- $\frac{17}{3}$

note that 8 + $\frac{1}{2}$ = 8 $\frac{1}{2}$ = $\frac{17}{2}$

then multiplying the values gives

- $\frac{2}{3}$ × $\frac{17}{2}$ ( cancelling the 2' s )

= - $\frac{17}{3}$ = - 5 $\frac{2}{3}$

Use Euler's formula to derive the identity. (Note that if a, b, c, d are real numbers, a + bi = c + di means that a = c and b =

storchak [24]

Answer with Step-by-step explanation:

We have to prove that

$sin 2\theta=2sin\theta cos\theta$ by using Euler's formula

Euler's formula : $e^{i\theta}=cos\theta+isin\theta$

$e^{i(2\theta)}=(e^{i\theta})^2$

By using Euler's identity, we get

$cos2\theta+isin2\theta=(cos\theta+isin\theta)^2$

$cos2\theta+isin2\theta=(cos^2\theta-sin^2\theta+2isin\theta cos\theta)$

$(a+b)^2=a^2+b^2+2ab, i^2=-1$

$cos2\theta+isin2\theta=cos2\theta+i(2sin\theta cos\theta)$

$cos2\theta=cos^2\theta-sin^2\theta$

Comparing imaginary part on both sides

Then, we get

$sin2\theta=2sin\theta cos\theta$

Hence, proved.

Matt is going to see a hockey game. His ticket cost $25 plus he will pay $3 per food or drink item that he buys from the concess

Ira Lisetskai [31]

Answer: 25+3x

Step-by-step explanation:

His ticket costs $25

Then you add the total cost of the food or drinks, but since you only know the cost but not the amount, x=the amout of items he buys

So x(3) is basically saying $3 + all our food
