H(t)=-16t²+500
0=-16t²+500
16t²=500
t²=31.25
t=5.9 seconds before the object hits the ground

Answer:
Isosceles Right Triangle
Step-by-step explanation:
We look at the sides first. Two sides are equal, which means that the triangle is isosceles (equilateral means three equal sides, and scalene means no sides equal). Then we look at the only angle indicated, which is the right angle. Thus, we come to the conclusion that the triangle is an Isosceles Right Triangle.
d1 = 51(t)
d2 = 71(8 - t)
d1 + d2 = 508
and now you just have to solve for t.
Answer:
Step-by-step explanation:
Given

The interpretation of the question, is to calculate the distance between the two given points.
This is calculated as:
Open bracket
<em>Hence, the distance between both is 11325ft</em>
Answer:
<u>A. Mean = 402.5</u>
<u>B. Variance = 77,556.25</u>
<u>C. Standard Deviation = 278.49</u>
Step-by-step explanation:
Let's calculate the mean, variance and standard deviation of the set of numbers given:
A. Mean = (45 + 340 + 400 + 825)/4 = 1,610/4 =<u> 402.5</u>
B. Variance [(45 - 402.5)² + (340 - 402.5)² + (400 - 402.5)² + (825 - 402.5)²]/4 = [(127,806.25 + 3,906.25 +6.25 + 178,506.25/4 =<u> </u><u>77,556.25</u>
C. Standard Deviation = √Variance = √77,556.25 =<u> 278.49</u>
