Answer:

7.31 and 0.685

Step-by-step explanation:

x^2 -8x +5 = 0

use the quadratic formula

- (-8) + √(-8^2 -4(1)(5) / 2(1(

(8 + √(64 -20))/2

(8+√44)/2

8+6.63 / 2

14.63/2= 7.31

+7.31

(8- √44)/2 = 0.685

The formula for the volume of a quarter-sphere is simply one-fourth of the volume of the sphere. So the volume of a quarter-sphere:
V = (1/4) (4/3) (π r³)
or
V = (1/3) (π r³)

Since we are given with the radius of 70 feet, the volume is
V = (1/3) (π) (70³)
V = 359,189 cubic feet

Find the linearization L(x) of the function at a. f(x) = x^4 + 2x^2, a = 1
gregori [183]

The equation of the tangent line at x=1 can be written in point-slope form as

... L(x) = f'(1)(x -1) +f(1)

The derivative is ...

... f'(x) = 4x^3 +4x

so the slope of the tangent line is f'(1) = 4+4 = 8.

The value of the function at x=1 is

... f(1) = 1^4 +2·1^2 = 3

So, your linearization is ...

... L(x) = 8(x -1) +3

or

... L(x) = 8x -5

Use a special right triangle to express sin 45 degrees as a fraction
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

in a right angled triangle angles given are 45,90

Then third angle is also 45 °

as two angles are 45° each.

Then sides are also equal.

Let the equal sides be each =x

then hypotenuse=√(x²+x²)=√(2x²)=x√2

sin 45°=x/(x√2)=1/√2
