Digiron [165]

Answer:

the answer is 2.9 x 10^0 and 3.2 x 10^-2

Step-by-step explanation:

10^0 is equal to 1 so 2.9 x 10^0 is really 2.9 times 1 which is less than 3

if i could get brainliest answer that would be great!

10^-2 is a exponential that makes a number go down so 3.2 going down is less than 3

4) the distance between the x-values is 3 and the distance between the y-values is 4

3² + 4² = d²

9 + 16 = d²

25 = d²

√25 = d

5 = d

Answer: C

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

d = $\sqrt{(-2 - (-3))^{2} + (2 - (-4))^{2} }$

d = $\sqrt{(-2 +3)^{2} + (2 +4)^{2} }$

d = $\sqrt{(1)^{2} + (6)^{2} }$

d = $\sqrt{1 + 36}$

d = $\sqrt{37}$

d = 6.1
