The line
<span>The sum of twice x and 3 times y is less than 6
is the same as
2x + 3y < 6
which can be transformed into
y < -2x/3 + 2

and
</span><span>y must be greater than 1 less than twice the x
is
y > 2x - 1

The solution is represented by the first figure.</span>

Let f ( ) sin(arctan ) x x = . What is the range of f ?
nikklg [1K]
<span>So you have composed two functions,
</span><span>h(x)=sin(x) and g(x)=arctan(x)</span>
<span>→f=h∘g</span><span>
meaning
</span><span>f(x)=h(g(x))</span>
<span>g:R→<span>[<span>−1;1</span>]</span></span>
<span>h:R→[−<span>π2</span>;<span>π2</span>]</span><span>
And since
</span><span>[−1;1]∈R→f is defined ∀x∈R</span><span>

And since arctan(x) is strictly increasing and continuous in [-1;1] ,
</span><span>h(g(]−∞;∞[))=h([−1;1])=[arctan(−1);arctan(1)]</span><span>
Meaning
</span><span>f:R→[arctan(−1);arctan(1)]=[−<span>π4</span>;<span>π4</span>]</span><span>
so there's your domain</span>

Answer:

3 \: s

Step-by-step explanation:

y =  - 16 {x}^{2}  + 32x + 48 \\ 0 =  \frac{ - 16 {x}^{2} + 32x + 48 }{ - 16}  \\0  =  {x}^{2}   - 2x - 3 \\   0= {x}^{2}  - 3x + x - 3 \\  0= x(x - 3)  + 1(x - 3) \\0  = (x + 1)(x - 3) \\  \\ x + 1 = 0  \\ x =  - 1 \\ x - 3 = 0 \\ x = 3

Hope this helps you.
