The equation of a circle centered on origin is
x²+y²=r² where r is the radius, so r²=16 in our equation so the radius of the circle is 4
we now have a total of 8 45-45 right triangle with hypotenuse 4. a 45-45 right triangle with hypotenuse 4 has legs of length 2√2. our big square is then 4√2 on a side. square this to get the squares area, which is 32
I suppose we have to find the lengh of the sides.
Area = lenght × width
288 = (3x) × (2x+10)
288 = 3x (2x+10)
288 = 6x + 30x
288 = 36x
288/36 = x
8 = x
therefore the sides are
3x = 3×8 = 24 inches
2x+10 = 2×8 + 10 = 16 +10 = 26 inches
Answer:
Step-by-step explanation:
Given
Required
- Convert 6 lb to kg
- Convert 11kg to lb
To solve for (a), we make use of the second conversion unit:
Multiply both sides by 6
<em>Hence, a 6lb backpack weighs 2.724kg</em>
Solving (b): 11 kg to lb
Here, we make use of the first conversion unit
Multiply both sides by 11
<em>Hence, the cat weighs 24.2lb</em>
The function that you would use would be 26 + 0.15x = 41.30.
