Step-by-step explanation:
A lava rock falling for five seconds will reach a height of 122.5 meters.
The missing function is y = 1/2 gt².
<h3>What is a function?</h3>
A function is a remark, tenet, or regulation that establishes a relationship between the two parameters.
The height of lava fountains spewed from volcanoes cannot be measured directly.
Instead, their height in meters can be found using the equation is given as
y = 1/2 gt²
where y represents the height, g is 9.8, and t represents the falling time of the lava rocks.
Then the equation will be
y = 1/2 × 9.8 × t²
y = 4.9t²
Then the height in meters of a lava rock that falls for 5 seconds will be
y = 4.9 x 5²
y = 122.5 meters

Answer:
25.1 ft
Step-by-step explanation:
To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).
So essentially, apply to your calculator:
2(3.14)4=25.12
pretty simple! hope this helps!
Answer:
Step-by-step explanation:
The required t score would be determined from the t distribution table. In order to use the t distribution, we would determine the degree of freedom, df for the sample.
df = n - 1 = 50 - 1 = 49
Since confidence level = 99% = 0.99, α = 1 - CL = 1 – 0.99 = 0.01
α/2 = 0.01/2 = 0.005
the area to the right of z0.005 is 0.005 and the area to the left of z0.005 is 1 - 0.005 = 0.995
Looking at the t distribution table,
t score = 2.678
