Mathematics
1 answer:
Wittaler [7]3 years ago
6 0

Answer:

It is right

Step-by-step explanation:

Because the hypotenuse must be greater than all the legs, we have that 17 is the hypotenuse. So, we want to determine if 8^2+15^2=17^2.

8^2=8*8=64\\15^2=15*15=225\\17^2=17*17=289\\225+64=289\\

This means the triangle is indeed right!

What is the fifth term of the sequence whose first term is 10 and whose common ratio is 1/2?
Cloud [144]

Answer:

D


Step-by-step explanation:

Common ratio of half means that to get each successive terms, you have to multiply the preceding term by half.

2nd term is 10*\frac{1}{2}=5

3rd term is 5*\frac{1}{2}=\frac{5}{2}

4th term is \frac{5}{2}*\frac{1}{2}=\frac{5}{4}

5th term is \frac{5}{4}*\frac{1}{2}=\frac{5}{8}

Let the speed off the walk way be x and speed of the walkway be y
x+y=6....i
x-y=2....ii
adding the above equation we get:
2x=8
thus
x=4 ft/s
and
y=6-4=2 ft/s
thus the speed off the walk way is 4 ft/s
the speed of the moving walkway is 2 ft/s
