liubo4ka [24]3 years ago
5 0

Answer:

\boxed{ \boxed{ \sf \: x \: intercept : 8  \atop  \sf \: y \: intercept : 2}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • linear equation
  • PEMDAS
<h3>given:</h3>
  • \tt y =   - \frac{1}{4}  x+ 2
<h3>to find:</h3>
  • x and y intercept
<h3>tips and formulas:</h3>
  • to find x and y intercept we have to substitute x and y to 0
<h3>let's solve:</h3>

let's substitute x to 0 to find y intercept

  • y=-¼(0)+2
  • y=2

therefore y intercept is 0

let's substitute y to 0 to find x intercept

  • 0=(-¼)x+2
  • (-¼)x=-2
  • x=-2×-4
  • x=8

therefore

<h3>x intercept is 8</h3>

and

<h3>y intercept is 2</h3>

also see the graph

explanation of the graph

you can clearly see that the red line crosses x and y axis to (8,0) and (0,2) respectively

therefore

x intercept is 8

and

y intercept is 2

. A bridge over a river is built in the shape of a parabolic arch. The bridge has a span of 100 feet. The height of the arch is
katen-ka-za [31]

Answer:

The height of the arch at its center is 250/9 or about 27.78 feet.

Step-by-step explanation:

We can write an equation to model the parabolic arch.

Let the left-most point of the arch be the origin (0, 0).

Since the bridge has a span of 100 feet, the right-most point must be (0, 100).

We can use the factored form of a quadratic:

y=a(x-p)(x-q)

Where <em>p</em> and <em>q</em> are the <em>x-</em>intercepts.

Our <em>x-</em>intercepts are <em>x </em>= 0 and <em>x </em>= 100. Hence:

y=ax(x-100)

At a point 40 feet from the center, the height of the arch is 10 feet.

The center is <em>x</em> = 50. So, a point 40 feet from the center can be either <em>x</em> = 10 or <em>x</em> = 90.

So, for instance, when <em>x</em> = 10, <em>y</em> = 10. Substitute and solve for <em>a: </em>

<em />10=10a(10-100)<em />

So:

\displaystyle a=-\frac{1}{90}

The same value will result if we let <em>x</em> = 90 and <em>y</em> = 10.

Hence, our equation is:

\displaystyle y=-\frac{1}{90}x(x-100)

The height of the arch at its center will be when <em>x</em> = 50. Hence:

y(50)=\displaystyle -\frac{1}{90}(50)((50)-100)=\frac{250}{9}\approx 27.78\text{ feet}
