Answer:
28.56 m²
Step-by-step explanation:
What we need to do for the quarter circle is use the following formula: 1/4(πr²)
(4 * 4) + 1/4(3.14 * 4²)
16 + 1/4(3.14 * 16)
16 + 1/4(50.24)
16 + 12.56
28.56 m²
The best approximation for the area of this figure is 28.56 m².
Answer:
![\frac{50}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B7%7D)
Step-by-step explanation:
Swap the fraction,
![5 *\frac{10}{7} = \frac{50}{7}](https://tex.z-dn.net/?f=5%20%2A%5Cfrac%7B10%7D%7B7%7D%20%3D%20%5Cfrac%7B50%7D%7B7%7D)
or around 7.142...
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
