Hi , anyone can help?​
I am Lyosha [343]

Step-by-step explanation:

AS = Asri's height

AD = Adib's height

IR = Irfan's height

AS = 2x

AD = AS - 6 = 2x - 6

IR = 2 × AS = 2 × 2x = 4x

i)

IR = 4x

ii)

IR - AS = 4x - 2x = 2x

Finding Derivatives Implicity In Exercise,Find dy/dx implicity.<br> x2e - x + 2y2 - xy = 0
Klio2033 [76]

Answer:

the question is incomplete, the complete question is

"Finding Derivatives Implicity In Exercise,Find dy/dx implicity . x^{2}e^{-x}+2y^{2}-xy"

Answer : \frac{dy}{dx}=\frac{y-(2-x)xe^{-x}}{(4y-x)}

Step-by-step explanation:

From the expression  x^{2}e^{-x}+2y^{2}-xy" y is define as an implicit function of x, hence we differentiate each term of the equation with respect to x.

we arrive at

\frac{d}{dx}(x^{2}e^{-x )+\frac{d}{dx} (2y^{2})-\frac{d}{dx}xy=0\\

for the expression \frac{d}{dx}(x^{2}e^{-x}) we differentiate using the product rule, also since y^2 is a function of y which itself is a function of x, we have

(2xe^{-x}-x^{2}e^{-x})+4y\frac{dy}{dx}-x\frac{dy}{dx} -y=0\\\\(2-x)xe^{-x}+(4y-x)\frac{dy}{dx}-y=0 \\.

if we make dy/dx  subject of formula we arrive at

(4y-x)\frac{dy}{dx}=y-(2-x)xe^{-x}\\\frac{dy}{dx}=\frac{y-(2-x)xe^{-x}}{(4y-x)}

Regina bought 1 apple for $0.75 and 8 bananas. She spent $4.35. How much was each banana?
Degger [83]
A = 0.75
To figure out how much each banana was, subtract the cost of the apple.
4.35 - 0.75 = 3.60.
Divide 360 by 8.
3.60/8 = .45
Each banana costed $0.45
I hope this helps!

Please help, I am terrible at math
Zarrin [17]

Answer:

the correct option is D (12 units, 14 units, 10 units)

Step-by-step explanation:

P= 36

2t + 2 + 2t + 4 +2t = 36

combine like terms

6t + 6 = 36

subtract 6 from both sides

6t = 30

30/6 = 5

T = 5 so plug the t in the other equations

2(5) + 2 = 10 + 2 = 12

2(5) + 4 = 10 + 4 = 14

2(5) = 10

To check combine all the numbers above and you would get 36
