Let g(x, y) = cos(x + 5y). (a) Evaluate g(10, −2). g(10, −2) = (b) Find the domain of g. −1 ≤ x ≤ 1, − 1 5 ≤ y ≤ 1 5 −5 ≤ x ≤ 5,
RoseWind [281]

Answer:

since Cos(z) is a function defined for all z\in \mathbb{R}, then there is not restriction for x+5y, thus, the domain of g(x,y) is \mathbb{R}^2 and in interval notation is (-\infty,\infty)\times(-\infty,\infty)

Since Cos(x+5y)\in\mathbb{R} then the range of g(x,y) is the interval [-1,1].

What is the volume of this sphere?
Angelina_Jolie [31]
<h3>given:</h3>

radius= 4 m

<h3>to find:</h3>

the volume of the given sphere.

<h3>solution:</h3>

v =  \frac{4}{3} \pi {r}^{3}

v =  \frac{4}{3}  \times 3.14 \times  {4}^{3}

v = 267.9466667 \:  {m}^{3}

v = 267.95 \:  {m}^{3}

<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>sphere</u><u> </u><u>is</u><u> </u><u>267.95</u><u> </u><u>cubic</u><u> </u><u>meters</u><u>.</u>
