If you plug in 90 into theta, the expression becomes sin(180), which has a value of zero. Therefore 90 cannot be a solution to this equation. Hope this helps.
Answer:
The positive value of k that the function y = sin(kt) satisfies the differential equation y'' + 144y = 0 is +12
Step-by-step explanation:
To determine the positive values of k that the function y = sin(kt) satisfy the differential equation y''+144y=0.
First, we will determine y''.
From y = sin(kt)
y' = 
y' = 
y' = kcos(kt)
Now for y''
y'' = 
y'' = 
y'' = 
Hence, the equation y'' + 144y = becomes
+



∴ 
±
± 
∴
or 
Hence, the positive value of k that the function y = sin(kt) satisfies the differential equation y'' + 144y = 0 is +12
Answer:
f(n)=o.15n. is you answer
25%of 32 should be written as 32•25%.then you convert 25%to a decimal wich is 25/100=0.25,last you multiply 32• .25=8 . 8 of them aregoldfish
