Pedro fez a seguinte crítica: "O gráfico traz números absolutos, indicando que São Paulo tem muito mais mortes no trânsito que N

ova York. Porém, seria necessário considerar o tamanho da população, para ter certeza de que a situação é pior em São Paulo. Por exemplo, São Paulo tinha cerca de 12 milhões de habitantes à época e, portanto, esse total de 1152 mortes representa uma taxa de 9,6 mortes a cada cem mil habitantes. Qual seria essa taxa no caso de Nova York?" Para fazer a verificação sugerida por Pedro, precisamos considerar que Nova York tinha cerca de 8,3 milhões de habitantes à época. Então, concluiremos que a taxa de mortes a cada cem mil habitantes nessa cidade era, aproximadamente,

7) (12 + 6)/(2 +4)
(18)/(6) = 3

8) (42 - 24)/6
(18)/6 = 3

9) (9 + 16) - (2 x 4)
25 - 8 = 17

10) 60 - (3 + 2) x 5
60 - 5 x 5
60 - 25 = 35

How can you write 200,000 using a whole number and a power of 10
jeka94

Hey!

-----------------------------------

Question Explanation:

In other words you can write 200,00 using a whole number and a power 10 using scientific notation!

In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.

-----------------------------------

Solution:

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

-----------------------------------

Answer:

2 x 10^5

-----------------------------------

Answer:

Step-by-step explanation:

a. Since the parabola is compressed by a factor of 1/3 we can state:

  • a parabola is written this way : y=(x-h)²+k
  • h stands for the translation to the left ⇒ 2*3=6
  • k for the units down  ⇒4*3=12

So the equation is : y=(x-6)²+12

b.Here the parabola is stretched by a factor of 2 so we must multiply by 1/2

  • We khow that a parabola is written this way : y=(x-h)²+k
  • (h,k) are the coordinates of the vertex
  • the maximum value is  7*0.5=3.5
  • we khow tha the derivative of a quadratic function is null in the maximum value
  • so let's derivate (x-h)²+k= x²+h²-2xh+k
  • f'(x)= 2x-2h    h is 1 since the axe of simmetry is x=1
  • f'(x)=2x-2 ⇒2x-2=0⇒ x= 1
  • Now we khow that 1 is the point where the derivative is null
  • f(1)=3.5
  • 3.5=(x-1)²+k
  • 3.5= (1-1)²+k⇒ k=3.5

So the equation is : y=(x-1)²+3.5

7.

the maximum height is where the derivative equals 0

  • h= -5.25(t-4)²+86
  • h= -5.25(t²-8t+16)+86
  • h=-5.25t²+42t-84+86
  • h=-5.25t²+42t+2

Let's derivate it :

  • f(x)= -10.5t+42
  • -10.5t+42=0
  • 42=10.5t
  • t= 42/10.5=4

When the height was at max t=4s

  • h(max)= -5.25(4-4)²+86 = 86 m

h was 86m
