The enrollment of a school was 1200. Since then, it has increased at a rate of 35 students per year. Write an equation to repres
Romashka [77]

The general equation to represent the enrollment of the school each year after 2000  = 1200 +35 n    

where n = number of years after 2000.

Step-by-step explanation:

Here, according to the question:

The initial number of students enrolled in the school = 1200 students

The number of students increased each year  = 35 students

Now if the initial year is 2000, then the number of student in the first year

= Initial enrollment  +  ( n  x Number of students increasing each year )

where n : The total number of years after 2000

So, the number of students in first year after 2000 for n = 1 is

1200 + ( 1 x 35)  = 1235

The number of students in second year after 2000 for n = 2  is

1200 + ( 2 x 35)  = 1270

The number of students in third year after 2000 for n = 3 is

1200 + ( 3 x 35)  = 1305

Hence, the general equation to represent the enrollment of the school each year after 2000  = 1200 +35 n    where n = number of years after 2000.

What are the x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of
Mrrafil [7]

Answer:

\left ( \frac{3x_2+5x_1}{8},\frac{3y_2+5y_1}{8} \right )

Step-by-step explanation:

Given: P is Three-fifths the length of the line segment from K to J

To find: x- and y-coordinates of point P on the directed line segment from K to J

Solution:

Section formula:

Let point K and J be (x_1,y_1)\,,\,(x_2,y_2) such that the point p(x,y) divides KJ in ratio m:n

Then coordinates of point  P are given by \left ( \frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n} \right )

Take m:n=3:5

So,

coordinates of point P = \left ( \frac{3x_2+5x_1}{3+5},\frac{3y_2+5y_1}{3+5} \right )=\left ( \frac{3x_2+5x_1}{8},\frac{3y_2+5y_1}{8} \right )

Find the circumference and area of a circle with a diameter of 14 inches. Leave your answers in terms of pi. C = 14π; A = 49π. C
Olenka [21]
Given:
diameter = 14 inches
radius = 14 inches / 2 = 7 inches

Circumference of a circle = 2 π r = 2 * π * 7inches = 14 inches * π

Area of a circle = π r² = π * (7in)² = π * 49in² 

C = 14π    and   A = 49π
