Answer:Ok, we have:

d(t) = 3*t^2 + 5*t - 2.

The first interval is:

(2, 3)

and remember that, for an interval (a,b), the difference quotient is:

D = (f(b) - f(a))/(b -a)

Then in this first interval we have:

So the average rate of change in (2,3) is 20.

now, in (2, 2.5) we have:

So here the rate of change is 9.25

And in the interval (2, 2.1) we have:

So in this interval the rate of change is 1.73

Step-by-step explanation: hope this helps luvv

Which number line represents the solution set for the inequality 2x- 6>6 (x-2)+8

kirill [66]

Answer:

The inequality is

2 x - 6 > 6(x -2) +8

To solve the inequality we will first use distributive property with respect to multiplication over subtraction

And then bring constant on one side and variable on another side keeping the inequality maintained

2 x -6 > 6 x -12 + 8

2 x -6 > 6 x - 4

6 x - 2 x< -6+4

4 x < -2

Dividing both sides by 2

x < $\frac{-1}{2}$

Now i will draw the graph of above function.

Answer:

Step-by-step explanation:

Probability of getting 9 or 11 = 2 /6 =1/3

Probability of getting tails in coin = 1/ 2

Probability of getting 9 or 11 AND tails in coin toss = 1/2 * 1/3

= 1/6

natita [175]

Answer:

A reasonable estimate of the probability is equal to $0.1389$ or $13.89\%$

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y-----> size of the sample space

$P=\frac{x}{y}$

In this problem we have

$x=15$

$y=108$

substitute

$P=\frac{15}{108}=0.1389$

Convert to percentage

$0.1389*100=13.89\%$
