Answer:
width = 8 feet and length = 29 feet
Step-by-step explanation:
perimeter of a rectangle P = 2(L + W)
width W = x
length L = 3x + 5
P = 74 feet
74 = 2(3x + 5 + x)
37 = 3x + 5 + x
37 = 4x + 5
4x = 37 -5
4x = 32
x = 8
W = 8 feet
Answer:
Step-by-step explanation:
I will ASSUME you mean y = 3x² at x = 2
The derivative of an equation is the slope the curve at any given point
y' = 6x
so our line slope at x = 2 is 6(2) = 12
at x = 2, y = 3(2²) = 12
so (2, 12) is a point on the line (the point of tangency)
plugging into our slope equation
y = 12x + b
12 = 12(2) + b
b = -12
So the equation of the line tangent to y = 3x² at x = 2 is
y = 12x - 12

Step-by-step explanation:
Answer:
The logarithmic function for x = 2y is written as y = log2 x or f(x) = log2 x. The number 2 is still called the base. In general, y = logb x is read, “y equals log to the base b of x,” or more simply, “y equals log base b of x.” As with exponential functions, b > 0 and b ≠ 1
