Answer:
x-y-4=0
Step-by-step explanation:
x1=2
X2=8
y1=-2
y2=4
slope=y2-y1/x2-x1
=4-(-2)/8-2
=6/6
=1
eqn of line is given by:
y-y1=m(x-x1)
y-(-2)=1(x-2)
y+2=x-2
x-y-4=0
Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
Hence, this is the required solution.
Answer:
It's d. -4x^2 + 2x + 2.
Step-by-step explanation:
-4x^2 + 2x + 2.
------------------------
6x + 3 )-24x^3 + 0x^2 + 18x + 6
-24x^3 - 12x^2
--------------------
12x^2 + 18x
12x^2 + 6x
--------------
12x + 6
12x + 6
Answer:
3 years
Step-by-step explanation:
In this problem, the initial number of students at time t = 0 is
We know that the number of students increases by 5 % every year. This means that we can write the student's population as
where
t is the time, measured in years
Here we want to find after how many years t the student's population will exceed the maximum capacity of the school, which is
N = 1100
To solve the problem, we just put n = 1100 and we solve for t. We find:
Which means that the student's population reaches the maximum capacity of the school after 2.37 years. Since we want this number to be an integer, this means that the enrollment will exceed the capacity in 3 years.
