Y=4x - x²
dy/dx = 4-2x
dy/dx | x=1 : 4-2(1) = 4-2= 2
gradient= 2
Answer:
18ft![x^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D)
Step-by-step explanation:
so fine area you do side x side and divide by two
6 x 6= 36
36/2 = 18
Solution for F(x)=6x^2-900 equation:
<span>Simplifying
F(x) = 6x2 + -900
Multiply F * x
xF = 6x2 + -900
Reorder the terms:
xF = -900 + 6x2
Solving
xF = -900 + 6x2
Solving for variable 'x'.
Reorder the terms:
900 + xF + -6x2 = -900 + 6x2 + 900 + -6x2
Reorder the terms:
900 + xF + -6x2 = -900 + 900 + 6x2 + -6x2
Combine like terms: -900 + 900 = 0
900 + xF + -6x2 = 0 + 6x2 + -6x2
900 + xF + -6x2 = 6x2 + -6x2
Combine like terms: 6x2 + -6x2 = 0
900 + xF + -6x2 = 0 </span>
Answer:
![\frac{5}{6} = x](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D%20%3D%20x)
Step-by-step explanation:
![\frac{3}{7}x = \frac{5}{14} \\ \\ \frac{5}{14} \div \frac{3}{7} = \frac{5}{14} \times \frac{7}{3} = \frac{35}{42} = \frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7Dx%20%3D%20%5Cfrac%7B5%7D%7B14%7D%20%5C%5C%20%5C%5C%20%5Cfrac%7B5%7D%7B14%7D%20%5Cdiv%20%5Cfrac%7B3%7D%7B7%7D%20%3D%20%5Cfrac%7B5%7D%7B14%7D%20%5Ctimes%20%5Cfrac%7B7%7D%7B3%7D%20%3D%20%5Cfrac%7B35%7D%7B42%7D%20%3D%20%5Cfrac%7B5%7D%7B6%7D)
Use multiplication [inverse of division] to figure this out.
* 2⅓ = 7⁄3
