First you need to find out how many inches are in a yard. After that, times that by 2 1/4 or use the improper fraction form 9/4 which I am going to use.
We know there is 36 in = 1yd
36 x 9/4 = 324 / 4
324 / 4 = 81 inches
Answer:
approx. 23

Answer:
$
Step-by-step explanation:
Let's assume 
represents the number of pounds of fruit.
We need to multiply the number of pounds of fruit by the cost per pound.
This is $
, or in a simpler form, $.
4 is the proportion because 8 + 4 is 12 then keep adding 12 + 4 = 16 + 4 = 20 So that mean it is proportional I hope that helps.
Answer:
Step-by-step explanation:
<h3>Given</h3>
<u>Quadratic function </u>
with the roots:
<h3>To find </h3>
<h3>Solution</h3>
<u>As we know the sum of the roots is -b/a and the product of the roots is c/a. Substituting values and solving for b and c:</u>
- (-5 + 9i) + (-5 - 9i) = -b/-1
- -10 = b
- b = -10
And
- (-5 + 9i)(-5 - 9i) = c/-1
- (-5)² - (9i)² = -c
- 25 - 81(-1) = -c
- - c = 25 + 81
- - c = 106
- c = -106
g(x) = -x² -10x - 106
