What is the diameter of the circle whose center is at (6, 0) and that passes through the point (2, -3)?
pickupchik [31]

Answer:

10

Step-by-step explanation:

\left(x-h\right)^{2}+\left(y-k\right)^{2}=r^2

\left(x-6\right)^{2}+\left(y-0\right)^{2}=r^2\\

We used (2,-3)

\left(2-6\right)^{2}+\left(-3-0\right)^{2}=25

r^2=25\\ , so r = 5

But this one is asking for the diameter, and to find it. It's simply 2r.

2*5 = 10

dalvyx [7]

Answer:D. Raw chemicals

Step-by-step explanation: A value system in this context is the system which comprise of different processes or points where improvements or values are added to the initial materials as it flows along.

The starting point will be the point from where the raw materials are being introduced or added before the flow continue with consistent value addition.

This is similar to what happens in production or manufacturing process where the process starts with the addition of raw materials to the different points where value addition is taking place till it come out a finished product with improved value.

iVinArrow [24]

Answer:

10:02:24\ \text{pm}

Step-by-step explanation:

d = Distance to travel = 880 miles

s = Average speed of the car = 65 mph

Time taken to cover the distance is

t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{880}{65}\\\Rightarrow t=\dfrac{176}{13}\ \text{h}=13.54\ \text{hours}

Time the car stopped

3\times 10+60=90\ \text{minutes}=1.5\ \text{hours}

Total time of the journey

13.54+1.5=15.04\ \text{hours}

Converting 0.04\ \text{hours} to minutes

0.04\times 60=2.4

So, the total time taken for the journey is 15\ \text{hours and }2\ \text{minutes and }24\text{seconds}

Time when they reach their destination

7:30+15:2.4\approx 10:02:24\ \text{pm}
