Answer:
28÷4=7
Step-by-step explanation:
Answer:
x^2 + y^2 = 25
Step-by-step explanation:
The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can see that the center is (0, 0) by looking at the graph, and the radius is 5 because it is marked. Plugging these in we get:
x^2 + y^2 = 25
Answer:
the answer is 56.
Step-by-step explanation:
2 for every 4 = 1 for every two, so 28 multiplied by two.
Answer:
t = 1.41 seconds
Step-by-step explanation:
We know the height at which the coconut is, which is 64 ft, now assuming that we are on the ground, we know that gravity is equal to 32.1742 ft / s².
Gravity is an acceleration, we have that the acceleration is equal to:
a = v / t
but the speed v = d / t, replacing we have:
a = (d / t) / t
That is to say
a = d / t²
Now, solved for you we have:
t = (d / a) ^ (1/2)
Replacing the values, we are left with:
t = (64 / 32.17) ^ (1/2)
t = 1.41 seconds
therefore, the person has 1.41 seconds to escape.
