The zeros of this function is -4 and -8
Answer:
B and D
Step-by-step explanation:
A can't be correct because the length of a segment is always positive. B is correct because we have to take the absolute value of the distance between endpoints to find the length of the segment. C is not correct because AC is obviously longer than BC so how would AB + AC = BC? D is correct because it models the Parts Whole Postulate.
Answer:
m= 5n−28 over 4
Step-by-step explanation:
its supposed to be a fraction
The correct answer is 1 and 8 because 4 times 1 will be 1 and 8 times 4 equals 32 and will be 8
Answer:
Area = πr²
Circumference = 2πr
Step-by-step explanation:
When given the radius r ,
Area of a circle A = πr²
Circumference of the circle C = 2πr
When given diameter d,
Area of a circle A = πd²/4
Circumference of a circle = πd
To find the radius r and d from area A,
r = sqrt(A/π)
d = sqrt(4A/π)
To find the radius r and diameter d from a given circumference C,
r = C/(2π)
d = C/π
Where d = 2r
