If 25% is 80, 100% is 320. 60% of 320 is 192.
Next two numbers are 1, -1. So the sequence will be -13, 8, -5, 3, -2, 1, -1
Answer:
see explanation
Step-by-step explanation:
Using the sine/ cosine ratios in the right triangle and the exact values
sin30° =
, cos30° =
, then
sin30° =
=
=
=
( cross- multiply )
AB = 12
cos30° =
=
=
=
( cross- multiply )
2 AC = 12
( divide both sides by 2 )
AC = 6![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
1. 13.75= 0.25b +0.50
-0.50 -0.50
13.25 = 0.25b; divide both sides by 0.25 to isolate b and you get:
53 = b
2. 10w + 4w = -84
Add like terms!
14w = -84; divide both sides by 14 to isolate w and you get:
w = -6
To solve this problem shown in the image attached, you must apply the following proccedure:
1. You have the following quadratic equation:
2x^2-2x-12=0
2. When you factor the quadratic equation shown above, you obtain:
2(x^2-x-6)=0
2(x-3)(x+2)=0
3. Then, you obtain:
(2x-6)(x+2)=0
Therefore, as you can see, the correct answer is the Option C.
