Answer:
1st Circle
Radius = 9
Diameter = 18
Circumference = 2 × × r = 2 × 3.14 × 9 = 56.52
2nd Circle
Radius = 14
Diameter = 28
Circumference = 2 × × r = 2 × 3.14 × 14 = 87.92
:D

Answer:
The answer is "triangle ABC is not a right triangle".
Step-by-step explanation:
For a right-angle triangle:
Its square upon on longest or triangular edges is equivalent to the total of the other two squares
Its parameters indicated throughout the question are;
Square of lateral length
The square of lateral length
The square of lateral length
Thus, the longest side is C, as well as the size of the squares of its two sides, is
, lower than square
, hence, the ABC triangle is not correct. Its longest edge is consequently C.
Answer:
0.18 sec or 3.4 sec.
For second part, it will take 3.7 sec.
First part:
Set h(t) = 17and solve for t.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.
