Answer:
for polynomial 4x^2-2x+14, degree=2/ special name=trinomial
for 22(x^2)(y^2)-2x+14, degree=2/ special name= trinomial
for 7x+2, degree=2/ binomial
for 2(x^3)-6xy+13xy^2, degree=3/ trinomial
for a^3-8, degree=3/ binomial
Answer:61 degrees.
Step-by-step explanation: If you look at Line MN you will see 103 degrees on the left side. A line is 180 degrees so 180-103=77. Angle P is corresponding with the angle above. Becuase you want to find 2, you have to subtract 77 by 16 to get 61 degrees
Answer:
Time, t = 2 seconds
Step-by-step explanation:
The height of a flare fired from a 32-foot high platform can be modeled by the function :
Here, h is the height in feet above the ground and t is the time in seconds.
It is required to find the time taken by the flare to reach the ground. When its reaches ground, height covered by it equals 0 such that,
h = 0
Neglecting t = -1 seconds, the time taken by the flare to reach the ground is 2 seconds.
I'll try it.
I just went through this twice on scratch paper. The first time was to
see if I could do it, and the second time was because the first result
I got was ridiculous. But I think I got it.
You said <span><u>3sin²(x) = cos²(x)</u>
Use this trig identity: sin²(x) = 1 - cos²(x)
Plug it into the original equation for (x).
3(1 - cos²(x) ) = cos²(x)
Remove parentheses on the left: 3 - 3cos²(x) = cos²(x)
Add 3cos²(x) to each side: 3 = 4cos²(x)
Divide each side by 4 : 3/4 = cos²(x)
Take the square root of each side: <em>cos(x) = (√3) / 2</em> .
There it is ... the cosine of the unknown angle.
Now you just go look it up in a book with a table cosines,
or else pinch it through your computer or your calculator,
or else just remember that you've learned that
cos( <em><u>30°</u></em> ) = </span><span><span>(√3) / 2 </span>.
</span>
Suggestion:
The width is the x value and the hight is the y value.
Plot the points on the graph as decimal if that helps.
The point at the bottom left is the origin (0,0)
I hope this helps.
