Answer: y=2x+13

Step-by-step explanation: So you need to find the equation y=mx+b

So to find slope (m) you need to do is rise over run. So your slope would be 2.

Now we need to find your y-intercept (b). Your y-intercept would be 13. so your equation for the line of best fit would be y=2x+13

I hope this helped.

An artist purchased 24 high quality canvases to be used for painting this fall. Each week she will allow herself to use three of

Nadusha1986 [10]

Answer:

canvases over weeks

Step-by-step explanation:

Given:

w(h) represents how many hours per week

c(t) approximates how many canvases she paints per hour

In function composition, if we have two function f(x) and g(x) then

(f.g)(x) or f(g(x)) means first apply g(), then apply f() i.e. applying function f to the results of function g.

Now we have c(w(h)), this means first we apply w(h) which will give us hours per week and then we'll apply function 'c' on the results of 'w' (that is number of hours for weeks painted). As result we'll get number of canvas per week!

The height of the tunnel at the center is 35ft, and the vertical clearance must be 21 ft at a point of 8ft from the center. Find

Zinaida [17]

Answer:

y=-0.215x^2+35

Step by Step:

Let, $h=0$ , $k=35$ , $x=8$ , $y=21$

We know that, the general equation of the parabola.

$y-k = a(x-h)^2$

$\Rightarrow y=a(x-h)^2+k .........(i)$

Substitute the value of $h, k, x, y$ in equation $(i)$ and find the value of $a.$

$21=a(8-0)^2+35$

$\Rightarrow 21=a\times 8^2+35$

$\Rightarrow 21=64a+35$

$\Rightarrow 64a=21-35$

$\Rightarrow 64a=-14$

$\Rightarrow a=\frac{-14}{65}$

$\Rightarrow a=-0.215$

Hence, the equation of the parabola is:

$y=-0.215x^2+35$

On a typical day flights at a local airport arrive at a rate 10 every 15 minutes at this rate how many would you expect to arriv

harina [27]

How many times do 15 minutes fit into one hour? 4 times: 4*15=60 mins.

So that means that 4 times per hour 10 flights appear, and in total 4*10=40 planes arrive over one hour!
