If L= m+ f, then to find f, u move m to the other side. So u subtract it. Cause you have to do the opposite. So f= L-m

L is in the green box

The chance that you make a three-point shot in a basketball game is 30%. How many three-point shots would you expect to make if

Ganezh [65]

So 3 in every 10 would make it because 30% equals 3/10 and since there are 50 that would be 5 sets of 10. Thus 3*5=15. You would make 15 shots

Linear Equations In Any Form. Help ASAP Please

Ronch [10]

The answer is y = 3/4 x + 2

<em>Explanation:</em>

Basically, the formula for a linear equation is y = mx + b

b = y-intercept

mx = slope

slope = rise/ run (pos.)

it can also be fall/ crawl (neg.)

In the graph the line meets at the y-int. at 2, the line rises 3 and goes right 4 each time.

Find dy du , du dx , and dy dx .

dangina [55]

Answer:

a) $\frac{dy}{du}=5(x^2 +1)^4$ , $\frac{du}{dx}=2x$ , $\frac{dy}{dx}=10x(x^2+1)^4$

b) $\frac{dy}{du}=4(4x^2-x+6)^3$ , $\frac{du}{dx}=8x-1$ , $\frac{dy}{dx}=4(8x-1)(4x^2-2+6)^3$

Step-by-step explanation:

We can use the chain rule in the following form: is u=u(x) is a differentiable function depending on x and y=y(u) is a differentiable function depending on u, then $\frac{dy}{dx}=\frac{dy}{du} \frac{du}{dx}$ .

a) $\frac{dy}{du}=\frac{d}{du} (u^5)=5u^4=5(x^2 +1)^4$ from the power rule.

$\frac{du}{dx}=\frac{d}{dx} (x^2 +1)=2x$ .

From the previous parts and the chain rule, $\frac{dy}{dx}=\frac{dy}{du} \frac{du}{dx}=5(x^2 +1)^4(2x)=10x(x^2+1)^4$

b) $\frac{dy}{du}=\frac{d}{du} (u^4)=4u^3=4(4x^2-x+6)^3$

$\frac{du}{dx}=\frac{d}{dx} (4x^2-x+6)=8x-1$ from the power and sum rules.

Then, $\frac{dy}{dx}=\frac{dy}{du} \frac{du}{dx}=4(4x^2 -x+6)^3(8x-1)=4(8x-1)(4x^2-x+6)^3$
