Answer:
3, in both a), b)
Step-by-step explanation:
a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.
Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is . In particular, the value we are looking for is .
If you would like to compute the equation of the tangent line, we can use the point-slope equation to get
b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to .
Answer:
the natural process of laying down a deposit of something
Step-by-step explanation:
What you must do for this case is to solve the system of two equations with two unknowns.
To find the values of x and y.
We have then:
-3x + 9y = 36
4x + 12y = 24
Resolving:
Step 1:
(1/3) * (- 3x + 9y) = (36) * (1/3)
(1/4) * (4x + 12y) = 24 * (1/4)
-x + 3y = 12
x + 3y = 6
Step 2:
6y = 18
y = 18/6
y = 3
Step 3:
-x + 3y = 12
-12 + 3y = x
-12 + 3 (3) = x
x = -3
answer:
x = -3
y = 3
Answer:
Hi there!
The answer to this question would be:
Step-by-step explanation:
the general equation would be: y= -1/2x + 17/2
first you want to solve for the slope (m): you wanna do delta y (change of y ) over delta x (change of x)
so it goes like (11-9)/(-5-(-1)) and you get -1/2
then you want to solve for the y intercept (b)
so you plug in one of the point that you were given, in this case I am using (-1,9)
so now the equation looks like 9 = 1/2 +b then solve for b and you get b=17/2
