Answer:
If the units in the equation are in feet, it lef5t at a height of 7.4 feet (or meters, etc.).
Step-by-step explanation:
p(x) = - 0.013x2 + 0.02x + 7.4
When x, the time, = 0 [just before it leaves the pitcher's hand]
p(0) = 7.4
Answer:
Option A. (6,2)
Step-by-step explanation:
We have the following inequality:

Solving for y we have:

The line that limits the region of inequality is

Then the region of inequality are all values of y that are less than 
In other words, the points belonging to the inequality are all those that lie below the line.
To find out which point belongs to this region substitute inequality and observe if it is satisfied
A. (6,2)

<em> is satisfied</em>
B. (2, 6)

<em>it is not satisfied</em>
C. (2, -1)

it is not satisfied
<em>The answer is the option A</em>
For this case we have that by definition of trigonometric relations that the sine of an angle is equal to the opposite leg to the angle on the hypotenuse. That is to say:

Clearing the value of "a":

Rounding off we have:
17.7
Answer:
Option B
Answer:

Step-by-step explanation:
The problem can be modeled by using the compound growth formula.
Given, Initial number P_0 of people who Nicholas sent the chain letter t=50
The growth rate, r =99%=0.99
Period of Growth,k =12 Weeks

Therefore, in any week (t) after Nicholas initially sent the mail, the number of people who receive the email is modeled by the function:
