Hello there!

(a + b)² = a² + 2ab + b²

= a² + b² + 2ab

= 16 + 2(8)

= 16 + 16

= 32

As always, it is my pleasure to help students like you!

The surface areas of two similar rectangular prisms are 361 m2 and 441 m2. What is the scale factor of the larger prism to the s
Elis [28]

Option C:

The scale factor of the larger prism to the smaller prism is \frac{21}{19}.

Solution:

Two rectangular prisms are similar.

Surface area of the smaller prism = 361 cm²

Surface area of the larger prism = 441 cm²

Scale factor of larger prism to smaller prism

                           $=\frac{\sqrt \text{{Surface area of larger prism}} }{\sqrt\text{{Surface area of smaller prism}  }}

                           $=\frac{\sqrt {441} }{\sqrt{361}}

                           $=\frac{\sqrt {21^2} }{\sqrt{19^2}}

Both square and square roots are cancelled, we get

                            $=\frac{21}{19}

The scale factor of the larger prism to the smaller prism is \frac{21}{19}.

Hence Option C is the correct answer.

Answer:

read below

Step-by-step explanation:

If you know tangent of theta is 5/3 and it is in the 3rd quadrant, then you know the sides will be going in the negative direction and the real values of the sides would be -5/-3. You can use pythagorean theorem to figure out that the hypotenuse would be sqrt(5^2+3^2) = sqrt(34). Then you can use soh cah toa: sin = opp/hyp, cos=adj/hyp tan = opp/adj. You know that opp = -5, adj = -3, and hyp = sqrt(34) For cosine theta, it would be -3/sqrt(34) and csc is just 1/sin so csc would be hyp/opp = sqrt(34)/-5.
