Before it rebounds n times we have the inequality
36 (3/4)^n < 1
(3/4)^n < 1/36
n ln 3/4 < ln 1/36
n < ln 1/36 / ln 3/4
n < 12.46
so n = 12
answer is 12 bounces
Answer:
6
Step-by-step explanation:
Given in the question that,
length of the diagonal of a square = 6√2
As we know that a square have all lengths equal in size and lengths are perpendicular to each other so to solve this question we will use pythagorus theorem
hypotenuse² = base² + height²
here,
hypotenuse is the diagonal of the square
base and height side length of the square
Plug value in the formula
6√2² = l² + l²
36(2) = 2l²
72 = 2l²
l² = 72/2
l² = 36
take square root on both sides of the equation
l = √36
<h3>l = 6</h3>
You can always treat such examples as an equation;
(90+96+86+92+X)/5=90
X is the desired score, 5 is the number of tests. As you can see, it is the usual equation for getting the mean value which the sum of the values over their number.
now; 90+96+86+92+X=90*5
X=90*5-(90+96+86+92)
X=86.
Hope this helps.
Answer:
4, 2
Step-by-step explanation:
The formulas for 180 clockwise and counterclockwise wise is -x,-y since both of them are negative they would become positive because -x * -x = + same with y.
