Answer:
dy/dx = (2 -x)/40.005Step-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

Question Arrange the sales revenue lo 000.0001) by Quirtor und the percentages in the East and West regions
The required revenue table categorized by Quarter (Qrt1 and Qrt 2) and Region (East and West) is :

Sales Revenue ; Quarter 1 = $120 million Sale Revenue ; Quarter 2 = $120 - $10 = $110 millionQuarter 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%Therefore, The distribution table which displays the revenue of the comp may is given above.

Find the area of this figure to the nearest hundredth. Use 3.14 to approximate pi.
(The figure is a right triangle conjoined to a semi-circle. The semi-circle's diameter is 8, the triangle's base is 6, the triangle's height is 8. )
Answer:
49.12 square units
Step-by-step explanation:
Area of triangle = [tex]\dfrac{1}{2}*base *height[/tex]
[tex]=\dfrac{1}{2}*6*8=3*8 = 24 \ sq.units[/tex]
Circle:
d = 8 units
r = 8/2 = 4 units

The three integers could be 8, -5, and 1.
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
Hence, the three integers could be 8, -5, and 1.

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
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

Step-by-step explanation:
If you have 61 numbers, the middle number is the median. 30 numbers are below the median and 30 numbers are above the median. The middle number is the 61 number. At most and at least 30 numbers can be above the median. I think the statement is true.
Triangle proportions pls help w/ work
Answer:
64
Step-by-step explanation:
Let the missing side be " x "
30 / ( 30 + 10 ) = 48 / x.
30 / 40 = 48 / x
3 / 4 = 48 / x
3 * x = 4 * 48
x = 4 * 48 / 3
= 4 * 16
x = 64
