Answer:

dy/dx = (2 -x)/40.005

Step-by-step explanation:

(a) Solving the x-equation for u gives ...

  u = (x -1)/4

Differentiating both equations with respect to u, we have ...

  dy/du = 1 -4u

  dx/du = 4

Then dy/dx is ...

  dy/dx = (dy/du)/(dx/du) = (1 -4u)/4

Substituting for u gives ...

  dy/dx = (1 -4(x -1)/4)/4

  dy/dx = (2 -x)/4

__

(b) The approximate change in y is ...

  ∆y ≈ (dy/dx)(∆x)

For ∆x = 2.98 -3.00 = -0.02, and x=3, the approximate change is ...

  ∆y ≈ (2 -3)/4(-0.02)

  ∆y ≈ 0.005

To tie-dye one T-shirt 3/8 cup of dye is needed. the table shows the number of cups of each color of dye in Mr. Galvez's art class. how many t-shirts can be made using only orange dye?

Amount of Dye
red: 12
orange:3/4

Answers

Answer:

Two shirts can be made

Step-by-step explanation:

We do have 3/4c of orange dye.

We do require 3/8c per T-shirt.

But, using math, it can be shown that 3/4c=2×3/8c

Looking at it this way: 3/4c = 2x3/8c

Where the 2 is the number of T-shirts we can produce.

It is easy now to see: 3/4c = 2x3/8c = 6/8c

So: 34c=68c=34c→ and all of this is orange dye

Answer:

y=8x+3

Step-by-step explanation:

to check plug the numbers to the equation and you will that it is right

Answer:

f(x) = 8x + 3

Explanation:

I knew f(x) = mx +b is the formula for a linear equation and that when x = 0,

f(x) = b

So, when x = 0 in the table, f(x) = 3 and therefore b = 3

Now we can plug in f(x) = 11 and x =1 into f(x) = mx+b along with our b value

11 = m(1) + 3

solving for m we get m  =  8 which finishes our unknowns

f(x) = mx + b

f(x) = 8x + 3

Sales Revenue ; Quarter 1 = $120 million Sale Revenue ; Quarter 2 = $120 - $10 = $110 million

Quarter 1 :

East = $78 million East percentage = (78/120) × 100% = 65%West = 120 - 78 = $42 million West percentage = 100% - 65% = 35%

Quarter 2 :

West = $42 + $46 = $88 million West percentage = (88/110) × 100% = 80%East = $110 - $88 = $22 million East percentage = 100% - 80% = 20%

What are integers?

A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero.

Given that, the product of three integers is -40.

Since the product is negative, there should be at least one negative number.

The three numbers can be 8, -5, and 1.

8 × (-5) ×1 = -40
