The shadow cast by a lampshade has a boundary in the shape of a hyperbola defined by the equation StartFraction (y minus 3) squared Over 2 EndFraction minus StartFraction x squared Over 1 EndFraction = 1. What could the center of the hyperbola represent?
the location of the light bulb
the bottom of the lampshade
the top of the lampshade
a vertex of the shadow
Answers
Answer:
A THE LOCATION OF THE LIGHT BULB
I got this right on the assignment
Step-by-step explanation:
The centre of the hyperbola represent will represent the location of the light bulb.
What is the centre of a hyperbola?The centre of a hyperbola is the midpoint of the line segment joining its foci. The transverse axis is the line segment that contains the centre of the hyperbola and whose endpoints are the two vertices of the hyperbola.
As we know that the centre of a hyperbola is the midpoint of the line segment joining its foci. Now, if we plot the hyperbola with equation
[tex]\dfrac{(y-3)^2}{2}-\dfrac{x^2}{1}=1[/tex]
The hyperbola will look like the one given in the below image, further if draw two lines to know the centre of the hyperbola, we will find that the centre of the hyperbola will lie at coordinate (0,3).
Further, the centre of the hyperbola represents the light bulb while the hyperbolas will represent the shadow cast by the lampshade.
Hence, the centre of the hyperbola represent will represent the location of the light bulb.

PLEASE HELP OR ELSE MOM WILL BE REALLY MAD!!!!! Two trains, one going from Boston to New York and the other going from New York to Boston, started their trips at exactly same time. Speed of the first train was 10 mph less than twice the speed of the second train.How far from Boston station to have the Met in two hours, if the total distance between cities along the railroad is 220 miles?
Answers
Answer:
140 mile
Step-by-step explanation:
[tex]d_{1} +d_{2} =220\\2(2x-10+x)=220\\x=40\\d_{1}=2*(2*40-10)=140mile[/tex]
While x is the speed of the second train.
The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.
SpeedSpeed is the ratio of total distance to total time taken. It is given by:
Speed = distance / time
Let a represent the speed of the first train. In two hours:
a = d₁/2
d₁ = 2a
a + 10 = d₂/2
d₂ = 2a + 20
d₁ + d₂ = 220
2a + 2a + 20 = 220
4a = 200
a = 50 miles per hour
The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.

The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

Ben and Jerry are driving to Chicago and it takes 270 miles to get there. They
have already traveled 42 miles and are driving 75 mi/h. Write a function that
models the distance they drive as a function of time.
Answers
Answer:
d= 75*t
Step-by-step explanation:
Given data
We are given that the total distance = 270 miles
And that they have already traveled 42 miles
speed= 75mi/h
The remaining distance of the journey is = 270-42
= 228 miles
We know that
speed= distance/time
distance= speed*time
also
d= 75*t
Hence, we can estimate the distance they have traveled for any number of time t

x + y = 650 and 60x + 80y = 43000
y = 650 - x 60x + 80(650 - x) = 43000
60x + 52000 - 80x = 43000
