A person who studies volcanoes is studying the rate for a flow of lava. The coordinate plane below shows vector v, which represents the lava flow, in kilometers per week. image cce0006d99b7492a9cb2f1cd463ec009 Based on the coordinate plane, which of these is closest to the rate of the lava flow, in KILOMETERS PER HOUR? A 0.01 km/hr B 0.02 km/hr C 0.13 km/hr D 0.45 km/hr

answer: i believe it’s 245.04

step-by-step explanation:

answer: f = 32.2m

step-by-step explanation: that is the answer

c

step-by-step explanation:

i think because what else can be a sample of every member

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
