Answer:280
Step-by-step explanation:
so 140 is twice amount of money on hotels so you multiply 140 by 2 .
The foci of the hyperbola represented by (0, –6) and (0, 6). Then the correct option is B.
<h3>What is a hyperbola?</h3>
The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
The equation of the parabola is given below.
5y² – 4x² – 80 = 0
Then the equation can be written as
y² / 4 – x² / 5 – 4 = 0
y² / 16 – x² / 20 = 1
Then the value of eccentricity will be
a² = 16 and b² = 20
Then we have
e = √[1 + (b² / a²)]
e = √[1 + (20 / 16)]
e = 1.5
Then the focus of the parabola will be
⇒ (0, ±ae)
⇒ (0, ± 4 x 1.5)
⇒ (0, ±6)
⇒ (0, –6) and (0, 6)
Then the correct option is B.

Answer:
x = -5/6
Step-by-step explanation:
Since it is on the unit circle
x^2 + ( -sqrt(11)/6)^2 = 1 ^2 (pythagorean theorem)
x^2 = 1 - 11/36
x^2 = 25 /36
x = +-5/6 since x is in Q III it is the negative
Answer:
6n = 1.50
and
13n = 3.12
Step-by-step explanation:
Here in this question, we are interested in writing equations that relate the number of ears of corn sold and the cost.
For Al’s produce stand, let the price per corn sold be n
Thus;
6 * n = 1.50
6n = $1.50 •••••••(i)
For the second;
let the price per corn sold be n;
13 * n = $3.12
-> 13n = 3.12 •••••••••(ii)
