What angle has the same sine value between 0-180? as Sin 24

Inessa05 [86]

Answer:

$Sin156$

Step-by-step explanation:

Given

$Sin24$

Required

Find equivalent between 0 to 180;

Let 24 be represented by $\theta$

So, $\theta = 24$

From Trigonometry ratios;

$Sin\theta = Sin(180 - \theta)$ where $0\leq \theta \leq 180$

Recall that $\theta = 24$

So, we have to substitute 24 for $\theta$ in the above expression.

This gives

$Sin24= Sin(180 - 24)$

Subtract 24 from 180

$Sin24= Sin156$

Hence, the equivalent of $Sin24$ is $Sin156$

5 hamburger packages and 6 bun packages

Step-by-step explanation:

It is asking for the highest common multiple of 12 and 10. the first time a multiple of 12 is divisible by 10 is at 12x5, which is 60. now divide 60 by 12 and 10, 5 and 6.

Evaluate the following double integral where a = 2y

Keith_Richards [23]

Change the order of integration.

$\displaystyle \int_0^1 \int_{2y}^2 \cos(x^2) \, dx \, dy = \int_0^2 \int_0^{x/2} \cos(x^2) \, dy \, dx \\\\ ~~~~~~~~ = \int_0^2 \cos(x^2) y \bigg|_{y=0}^{y=x/2} \, dx \\\\ ~~~~~~~~ = \frac12 \int_0^2 x \cos(x^2) \, dx$

Substitute $u=x^2$ and $du=2x\,dx$ .

$\displaystyle \frac12 \int_0^2 x \cos(x^2) \, dx = \frac14 \int_0^4 \cos(u) \, du = \frac14 \sin(u) \bigg|_{u=0}^{u=4} = \boxed{\frac{\sin(4)}4}$
