Area formula is A=πr2 
A=3.1416(radius)2 (radius is 7)
A=3.1416(49) 
A=153.94 
The area is 153.94 inches.
Hope that was helpful :)

The number of new visits to a website is decreasing exponentially. It can be modeled by the function h(d)=2170(0.92)^d, where h
In-s [12.5K]

Answer:

2) -141 hits/da  

Step-by-step explanation:

Calculate the values of h(2) and h(4)

h(2) = 2170(0.92)² = 2170 × 0.8464 = 1837

h(4) = 2170(0.92)⁴ = 2170 × 0.7164 = 1555

Calculate the average rate of change

Rate of change = (y₂ - y₁)/(x₂-x₁) = (1555 -1837)/(4 - 2) = -282/2 = -141 hits/da

The average rate of change is -141 hits/da.

In the figure below, the red curve represents the function h(d), while the green dashed line represents the average rate of change over the interval 2 ≤ d ≤4.

Given g of x equals cube root of the quantity x plus 6, on what interval is the function negative?
nikdorinn [45]

The interval for the function to be negative will be (-∞<x<-7).

<h3>What is a function?</h3>

A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.

Here we have a function:-

g(x) = ∛(x+6)

If we put the value of x lesser than 6 in the function we will always get a negative value so the interval will be:-

(-∞<x<-7).

Therefore interval for the function to be negative will be (-∞<x<-7).
