Find the distance between points p (5, 1) and q (3,4)

DENIUS [597]

Answer:

D=3.60

Step-by-step explanation:

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (5,1)$

$(x_2,y_2) = (3,4)$

Replacing these values in the distance formula

$D =\sqrt{(5-3)^2+(1-4)^2}$

$D =\sqrt{(2)^2+(-3)^2}$

$D =\sqrt{4+9}$

$D =\sqrt{13}$

$D= 3.60$

What would the second point be with point (-2,-5) to get a line with the slope of -1

choli [55]

Answer:

A second point would be (-1, -6)

Step-by-step explanation:

Because the slope is -1, we know that for every number that x increases, we change y the amount of the slope. So, if we increase x by 1, we change y by -1.

x value

-2 + 1 = -1

y value

-5 - 1 = -6

you burn 10 calories each minute you jog.What integer represents the change in your calories after you jog for 20 mins

Hoochie [10]

The total calories burnt in 20 minutes are 200

Step-by-step explanation:

We have to do simple multiplication to find the number of calories burnt.

Given

Number of calories burnt in one minute = c = 10

Time = t = 20 min

So the total number of calories burnt in 20 minutes will be:

$C_t = c * t\\= 10 * 20\\=200\ calories$

Hence,

The total calories burnt in 20 minutes are 200
