Find the partial derivatives of the function w=4r2+6s2+

Mathematics

I'm taking the liberty of editing your function as follows:  <span>w=4r^2+6s^2, where I use " ^ " to indicate exponentiation.

The partial of w with respect to r is 8r.  That with respect to s is 12s.</span>

Which equation is written in slope-intercept form?
zhuklara [117]

Answer:

<h2>A. y = 3x - 2</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

<em>y = mx + b</em>

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have

<em>A. y = 3x - 2   - it's the slope-intercept form</em>

<em>B. x = 1/2y + 8   </em><em>NOT</em>

<em>C. 2x + 5y = 12 </em><em>NOT</em><em> - it's the standard form</em>

<em>D. 3y = 8x - 5  </em><em>NOT</em>

Kwan hiked up a hill at 4 km/h and back down at 6 km/h. His total hiking time was 3 hours. How long did the trip up the hill tak
Leya [2.2K]

Let the time to hike up the hill  = t

As given that the total time time up and down is 3 hrs,  therefore

The time down the hill = 3-t

The distance up and down is the same.

Distance = speed * time

4t=6(3-t)

4t=18-6t

10t=18

t=1.8

Hence, time taken to uphill = 1.8 hours

Time taken to down hill = 3-18 = 1.2 hours

​Ramona's Garage charges the following labor rates. All customers are charged for at least 0.5 hr.
algol13

Answer:

a. The linear function is given by,

y = 60x + 30  [y is in $ and x is in hour and x ≥ 0.5]

  = 60 [for x < 0.5]

b. The total cost of the repair job is,  $ 675 .

Step-by-step explanation:

Let, the linear function describing garage charge( y in $) and no. of hours of repair job ( x in hour) be,

y = mx + c    [for x ≥ 0.5]  -----------(1)

where, m is the slope of the line and c is the y intercept.

Now ,

m = \frac {90 - 60}{1 - 0.5}

  = 60  ----------------(2)

Now, putting the value of m and the point (x,y) = (0.5, 60) in (1), we get,

60 = 60 \times 0.5 + c $

⇒ c = 30 ----------------- (3)  

Hence, the linear function is given by,

y = 60x + 30  [y is in $ and x is in hour and x ≥ 0.5] ------------(4)

  = 60 [for x < 0.5]

Now, putting

x = 4 hr 15 min

= 4\dfrac {15}{60} hour

= 4.25 hour in (4), we get,

y = 60 \times 4.25 + 30  [in $]

= $ 285

So, the total cost of the repair job,

= $ (285 + 390)

= $ 675

The ratio of the lengths of corresponding parts in two similar solids is 4:1.
Rina8888 [55]

Answer:

the ratio is 16:1

Step-by-step explanation:

surface area is measured in square units, so you should square both numbers in the linear ratio to get the ratio for the surface area.

4^{2} : 1^{2} -->16:1
