Uma loja de equipamentos eletrônicos anunciou um celular com duas opções de venda. Na primeira opção, o pagamento pode ser feito
Lena [83]

Responda:

Preço = $ 400

Explicação passo a passo:

Dado que:

Primeira opção :

Pagamento em 5 investimento igual

Segunda opçao :

Pagamento feito em 8 iguais. Investimento

O preço por parcela do primeiro investimento é 30 a mais do que cada um do segundo

Deixe o preço do telefone = p

Valor por prestação = x

Segunda parcela:

Preço = 8x

Primeiro :

Valor por parcela = x + 30

P = 5 (x + 30)

Preço = 5x + 150

Portanto, igualando as duas equações:

8x = 5x + 150

8x - 3x = 150

5x = 150

x = $ 50

Usando qualquer das equações de preço:

Preço = 8x

Preço = 8 * 50

Preço do telefone = $ 400

You need 3 sticks of butter for every 24 giant cookies you bake.
marta [7]

Answer:

Sticks of butter : 2

Number of cookies : 40

Step-by-step explanation:

<em>Given that :You need 3 sticks of butter for every 24 giant cookies you bake.</em>

<em>----------------------------------------------------------------------------------------------------------</em>

<em>Sticks of butter                    Number of cookies</em>

<em>  3                                           24</em>

<em>  x                                             16</em>

<em>5                                                 y</em>

<em>----------------------------------------------------------------------------------------------------------</em>

<em>Let the unknown be x and y..</em>

<em>Since you need 3 sticks of butter for every 24 giant cookies you back</em>

<em>Then 24/3 = 8</em>

<em>Since the number of cookies is 16 then 16/8 = 2</em>

<em>Thus x = 2</em>

<em>Next for y.</em>

<em>Since you need 3 sticks of butter for every 24 giant cookies you back</em>

<em>Then 5 * 8 = 40</em>

<em>Thus, y = 40</em>

<em>----------------------------------------------------------------------------------------------------------</em>

<em>Completed table below:</em>

<em>Sticks of butter                    Number of cookies</em>

<em>  3                                           24</em>

 2    <em>                                         16</em>

<em>5                                                 </em><em>40</em>

<em>----------------------------------------------------------------------------------------------------------</em>

For which of the following decreasing functions f does (f−1)′(10)=−1/8
Oduvanchick [21]

Recall the inverse function theorem: if f(x) has an inverse, and if f(a) = b and a = f⁻¹(b), then

f⁻¹(f(x)) = x   ⇒   (f⁻¹)'(f(x)) • f'(x) = 1   ⇒   (f⁻¹)'(f(x)) = 1/f'(x)

⇒   (f⁻¹)'(b) = 1/f'(a)

Let b = 10. Then pick the function f(x) such that f(a) = 10 and f'(a) = -8 for some number a.
