Answer:
-40
-6
51
Step-by-step explanation:
-33+-7 you are adding two negatives
9+(-15) you are adding a negative to a positive which gets you closer to zero
5-(-46) you are subtracting a negative which is adding
Answer:6.928
Step-by-step explanation: formula A=√ 3*(side^2/4)
First, you need to find the derivative of this function. This is done by multiplying the exponent of the variable by the coefficient, and then reducing the exponent by 1.
f'(x)=3x^2-3
Now, set this function equal to 0 to find x-values of the relative max and min.
0=3x^2-3
0=3(x^2-1)
0=3(x+1)(x-1)
x=-1, 1
To determine which is the max and which is the min, plug in values to f'(x) that are greater than and less than each. We will use -2, 0, 2.
f'(-2)=3(-2)^2-3=3(4)-3=12-3=9
f'(0)=3(0)^2-3=3(0)-3=0-3=-3
f'(2)=3(2)^2=3(4)-3=12-3=9
We examine the sign changes to determine whether it is a max or a min. If the sign goes from + to -, then it is a maximum. If it goes from - to +, it is a minimum. Therefore, x=-1 is a relative maximum and x=1 is a relative miminum.
To determine the values of the relative max and min, plug in the x-values to f(x).
f(-1)=(-1)^3-3(-1)+1=-1+3+1=3
f(1)=(1)^3-3(1)+1=1-3+1=-1

Answer:
Number of cards given to sister = 35 card
Step-by-step explanation:
Find baseball card on Monday = 12
Find baseball card on Tuesday = 12 + 24 = 36
Remain baseball card = 13
Find:
Number of cards given to sister
Computation:
Number of cards given to sister = Find baseball card on Monday + Find baseball card on Tuesday - Remain baseball card
Number of cards given to sister = 12 + 36 - 13
Number of cards given to sister = 35 card
The answer would be -0.5 hope this helped!
