Answer:

The average acceleration of the cyclist was 0.6 m/s².

Step-by-step explanation:

Acceleration:

The rate change of velocity per unit time is call the acceleration of the object.

$a=\frac{v-u}t$

u= initial velocity

v= final velocity

t= time taken change of velocity.

During the final 5 seconds of a race cyclist increased her velocity from 4m/s to 7 m/s

Here v= 7 m/s and u=4 m/s t=5 seconds

$\therefore a=\frac{7\ m/s-4 \ m/s}{5s}$

$=\frac{3}{5} \ m/s^2$

=0.6 m/s²

The average acceleration of the cyclist was 0.6 m/s².

Whic statement would best describe the graph of the function?

UNO [17]

First one.

Its a straight line with a slope of 6.

A line with a slope of 6 has a form of:

$y=6x+0$

So when $x=1$ , $y$ becomes $6\cdot1=6$ and so on.

Hope this helps.

I need help again.. please give me a real answer.

Reil [10]

Since the slope intercept form formula is y=Mx+b, your slope will be 3 and your starting point will be 0 because there’s no b. Mx is your slope and b is your y intercept.

A parabola with vertex (h, k) and a vertical axis of symmetry is modeled by the equation y - k = a(x - h)2. Determine the vertex

Inessa05 [86]

<span>y - k = a(x - h)²

</span><span>y = (x − 5)² + 8 -------> y-8 = (x-5)²

</span>y - k = a(x - h)²
y - 8 = (x - 5)²
Compare these formulas we can see that k=8, h =5.

Vertex (5,8).

Anika is hiking on a rectengular trail at the nation park there are four resting spots along the corners of the trail on the map

Drupady [299]

Answer:

The perimeter is 14 units

<em></em>

Step-by-step explanation:

Given

$A = (-2,2)$

$B = (1,2)$

$C = (1,-2)$

$D = (-2,-2)$

Required

Determine the perimeter

To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.

Distance (d) is calculated using:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

For AB

$A = (-2,2)$ --- $(x_1,y_1)$

$B = (1,2)$ --- $(x_2,y_2)$

$AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3$

For BC

$B = (1,2)$ --- $(x_1,y_1)$

$C = (1,-2)$ --- $(x_2,y_2)$

$BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4$

For CD

$C = (1,-2)$ --- $(x_1,y_1)$

$D = (-2,-2)$ --- $(x_2,y_2)$

$CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3$

For DA

$D = (-2,-2)$ --- $(x_1,y_1)$

$A = (-2,2)$ --- $(x_2,y_2)$

$DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4$

So, the perimeter (P) is:

$P = AB + BC + CD + DA$

$P = 3 +4 + 3 + 4$

$P = 14$

<em>The perimeter is 14 units</em>
