Solve the formula for the specified variable. D=1/2fk for f f=

1 answer:

4 0

We are asked to solve the formula $D=\frac{1}{2}fk$ for $f$ . Starting off, we can divide both sides by $k$ , so we are left with only the variable $f$ on the right-hand side. Next, we need to multiply the reciprocoal of $\frac{1}{2}$ , which is $2$ to both sides. This gives us $2*\frac{D}{k}=f$ , which, when simplified, gives us $\boxed{f=\frac{2D}{k}}$ . Hope this helped and have a phenomenal day!

Answer:

109.9 ft

Step-by-step explanation:

The length of an arc that is 1/4 of a circle of radius 70 ft is ...

s = rθ

s = (70 ft)(π/2) = 35π ft ≈ 109.9557 ft

The best answer choice appears to be 109.9 feet.

An alternative definition for the acceleration ax that can be written in terms of $v_x$ and $\frac{dv_x}{dx}$ is $a_x=v_x \frac{dv_x}{dx}$

Step-by-step explanation:

We know that :

$a_x=\frac{dv_x}{dt}$

Now we are supposed to find an alternative definition for the acceleration ax that can be written in terms of $v_x$ and $\frac{dv_x}{dx}$

So, We will use chain rule over here :

$a_x=\frac{dv_x}{dt}\\a_x=\frac{dv_x}{dt} \times \frac{dx}{dx}\\a_x=\frac{dv_x}{dx} \times \frac{dx}{dt}\\a_x=\frac{dv_x}{dx} \times \frac{dx}{dt} [\frac{dx}{dt}=v_x]\\a_x=\frac{dv_x}{dx} \times v_x\\a_x=v_x\frac{dv_x}{dx}$

Hence an alternative definition for the acceleration ax that can be written in terms of $v_x$ and $\frac{dv_x}{dx}$ is $a_x=v_x \frac{dv_x}{dx}$
