The graph of y=x^2-4x by drawing the line y=x-4

Answers

Answer:

the graph of y=x^2-4x is parabola as shown in the image

Step-by-step explanation:

The graph of [tex]y = x^{2} -4x[/tex] by drawing the line y=x-4

so this gives us that the line  y=x-4 satisfies the equation  [tex]y = x^{2} -4x[/tex]

To get points put y = x - 4 in the equation  [tex]y = x^{2} -4x[/tex]

so we get x -4 = x( x- 4)

x =1 and x - 4 = 0

from here we get x = 1,4

now put these values in y = x -4

From here we get y = -3,0

so the points are (1 , -3) and ( 4 , 0)

Plot these on graph and we get the straight line .

For equation  [tex]y = x^{2} -4x[/tex]

Step-by-step explanation:

In a physics class demonstration, a ball is dropped from the roof of a building, 72 ft above the ground. The height, h, in feet, of the ball above the ground is given by the function h = -16t2 + 72, where t is time in seconds.

Answers

The graph is shown below:

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given:

h(t) = -16t² + 72

For t=-1,

h(-1) = -16 * (-1)² +72

h(-1) = -16 +72= 56

Ordered pair is ( -1, 56)

For t=1,

h(1) = -16 * (1)² +72

h(1) = -16 +72= 56

Ordered pair is ( 1, 56 )

For t=2,

h(2) = -16 * (2)² +72

h(2) = -64 +72=  8

Ordered pair is ( 2, 8 )

For t=3,

h(2) = -16 * (3)² +72

h(2) = -144 +72=  -72

Ordered pair is ( 3, -72)

4x+x-10=90

Answer:

Step-by-step explanation:

Straight line angles:

     Angles on a straight line add up to 180°.

 90 + 4x - 10 + x = 180

 90 - 10 + 4x + x = 180

Combine like terms.

Subtract 80 from both sides,

                 5x    = 180 - 80

                    5x = 100

The length of a rectangle is twice its breadth. If its length is decreased half of the 10 cm and the breadth is increased by half of the 10 cm cm, the area of the rectangle is increased by 5 sq cm, more than 70 sq cm. Find the length of the rectangle.

Also....any armies, stays and blinkss?

Answers

Since the length of this rectangle is twice its breadth, the length is equal to 40 cm.

How to calculate the area of a rectangle?

Mathematically, the area of a rectangle can be calculated by using this formula:

Area = Length × Width

Based on the information provided, we have:

Its length is decreased half of the 10 cm ⇒ (length - 5)Its breadth is increased by half of the 10 cm ⇒ (breadth + 5)Its area is increased by 75 cm ⇒ (area + 5)

Substituting the parameters into the formula, we have:

LB + 75 = (L - 5)(B + 5)

2B² + 75 = (2B - 5)(2B + 5)

2B² + 75 = 2B(B + 5) - 5(B + 5)

2B² + 75 = 2B² + 10B - 5B - 25

5B = 75 + 25

5B = 100

B = 100/20

B = 20 cm.

For the length, we have:

Step-by-step explanation:

(f-g)(x) = f(x) - g(x) = (3x+1)-(x²-6) = -x² + 3x + 7

The value of (f - g)(x) is -x² + 3x + 7.

Now,

 (f - g)(x) = f(x) - g(x)

              = (3x + 1) - (x² - 6)

              = 3x + 1 - x² + 6

Subtract 3x to both sides

4x - 3x - 16 = 10

x - 16 = 10
