Answer:

The distance between the two points is $\sqrt{26}$

Step-by-step explanation:

The formula of the distance between two points (x1, y1) and (x2, y2) is

d = $\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}$

∵ The points are (-1, 3) and (4, 2)

∴ x1 = -1 and x2 = 4

∴ y1 = 3 and y2 = 2

→ Substitute them in the formula of the distance above

∵ d = $\sqrt{(4--1)^{2}+(2-3)^{2}}$

∴ d = $\sqrt{(4+1)^{2}+(-1)^{2}}$

∴ d = $\sqrt{(5)^{2}+1}$

∴ d = $\sqrt{25+1}$

∴ d = $\sqrt{26}$

∴ The distance between the two points is $\sqrt{26}$

If R is the set of all integers, choose the set S that will make the following statement false.

olga55 [171]

Answer: 1 S = {−2, −1, 0, 1, 2}

Step-by-step explanation:

Integers are whole numbers that could be positive or negative .

This means that

R = { ... -3 ,-2 , -1 , 0 , 1 , 2 , 3 , 4 , ...}

S ⊆ R means that all elements of S is also an element in R , therefore :

S = { -2, -1 ,0, 1 , 2 ...}

Kati has of a bag of frozen fruit. She used of the fruit to make smoothies. Which equation represents the amount of fruit Kati u

shutvik [7]

Answer:

The amount of frozen fruit used to make smoothies is equal to the total number of frozen fruits minus the remainder of fruits after making smoothies.

Step-by-step explanation:

Let

Total number of frozen fruits = F

Let the amount of frozen fruits used for making smoothies = S

The remaining frozen fruits = R

Then

F - S = R

To get the amount of frozen fruits used to make smoothies, we make S the subject of the formula.

-S = R - F

S = F - R

That is, the amount of frozen fruit used to make smoothies is equal to the total number of frozen fruits minus the remainder of fruits after making smoothies.
