Answer:

$\displaystyle {r}^{} = 6$

Step-by-step explanation:

remember that,

$\displaystyle V _{ \rm sphere} = \frac{4}{3} \pi {r}^{3}$

given that,

V=288π

thus substitute:

$\displaystyle \frac{4}{3} \pi {r}^{3} = 288\pi$

divide both sides by 4/3π:

$\displaystyle {r}^{3} = 216$

cubic root both sides:

$\displaystyle {r}^{} = 6$

and we are done!

Ln (1/x)+ln (2x^3)=ln3

Lapatulllka [165]

$\ln \frac{1}{x} +\ln2x^3=\ln3$
$\ln \frac{2x^3}{x} = \ln3$
$\ln2x^2=\ln3$
$2x^2=3$
$x=\sqrt{ \frac{3}{2} }$

At the movie theatre, child admission is $5.10 and adult admission is $9.70. On Thursday, 128 tickets were sold for a total sale

kvv77 [185]

Answer:

Step-by-step explanation:

Let x be the number of children tickets sold and y be the number of adult tickets sold. Then

x+y=128.

The cost of x children tickets is $5.10x and the cost of y adult tickets is $9.70y, so

5.10x+9.70y =896.60.

From the first equation,

x=128-y,

then

$5.10(128-y)+9.70y=896.60,\\ \\652.80-5.10y+9.70y=896.60,\\ \\4.60y=243.8,\\ \\y=53.$

53 adult tickets were sold.

Let f(x)=3^x

suter [353]

As your -2 is directly affecting the x with addition/subtraction, it is a translation horizontally. To find direction, change the sign, from negative to positive, making it go right. This means it will be translated 2 units to the right, fitting the first statement. For your +5, it is not directly affecting the x, making it a translation vertically. As it's positive, it goes up, making it a translation 5 units up, fitting statement 4. This makes your correct statements 1 and 4.
