Answer:

Step-by-step explanation:

permeter is solved by doing length+length+width+width so therefore you would do 13+13+5+5 which equals 36 as your answer

An amount of $15,000 is invested in a fund that has a return of

IrinaVladis [17]

Answer:

$12000 should be invested in a fund with a 4% return.

Step-by-step explanation:

Consider the provided information.

An amount of $15,000 is invested in a fund that has a return of 6%.

We need to calculate how much money is invested in a fund with a 4% return if the total return on both investments is $1380.

Let $x should be invested in a fund with a 4% return.

The above information can be written as:

$1380=15000\times 6\%+x\times 4\%$

$1380=15000\times \frac{6}{100}+x\times \frac{4}{100}$

$1380=150\times6+x\times 0.04$

$1380-900=0.04x\\480=0.04x\\x=12000$

Hence, $12000 should be invested in a fund with a 4% return.

Find the equation of the axis of symmetry of the following parabola algebraically.

mr Goodwill [35]

Answer:

the equation of the axis of symmetry is $x=8$

Step-by-step explanation:

Recall that the equation of the axis of symmetry for a parabola with vertical branches like this one, is an equation of a vertical line that passes through the very vertex of the parabola and divides it into its two symmetric branches. Such vertical line would have therefore an expression of the form: $x=constant$ , being that constant the very x-coordinate of the vertex.

So we use for that the fact that the x position of the vertex of a parabola of the general form: $y=ax^2+bx+c$ , is given by:

$x_{vertex}=\frac{-b}{2\,a}$

which in our case becomes:

$x_{vertex}=\frac{-b}{2\,a} \\x_{vertex}=\frac{48}{2\,(3)} \\x_{vertex}=\frac{48}{6} \\x_{vertex}=8$

Then, the equation of the axis of symmetry for this parabola is:

$x=8$
