Answer:
Step-by-step explanation:
Equation of a line:
The equation of a line, in point-slope form, has the following format:
In which the point is 
and the slope is m.
(3, 20)
This means that 
. So
Slope:
The slope is the derivative of the function at the point:
The function is:
The derivative is:
At the point, we have that 
. So
So the equation to the tangent line to the curve a the point is:
B=1
5(b-4)+25=5x6-5x4
5b-20+25=30-20
5b+5=10
5b=5
B=1
Answer:
IM not too sure but i think 30
Step-by-step explanation:
Answer:
Step-by-step explanation:
Calculate the length (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 3) and (x₂, y₂ ) = (0, 7)
d = 
= 
= 
= ≈ 4.1 ( to 1 dec. place )
