Step-by-step explanation:
The answer is C
If you use the other coordinates instead of point (8,7), then you will not get a right angled traingle, but you will get other types of triangles. If you use (8,7), you will get a 90° and therefore a right angled triangle.
Y= 4.5 because the length is less than 6=x.
Domain: x>-5 ; It goes on from -5.
Range: y>-1 ; It goes on from -1.
Function: Slope is 6/7 ;
<h3><u><em>
y=6/7 x , when x>-5</em></u></h3>
The height in meters of a lava rock that falls for 5 seconds will be 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
