Answer:

48 m

Since area of the square having measure48m is in between the given range

Step-by-step explanation:

Area of square if side length is 46=2116 m²

Area of square if side length is 44=1936 m²

Area of square if side length is 48=2304 m²

Area of square if side length is 50 = 2500m²

Answer:

48!

Step-by-step explanation:

If the plot of land is a square, then the area can be found by multiplying one side by another. You'll have to multiply each number by itslef to see if the answer ranges anywhere between 2200 and 2400. 48 x 48 = 2304. 2304 is a number in between 2200 and 2400, and it is the only answer that is between 2200 and 2400. So, 48 can be one of the possible side lenghths of that square plot of land.

Part 2: Identify the vertex, focus, and directrix of each. Then sketch the graph.

Andre45 [30]

Answer: $\bold{1.\quad \text{Vertex}}:(-3,-6)\qquad \text{Focus}:\bigg(-3,-\dfrac{17}{4}\bigg)\qquad \text{Directrix}:y=-\dfrac{19}{4}$

2. Vertex: (-5, 4) Focus: (-6, 4) Directrix: x = -4

Step-by-step explanation:

The vertex form of a parabola is y = a(x - h)² + k or x = a(y - k)² + h

(h, k) is the vertex
p is the distance from the vertex to the focus
-p is the distance from the vertex to the directrix

$\bullet \quad a=\dfrac{1}{4p}$

1) y = (x + 3)² - 6 → a = 1 (h, k) = (-3, -6)

$a=\dfrac{1}{4p}\qquad \rightarrow \qquad 1=\dfrac{1}{4p} \qquad \rightarrow \qquad p=\dfrac{1}{4}\\\\\text{Focus = Vertex + p}\\\\.\qquad =\dfrac{-18}{4}+\dfrac{1}{4}\\\\.\qquad = -\dfrac{17}{4}\qquad \rightarrow \qquad \text{Focus}=\bigg(-3,-\dfrac{17}{4}\bigg)\\\\\\\text{Directrix: y = Vertex - p}\\\\.\qquad \quad y=\dfrac{-18}{4}-\dfrac{1}{4}\\\\.\qquad \quad y= -\dfrac{19}{4}$

****************************************************************************************

$2.\quad x=-\dfrac{1}{4}(y-4)^2-5\qquad \rightarrow \quad a=\dfrac{1}{4}\qquad (h, k)=(-5,4)$

$a=\dfrac{1}{4p}\qquad \rightarrow \qquad -\dfrac{1}{4}=\dfrac{1}{4p} \qquad \rightarrow \qquad p=-1\\\\\text{Focus = Vertex + p}\\\\.\qquad =-5+\ -1\\\\.\qquad = -6\qquad \rightarrow \qquad \text{Focus}=(-6,4)\\\\\\\text{Directrix: y = Vertex - p}\\\\.\qquad \quad y=-5+\ -1\\\\.\qquad \quad y= -4$

Answer:

1 / 4= 25%

Step-by-step explanation:

The percent of graduates in the sample had an income under $20,000

= Posibility of had an income under $20,000 / total posible outcomes

= 75 / 300

= 1 / 4= 25%

Hope this helped :3

What is the slope of the line? A. 0 B. 5 C. 11 D. Undefined

True [87]

Answer:

D. Undefined

Step-by-step explanation:

The slope is the ratio of rise to run. When the line is vertical, the run is zero, so calculating the slope involves division by zero. That makes the slope be undefined.

Need help like right now.

denpristay [2]

Let's go:

Big triangle:

12 + 3x - 6 = 3x + 6

10 + 8 = 18

$\frac{10}{18} = \frac{3x - 6}{3x + 6} \\\\ 10.(3x + 6) = 18.(3x - 6) \\\ 30x + 60 = 54x - 108 \\\ 54x - 30x = 60 + 108 \\\ 24x = 168 \\\ x = 7$

I hope I helped you.
