Answer:
![\boxed {\boxed {\sf x \approx 3.7}}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20x%20%5Capprox%203.7%7D%7D)
Step-by-step explanation:
Since we are given a right triangle, we can use the trigonometric ratios.
- sin(θ)=opposite/hypotenuse
- cos(θ)= adjacent/hypotenuse
- tan(θ)=opposite/adjacent
We have the angle 24 and the sides 9 and x. 9 is the hypotenuse because it's opposite the right angle. x is the opposite, because it as across from the 24 degree angle. So, we have:
Therefore, we must use sine.
![sin(24)= \frac{x}{9}](https://tex.z-dn.net/?f=sin%2824%29%3D%20%5Cfrac%7Bx%7D%7B9%7D)
We are trying to solve for the value of x, so we must isolate the variable. x is being divided by 9. The inverse of division is multiplication. Multiply both sides by 9.
![9*sin(24)= \frac{x}{9}*9](https://tex.z-dn.net/?f=9%2Asin%2824%29%3D%20%5Cfrac%7Bx%7D%7B9%7D%2A9)
![9*sin(24)=x](https://tex.z-dn.net/?f=9%2Asin%2824%29%3Dx)
![9*0.406736643=x](https://tex.z-dn.net/?f=9%2A0.406736643%3Dx)
![3.66062979=x](https://tex.z-dn.net/?f=3.66062979%3Dx)
Round to the nearest tenth. The 6 in the hundredth place tells us to round the 6 to a 7.

Answer:
L(xyz) = ( 1 , 3 , -7 )
L = x + 3y - 7z -3
Step-by-step explanation:
f (x,y,z) = xy + 2yz - 3xz
f (3,1,0) = (3) (1) + 2 (1) (0) - 3 (3) (0)
f (3,1,0) = 3
fx = y - 3z
f (3,1,0) = (1) - 3 (0)
fx = 1
fy = x + 2z
f (3,1,0) = (3) - 2 (0)
fy = 3
fz = 2y - 3x
f (3,1,0) = 2 (1) - 3 (3)
fz = -7
