If A = (7,9) and B = (3 , 12) what is the length of AB

V125BC [204]

Answer:

AB = 5 units

Step-by-step explanation:

Calculate the length using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+ (y_{2}-y_{1})^2$

with (x₁, y₁ ) = A(7, 9) and (x₂, y₂ ) = B(3, 12)

AB = $\sqrt{(3-7)^2+(12-9)^2}$

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

= $\sqrt{16+9}$

= $\sqrt{25}$

= 5

15/30 = n/34 round to the nearest tenth.

avanturin [10]

The equation given in the question has to be answered to the nearest tenth. The only thing that one should be careful about is the cross multiplication part. Other than that there is no difficulty in the given problem. Now let us get down to the equation in the question.
15/30 = n/34
30 * n = 15 * 34
30n = 510
n = 510/30
= 51/3
= 17
So the value of the unknown variable "n" comes out to be 17.
