To make a positive profit p(x)>0 we need to make:

Now we solve this for x:

We have:
a = -2
b = 7
c = -3
We will use formula for quadratic equation:

We got two solutions. One is fraction other is whole number. We will not consider fraction because the amount of muffins sold must be whole number. So our solution is:
x>3
Answer:
Riley divided the number of petunia seeds by the number of begonia seeds, getting
. What you actually need to do to calculate the probability of selecting a petunia seed is divide the number of petunia seeds by the <em>total</em> number of seeds. 5 petunia seeds and 15 begonia seeds makes 20 total seeds, so you divide 5 petunia seeds by 20 total seeds to get
.
Answer:
The value of the 3 is 30,000,000.
Step-by-step explanation:
From the digit at the right, you go multiplying each element by 10 powered to a counter that starts at zero and increases at every digit. So:
Our counter is i
i = 0;
v(7) is the value of the 7

i = 1;
v(5) is the value of the 5

i = 2;
v(1) is the value of the 1

i = 3;
v(5) is the value of the 5

i = 4;
v(9) is the value of the 9

i = 5;
v(6) is the value of the 6

i = 6;
v(8) is the value of the 8

i = 7;
v(3) is the value of the 3

The value of the 3 is 30,000,000.
Answer:
<h3>The answer is 6 units</h3>
Step-by-step explanation:
The distance between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
K (5, 6) P (1, 1)
The distance from K to P is

We have the final answer as
<h3>6 units to the nearest whole number</h3>
