Which expression can be used to determine the length of segment AB? On a coordinate plane, triangle A B C has points (4, 3), (ne

JulijaS [17]

Answer:

StartRoot 2 squared + 6 squared EndRoot

Step-by-step explanation:

we have

A(4,3) and B(-2,1)

we know that

the formula to calculate the distance between two points is equal to

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

substitute the given values

$AB=\sqrt{(1-3)^{2}+(-2-4)^{2}}$

$AB=\sqrt{(-2)^{2}+(-6)^{2}}$

$AB=\sqrt{40}\ units$

therefore

StartRoot 2 squared + 6 squared EndRoot

How can a triangular prism have a greater volume than a rectangular prism?

son4ous [18]

Answer:

Step-by-step explanation:

Assume that the two prisms have bases of equal area.

Then the volume of the rectangular prism is V = (base area)(height).

The volume of the triangular prism is V = (1/3)(base area)(height)

We could compare the two volumes by creating the ratio inequality

(1/3) (base area)(t-height)

------------------------------------------

(base area)(r-height)

The triangular prism will have the greater volume for (1/3)((t-height) > r-height.

Angles A and B are complementary and in ratio of 3:6. What is the measure of each angle

pashok25 [27]

complementary angles add up to 90°, so therefore we know that ∡A + ∡B = 90°, and also they are in a ratio of 3:6.

$\bf \cfrac{A}{B}=\cfrac{3}{6}\implies \cfrac{A}{B}=\cfrac{1}{2}\implies 2A=\boxed{B}
\\\\[-0.35em]
~\dotfill\\\\
A+B=90\implies A+\boxed{2A}=90\implies 3A=90\\\\\\ A=\cfrac{90}{3}\implies \blacktriangleright A=30 \blacktriangleleft
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
2(30)=B\implies \blacktriangleright 60=B \blacktriangleleft$
