Suppose we take the interval [−5,7] and divide it into 4 equal subintervals. Find the width Δn of each subinterval. Δn = If we n

lana66690 [7]

Answer:

$x_0=-5\\x_1=-2\\x_2=1\\x_3=4\\x_4=7$

Δn=3

Step-by-step explanation:

Remember, if we need to divide the interval (a,b) in n equal subinterval, then we need divide the distance (d) between the endpoints of the interval and divide it by n. Then the width Δn of each subinterval is d/n.

We have the interval [-5,7]. The distance between the endpoints of the interval is

$d=7-(-5)=12$ .

Now, we divide d by 4 and obtain $\frac{d}{4}=\frac{12}{4}=3$

Then, Δn=3.

Now, to find the endpoints of each sub-interval, we add 3 from the left end of the interval.

$-5=x_0\\x_0+3=-5+3=-2=x_1\\x_1+3=1=x_2\\x_2+3=4=x_3\\x_3+3=7=x_4$

So,

$x_0=-5\\x_1=-2\\x_2=1\\x_3=4\\x_4=7$
