You can fit 153 flowers in a circle with the diameter of 14. You find the area of the circle by doing pi times 7 squared.
Answer:
if we add 25 more women, we could get 60% women and 40%men
Given:
Two endpoints of a diameter of a circle:
P (-7, -10)
Q (3, 2)
a) To find the center of the circle, find the midpoint of the two points:
midpoint:
(x2 - x1 )/ 2 , (y2 - y1) / 2
x= (2 - (-7))/2 = 4.5
y= (3 - (-10))/2 = 6.5
Therefore, the center of the circle is at C(4.5, 6.5)
b) To find the radius of the circle, we need to find the distance between the two points and divide by 2.
d = √(y2-y1)^2 + (x2 - x1)^2
d = √(2-(-7))^2 + (3 - (-10))^2
d = 5√10 = diameter
r = d/2 = 5√10 /2
Answer:
A. 2 factors: 5 and (6+4x)
B. 5: 1 term
(6+4x): 2 terms
C: The coefficient is 4
Step-by-step explanation:
The factors are the parts of expression separate by multiplications, so there are 2 factors: 5 and (6+4x)
The terms of each factor are the terms separate by the sign + or -. So the term of the factor 5 is 1 and the terms of the factor (6+4x) are 6 and 4x
The coefficient of the variable term is the number that is beside the variable. The coefficient of x is 4.
Step-by-step explanation:
By Descrates' Rule of Signs,
x² + 99x + 127 changes sign 0 times.
Hence it has 0 positive roots.
Since the discriminant b² - 4ac is also positive, there are 2 real distinct roots.
Hence both the roots are negative. (B)
