Answer:
(-21,-19)

Standard form
Step-by-step explanation:
We are given the equation of circle

General equation of circle:

Centre: (-g,-f)
Radius: 
Compare the equation to find f, g and c from the equation



Centre: (-21,-19)
Radius (r) 
Standard form of circle:

The centre of circle at the point (-21,-19) and its radius is
.
The general form of the equation of a circle that has the same radius as the above circle is standard form.
We know, 1 g = 1000 mg
so, 1 mg = 1/1000 g
then, 8,450 mg = 1/1000 * 8,450 = 8.450 g
In short, Your Answer would be: 8.450 Grams
Hope this helps!
Answer:
D.)
15040000 <= k <=19840000
Step-by-step explanation:
V = 1200 -0.00002k
Value V after one year falls in the range of $803.20 and $899.20.
Let's substract these values from 1200.
1200-803.20=396.80
1200-899.20=300.80
So it means that
0.00002k= 396.80
And
0.00002k= 300.80
So
0.00002k= 396.80
K= 396.80/0.00002
K= 19840000
And
0.00002k= 300.80
K = 300.80/0.00002
K= 15040000
So range is between
15040000 <= k <=19840000
Answer:
the cyclists rode at 35 mph
Step-by-step explanation:
Assuming that the cyclists stopped, and accelerated instantaneously at the same speed than before but in opposite direction , then
distance= speed*time
since the cyclists and the train reaches the end of the tunnel at the same time and denoting L as the length of the tunnel :
time = distance covered by cyclists / speed of cyclists = distance covered by train / speed of the train
thus denoting v as the speed of the cyclists :
7/8*L / v = L / 40 mph
v = 7/8 * 40 mph = 35 mph
v= 35 mph
thus the cyclists rode at 35 mph
Answer:
10 + 0.8 + 0.006 = 10.806
Step-by-step explanation:
Pick any two decimal numbers. The third one will be the difference between 10.806 and the sum of the two numbers you picked.
For example, choose 938.2 and 3.0055. Their sum is 941.2055. Then the third number that will make the sum be 10.806 is ...
10.806 -941.2055 = -930.3995
So, your three numbers could be ...
{938.2, 3.0055, -930.3995}
