Answer:

1/2

Step-by-step explanation:

slope = $\frac{rise}{run}$ = $\frac{2}{4}$ = $\frac{1}{2}$

$\frac{2}{4}$ = $\frac{3}{6}$ Same ratio. Both reduce to $\frac{1}{2}$

Solve for the value of y.<br> 60°<br> (8y-2)

rusak2 [61]

Since it's a right angle the sum of the two angles equals 90°
(8y-2)°+60°=90°
8y-2=90-60
8y-2=30
8y=30+2
8y=32
y=32/8
y=4

Answer:

181

Step-by-step explanation:

The tagged deer seem to represent about 17/110 of the population. Since there are 28 deer with tags, the population (p) is estimated to be ...

110/17 = p/28

p = 28(110/17) ≈ 181

There are about 181 deer in the woods.

The vertex of the parabola below is at the point (1,3), and the point (2,6) is

Inessa05 [86]

Answer:

B. y=3(x-1)2 + 3

Step-by-step explanation:

Given that

vertex of the parabola is at the point (1,3)

let's verify, if the option B is the correct equation of the parabola.

$y=3(x-1)^2 + 3\\ \\y=3(x^2+1-2x) + 3\\\\y=3x^2+3-6x + 3\\\\y=3x^2-6x + 6....Eq1$

comparing to standard equationof parabola (standard quadratic equation), we get

$a=3, b=-6 and c=6$

to find the vertex we use formula for x- coordinate as $x=-b/2a$

$x=-(-6)/2(3)\\\\x=6/6\\x=1$

to find y put x=1 in the Eq1, we get

$y=3(1)^2-6(1)+6\\\\y=3-6+6\\\\y=3$

vertex =(x,y) = (1, 3)

thus vertex of the parabola from the equation y=3(x-1)2 + 3 is (1,3), thus verified
