The focus is a fixed point inside the parabola. The line of symmetry intersects the focus and directrix. The line of symmetry and the directrix are perpendicular. The parabola intersects the directrix.

Answers

Answer 1

Answer:

A parabola is the set of all points equidistant from the directrix and focus.

The line of symmetry intersects the focus and directrix

The line of symmetry and the directrix are perpendicular

Step-by-step explanation:

A parabola is the set of all points in a plane that are equidistant from a fixed point (focus) and a line (directrix).

The fixed line of a parabola is known as the directrix of the parabola.

The line of symmetry is a line that passes through the focus and is perpendicular to the directrix. The line of symmetry divides the parabola.

The directrix of a parabola does not intersect touch the parabola

Answer:

3/2

Step-by-step explanation:

Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7

Which of the following is equivalent to 5x-6y=20?

A y=5/6x
B y=5/6x-10/3
C y=6/5x+4
D y=-5/6x​

Answers

Answer:

y =  [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]

Step-by-step explanation:

Given expression:

               5x  - 6y = 20

To solve this problem, we make y the subject of the expression:

     Solution

              5x  - 6y = 20

      Add -5x to both sides of the expression;

              -5x + 5x - 6y = 20 + (-5x)

                             -6y  = 20 - 5x

     Now, multiply both sides by [tex]-\frac{1}{6}[/tex] ;

              [tex]-\frac{1}{6}[/tex]  x (-6y) =  [tex]-\frac{1}{6}[/tex] (20 - 5x )

                         y  = [tex]-\frac{20}{6}[/tex] + [tex]\frac{5}{6}[/tex]x

                         y =  [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]

Waterco is filling barrels with waste water at the rate of 8 quarts per hour. The recycling facility picks up 150 barrels on each trip, and each barrel holds 15 quarts of wastewater. How many days are between each pick up? Show your work to receive full credit. Round answer to the tenths place 

Answers

Answer:

11.7 days

Step-by-step explanation:

Given that:

Filling rate = 8 quarts per hour

150 barrels picked up per trip

One barrel = 15 quarts of waste water

Barrel picked up per trip = 150 barrels

Number of quarts per barrel = 15 quarts

Total quantity of waste water = (150 * 15) = 2250 quarts

Filling rate = 8 quarts per hour

Time taken = quantity / rate

Time taken in days = 2250 quarts /(8*24) = 11.72

11.7 days

Farmer Jane has many hens that have laid many eggs. Before the eggs hatch, Jane wants to
count how many eggs are blue, how many are brown, and how many are white.
Jane counts that, of all the eggs, 6 are blue and 25% are brown.
If 10% of the eggs are blue, how many of the eggs are white?
a) 15
b) 21
c) 39
d) 65

Answers

Answer:

The correct option is;

c) 39

Step-by-step explanation:

The given information are;

The number of eggs that are blue = 6

The percentage of eggs that are brown = 25%

The percentage of eggs that are blue = 10%

Let the number of eggs Jane has = X

Therefore;

10% of X = 10/100 × X = 6

X = 6 × 100/10 = 60

The number of eggs Jane has = X = 60

The percentage of the eggs that are white eggs = 100 - (The percentage of eggs that are brown + The percentage of eggs that are blue)

The percentage of the eggs that are white eggs = 100 - (10 + 25) = 65%

The percentage of the eggs that are white eggs = 65%

∴ The number of  eggs that are white = 65% of X = 65/100 × X= 65/100× 60 = 39 eggs

The number of  eggs that are white = 39 eggs.

Jacob buys 6 game tickets and 3 ride tickets at a carnival for $39. Emily buys 2 game tickets and 2 ride tickets for $18. Find the cost of a game ticket and the cost of a ride ticket at the carnival. Set up and solve a system of equations.
Your answer:

Answers

Answer:

Cost of ride ticket = $5

Cost of game ticket = $4

Step-by-step explanation:

Given that:

Let ;

game ticket = g

Ride ticket = r

Jacob :

6g + 3r = 39 - - - (1)

Emily :

2g + 2r = 18 - - - - (2)

Divide (2) b y 2

g + r = 9 - - - - (3)

From (3)

g = 9 - r

Substitute ; g = 9 - r into (1)

6(9 - r) + 3r = 39

54 - 6r + 3r = 39

54 - 3r = 39

-3r = 39 - 54

-3r = - 15

r = 5

Put r = 5 in (g = 9 - r)

g = 9 - 5

g = 4

Hence,

Cost of ride ticket = $5

Cost of game ticket = $4
