Answer:
the center is (-2,2) and the radius is 5
Answer with Step-by-step explanation:
We are given that an equation of curve
We have to find the equation of tangent line to the given curve at point
By using implicit differentiation, differentiate w.r.t x
Using formula :
Substitute the value x=
Then, we get
Slope of tangent=m=
Equation of tangent line with slope m and passing through the point is given by
Substitute the values then we get
The equation of tangent line is given by
This is required equation of tangent line to the given curve at given point.
For number one you do 15-9 which is 6 and that’s the answer
For number to do 25-18 which is 7 and that’s the answer for that one
Answer:
75
Step-by-step explanation:
Area of a triangle is <em>l </em>x <em>w </em>(length x width)
That's 4 cm x 12 cm. Now you could go ahead and figure it out from there, but you have to remember it wants the answer in meters. It tells us that for every 4cm, it is 5m. The easiest way to figure this out is to convert to meters before multiplying. Since 4 cm is 5m, the <em>l </em>becomes 5m. 4 goes into 12 three times. So we would do 5 x 3 to get 15m for the new <em>w. </em>Now we can solve for area.
<em>l </em>x <em>w </em>= A
5m x 15m = A
75m = A
I hope this helped :)
