Answer:
3, in both a), b)
Step-by-step explanation:
a) The slope of the line tangent to the curve that passes through the point (2,-10) is equal to the derivative of p at x=2.
Using differentiation rules (power rule and sum rule), the derivative of p(x) for any x is 
. In particular, the value we are looking for is 
.
If you would like to compute the equation of the tangent line, we can use the point-slope equation to get 
b) The instantaneus rate of change is also equal to the derivative of P at the point x=2, that is, P'(2). This is equal to 
.
Let's solve your equation step-by-step.
−7x=−2x2+15
Step 1: Subtract -2x^2+15 from both sides.
−7x−(−2x2+15)=−2x2+15−(−2x2+15)
2x2−7x−15=0
Step 2: Factor left side of equation.
(2x+3)(x−5)=0
Step 3: Set factors equal to 0.
2x+3=0 or x−5=0
x= 
or x=5
Answer:
x= or x=5

<span>As only one team is to be made that means we have to choose 2 people from total 13 people. As the order that two people are selected does not matter here so we just have to make all possible combination of the team
So the answer is 13*12/2
answer= 78 ways</span>
I’m sorry. But none of your choices are correct. The correct answer would be 3 and 4. Further more explaining= 3+ 2 times 4 is 24. 2x= 4. That equals 8 and 3 times 8 is 24
Answer:
formula is 6a²= surface area
but since one side is not being painted it is
5a²= surface area
5(3.2)²
=51.2cm
