The way to figure this one out is move the 81 over to the other side so you have the equation 16x^4 = 81. Since 81 is not divisible by 16 you have to think of another way to simplify. 16 is a perfect square, x^4 is a perfect square, and 81 is a perfect square. So take the square root of both sides to begin the simplification. 4x^2 = 9. Divide both sides by 4 to get x^2 = 9/4. 9 and 4 are both perfect squares, so undo the square on the x by taking the square root of both sides: x = +/- 3/2.
The two numbers that adds up to 23 and mutliplies to 26 are 1.19 and 21.808.
21.808 + 1.19 ≈ 23
21.808 × 1.19 ≈ 26
Answer:(f/g)(x)=(1+2x)/(1-3x) where x<>0
Step-by-step explanation:
f(x)= 1/x+2= (1+2x)/x , x<>0
g(x)=1/x-3=(1-3x)/x , x<>0
=>f(x)/g(x)= (1+2x)/(1-3x) , x<>0
Trapezoid Area = (Bases / 2) * Height
20 cm² = 5 * Height
Height = 4 cm
Answer:
(PI* radius^2 * height) / 3
Volume = PI * 49 * 9 / 3
Volume = 461.8141200777 cubic feet
Volume = 461.81 cubic feet (rounded)
