Answer:

The rate of the slower cyclist is

22\frac{4}{5}km/h

and that of the faster cyclist is

27 \frac{4}{5}km/h

Step-by-step explanation:

We let x be the rate of the slower cyclist

rate \times time = distance

From the question, the distance between the two towns is 253 and the time taken for the two cyclist to meet is 5 hours

so we can write the equation

5x + 5(x + 5) = 253

We simplify to get the value for x

\implies5x + 5x  + 25 = 253

\implies10x = 253 - 25

\implies10x = 228

\implies x =22 \frac{4}{5}

Hence the rate of the slower cyclist is

22 \frac{4}{5} km/h

and that of the rate faster cyclist is

27 \frac{4}{5}km/h

Solve the following system algerbraically: y=-3(x-2) squared+4 y=-6x+16
pishuonlain [190]

y =  - 3(x - 2) ^{2}  + 4
y =  - 6x + 16
distribute the -3 and the square into the first equation
y =  - 3x ^{2}  + 12x - 8
y =  - 6x + 16
multiply the second equation by 2
y =  - 3x ^{2}  + 12x - 8
y =  - 12x + 32
add the equations together
y =  - 3x ^{2}  + 24
factor out -3
y =  - 3(x ^{2}  - 8)
factor inside parenthesis
y =  - 3(x +  \sqrt{8} )( x -  \sqrt{8})
refine
y =  - 3(x + 2 \sqrt{2} )(x - 2  \sqrt{2} )

Answer:

f(f(5)) = 11

Step-by-step explanation:

f(f(5)) \\ from \: the \: table \: f(5) = 9 \\ so \: f(f(5)) = f(9) \\ also \: from \: the \: table  f(9) = 11 \\ so \: f(f(5)) = 11

Find the center, vertices, and foci for the ellipse 25x^2+64y^2=1600
Ronch [10]

Answer:

Step-by-step explanation:

Answer:

Data

Equation               25x² + 64y² = 1600

Process

1.- Divide all the equation by 1600

                            25x²/1600 + 64y²/ 1600 = 1600/1600

-Simplify

                             x²/64 + y²/ 25 = 1

2.- Equation of a horizontal ellipse

                            

3.- Find a, b and c

   a² = 64             a = 8

   b² = 25             b = 5

-Calculate c with the Pythagorean theorem

                  a² = b² + c²

-Solve for c

                  c² = a² - b²

-Substitution

                  c² = 8² - 5²

-Simplification

                 c² = 64 - 25

                 c² = 39

-Result

                 c = √13

4.- Find the center

         C = (0, 0)

5.- Find the vertices

         V1 = (-8, 0)     V2 = (8, 0)

6.- Find the foci

         F1 = (-√13, 0)   F2 = (√13, 0)
