A generic point on the graph of the curve has coordinates
The derivative gives us the slope of the tangent line at a given point:
Let k be a generic x-coordinate. The tangent line to the curve at this point will pass through and have slope
So, we can write its equation using the point-slope formula: a line with slope m passing through has equation
In this case, and , so the equation becomes
We can rewrite the equation as follows:
We know that this function must give 0 when evaluated at x=0:
This equation has no real solution, so the problem looks impossible.
Answer:
x=30
Step-by-step explanation:
2x+x+90=180 (anglesome prop.)
3x+90=180
3x=180-90=90
3x=90
x=90/3=30
Answer:
Yes
Step-by-step explanation:
To find this out, all you have to do is plug in the given value to the equation
3x - 1 = 5x + 10
3(-5 1/2) - 1 = 5(-5 1/2) + 10
-17.5 = -17.5
Answer:
- City A was the warmest
- City B was the coolest
Step-by-step explanation:
If we list the temperatures from lowest to highest, they are 58, 60, 64, 68. The highest temperature was the warmest. It was recorded in City A.
The lowest temperature was the coolest. It was recorded in city B.
City A was the warmest; city B was the coolest.
