8. Uma indústria têxtil vende diariamente 800 m2 de certo tipo de brim ao preço de R$10,00 por metro quadrado. Uma pesquisa de mercado revelou que, para cada desconto de R$0,04 por metro quadrado desse brim, haveria um acréscimo diário de 5 m2 nas vendas. Levando em consideração essa pesquisa, o departamento de vendas da indústria estabeleceu o preço por metro quadrado desse brim para que a receita diária arrecadada com a venda fosse máxima. a) Qual foi o preço estabelecido por metro quadrado desse brim? b) Qual será a receita diária apurada com a venda desse brim para o preço estabelecido?

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

about the problem:

srry i'm not done ! i'll

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
