We have an equation: (5+b)/2= 5
⇒ 5+b= 5*2
⇒ 5+b= 10
⇒ b= 10-5
⇒ b= 5
Final answer: b=5~
Answer: isosceles
Step-by-step explanation:
By the alternate interior angles theorem,
Since angles in a triangle add to 180 degrees,
Since sides opposite equal angles in a triangle are equal, .
So, triangle ABC is <u>isosceles</u>
Answer:
5000
Step-by-step explanation:
In vertex form, the cost function is ...
C(x) = 3(x² -10x) +175 = 3(x² -10x +25) +175 -3(25)
C(x) = 3(x -5)² +100
The vertex is at x=5, so the cost function will be minimized when 5000 speed boats are produced.
Answer: [D]: y = -3x + 2 .
