Answer:
A = 45
B = 90
C = 45
Step-by-step explanation:
Isosceles triangles have two side that are the same and two angles that are the same. Since one angle, B, is a right angle, 90°, that means the other 2 angles, A & C, added together equal 90°.
Divide 90 by 2 and you 45° for both A and C.
The answer is 810
23*2.5=57.5
57.5*12=690
690+120=810
Answer:
a. 0.9 Hz b. 0.37 Hz
Step-by-step explanation:
The frequency of the simple pendulum f = (1/2π)√g/l where g = acceleration due to gravity and l = length of pendulum
a. Find the frequency of a pendulum whose length is 1 foot and where the gravitational field is approximately 32 ft/s2
To find f on Earth, g = 32 ft/s² and l = 1 ft
So, f = (1/2π)√(g/l)
f = (1/2π)√(32 ft/s²/1 ft)
f = (1/2π)√(32/s²)
f = (1/2π)(5.66 Hz)
f = 0.9 Hz
b. The strength of the gravitational field on the moon is about 1/6 as strong as on Earth.. Find the frequency of the same pendulum on the moon.
On the moon when acceleration due to gravity g' = g/6,
f = (1/2π)√(g'/l)
f = (1/2π)√(g/6l)
f = (1/2π)√[32 ft/s²/(6 × 1 ft)]
f = (1/2π)√(32/s²)/√6
f = (1/2π)(5.66 Hz)/√6
f = 0.9/√6 Hz
f = 0.37 Hz
Answer:
The given expression is written as 
Step-by-step explanation:
Given as :
The expression is written as x = 
Now foe 5 x , the expression is written as
×
Now <u>from base indices method </u>
here base is same so, power should be added
∴
Hence The given expression is written as , Answer
No. The additive inverse of a negative number is positive, and the additive inverse of a positive number is negative.
