The radius would be .5.
When the diameter of a circle is 1, the circle's circumference is equal to pi.
The area would be .79
I hope this helped you!
Brainliest answer is always appreciated!
Step-by-step explanation:
let father's age be f yr old and son age be s yr old
f = 5s -(1)
f + s = 60 -(2)
sub (1) into (2):
5s + s = 60
6s = 60
s = 10
f = 60 - 10 = 50
in 5 yr time, father age = 50 + 5 = 55
son age = 10 + 5 = 15
Answer:
option A.
y = (1/2)x - 2
Step-by-step explanation:
It is given that, line that passes through the points (2, –1) and (6, 1)
Slope m = (y₂ - y₁)/(x₂ - x₁)
= (1 - -1)/(6 - 2)
= (1 + 1)/4 = 2/4
= 1/2
<u>To find the equation of the line</u>
Equation of a line passing through the points (x₁, y₁) and slope m is given by,
(y - y₁)/(x - x) = m
Here (x₁, y₁) = (2, -1) and m = 1/2
(y - -1)/(x - 2) = 1/2
(y + 1) = (x - 2)/2
y = -1 + x/2 - 2/2
= -1 + x/2 - 1
= x/2 - 2
The equation of the line is,
y = (1/2)x - 2
The correct answer is option A.
y = (1/2)x - 2
-m-4=-13
-m=-13+4=-9
m=9
