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,

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

If f(x) = 2x + 3, what is f(-2)?<br>evaluate a linear function

jok3333 [9.3K]

Answer:

The answer is bellow

Step-by-step explanation:

The -2 is the x so you would put it in like so

2(-2) + 3

So you would get

-4+3

Which would give you

Jerome has 1/2 of the group's video games at his house. Mario has 2/5 of the group's video games at his

larisa86 [58]

Answer:

9/10

Step-by-step explanation:

you find the lowest common denominator in this case is 10

then you take 1/2 and multiply it by 5 both the bottom and top and then you should get 5/10

next you do the same with 2/5 but this time to the get the denominator to 10 you multiply by 2 again multiply both bottom and top and you should get 4/10

now you just add 4/10 and 5/10 together and you get 9/10 or 0.9 as a decimal
