Answer:

Step 1: a = 1, b = -4

Step 2: x = 2, f(2) = -9

Step 4: (5,0) and (-1,0)

Step 6: f(0) = -5

On the graph the points plotted are (-1,0) , (0,-5) , (2,-9) , and (5,0)

In order to graph this function you need to get axis of simmetry (by dividing the number with the squared x between the other number with the x), the vertex where the function changes its direction and the x and y axes cutting points.

Write a linear equation that goes through the points (0,4) and (4,10). A. y =3⁄2x + 4 B. y =3⁄2x – 4 C. y =2⁄3x – 4 D. y =2⁄3x +
Elena L [17]

Answer:

A

Step-by-step explanation:

To write the equation, find the slope of the line using the two points. Find the difference in y values over the difference in x values.

\frac{y_2-y_1}{x_2-x_1} = \frac{10-4}{4-0}=\frac{6}{4}=\frac{3}{2}

Write the equation using the slope m=3/2 and the point slope form.

y-y_1=m(x-x_1)\\y-10=\frac{3}{2}(x-4)

This is the equation of the line. You can convert it to slope intercept form:

y-10=\frac{3}{2}(x-4)\\y-10 = \frac{3}{2}x - 6\\y=\frac{3}{2}x +4

HELP!!!!!!!!
insens350 [35]

The direction of the vector is - 21.8 N of E , Option B is the answer.

<h3>What is a Vector ?</h3>

A vector is an object with both magnitude and direction.

A vector is shown in the graph.

To determine the direction , The angle needs to be determined

The slope of the vector will give the direction of the vector

The vector starts from the point (1 , 1)

Another point on the vector (-4 , 3)

slope = -2 /5

It is making angle x with the line y = 1

tan x = -2 /5

x = - 21.8 N of E.

Therefore the direction of the vector is - 21.8 N of E , Option B is the answer.

Is 4 hours greater or less than 14,400 seconds? (Or equal too)
DochEvi [55]

Answer:

Equal to.

Step-by-step explanation:

The easiest way to figure this out is to convert 14,400 seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour. So, divide 14,400/60, which is 240. This is now 240 minutes. To figure out minutes into hours, divide 240/60, which is 4. 4=4, so 4 hours equals 14,400 seconds.

Hope this helps you out...have a good day c:
