Fun!

The center of the hyperbola is the midpoint of its foci.  The distance between the foci is 43-9=34.   So they're 17 from the center.

We have coordinates

F1(0,17)

F2(0,-17)

Let's call the vertex of the hyperbola V.   We have

V(0,13)

This is a vertical hyperbola so the equation is of the form

\dfrac{y^2}{a^2}- \dfrac{x^2}{b^2}=1

The vertices for a vertical hyperbola like this are (0, a) and (0,-a)

So we have a=13

The distance c from the foci to the center is given by

c^2 = a^2+b^2

b^2 = c^2-a^2 = 17^2 - 13^2 = 120

That says our hyperbola's equation is

\dfrac{y^2}{169}- \dfrac{x^2}{120}=1

That's our answer.

A snack cart sells lemonade for $2 and hot dogs for $5. The vendor sold 86 items today for a total of $330. Which equation is tr
Alborosie

Let h be the number of lemonade sold. If the vendor sold 86 items today and h of them are lemonade, then the rest are hot dogs, so he sold 86-h hot dogs.

When you add the number of sold lemonade and hot dogs, then you get 86 items in total:

h+(86-h)=86.

This equation is exactly the same as equation

(86-h)+h=86.

Moreover,

1. if a snack cart sells lemonade for $2, then he gets $2h for h sold lemonade;

2.  if a snack cart sells hot dogs for $5, then he gets $5(86-h) for (86-h) sold hot dogs.

In total he gets $330, then

2h+5(86-h)=330.

Both these equations are true, but only first is among given options.

Answer: correct choice is B.

20. Solve for x when 18x = 2/3 Provide your answer as a fraction. please do not do website​
serious [3.7K]
18x/18 = 2/3 • 18
Flip reciprocal of 18 which is 1/18 so it would be 2/3 • 1/18 the 2 and 18 can be simplified when cross multiples so it would then be 1/3 • 1/9 which is x=1/27

Hi Lawrence!

---------------------------------------------------

We Know:

Powersports Plus: $30 an hour plus a non-refundable deposit of $50.

Sun & Surf: $20 an hour plus a non-refundable deposit of $80.

---------------------------------------------------

Equation:

x = per hour

y = total

Powersports: 30x + 50 = y

Sun and Surf: 20x + 80 = y

---------------------------------------------------

Solution: (Add the deposit then start adding hourly costs)

Powersports: 80, 110, 140

Sun and Surf: 100, 120, 140

---------------------------------------------------

Answer: After <u>3 hours</u> both companies will cost the same amount of money.

---------------------------------------------------

Hope This Helps :)

It would be f(t)= 25^t+1
If you plugged in '2' as 't',
25^2+1= 15, 625 which uses the second day of the bacteria.
