Answer:
The maximum will be 78
Step-by-step explanation:
yes
72/12 = 6
66/11 = 6
6 = 6
x-y=21 ⇒ x=y+21
x+13=2y
Substitute y+21 for x into the equation x+13=2y
So y+21+13=2y
Simplify 34=y
So Danielle is 34 years old. Plug y back in to the original equation
x-34=21
x=55
Tony is 55 years old
Answer:
13/9
y =-22x+32
Step-by-step explanation:
Given that the functions f and g are differentiable for all real numbers x. The table below gives values for the functions and their first derivatives at selected values of x.
x f(x) f'(x) g(x) g'(x)
1 4 -3 5 2
2 -3 -1 4 6
3 π 8 -1 4
4 -5 unknown 0 3
a) 
(using quotient rule)
Substitute 1 for x

b) 
when 
point of contact is (2,-12)
Slope of tangent =
Using point slope form, tangent is

Answer:
C. 50 degrees.
Step-by-step explanation:
The angles of the triangle add up to 180. So the remaining angle is 50.
