The vertices of a hyperbola are located at (−4, 1) and (4, 1). The foci of the same hyperbola are located at (−5, 1) and (5, 1).
topjm [15]

Answer:

x^2\ 16 - y^2/9 = 1

step-by-step explanation:

soooo the equation for a hyperbola that is horizontal is x^2/a^2 - y^2/b^2 = 1

a hyperbola should always equal one so dont forget that when writing your equation becuase it is easy to forget.

it helps to graph this so you can see it better

to find a it is the distance from the center to the vertices which is 4 so in the equation you will write 16 becuase it is a^2

then you need to find b. to get b you have to figure out that c is the distance from the center to the foci which is 5 and it is all related to the plythagorm theorum becuase it forms a right triangle. so you do c^2 - a^2 = b^2

you get 9 for b^2 because 25-16=9 and so you put that in the equation

A van travels 220 miles on 10 gallons of gas. Find how many gallons the van needs to travel 550 miles.
Anestetic [448]
The van will need 25 gallons of gas for it to travel 550 miles. This is calculated by dividing 10 gallons to 220 miles to get the miles per gallons, which in this case is 22 miles per gallon. Then we have to divide 550 miles by 22 miles per gallon to get the total gas consumption, which is 25 gallons.

Please give the actual reason clearly because everything i tried won’t give me the 2 needed marks
777dan777 [17]

Answer:

Step-by-step explanation:

Angle BAC = Angle ACD = 50 degrees, because they are alternate angles.

Angle ACB = 180 - (50 + 80) = 50 degrees, because angles in a triangle sum up to 180 degrees.

Since Angle BAC = Angle BCA, triangle ABC is isosceles.
