Answer:

It was <u>2.00 p.m.</u> when Clara finished the hike.

Step-by-step explanation:

Given:

Clara hiked to the top of a mountain. She started the hike at 10:30 A.M.

It took 2 hours and 45 minutes to get to the top of the mountain and 45

minutes to hike back down.

Now, to find the time Clara finished the hike.

Clara started hike = 10.30 a.m.

It took 2 hours and 45 minutes to get to the top of the mountain.

So, we add the 2 hours and 45 minutes to 10.30 a.m:

As, 1 hour = 60 minutes.

10.30\ a.m+2\ hours+ 30\ minutes.

=12.30\ p.m+45\ minutes

=1.15\ p.m.

Now, to add the 45 minutes he took to hike down:

1.15\ p.m+45\ minutes

=2.00\ p.m.

Therefore, it was 2.00 p.m. when Clara finished the hike.

100m world record was completed at an average speed of 37.6 km/h. work out this speed in meters per second?
pickupchik [31]

Step-by-step explanation:

1 km = 1000 m

1 hour = 3600 s

so,

37.6 km = 37,600 m (still per hour or per 3600 s).

in 1 second now that is

37600/3600 = 10.44444444... m/s

Find ????⋅ ???? if |????|=3 , |????|=9 , and the angle between ???? and ???? is π2 radians.
mrs_skeptik [129]

Answer:

a{\cdot}b=0

Step-by-step explanation:

It is given that,

Magnitude of a A, |A|=3

magnitude of B, |B|=9

The angle betwern a and b is \dfrac{\pi}{2}\ rad=90^{\circ}

Dot product,

a{\cdot} b=|a||b|\ \cos\theta\\\\a{\cdot} b=3\times 9\times \ \cos(90)\\\\a{\cdot} b=0

So, a.b is equal to 0.

Answer

The vertex is at point (-3, -1)

The axis of symmetry is x = -3

Explanation

We are asked to find the vertex and axis of symmetry of the equation given.

f(x) = x² + 6x + 8

The vertex of a quadratic equation is the point where the graph of the quadratic equation changes from sloping negatively to sloping positively and vice-versa.

The axis of symmetry represents the straight line that divides the graph of the quadratic equation into two mirror parts that are similar to and are mirror images of each other. This axis of symmetry usually passes through the vertex.

To find the vertex, it is usually at the turning point where the first derivative of the quadratic equation is equal to 0.

(df/dx) = 0

f(x) = x² + 6x + 8

(df/dx) = 2x + 6

At the vertex

(df/dx) = 2x + 6 = 0

2x = -6

Divide both sides by 2

(2x/2) = (-6/2)

x = -3

We then insert this into the equation to get the corresponding f(x) value.

f(x) = x² + 6x + 8

f(-3) = (-3)² + 6(-3) + 8

= 9 - 18 + 8

= -1

Hence, the vertex is at point (-3, -1)

And since the axis of symmetry has to pass through the vertex,

The axis of symmetry is x = -3

Hope this Helps!!!
