Rotate by angle α = 90°, around a center point (0; 0)
Answer:
y = 5 sin (2x) + 4
Step-by-step explanation:
this is sines function,
the amplitude is [9 - (-1)]/2 = 10/2 = 5
the period is 2πx/π = 2x
the x-axis of actual function is at y = 4
so, the function is :
y = 5 sin (2x) + 4
Answer:
20
Step-by-step explanation:
- x+20%=24
- x+x*20/100=24
- x+0.2x=24
- 1.2x=24
- x=24/1.2
- x=20
<span>Podemos resolver as equações da seguinte forma:
11) -2,6 x 10³ ----> iremos andar três casas para direita.
X = -2600 12) 5,824 x </span>
![10^{-2}](https://tex.z-dn.net/?f=%2010%5E%7B-2%7D%20)
<span> ---> iremos andar duas casas para esquerda.
X = 0,05824 13) - 5,408 ---> iremos adicionar o </span>
![10^{0}](https://tex.z-dn.net/?f=%2010%5E%7B0%7D%20)
<span>
x = </span>
- 5,408 x ![10^{0}](https://tex.z-dn.net/?f=%2010%5E%7B0%7D%20)

14) 0,00907 ----> iremos adicionar o </span>
x = 9,07 x
