Solve the equation 3x=5(x+3)-3

1 answer:

4 0

3x = 5(x + 3) - 3 |use distributive property: a(b + c) = ab + ac

3x = 5x + 15 - 3

3x = 5x + 12 |subtract 5x from both sides

-2x = 12 |divide both sides by (-2)

x = -6

Answer/Step-by-step explanation:

Total Distance = 3Ft

a) Determine the amplitude and period of a sinusoidal function that models the bobbing buoy.

Amplitude = 3/2 = 1.5 period = 10 second

$\frac{0}{1} =\frac{2\pi }{b}$ $b=\frac{\pi }{5}$ No ph. Shift

b) Write an equation of a function that models the buoy with x=0 at its highest point.

y= 1.5 cos ( $\frac{\pi }{5} x$ )

The volume of a sphere whose diameter is 18 centimeters is how many cubic centiemters

Arturiano [62]

Answer:

3053.63 cm^3

Step-by-step explanation:

Volumme of a sphere = $\frac{4}{3}\pi*r^3.$

We do not have the radius of the sphere, but we have its diameter.

We know that there is a relationship between radius and diameter.

$d = 2r\\r = \frac{d}{2}$

Then the formula of the volume of a sphere according to its diameter is:

$\frac{4}{3}\pi (\frac{d}{2}) ^ 3\\\\\frac{4}{3}\pi(9)^3 = 972\pi = 3053.63 cm^3\\\\$

An ice cream store uses 1/5 of a box of ice cream cones everyday. If they have 8 boxes, how many days will they last? Write the

Ad libitum [116K]

Answer:

1.6 days (1 3/5 for simplified form).

Step-by-step explanation:

Given equation:

1/5 * 8

We know that a box survives 1/5 a day.

1/5 * 8 = 1 3/5

It will survive 1 3/5 a day in 8 boxes.
