Answer:

  8/12 yard or 2/3 yard

Step-by-step explanation:

The sum of the two lengths is ...

  5/12 yd + 3/12 yd = (5+3)/12 yd = 8/12 yd

This fraction can be reduced by removing a factor of 4 from numerator and denominator.

  8/12 yd = 2/3 yd

If the arm portions are end-to-end, the total length is 2/3 yard.

Find (-3/7) divided (-1 1/14)
Andrews [41]

Answer:

2/5

Step-by-step explanation:

first, we convert the mixed fractions to improper fractions,

-1\frac{1}{14}=\frac{15}{14}

so then we find what -\frac{3}{7}\div-\frac{15}{14}

-\frac{3}{7}\div-\frac{15}{14} = -\frac{3}{7} * -\frac{14}{15}

and that equals \frac{3*14}{7*15} , which equals \frac{42}{105}. We can simplify that to 2/5

Domain and range of the inequality y<√x+3 +1
Margaret [11]

The domain of the given inequality is y>1.

<h3>What is Inequality?</h3>

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Here, given inequality:

              y < \sqrt{x+3}+1

Related equation:

             y = \sqrt{x+3}+1

The equation defined as,

    x+3 > 0

    x > -3

In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.

So, the domain of the given inequality is x>-3.

We know that,

    \sqrt{x+3} \geq 0

adding 1 on both sides, we get

  \sqrt{x+3} + 1 \geq  1

      y ≥ 1

The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.

Thus, the domain of the given inequality is y>1.

Which of following equations is of a parabola with a vertex at (3,0)? Y=(x-3)^2, y=x+3^2, y=x^2-3, y=x^2+3
e-lub [12.9K]

Answer:

y = (x - 3)²

Step-by-step explanation:

The vertex of the general equation of the parabola of the form:

y = (x - h)² + k

is at (h, k)

We are given that the vertex is at the point (3, 0)

This means, h = 3 and k = 0

Using these values in the first equation, we get:

y = (x - 3)² + 0

y = (x - 3)²

Therefore, 1st option gives the parabola with vertex at (3, 0)
