Answer:
135° and 225°
Step-by-step explanation:
basically you want to find the value of x between 0 and 360 in this equation
cos x/2 = -(√2)/2
assume x/2 as n, so
cos n = -(√2)/2
n = 45°
then remember the quadrant system
0-90 1st quadrant, all is POSITIVE
90-180 2nd quadrant, only SIN has positive value
180 - 270 3rd quadrant, only TAN has positive value
270 -360 4th quadrant, only COS positive here.
so if you try to find negative value look into 2nd and 3rd quadrant that related 45° to x-axis (0°or 180°)
so the value of x is
180 - 45 = 135° (2nd quadrant) and
180 + 45° = 225° (3rd quadrant)
Here is the answer to the given problem above.
Here is the exponential function to model this situation:
<span>f(x) = 420(0.79)x
Now, solve with the given values.
</span><span>P(t)=420×(.79<span>)^t</span></span>
<span><span>P(5)=420×(.79<span>)^5</span>=129
So the answer would be 129 animals.
Hope this answer helps. Thanks for posting your question!</span></span>
Answer:
(3,4)
Step-by-step explanation:
A function can't have the x repeat so the only possible answer is (3,4)
Answer:
5,4
Step-by-step explanation:
hope this helps ^-^
I think the answer is 3
Explanation:
Since both equation are the same put them equal to each other
34x+3=-3+36x
Subtract 34x 36x-34x=2x
Then add three to both sides
So, 2x=6 Then divide x=3
