18.6 (Second questions)

According to the thyoreme of Pythagor, the side of a traingle squared plus the other side of the triangle squared is equal to the hypothenuse squared. The hypothenuse is the longer side of a triangle and in this case our diagonal. Then we find the square root of 15(2) + 11(2). It is 18.60349683.

That long number is equal to 18.6

Answer:

Step-by-step explanation:

w^2 + l^2 = d^2

if length = 15 and width =11

(11)^2 + (15)^2 = d^2

346 = d^2

$\sqrt{346}$ = d

Answer:

0,-12

Step-by-step explanation:

you would put the two x quardinates and subtract them and then do the same for the y quardinates so

5-5 =0

-9-3=-12 so ur answer is 0, -12

Write an equation for a parabola in which the set of all points in the plane are equidistant from the focus and line F(-6,0); x=

Bogdan [553]

Step-by-step explanation:

Since we have a vertical directrix, the equation of the parabola is

$(y - k) {}^{2} = 4p(x - h)$

Where p is the distance from the vertex to the directrix.

or the distance from the vertex to the focus.

Since we have a sideways parabola, let use the point for the directrix is (-6,0). So let find the midpoint of (-6,0) and (6,0). That would be our vertex.

$\frac{ - 6 + 6)}{2} = 0$

$\frac{0 + 0}{2} = 0$

So our vertex is (0,0).

So our equation become

${y}^{2} = 4px$

The distance from the focus and directrix is 6.

So p=6.

${y}^{2} = 24x$

So p is 6.

Since p is 6,

$\frac{ {y}^{2} }{24} = x$

Please help me. 704 geometry honors activity.

hoa [83]

Answer:

See IN set by step

Step-by-step explanation:

1.We choose a fish pond of radius 3 centered at (x, y) = (0, 3). The equation of the circle is ...

(x -0)^2 +(y -3)^2 = 3^2

x^2 +(y -3)^2 = 9

At this location it is easy to draw a radius along the y-axis to a point of tangency at the origin. That radius is a vertical line, so the tangent line will be perpendicular--a horizontal line.

A horizontal line through the origin has equation y = 0, and its point of intersection with this circle is (0, 0).

Comment on the question

You haven't elaborated on what the lesson discussed, so we have no idea what steps you want included.

I could not answer 2 and 3 but maybe if i get it i will edit this paper and add it in.

Can you please help me with A and B

I read:
Farm Maid Yogurt : 6 g of fat in 13 cups
Dairy Delight Yogurt: 5 g of fat in 11 cups.

(This is what I read, which does not represent realistic numbers, likely decimals are missing).

(a) Farm Maid Yogurt
6 g/13 cups = 10 g/x cups
Cross multiply: 6x = 130 => x=130/6=21.67 cups.

(b)
Farm maid : 6 g/13 cups, 6/13 in 13/13 cups => 0.4615 g/cup
Dairy Delight : 5 g / 11 cups, 5/11 in 11/11 cups => 0.4545 g/cup
=> Dairy Delight Yogurt has slightly less fat.

(c) 9 cups of Dairy Delight
5 g / 11 cups = x g / 9 cups
Cross multiply
11x=5*9 g => x=5*9/11 g = 4.09 g

(d) 3 cups of Dairy Delight & 5 cups of Farm Maid.
5 g/ 11 cups = x g / 3 cups
Cross multiply
x=5*3/11 = 1.3636 g

5 cups of Farm Maid
6 g / 13 cups = y g / 5 cups
Cross multiply
y=6*5/13=2.3077 g

Total fat consumed = 1.3636+2.3077 g = 3.6713 = 3.671 g (to the nearest thousandth gram).
