Answer:
0.252 m
Step-by-step explanation:
At the fundamental frequency, a closed-end column has the same wavelength as an open-end column twice as long. Column B only needs to be half the length of Column A:
0.504 m/2 = 0.252 m
Range is the outputs possible
w(r(x))=(2-x^2)-2
w(r(x))=2-x^2-2
w(r(x))=-x^2
therefor the range is from 0 to -∞
Answer:
78.5 units
Step-by-step explanation:
To find the area of a circle the formula is πr"2"
First we have to find the diameter the find the radius. We already know that the circumference is 31.4 what we have to do now is work backwards. ( 31.4 / 3.14=10) If the diameter of a circle is 10 the radius is 5. now we just have to follow πr"2" to find the area of a circle. (5"2"= 25 x 3.14= 78.5 units)
Answer:
Solution:-
Frequency Distribution Frequency Mid values F*M
0 - 10 8 5 40
10 - 20 x 15 15x
20 - 30 10 25 250
30 - 40 11 35 385
40 - 50 9 45 405

Σf = 38+x Σfm = 1080+15x
______________________________________________________
Given Mean = 25.2
Mean = Σfm/Σf
25.2 = 1080+15x/38+x
25.2 × (38+x) = 1080+15x
957.6+25.2x = 1080+15x
25.2x - 15x = 1080 - 957.6
10.2x = 122.4
x = 122.4/10.2
x = 12
Missing frequency = 12 Answer
Sinα=height/length
length=height/sinα, we are given that α=20° and h=33 in
length=33/sin20° in
length≈96.49 in (to nearest hundredth of an inch)
