Answer:

$y + 2 = - (x - 4)$

Step-by-step explanation:

The graph passes through: (0,2) and (2,0)

The slope is

$\frac{0 - 2}{2 - 0} = - 1$

The equation of the line in point-slope form is given by:

$y-y_1=m(x-x_1)$

The graph passes through (4,-2).

We substitute the slope and this point to get:

$y - - 2 = - 1(x - 4)$

$y + 2 = - (x - 4)$

The first option is correct

13. A catapult launches a boulder wint an upward velocity of 122 feet per second the height of the boulder (h) in feet after t s

SashulF [63]

For this case we have the following expression:
h (t) = - 16t ^ 2 + 122t + 10
We look for the maximum of the function, for this, we derive:
h '(t) = - 32t + 122
We match zero:
-32t + 122 = 0
We cleared t:
t = 122/32
t = 3.8125 s
Then, the maximum height will be:
h (3.8125) = - 16 * (3.2185) ^ 2 + 122 * (3.2185) +10
h (3.8125) = 236.92 feet
Answer:
It takes the boulder to reach maximum height about:
t = 3.8125 s
the boulders maximum height is:
236.92 feet

Answer:

Point R is at (-40,30), a distance of 60 units from point Q

Step-by-step explanation:

Explanation

we will use below conditions

Type of transformation change to co-ordinate point

vertical translation up 'd' units (x, y) changes to (x, y +d)
vertical translation down 'd' units (x, y) changes to (x, y-d)
horizontal translation left 'c' units (x, y) changes to (x- c, y)

4. horizontal translation right 'c' units (x, y) changes to (x+ c , y)

now Given data is P( 20,-30) and in the graph Q(-40,-30)

Step1:-

Now we have to find 'R' point

Given data the point "R' is vertically above point Q so the point "Q' is moves vertically up with '60' units

now we will use the condition (1)

Q(-40,-30) is vertical translation up '60' units now changes the co-ordinate point is (-40 , -30+60)

The correct translation and The point R( -40 , 30)

Step2:-

Again in the given data "R" is at the same distance from point Q as point P is from point Q.

so given P point is (20 , -30)

now we translation 'P' also

vertically translation up at a distance '60' units and changes the new co-ordinate (20 , -30+60) that is (20,30) [ use above condition is (1)]

and again horizontal translation left '60' now changes (20 - 60 ,30)[ use condition (3)]

There fore the new co-ordinate is R( -40 , 30)

Final answer:-

Point R is at (−40, 30), a distance of 60 units from point Q

Juan wants to change the shape of his vegetable garden from a square to a rectangle, but keep the same area so he can grow the s

sergeinik [125]

The quadratic equation that would model this scenario is

$x^{2} = 2x(x-16)$

Let us take the side of the square = x

Area of the square = x²

Length of the rectangular garden = 2x

Width of the rectangular garden = x-16

So, the area of the new vegetable garden = length*width

Area of the new or rectangular vegetable garden = 2x(x-16)

<h3>What is a quadratic equation?</h3>

The polynomial equation whose highest degree is two is called a quadratic equation. The equation is given by $ax^2+bx+c$ coefficient $x^{2}$ non-zero.

Since it is given that

Area of square garden = area of the rectangular garden

$x^{2} = 2x(x-16)$

Thus, the quadratic equation that would model this scenario is

$x^{2} = 2x(x-16)$
