The answer is a=-2 and have a nice day
Answer:
Step-by-step explanation:
Maximum rate of change of a function f(x,y) is expressed as the gradient of such function at the given point. Gradient of a function is expressed as;
∇f(x,y) =
Given f(x,y)=ln(x²+y²) at the point (-2, 2)
<em>Hence the maximum rate of range of the function at the point (-2,2) is </em><em></em>
To get the direction, we willl use the formula;
From the vector gotten, x = -1/2 and y = 1/2
<em>Since tan theta is negative in the second quadrant, the direction in which it occurs will be 180-45 = 135°</em>
The y intercept is 5, since slope is y=mx+b. The x intercept is at -2. If you have more problems like this there is an amazing calculator that graphs equations like this for you. www.symbolab.com. Hope this helps!
Answer:
The slope is 1 hope this helps
y²-y¹/x²-x¹
6-(-4)/7-(-3)
10/10 =1
Answer: B. y=2.49x+5.57
Step-by-step explanation:
First, add the prices from the two items you know for sure the cost. You know gas is 2.49 a gallon but you do not know how much she bought. X will represent the amount of gallons, since it is unknown. hope is helps maybe someone can answer my math
