Romeo shot 15 free-throws in last night's game. His coach told him he had an 80% free-throw percentage. How many did he make? (c

Fofino [41]

Answer:

30 throws

Explanation:

Given

Total throw shot by Romeo = 15 throws

If he had an 80% free-throw percentage;

additional throw = 80% of 15

additional throw = 0.8 * 15

additional throw = 12 throws

Toal throws made = 15 + 12

Total throws made = 30 throws

Hence the made 30 throws

"The product of a six and a number increased by four is equal to

NeTakaya

Answer:

$6x + 4 = 12x - 20$

$x = 4$

Step-by-step explanation:

Let "x" be the number.

Product of 6 and x (6*x), increased by 4 = $6x + 4$

Product of 12 and x, (12*x), decreased by 20 = $12x - 20$ .

Set both expressions equal to each other and solve for x as shown below:

$6x + 4 = 12x - 20$ (equation)

Subtract 12 from both sides

$6x + 4 - 12x = 12x - 20 - 12x$

$-6x + 4 = -20$

Subtract 4 from both sides

$-6x + 4 - 4 = -20 - 4$

$-6x = -24$

Divide both sides by -6

$\frac{-6x}{-6} = \frac{-24}{-6}$

$x = 4$

Determine whether each of the following functions is a solution of laplace's equation uxx uyy = 0.

ratelena [41]

Both functions are the solution to the given Laplace solution.

Given Laplace's equation: $u_{x x}+u_{y y}=0$

We must determine whether a given function is the solution to a given Laplace equation.
If a function is a solution to a given Laplace's equation, it satisfies the solution.

(1) $u=e^{-x} \cos y-e^{-y} \cos x$

Differentiate with respect to x as follows:

$u_x=-e^{-x} \cos y+e^{-y} \sin x\\u_{x x}=e^{-x} \cos y+e^{-y} \cos x$

Differentiate with respect to y as follows:

$u_{x x}=e^{-x} \cos y+e^{-y} \cos x\\u_{y y}=-e^{-x} \cos y-e^{-y} \cos x$

Supplement the values in the given Laplace equation.

$e^{-x} \cos y+e^{-y} \cos x-e^{-x} \cos y-e^{-y} \cos x=0$

The given function in this case is the solution to the given Laplace equation.

(2) $u=\sin x \cosh y+\cos x \sinh y$

Differentiate with respect to x as follows:

$u_x=\cos x \cosh y-\sin x \sinh y\\u_{x x}=-\sin x \cosh y-\cos x \sinh y$

Differentiate with respect to y as follows:

$u_y=\sin x \sinh y+\cos x \cosh y\\u_{y y}=\sin x \cosh y+\cos x \sinh y$

Substitute the values to obtain:

$-\sin x \cosh y-\cos x \sinh y+\sin x \cosh y+\cos x \sinh y=0$
The given function in this case is the solution to the given Laplace equation.

Therefore, both functions are the solution to the given Laplace solution.

The correct question is given below:
Determine whether each of the following functions is a solution of Laplace's equation uxx + uyy = 0. (Select all that apply.) u = e^(−x) cos(y) − e^(−y) cos(x) u = sin(x) cosh(y) + cos(x) sinh(y)
