Answer:
no
Step-by-step explanation:
We can use the Pythagorean theorem to check
a^2 +b^2 = c^2
11^2+13^2 = 17^2
121+169 =289
410 does not equal 289
This is not a right triangle
Answer:
a(n) = 9·6^(n-1)
Step-by-step explanation:
The general term a(n) of a geometric sequence with first term a(1) and common ratio r is given by ...
a(n) = a(1)·r^(n-1)
Your sequence has first term 9 and common ratio 54/9 = 6, so the function describing it is ...
a(n) = 9·6^(n-1)
Answer:
Speed is 171.6 ft/s and distance is 1716 feet
Step-by-step explanation:
Given that,
The speed of a parachute = 117 miles per hour.
1 mph = 1.47 ft/s
117 mph = 171.6 ft/s
We need to find the distance it travel during 10 s. We know that the distance covered is equal to the product of speed and time taken. So,
d = vt

Hence, this is the required solution.
Answer:
65/56 = 1 9/56
Step-by-step explanation:
7x. Try to ignore the X's for a second and think of the problem as -12+5 (aka 5-12). The answer to that is 7. now add the x back again to get: 7x
