Answer:
Step-by-step explanation:
x³ - 4x² + 7x - 28 = <u>x³ - 4x²</u> + 7x - 7*4
= <u>x²(x - 4)</u> + 7(x - 4)
= (x - 4 )(x² + 7)
Answer:
x ≈ 46°
Step-by-step explanation:
Since the triangle is right use the sine ratio to solve for x
sinx = = , hence
x = ( ) ≈ 46°
44 square feet
Diameter (4) divided by 2 is radius (2).
SA = 2πr^2 + 2πrh
SA = 2 * 3.14 * 2^2 + 2 * 3.14 * 2 * 3
SA = 2 * 3.14 * 4 + 2 * 3.14 * 2 * 3
SA = 6.28 * 4 + 6.28 * 3
SA = 25.12 + 18.84
SA = 43.96
Round to the nearest tenth.
SA = 44 square feet

Firstly, This is what I think you know too. The numbers are always written like that (x,y). So, (1,9) and (4,9) , both of their y-axis are 9. Therefore, When a line is drawn, they intersect one another.
