3%= .03
6/8 * .03 = 0.0225
or if you want it in percent form it'd be "2.25%"

Steps for x squared plus y squared minus 8x + 12 y + 27 equals 0

Sphinxa [80]

X²+y²-8x+12y+27=0
x²+y²-8x+12y=-27
x²-8x +y²+12y = -27
x²-8x+16 + y+12y+36 = -27+16+36=25
(x-4)² + (y+6)² = 25

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 32,800. If the population growth follow

grigory [225]

The rate is (32,800 - 18,000) = 14,800 per 5 years
<span>therefore : </span>
<span>in 2015 = 2010 + 5 years </span>
<span>the pop. will be : </span>
<span>32,800 + 14,800 = 47,600

Hope this helped☻</span>

12. F(x) = 4x squared

Ymorist [56]

Answer:

y-intercept: $y=0$

axis of symmetry: $x=0$

vertex: $(0,0)$

Step-by-step explanation:

To find the y-intercept, set x = 0 and solve for y.

I am assuming f(x) = y

$y=4x^2$

$y=4(0)^2$

$y=0$

The y-intercept of the equation is y = 0.

Now, for the axis of symmetry, you need the equation $x=\frac{-b}{2a}$

In an equation.. $y=ax^2+bx+c$

In this case, there is only an a, so plug in the values into the equation.

$x=\frac{0}{2(4)}$

$x=0$

The axis of symmetry is x = 0.

To find the vertex, change the format of the equation from standard form to vertex form.

Vertex form: $y=a(x-h)^2+k$

The vertex is $(h,k)$

$y=4x^2 = 4(x+0)^2+0$

$(h,k)=(0,0)$

The vertex in this case is (0,0).

Graphing makes things a lot easier. If you can graph it, all you have to do is look at the graph and the answers are all there!

In 2003, the owl population P in a park was measured to be 340. By 2007, the population was measured again to be 285. The popula

Answer:

y = -13.75x + 340

120 owls in 2019

Step-by-step explanation:

To find the population in a future year, use the formula y=mx+b since it changes linearly.

So over 4 years the owl population changed from 285-340=-55. Divide by 4 and this is a yearly change of -13.75. This is m.

The y-intercept is the starting point known as b in the equation. Here it is 340.

So the equation is y=-13.75x+340.

In 2019, t=16 so y=-13.75(16)+340 = 120.
