Answer:
Step-by-step explanation:
law of sines
Sin(A) / a = Sin(B)/b
where A = 24
a=BC
B= 59
b =AB
then
Sin(24)/a =Sin(59)/19
0.4067366 / a = 0.8571673 / 19
0.4067366 / a = 0.045114
0.4067366 / 0.045114 = a
9.015 = a
BC = 9.0 mi
Answer:
Step-by-step explanation:
The attached diagram shows the triangle ABC formed by the ladder with the wall of the house.
Triangle ABC is a right angle triangle. It has a 90 degree angle. The length of the ladder forms the hypotenuse(AC)of the triangle. This length can be determined by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
AC^2 = 22^2 + 5^2
AC^2 = 484 + 25 = 509
AC = √509
AC = 22.56
The slope of the ladder is
(change in y)/(change in x)
Slope = 22/5 = 4.4
Answer:
√6 is irrational.
Step-by-step explanation:
The square roots of the others are rational
sqrt 0.16 = 0.4
sqrt 900 = 30
sqrt25 = 6.
Answer: 3
Step-by-step explanation:
Answer:
As 2.551 < 3.84 therefore we reject H0.
As 44.803 > 4.46 so we accept null hypothesis.
Step-by-step explanation:
The answer is attached.
There are three judges so v1 = 3-1= 2 and v2 = (4*2)= 8
There are five gymnasts so v1 = 5-1= 4 and v2= (4*2)= 8
For alpha = 0.05 we find the value of F1 and F2 from the table.
