Answer:
24649-17424=7225 UNITS
Step-by-step explanation:
This step implies that Lara was using the Pythagoras theorem to find the missing length of the right triangle.
a²+b²=c², taking a and b to be the two lengths adjoined by the right angle and c the hypotenuse.
Laura's step represents the step above.
157²=24649
132²=17424
157²-132²=c²
24649-17424=7225
50 has a two digit whole number, which means it has a place value of tens. 5 tens and ones.
5000 is a four digit whole number, which means it has a place value of 5000
5 thousands 0hundreds 0tens 0ones
5000 is 100 times greater than 50
well if
120-74=46
then 46 is the correct answer.
74+46= 120
46 more students can sign up for the field trip.
Answer:
Step-by-step explanation:
This is our quadratic:
where s(t) is the position of the object after all the stuff on the right side happens to it. If the object lands on the ground after all that stuff happens to it, its height is 0. Subbing in a 0 for s(t) gives us:
and if the object hits the ground at 21 seconds, we can sub in a 21 for each t to get this:
and do the math.
and solving for the height:
h = 1845.9 meters
The population standard deviation is 4.858 and the sample standard deviation is 5.4314
