It is 1/6 or .16 I used Photomath
Let's write the parametric line
(x,y,z) = (0,2,8) + t(5,-1,4)
(5,-1,4) is called the direction vector of the line. It's normal to the plane
5x - y + 4z = constant
We get the constant by substituting the point (3,0,7),
5x - y +4z = 5(3) - 0 + 4(7) = 43
5x - y +4z = 43
38.38575 cm squared since if you multiply 97.5 * 0.3937, you get 38.38575
<u>Answer:</u>
A, (10⁵) (10⁻²) > 8⁹/8⁶
<u>Explanation:</u>
A, (10⁵) (10⁻²) > 8⁹/8⁶ = 10³ > 8³ True
B, (10⁵) (10⁻²) < 8⁹/8⁶ = 10³ < 8³ False
C, (10⁵) (10⁻²) = 8⁹/8⁶ = 10³ = 8³ False
