Answer: It represents decay.
Step-by-step explanation:
Because 0.5 is less than 1, it is constantly decaying because multiplying by a fraction of a number gives you less than what you started with.
Ok so we can put this into terms as x. Eli is x. Sarah is 2x. Ashley is x+2x aka 3x. Hazel is 3*2x aka 6x.
Add them all up x+2x+3x+6x=888 aka 12x=888 divide 12 from each side. Gives you x=74
Eli travels 74 miles.
Sara travels 74*2 aka 148
Ashley travels 3*74 aka 222
Hazel travels 74*6 aka 444
The unit circle is represented below:
As can be observed in the figure above, for an angle (t), the relation between the trigonometric functions and x and y components is:
x = cos(t)
y = sen(t)
x is positive in the first and in the fourth quadrant. Thus, cos (t) will be positive for angles in the first and fourth quadrant.
y is positive in the first and in the second quadrant. Thus, sin (t) will be positive for angles in the first and second quadrant.
Answer:
1,092 square cm
Step-by-step explanation:
I hope this helps you.
Area of a triangle = 1/2base x perpendicular height so...
1/2(26) x (8) = 104
104 x no. of sides (4) = 416
416 + (26x26) = 1,092
You can do synthetic division twice immediately (or once if you know how to handle x^2 - 25 all at once. I'll use 2 divisions. x^2 - 25 is (x + 5)(x - 5). Both of them are zeros to the given equation which means that x = +5 and
x = - 5 are both zeros of the given quartic.
5 1 -2 -33 50 200
5 15 -90 -200
=====================================
1 3 -18 -40 0
What you have now is x^3 + 3x^2 - 18x - 40 = 0
Do another synthetic division
-5 1 3 -18 -40
-5 10 40
============================
1 -2 -8 0
The result is
x^2 - 2x - 8 = 0 which factors.
(x + 2)(x - 4) = 0
Answer
The factors are (x + 2)(x - 4)(x + 5)(x - 5) = 0
Long division
x^2 + 0 + 25 ||x^4 - 2x^3 - 33x^2 + 50x + 200 ||x^2 - 2x - 8
x^4 + 0 + 25x^2
==================
-2x^3 -8x^2 + 50x
-2x^3 + 0 + 50x
=================
-8x^2 + 0 +200
-8x^2 + 0 + 200
==================
0
