Answer:

y=6.15cm

total length covered 9.12cm

Step-by-step explanation:

From the equation of a parabola

Recall that:

Parabola->

y=ax^2+bx+c

& y= height rabbit jumps & x= length rabbit jumps

What is max height rabbit can jump?

Solving for the x coordinate of the vertex:

x=−b/2a

from  y=-0.296x^2+2.7x

Let a= -0.296 & b=2.7

x=−2.7/2(−0.296)

x=4.56

To find y coordinate  when x= 4.56

... y=-0.296x^2+2.7x

-0.296(4.56)^2+2.7(4.56)

y=6.15cm

The total length covered will be 9.12cm=2x

<h3>Answer:</h3>

y = 28

<h3>Explanation:</h3>

The base angles of the isosceles triangle are congruent, so the sum of angles is ...

34° + 34° + 4y° = 180°

... 4y = 180 -68 . . . . . divide by °, subtract 68

... y = 112/4 = 28 . . . . divide by the coefficient of y

The value for y is 28.

_____

You have not asked about x in either figure.

<em>First figure</em>

Since the angles are congruent, the sides are congruent. Then ...

... 6x -3 = 5x

... x = 3 . . . . . . add 3-5x

<em>Second figure</em>

The base angles of the isosceles triangle are congruent, so

... 34° = (x -5)°

... 34+5 = x = 39 . . . . . . . divide by °, add 5.

Answer:

1) The graph is as shown at the attached figure.

2) The line passes with (1,-3) and (2,-2)

Step-by-step explanation:

graph the line that passes with (3,-1) and has a y-intercept of -4

y-intercept is the value of y when x = 0

So, the line passes with (0 , -4)

The general form of the line  y = mx + c

Where m is the slope and c is y-intercept

given y-intercept = -4 ⇒ ∴ c = -4

using the other point to find m

So, when x = 3 , y = -1

So,  -1 = 3m - 4

Solve for m

3m = -1 + 4 = 3

m= 3/3 = 1

So, the equation of the line ⇒ <u>y = x - 4</u>

See the attached figure which represents the graph of the line

As shown at the graph the line passes through the points <u>(1,-3) and (2,-2)</u>
