Bezzdna [24]

Answer:

$732

Step-by-step explanation:

Given

$y \to profit$

$x \to widgets$

$y = -x^2 + 64x - 292$

Required

The maximum profit

First, we calculate the maximum amount of widgets that can be sold using:

$x = -\frac{b}{2a}$

Where:

$a = -1; b = 64; x = -292$

So, we have:

$x = -\frac{64}{2 * -1}$

$x = -\frac{64}{-2}$

$x = -(-32)$

$x = 32$

The maximum profit is:

$y = -x^2 + 64x - 292$

$y = -(32)^2 + 64 * 32 - 292$

Using a calculator, we have:

$y = 732$

Sin(-180° + θ) = ________

Svet_ta [14]

Answer:

$\sin\left(-180^o+\theta\right)=-\sin\left(\theta\right)$

Step-by-step explanation:

We need to find the value of $\sin(-180^o+ \theta)$

So let's apply formula

$\sin\left(A+B\right)=\sin\left(A\right)\cos\left(B\right)+\sin\left(B\right)\cos\left(A\right)$

$\sin\left(-180^o+\theta\right)=\sin\left(-180^o\right)\cos\left(\theta\right)+\sin\left(\theta\right)\cos\left(-180^o\right)$

$\sin\left(-180^o+\theta\right)=0\cdot\cos\left(\theta\right)+\sin\left(\theta\right)\cdot\left(-1\right)$

$\sin\left(-180^o+\theta\right)=0-\sin\left(\theta\right)$

$\sin\left(-180^o+\theta\right)=-\sin\left(\theta\right)$
