Answer:
b = 0.7w
Step-by-step explanation:
To make a shade of blue paint :
3 1/2 quarts of blue
5 quarts of white
3 1/2 α 5
7/2 = 5k
Where k is the proportionality constant
k = 7/2 ÷ 5
k = 7/2 * 1/5
k = 7/10
k = 0.7
To mix :
b quartz of blue with w quartz of white
b = kw
b = 0.7w
The answer for that question is Angle bisectors
Answer:
3+3x+7 or 3x+10
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. x is treat any other variable as a constant.
dz/dx=0-2x-0
dz/dx=-2x
Evaluating this at (7,-3) gives us dz/dx=-2(7)=-14.
Since this result is negative, it mrans as x increases z decreases.
f(x,y)=10-x^2-y^2
To find derivative of z w.r.t. y is treat any other variable as a constant.
dz/dx=0-0-2y
dz/dx=-2y
Evaluating this at (7,-3) gives us dz/dy=-2(-3)=6.
Since this result is positive it mrans as y increases z decreases.
The answer is d. angles 8 and 16
