Find the distance between the points (-6,-2), (2,7)

Readme [11.4K]

Answer:

$d=12.0416$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance d:

$d=\sqrt{(2-(-6))^2+(7-(-2))^2}$

$d=\sqrt{(2+6)^2+(7+2)^2}$

$d=\sqrt{(8)^2+(9)^2}$

$d=\sqrt{64+81}$

$d=\sqrt{145}$

$d=12.0416$

Solve for x 4^x/9^x=½

kirill115 [55]

Answer:

x = 0.85476

Step-by-step explanation:

4ˣ/9ˣ=½

9ˣ / 4ˣ = 2

(9/4)ˣ = 2

2.25ˣ = 2 .... aⁿ = x logₐx = n

log₂.₂₅2 = x

x = 0.85476

Alfonso and Lucas are 238 miles apart, traveling towards each other. If Lucas travels 21 mph and Alfonso travels 13 mph how long

Alex

Lucas equation for his location is x(t) = 13t.

Alfonso's equation is x(t) = 238 - 21t

If you equate these, you get:

13t = 238 - 21t =>

34t = 238

t = 7

So after seven hours they meet.
