Answer:

y = 4x - 18

Step-by-step explanation:

Write out y = mx + b.

The slope of the line in question is 4.  Thus we have y = 4x + b.

Finally, substitute -6 for y, 3 for x and solve for b:

-6 = 4(3) + b, or -6 = 12 + b.  Then b = -18, and the equation of this line is

y = 4x - 18

icang [17]

Answer:

V = 128π/3 vu

Step-by-step explanation:

we have that: f(x)₁ = √(4 - x²);  f(x)₂ = -√(4 - x²)

knowing that the volume of a solid is  V=πR²h, where R² (f(x)₁-f(x)₂) and h=dx, then

dV=π(√(4 - x²)+√(4 - x²))²dx;  =π(2√(4 - x²))²dx ⇒

dV= 4π(4-x²)dx , Integrating in both sides

∫dv=4π∫(4-x²)dx , we take ∫(4-x²)dx and we solve

4∫dx-∫x²dx = 4x-(x³/3) evaluated -2≤x≤2 or too 2 (0≤x≤2) , also

∫dv=8π∫(4-x²)dx evaluated 0≤x≤2

V=8π(4x-(x³/3)) = 8π(4.2-(2³/3)) = 8π(8-(8/3)) =(8π/3)(24-8) ⇒

V = 128π/3 vu

A. 37<br> B. 38<br> C. 39<br> D. 40
Dvinal [7]

Hello ^w^

I believe the answer you are looking for is A

I found this answer by adding up the lengths of all the sides.

S -> T = 8

S -> R = 7

Q -> R = 6

P -> Q = 6

P -> T = 10

10 + 6 + 6 + 7 + 8 ->  37

A -> 37

If I am incorrect, please inform me.

Have a good day!

This recipe makes 5 portions of potato soup.
Sindrei [870]

Answer:

90 mL oil

210 g onions

1,350 g potatoes

1,500 mL milk

Step-by-step explanation:

You would just multiply each thing by 3, because the original recipe is for 5 but he wants to make it for 15, which is 3 times the original

Differentiate <br> y=(r^2-9r)e^r
Alex Ar [27]

Differentiate

y = (r² – 9r) · eʳ

with respect to  r.


As  y  is a product of two functions, then use the product rule:

 dy          d
——  =  —— [ (r² – 9r) · eʳ ]
 dr         dr

 dy          d                                                d
——  =  —— (r² – 9r) · eʳ  +  (r² – 9r)  ·  —— (eʳ)
 dr         dr                                               dr


•  The derivative of  r² – 9r  is  2r – 9;

•  The derivative of  eʳ  is  eʳ.


Therefore,

 dy                                               
——  =  (2r – 9) · eʳ  +  (r² – 9r) · eʳ
 dr 

 dy
——  =  [ (2r – 9) + (r² – 9r) ] · eʳ
 dr

 dy
——  =  (r² – 7r – 9) · eʳ   <———    this is the answer.
 dr


I hope this helps. =)
