Step-by-step explanation:

Simplify the expressions

2 {}^{3}  - 2 {}^{1}  = 2 {}^{3}  - 2 = 8 - 2 = 6

2 + 3 = 5

{3}^{2}  = 9

So the expressions from least to greatest is

2 {}^{1}  + 3 {}^{1}  < 2 {}^{3}  - 2 {}^{1}  < 3 {}^{2}

Which is the approximate solution for the system of equations x+5y=10 and 3x+y=1?
Nina [5.8K]
<h3>Answer: The approximate solution is (-0.36, 2.08).</h3>

Step-by-step explanation:

Given system of equations :

x+5y=10 and 3x+y=1.

Let us solve the system of equation by substitution.

Solving second equation 3x+y=1 for y first.

3x+y=1.

Subtracting 3x from both sides, we get

3x-3x+y=1-3x

y = 1-3x.

Substituting y=1-3x in first equation x+5y=10, we get

x+ 5(1-3x) = 10.

x + 5 -15x =10

-14x +5 = 10.

Subtracting 5 from both sides, we get

-14x +5-5 = 10-5

-14x =5

Dividing by -14 on both sides, we get

-14x/-14=5/-14

x= -0.36.

Plugging x=-0.36 in second equation y=1-3x, we get

y = 1-3(-0.36) = 1+1.08 = 2.08.

<h3>Therefore, approximate solution is (-0.36, 2.08).</h3>

A ramp 12 feet long is leaning against a raised platform which is 5 feet above the ground. What is the distance from the ramp's
anygoal [31]

Answer:

The distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.

Step-by-step explanation:

As

  • A ramp 12 feet long is leaning against a raised platform which is 5 feet above the ground.

And

  • We have to determine the distance from the ramp's contact point with the ground and the base of the platform.

Since we are looking for the side of 'b' right triangle.

Please check the attached figure.

So using the Pythagorean formula:

Fora right angled triangle with sides a, and b the hypotenuse c is defined as

c^2=a^2+b^2

b=\sqrt{c^2-a^2}

  • a=5
  • c=12
  • b=?

b=\sqrt{12^2-5^2}

b=\sqrt{119}

b=10.90  feet

Therefore, the distance from the ramp's contact point with the ground and the base of the platform is 10.90 feet.
