Answer:

The shop originally spent $56

Step-by-step explanation:

Suppose, the shop spent  dollars originally.

Given that, the total cost is 150% of what the shop spent originally. So, the total cost will be:   dollars.

The shop sells you a bicycle for $63 and a helmet for $21. So, the total cost

Thus, the equation will be.........

So, the shop spent $56 originally.

Answer: Initial cost = $56

Profit = $28

Step-by-step explanation:

A bicycle costs $63

A helmet cost $21

The total cost is 150% of what the sho spent originally for these tiems:

The total cost is C = $63 + $21 = $84

and we know that this cost is the 150% of the initial cost, K:

C = (150%/100%)*K = 1.5*K

So the initial cost is:

K = C/1.5 = $84/1.5 = $56

The profit will be the difference between the two costs:

P = C - K = $84 - $56 = $28

So the shop earns $28 by selling the bicycle and helmet

PSYCHO15rus [73]

The resulting composite function (f∘f)(x) is x⁴+2x²+2

When a function is written inside another function, it is known as a composite function

Given the function f(x)=x²+1,

(f∘f)(x) = f(f(x))

f(f(x)) = f(x²+1)

This means we will need to replace x with x²+1 in f(x) as shown:

f(x²+1) = (x²+1)²+1

Expand

f(x²+1) = x⁴+2x²+1+1

f(x²+1) =  x⁴+2x²+2

Hence the resulting composite function (f∘f)(x) is x⁴+2x²+2

KengaRu [80]

Complete question :

la distancia entre la tierra y la luna es de 384 392 km. Los astronautas de la Apolo XL salieron el 16 de julio de 1969 desde el Centro Espacial Kennedy y al alcanzaron la orbita el 19 de julio de 1969. Suponiendo que cada dia recorrieron la misma cantidad de kilometros cuantos kilometros recorrieron por dia

Responder:

128130,66 kilometros

Explicación paso a paso:

Dado que:

Distancia entre la tierra y la luna = 384,392 km

Tiempo empleado = (19 de julio - 16 de julio) mismo año = 3 días

Velocidad = distancia / tiempo

El tiempo empleado es (3 * 24) = 72 horas

Por lo tanto,

velocidad = 384,392 / 72

= 5338,7777 kilómetros por hora

Dado que se supone que la distancia recorrida diariamente es la misma m:

El número de kilómetros recorridos por día:

5338,7777 kilómetros por hora * 24

= 128130,66 kilometros
