Answer:

$\frac{7}{5}$

Step-by-step explanation:

To divide fractions, flip, then multiply:

$\frac{13}{25} \div \frac{13}{35} = \frac{13}{25} \times \frac{35}{13}$

To multiply fractions, divide the product of the numerators by the product of the denominators.

$\frac{13}{25} \times \frac{35}{13} = \frac{13 \times 35}{25 \times 13} = \frac{455}{325} = \frac{7}{5}$

The sides of a rhombus are equal length, so you have

... 5x + 20 = 6x + 10

... 10 = x . . . . . . . . subtract 5x+10

Then the side lengths are

... 5·10 +10 = 70

What does "opposite semi-planes of segment" mean?

alexdok [17]

Answer:

opposite half-planes – the two half-planes that are separated by a particular line of the plane. If points Y and Z are in opposite half-planes, the segment joining them must intersect the edge.

A bridge is built in the shape of a parabolic arch. The bridge arch has a span of 166 feet and a maximum height of 40 feet. Find

scoray [572]

Answer:

38.27775 feet

Step-by-step explanation:

The bridge has been shown in the figure.

Let the highest point of the parabolic bridge (i.e. vertex of the parabola) be at the origin, $O(0,0)$ in the cartesian coordinate system.

As the bridge have the shape of an inverted parabola, so the standard equation, which describes the shape of the bridge is

$x^2=4ay\;\cdots(i)$

where $a$ is an arbitrary constant (distance between focus and vertex of the parabola).

The span of the bridge = 166 feet and

Maximum height of the bridge= 40 feet.

The coordinate where the bridge meets the base is $A(83, -40)$ and $B(-83, -40).$

There is only one constant in the equation of the parabola, so, use either of one point to find the value of $a$ .

Putting $A(83,-40)$ in the equation (i) we have

$83^2=4a(-40)$

$\Rightarrow a=-43.05625$

So, on putting the value of $a$ in the equation (i), the equation of bridge is

$x^2=-172.225y$

From the figure, the distance from the center is measured along the x-axis, x coordinate at the distance of 10 feet is, $x=\pm 10$ feet, put this value in equation (i) to get the value of y.
