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:
100$or 20.4 that is the answer
Answer:
No. This isn’t a function.
Step-by-step explanation:
Ok, functions have x values that only have 1 y value. It doesn’t matter if the y values have multiple x values.
So, first look at the x values, all of them have 1 y value but the number 6. Therefore, this does not represent a function.
The answer is the 2nd one.
Answer: 14.38%
Step-by-step explanation:
Worth of stock in Company A = $5990
Percent decrease = 20%
New worth = $5990 - (20% × $5990)
= $5990 - (0.2 × $5990)
= $5990 - $1198
= $4972
Worth of stock in Company B = $2450
Percent decrease = 8%
New worth = $2450 - (8% × $2450)
= $2450 - (0.08 × $2450)
= $2450 - $196
= $2254
Previous total worth = $5990 + $2450
= $8440
Total worth = $4972 + $2254
= $7226
The total percentage decrease in the investor's stock account will be:
= [($8440 - $7226) / $8440] × 100
=( $1214 / $8440) × 100
= 0.1438 × 100
= 14.38%
Third side must be greater than (12 -7) or 5 and less than (12 + 7) or 19
So, third side could be A C E or F
