Answer:

SIZE A

32 fluid ounce =2.56

I fuid ounce =2.56/32=0.08

SIZE X

48 fuid ounce = 4.80

I fluid ounce = 4.80/48=0.1

since 0.08 is lesser than 0.1

therefore, that of size A is better

I would appreciate if my answer is chosen as a brainliest answer

#size A

  • 32fluid ounces=$2.56

1 fluid ounce:-

\\ \sf\longmapsto \dfrac{2.56}{32}=0.08

#Size X

  • 48 fluid ounces=4.80$

1 fluid ounce

\\ \sf\longmapsto \dfrac{4.80}{48}=0.1

We can see

0.08<0.1

  • So Size X is better to buy

The mean of a set of numbers is 8, and the mode is 9.
ryzh [129]
You can start by looking at the mode of the set of number automatically b and d are eliminated. We then proceed to calculate the mean so add all the numbers in A so it’ll be, 52 then divide by the amount of numbers in the set so 6. 52/6 =8.6
And C ends up being 48 so 48/6 = 8
Therefore your answer is C

What is the slope of the line tangent to the curve y+2 = (x^2/2) - 2siny at the point (2,0)?
kirza4 [7]
<span>, y+2 = (x^2/2) - 2sin(y) so we are taking the derivative y in respect to x so we have dy/dx use chain rule on y so y' = 2x/2 - 2cos(y)*y'

</span><span>Now rearrange it to solve for y' y' = 2x/2 - 2cos(y)*y' 0 = x - 2cos(y)y' - y' - x = 2cos(y)y' - y' -x = y'(2cos(y) - 1) -x/(2cos(y) - 1) = y'
</span><span>we know when f(2) = 0 so thus y = 0 so when f'(2) = -2/(2cos(0)-1)
</span><span>2/2 = 1
</span><span>f'(2) = -2/(2cos(0)-1) cos(0) = 1 thus f'(2) = -2/(2(1)-1) = -2/-1 = 2 f'(2) = 2

Let f(x, y) = (x + y)e x 2−y 2 and R be the rectangle enclosed by the lines x − y = 0, x − y = 2, x + y = 0, and x + y = 3.
dalvyx [7]

Answer:

(1/4)*(e⁶ - 7)

Step-by-step explanation:

a) Given

x − y = 0  if  x = 0  ⇒  y = 0

x − y = 2  if  x = 0  ⇒  y = -2;  if  y = 0   ⇒  x = 2

x + y = 0  if  x = 0   ⇒  y = 0

x + y = 3  if  x = 0  ⇒  y = 3;  if  y = 0   ⇒  x = 3

then we show the region R in the pics 1 and 2.

b) We make the change of variables as follows

u = x + y

v= x - y

If

x - y = 0  ⇒ v = 0

x − y = 2  ⇒ v = 2

x + y = 0  ⇒ u = 0

x + y = 3  ⇒ u = 3

Where u is the horizontal axis and v is the vertical axis, the new region S is shown in the pic 3.

c) We evaluate ∫∫R (x + y)*e∧(x² - y²)dA

The procedure is shown in the pic 4, where we have to calculate the Jacobian in order to use it to get the answer.
