Find all solutions of the equation algebraically. Check your solutions. (Enter your answers as a comma-separated list x^4-7x^2-144=0

Answers

Answer:

The solutions are: $x=4,\:x=-4,\:x=3i,\:x=-3i$

Step-by-step explanation:

Consider the provided equation.

$x^4-7x^2-144=0$

Substitute $u=x^2\mathrm{\:and\:}u^2=x^4$

$u^2-7u-144=0$

$u^2-16u+9u-144=0$

$(u-16)(u+9)=0$

$u=16,\:u=-9$

Substitute back $\:u=x^2$ and solve for x.

$x^2=16\nx=√(16)\n \quad x=4,\:x=-4$

$x^2=-9\nx=√(-9)\n \quad x=3i,\:x=-3i$

Hence, the solutions are: $x=4,\:x=-4,\:x=3i,\:x=-3i$

Equations
Solve T = C(9+ AB) for B

Answers

Answer:

Simplifying

T = C(9 + AB) * forB

Reorder the terms for easier multiplication:

T = C * forB(9 + AB)

Multiply C * forB

T = forBC(9 + AB)

T = (9 * forBC + AB * forBC)

Reorder the terms:

T = (forAB2C + 9forBC)

Solving

T = forAB2C + 9forBC

Solving for variable 'T'.

Move all terms containing T to the left, all other terms to the right.

Simplifying

T = forAB2C + 9forBC

Step-by-step explanation:

Simplifying

T = C(9 + AB) * forB

Reorder the terms for easier multiplication:

T = C * forB(9 + AB)

Multiply C * forB

T = forBC(9 + AB)

T = (9 * forBC + AB * forBC)

Assume the 72-gon is a regular polygon. The measure of one interior angle is how manydegrees, and the measure of one exterior angle is how many degrees?

Answers

9514 1404 393

Answer:

interior: 175°
exterior: 5°

Step-by-step explanation:

The sum of exterior angles is 360°, so the exterior angle can be easiest to find first.

exterior angle = 360°/72 = 5°

The interior angle is the supplement of this.

interior angle = 180° -5° = 175°

The measure of one interior angle is 175°; one exterior angle is 5°.
