The system of equations 3x + 9y^3= -21, 13y^3+4x=-1 has exactly one solution.
drek231 [11]

Answer:

\huge\boxed{(-88,3)}

Step-by-step explanation:

\sf 3x + 9y^3 = -21  -------------------------- (1)

\sf 13y^3+4x= -1  -------------------------- (2)

Multiply Eq. (1) by 13 and (2) by 9

<u>Equation (1):</u>

\sf 13(3x+9y^3) = -21 * 13

\sf 39x + 117y^3=-273 --------------------(3)

<u>Equation (2):</u>

\sf 9(13y^3+4x) = -1* 9

\sf 117y^3 + 36x = -9 ------------------------(4)

Subtract Eq. (2) from (1)

\sf 39x+117y^3-117y^3 -36x=-273+9  

39x - 36x = -264

3x = -264

Dividing both sides by 3

x = -88

\rule[225]{225}{2}

<u>Put x = -88 in Eq. (1)</u>

3(-88)+9y³ = -21

-264 + 9y³ = -21

9y³ = -21 + 264

9y³ = 243

Dividing both sides by 9

y³ = 27

Taking cube root on both sides

y = 3

\rule[225]{225}{2}

Ordered Pair = (x,y) = (-88,3)

\rule[225]{225}{2}

Hope this helped!

A 20ft ladder is leaning against a building. If the base of the ladder is 6ft from the base of the building. What is the angle o
deff fn [24]

9514 1404 393

Answer:

  72.5° ≈ 73°

Step-by-step explanation:

The ladder length is the hypotenuse of the right triangle that has the distance from the building as its base and the height up the building as the height of the triangle. The given dimensions are those of the side adjacent to the angle and the hypotenuse.

The appropriate trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(angle) = 6/20

The inverse cosine function (arccos) is used to find the angle from its cosine.

  angle = arccos(6/20) ≈ 72.54°

The angle is 72.5° rounded to tenths, or 73° rounded to degrees.
