Answer:
I don't know!
Step-by-step explanation:
The first thing to do is to clear t from both expressions and compare the value to verify if it is the same:
Expression 1:
sin t = .3
t = arcsin (0.3)
t = 0.3047
Expression 2:
cos t = .48
t = arccos (0.48)
t = 1.0701
Both expressions have a different value of t, therefore, both expressions do not satisfy the same number t.
answer:
It is not possible for the same value of t to be met: sin t = .3 and cos t = .48
Answer:
Step-by-step explanation: I think -5 would change to a positive 5 because of the distributive property. In the part -(2x-5), there is a invisible 1 next to the left parenthesis, so it would be -1(2x-5). Then you would distribute the -1 one to the 2x and the -5. So the thing would look like this: -2x+5.
Answer: -2
Step-by-step:
Plug in 8 for X and -4 for Y
-4=-1/4(8)
Multiply 8 into -1/4
-4=-8/4
Then factor
-4=-2
Add 2 to both side
-2=b
This problem requires the use of the chain rule: dy / dt = [dy / dx] * [dx / dt]
y = √x => dy / dx = 1 / (2√x)
<span>(a) Find dy/dt, given x = 16 and dx/dt = 7.
dy/dt = [ 1/(2√x) ] * 7 = [1/(2*4)] * 7 = 7/8
(b) Find dx/dt, given x = 64 and dy/dt = 8.
dx/dt = [dy/dt] / [dy/dx] = 8 / [1/(2√64) ] = 128
