HELP ASAP PLEASE Some of the measurements of the triangular prism with a right triangle base are shown.
geniusboy [140]

Answer:

4*sqrt(2)

Step-by-step explanation:

lets use Pythagorean Theorem

a^2+b^2=c^2

4^2+4^2=c^2

16+16=c^2

32=c^2

|c|=sqrt(32)

|c|=sqrt(4*4*2)

|c|=4*sqrt(2)

c= ±4*sqrt(2)

since distance can't be negative, the answer is +4*sqrt(2) or just 4*sqrt(2)

If a sequence contains only whole numbers, which of these sequences could include the term 27?
erik [133]
Depending on the first term, the sequences
a_n=2a_{n-1}+1
\\
\\a_n=3a_{n-1}
\\
\\a_n=a_{n-1}+6
would work.

If the sequence began at 6, 
a_n=2a_{n-1}+1=6, 13, 27, ...

If the sequence began at 1, 
a_n=3a_{n-1}=1, 3, 9, 27, ...

If the sequence began at 3, 
a_n=a_{n-1}+6=3, 9, 15, 21, 27, ...

1)Circle 1 is centered at (−4, 5)(−4, 5) and has a radius of 2 centimeters. Circle 2 is centered at (2, 1)(2, 1) and has a radiu
galina1969 [7]

Figures of same shape and size are similar .Two circles  C1&C2 will be similar.

Circle 1 has a center of (-4,5) and circle 2 has a center of (2,1) .The x of the center is having the translation x+6 and the y  is having a translation of y-4.The center of the circle is dilated by 3 units.

The circles are similar because you can translate Circle 1 using the transformation rule (x+6,y-4 ) and then dilate it using a scale factor of 3.

2) Area of sector = \pi.r^{2}\alpha÷360.

Where α is the angle made at center.

Area of given sector= π(12)(12)(60)÷360 =24π.
