Answer:

option 3 ⇒ π

Step-by-step explanation:

The general equation of the given function is as following

f(x) = A cos (Bx)

Where A is the amplitude

and B = 2π/period

For the given function f(x) = cos 2x

B = 2

period = 2π/B = 2π/2 = π

a home building contractor bought 4 2/8 acres for $165,000. What was the cost of each acre? (round to nearest dollar.)

pychu [463]

Answer: $38,824

Step-by-step explanation:

Convert the mixed number $4\ \frac{2}{8}$ as a decimal number.

Divide the numerator by the denominator and add it to the whole number 4. Then:

$4+0.25=4.25acres$

Then, knowing that 4.25 acres cost $165,000 , divide this amount by 4.25 acres to find the cost of each acre.

Therefore, you get that the cost of each acre rounded to nearest dollar is:

$cost=\frac{\$165,000}{4.25}\\cost=\$38,824$

I don’t understand constant rates of change help!

REY [17]

Answer:

The (constant) rate of change with respect to the variable x of a linear function y = f(x) is the slope of its graph. If x and f have units in Definition 2, then the units of the rate of change are those of f divided by those of x.
