Without that value, we can't solve your problem, unless you are looking for an algebraic equation.

Which statement correctly describes the relationship between the graph of f(x) and g(x)=f(x+2) ?

coldgirl [10]

Answer:

The graph of g(x) is the graph of f(x) translated 2 units left.

Step-by-step explanation:

When a change is made inside the parenthesis to the input, the function shifts left and right. Addition shifts it left while subtraction shifts it to the right. Here it is translated two units to the left.

Example: f(x) = x $f(x+2) = x_{n+2}$

f(5) = 5 x+2 = 5

x+2-2 = 5-2

x=3 and f(3) = 3

f(5) = 3

This is so because 5 now matches to the output of two previous which is 3.

Whats the Diameter? I really need help understanding this

Arada [10]

Answer:

1.8 in.

Step-by-step explanation:

Hi there!

<u>1) Determine the radius of the base</u>

$V=\frac{1}{3} \pi r^2h$ where r is the radius of the base and h is the height of the cone

Plug in the known values (h=4.2, V=3.6)

$3.6=\frac{1}{3} \pi r^2(4.2)$

Isolate r; divide both sides by 4.2

$\frac{3.6}{4.2} =\frac{1}{3} \pi r^2\\\frac{6}{7} =\frac{1}{3} \pi r^2$

Multiply both sides by 3

$\frac{6}{7}*3 =\pi r^2\\\frac{18}{7}=\pi r^2$

Divide both sides by π

$\frac{18}{7\pi }=r^2$

Take the square root of both sides

$\sqrt{\frac{18}{7\pi }} =r$

<u>2) Determine the diameter</u>

Now that we have the radius, to find the diameter, multiply r by 2:

$d=\sqrt{\frac{18}{7\pi }}*2\\d=1.8$

Therefore, the diameter is 1.8 in. when rounded to the nearest tenth.

I hope this helps!

How should I attempt this question:

Anna35 [415]

You need to divide this problem into two parts
first part is when it was accelerating.. that time use the equation of motion and calculate what is the total angle covered and hence you get the number of revolutions
then find the time of acceleration..so you ll understand for how much did you do the above calculation
for the rest of the time, the speed is constant (final angular speed).. so now you just use
w= theta/ time.. and get theta and again calculate the number of revolutions!
