Answer:
Step-by-step explanation:
We are given that endpoints of a diameter at the points (7,2) and (-9,5).
Center of the circle is the mid point of diameter
So, first find the mid point of diameter
Formula : 
Substitute the values in formula
So, center of circle = (h,k )=(-1,3.5)
To find length of diameter :
Length of radius = r = 
Standard form of the equation of the circle : 
(h,k )=(-1,3.5)
Equation of the circle : 
Equation of the circle :
Hence the standard form of the equation of the circle with endpoints of a diameter at the points (7,2) and (-9,5) is
Answer: 8
Step-by-step explanation: Because a is perpendicular to b, the value of 9x + 18 = 90. If we subtract 18 from both sides, it becomes 9x = 72. Divide by 9 on both sides to get 8
6 large taxis x 7 people per large taxi = 42 people. In total there are 75 people. 75-42=32 people left. If you want to divide these people over small taxis, you divide 32 by 4, 32/4=8, so you need 8 small taxis
Answer:
d = 6.246 m
Step-by-step explanation:
Given that,
The distance around a circular pool is 39.25 m.
We need to find how does the lifeguard have to walk from the edge of the pool to the centre of the pool. It means we need to find the radius r of the circle.
ATQ,
Circumference = 2πr = 39.25 m
r is radius
So, the required distance is 6.246 m.
Answer:
(6, -5)
Step-by-step explanation:
Midpoint :
- (2, -2) = (x - 2 / 2, y + 1 / 2)
Equations formed :
- x - 2 / 2 = 2
2. y + 1 / 2 = -2
