Each quilt takes 3 yards of material so it would be 36
The answer is a
lmk if you need the work
Answer:
Step-by-step explanation:
Given is a function in f as
We can change base to e for our convenience for finding derivatives
The second term is a constant with value = 0.434294
So f(x) = 0.434294 ln x
Now differentiate with respect to x two times
I derivative =
Note: We can leave as log e to base 10 also without converting into actual values.
Answer: B) The function is decreasing
Step-by-step explanation:
As x increases, y decreases.
Answer: 17.9
Step-by-step explanation:
Using Heron's formula:
Area of a triangle is given by:
√s(s-a)(s-b)(s-c)
Where a, b and c ara sides of the triangle and
S = (a+b+c) / 2
In the question above sides are :
XY=XZ= 20 and YZ=18
S = (20 + 20 + 18) / 2 = 58/2 = 29
Area = √29(29-20)(29-20)(29-18)
Area = √29(9)(9)(11)
Area = √25839
Area = 160.74513
Altitude = height(h)
Area = 0.5 × base × height
Base = yz = 18
160.74513 = 0.5 × 18 × h
160.74513 = 9 × h
h = 160.74513 / 9
h = 17.9 (3 s.f)
