Answer:

The answer to your question is:

side 1 = 22.5 cm

side 2 = 30 cm

side 3 = 37.5 cm

Step-by-step explanation:

ratio = 3:4:5

Perimeter = 90 cm

First we get the sum of the numbers of the proportions

3 + 4 + 5 = 12

now divide the perimeter by the number of parts (12)

90 / 12 = 7.5

Side 1 = 3(7.5) = 22.5 cm

Side 2 = 4(7.5) = 30 cm

Side 3 = 5(7.5) = 37.5 cm

Perimeter = 22.5 + 30 + 37.5 = 90 cm

The stream of water from a fountain follows a parabolic path. The stream reaches a maximum height of 7 feet, represented by a ve

First of all, I'm going to assume that we have a concave down parabola, because the stream of water is subjected to gravity.

If we need the vertex to be at $x=4$ , the equation will contain a $(x-4)^2$ term.

If we start with $y=-(x-4)^2$ we have a parabola, concave down, with vertex at $x=4$ and a maximum of 0.

So, if we add 7, we will translate the function vertically up 7 units, so that the new maximum will be $(4, 7)$

We have

$y = -(x-4)+7$

Now we only have to fix the fact that this parabola doesn't land at $(8,0)$ , because our parabola is too "narrow". We can work on that by multiplying the squared parenthesis by a certain coefficient: we want

$y = a(x-4)^2+7$

such that:

$a$
when we plug $x=8$ , we have $y=0$

Plugging these values gets us

$0 = a(8-4)^2+7 \iff 16a+7=0 \iff a = -\dfrac{7}{16}$

As you can see in the attached figure, the parabola we get satisfies all the requests.

Answer:

The rational numbers are $\frac{11}{3}, 6.25, 0.01045,\sqrt{\frac{16}{81}},0.\bar{42}$ and the irrational functions are $\sqrt{48},\sqrt{\frac{3}{16}}$ .

Step-by-step explanation:

A rational number can be expressed in the form of $\frac{p}{q}$ , where p and q are integers and q is not equal to 0. For example $2,3.5,\frac{2}{5},...$ .

An irrational function can not be expressed in the form of $\frac{p}{q}$ , where p and q are integers and q is not equal to 0. For example $\sqrt{2},\sqrt{3},\sqrt{5},...$ .
