Find the coordinates of point B on AC such that AB is 2/7 of AC

Mathematics
1 answer:
Vesnalui [34]3 years ago
3 0

Answer:

Coordinates of B are (-3,-2)

Step-by-step explanation:

AC in the horizontal direction is 14, so AB in the horizontal direction is 2/7 of 14 which is 4.

​AC in the vertical direction is 7, so AB in the vertical direction is 2/7  of 7, which is 2.

To find the coordinates of B, you move right 4, and up 2 from A towards C.

A bus covers a distance of 2.45 km in 2 min. What is the speed of bus?​
Vladimir [108]

Answer:

The speed of the bus is 74.242 kilometers per hour.

Step-by-step explanation:

Let suppose that bus runs at constant speed and that speed is measured in kilometers per hour. Then, the speed of the bus (v), in kiometers per hour, is determined by following kinematic expression:

v = \frac{s}{t} (1)

Where:

s - Travelled distance, in kilometers.

t - Time, in hours.

If we know that s = 2.45\,km and t = 0.033\,h, then the speed of the bus is:

v = \frac{s}{t}

v = 74.242\,\frac{km}{h}

The speed of the bus is 74.242 kilometers per hour.

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid t
elena-14-01-66 [18.8K]

Answer:

<em>AD is 6.5 units</em>

Step-by-step explanation:

Find the diagram attached.

From the diagram, you can see that the dotted triangle is a right angled triangle with side AD as the hypotenuse.

To get AD, we will use the pythagoras theorem as shown;

Hyp² = Opp² + Adj²

AD² = 6²+2.5²

AD² = 36 + 6.25

AD² = 42.25

AD = √42.25

<em>AD = 6.5</em>

<em>Hence the measure of length segment AD is 6.5 units</em>
