystyle \tan(30.20)=\frac{10}{\ell}

Solve for \ell. Cross-multiply:

\displaystyle \ell\tan(30.20)=10

So:

\displaystyle \ell=\frac{10}{\tan(30.20)}=17.1817...\approx17\text{ inches}

The landing space per step is about 17 inches.

Part B)

We know that there are a total of 12 feet of horizontal space total for each landing.

12 feet is equivalent to (12)(12) = 144 inches.

Since each landing is 17.1817... inches, this means that we have 144/(17.1817...) = 8.38... or about 8 steps.

Since the vertical rise of each step is 10 inches, the vertical rise from the 1st Floor to the second will be 8(10) or 80 inches or 80/12 = 6.666... or about 7 feet.

1. Write the phrase as a rate in simplest form. 68 feet in 8 seconds
Solnce55 [7]
I may or may not understand, and I would hate to make you miss the answers, but I DO know that if you’re just looking for them to be simplified:

1.) 8 1/2

2.) 2/17 (already in its simplest form)

3.) 8 1/2

4.) 8 1/2

2b.) 2 1/4

3b.) 2 1/4

4b.) 2 1/4

If you need it in fraction form, I can also do that! I apologize if this isn’t what you need! If you can respond and tell me what you need, I can easily fix it! c:
