Answer:

A

Step-by-step explanation:

Distance between 2 points

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

☆ (x₁, y₁) is the first coordinate while (x₂, y₂) I'd the second coordinate.

Length of RS

=  \sqrt{ {[ - 1 -( - 4)] }^{2}  + (9 - 1)^{2} }  \\  =  \sqrt{( - 1 + 4)^{2}  + 8^{2} }  \\  =  \sqrt{ {3}^{2}  + 64 }  \\  =  \sqrt{73}  \\ = 8.54 \: (3 \: s.f.)

Thus, RS is about 8.5 units.

What is the gcf of 27 and 72
Leya [2.2K]

Answer:

The GCF of 27 and 72 is 9

Step-by-step explanation:

prime factorization of 27 is 3*3*3

prime factorization of 72 is 2*2*2 by 3*3

3*3 is in both, and so we need to multiply that to get our GCF. 3*# is 9, so the GCF of 27 and 72 is 9

Help me please i need this urgent
Pavel [41]
In pythagoras's theorem, generally a is the shortest side, b is the second shortest and c is the hypotenuse: a^{2} +  b^{2} = c^{2}. However, there is a problem. The questions aren't actually possible without using sine, cosine, and tangent (which are mathematical ratios if you didn't know). I can help you with this but it will take time explaining.
