Answer:
D. d = 
Step-by-step explanation:
Use the distance formula: d = 
The two points are (6, -2) and (3, -9)
Plug the values into the formula:
d = 
Simplify
d = 
d = 
d =
I hope this helps :))
Information about concavity is contained in the second derivative of a function. Given f(x) = ax² + bx + c, we have
f'(x) = 2ax + b
and
f''(x) = 2a
Concavity changes at a function's inflection points, which can occur wherever the second derivative is zero or undefined. In this case, since a ≠ 0, the function's concavity is uniform over its entire domain.
(i) f is concave up when f'' > 0, which occurs when a > 0.
(ii) f is concave down when f'' < 0, and this is the case if a < 0.
In Mathematica, define f by entering
f[x_] := a*x^2 + b*x + c
Then solve for intervals over which the second derivative is positive or negative, respectively, using
Reduce[f''[x] > 0, x]
Reduce[f''[x] < 0, x]
I am sorry, I am so confused
I wish I could help
Answer: Total number of bracelet: 235
Step-by-step explanation:
Given:
Total budget= $1,500
Spend on wire = $250
Per braclet beads = $5.30
Find:
Total number of bracelet
Computation:
Total number of bracelet = [1,500 - 250]
Total number of bracelet = [1,250/ 5.30
Total number of bracelet = 235.849
Total number of bracelet = 235 [By round minium]
Answer:
The answer is D
You have to distribute the x to the 2x + 3 equation
This will result in 2x^2 + 3x
