Answer:
Step-by-step explanation:
Differentiability at a point implies no sudden changes in the slopes from one side to the other; that is, the derivative must have the same value.
Differentiating x^2 - 6 and 6 - x^2, we get 2x = -2x, whose only solution is zero (0). The two halves of the given function have the same slope (0) at x = 0.

Step-by-step explanation:
Area of a trapezoid =
height * ( sum of base lengths) / 2
So...let the height = h
One base = h + 3
And the other is h + 5
So...we have this
375 = h [ (h + 3 + h + 5 ] / 2 multiply both sides by 2
750 = h [ 2h + 8 ]
750 = 2h^2 + 8h rearrange as
2h^2 + 8h - 750 = 0
Using the quadratic formula....we get the answer ≈ 17.468 = 17.5 yards (rounded)
"b" is correct
For the quadratic equation
ax2+bx+c=0
the formula for the roots is
x=−b±√b2−4
ac2a(1)
Identify the values for
a,b,&cx2+4x+3=0
cmp
ax2+bx+c=0a=1b=4c=3(2)
Substitute these numbers into eh formula
x=−4±√42−(4×1×3)2×1(3)
Carefully proceed and do the calculations
x=−4±√16−122x=−4±√42x=−4±22
now calculate the two separate solutions
x1=−4+22=−22=−1x2=−4−22=−62=−3

You only need to solve one part of the problem, because the second problem is the exact same as the first, so you would do 53 x 6= 318, and 6 x 53 also equals 318
Answer:
I think it would be Malia but if I'm wrong please let me know.
(f + g)(3) = f(3) + g(3).
Find f(3).
f(3) = x + 3
f(3) = 3 + 3
f(3) = 6
Now find g(3).
g(3) = 4x - 3
g(3) = 4(3) - 3
g(3) = 12 - 3
g(3) = 9
We finally add f(3) + g(3).
f(3) + g(3) = 6 + 9
f(3) + g(3) = 15
The answer is 15.
