Answer:
Step-by-step explanation:
This root can be rewritten as:
Since 6487209 is a multple of 3, the expression can be rearranged as follows:
2162403 is also a multiple of 3, then:
720801 is a multiple of 3, then:
240267 is a multiple of 3, then:
80089 is a multiple of 283, then:
Answer:
w = 9.82
x = 66.73
Step-by-step explanation:
By applying tangent rule in triangle ABD,
tan(81°) =
6.31 =
w =
w = 9.82
Similarly,
tan(39°) =
0.81 =
0.81 =
9.82 + x =
x = 76.56 - 9.82
x = 66.74
Answer: a) -7/12 ft/s, -20 ft/s, -7 ft/s
b) 527/24 Ft²/s
c) 2/25 rad/sec
Step-by-step explanation:
a) b=7 ; a^2+b^2 = 25^2
a^2+b^2 = 625
Differentiate w.r.t = 2a (da/dt) + 2b ( db/dt) = 0
As found from above put a=24 b=7,15 and 24. You will get the reuqired answer.
b) Area of the triangle = 1/2 * b*h
differentiate wrt to time leads to the following relation:
c) sin (Θ) = b/25
differentiate it again to give
