Answer:

\frac{C}{4} = \pi

Step-by-step explanation:

Circumference(C) of a circle is given by:

C = 2 \pi r               ....[1]

where, r is the radius of the circle.

As per the statement:

Given a circle with a diameter of 4.

We know that:

Diameter(D) = 2r

⇒2r = 4

Substitute the value in [1] we have;

C = \pi \cdot (2r)

⇒C =4\pi

Divide both sides by 4 we have;

\frac{C}{4} = \pi

Therefore, the  the ratio of the circumference of a circle to its diameter is, \frac{C}{4} = \pi

Which answer choice is equivalent to the expression below?
Bess [88]

Answer:

the answer would be -13n-23

Step-by-step explanation:

first you want to distribute the brackets

-7(2+n) = -14-7n

+(-9-6n)

-9-6n

-14-7n-9-6n

combine the n value with an n value and an integer that doesn't have an n value

-7n-6n-14-9

= -13n-23

Select the correct answer. Evaluate the following expression when x = -4 and y = 4. A. B. C. D.
andriy [413]

The value of given expression when x=-4 and y=4 is 1250.

The expression is missing in the question which is \dfrac{x^6-x}{4y}.

We have to solve it for x= -4 and y = 4.

Now putting the value of x and y we get,

\dfrac{x^6-x}{4y}=\dfrac{(-4)^6-(-4)}{4}

\dfrac{x^6-x}{4y}=\dfrac{4096+4}{4}

\dfrac{x^6-x}{4y}=1250

Hence the value of given expression when x=-4 and y=4 is 1250.

The florida manatee population is 3,000 and is decreasing by 11% each year. Write a function for this situation.
True [87]

Answer:

P=3000(0.89)^t

Step-by-step explanation:

It was given that, florida manatee population is 3,000 and is decreasing by 11% each year.

We want to write a function for this situation.

Since the population is decreasing annually, it is modelled by:

P=P_0(1-r\%)^t

We substitute the give initial population and rate of decrease to get:

P=3000(1-0.11)^t

This simplifies to:

P=3000(0.89)^t
