Answer:
x=9,-1 and 
Explanation:
we have been given with the quadratic equation 
we compare the given quadratic equation with general quadratic equation
general quadratic is 
from given quadratic equation a=1,b= -8,c= -9
substituting these values in the formula for discriminant 

Now, to find the value of x
Formula is 
Now, substituting the values we will get

And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of

Answer:
Only table C shows proportional relationship
Step by Step Explanation:
Given
Tables A, B an C
Required
Which table shows proportional relationship?
In table A .
x = 2 and y = 20
k = 20/2
k = 10
Also, x = 12, y = 132
k =. 132/12.
k = 11
Both values of k are not equal.
Hence, the table is not proportional
In table B
x = 5 and y = 20
k = 20/5
k = 4
Also, x = 7, y = 30
k =. 30/7
k = 4.29
Both values of k are not equal.
Hence, the table is not proportional
In table C
x = 9 and y = 90
k = 90/9
k = 10
Also, x = 14, y = 140
k =. 140/14
k = 10
Also, x = 24, y = 240
k =. 240/24
k = 10
All values of k are equal.
Hence, the table is proportional

<h3><u>Given</u><u> </u><u>Information</u><u>:</u></h3>
- <u>Diameter of can</u>:- 3.6 cm
- <u>Height of</u><u> </u><u>can</u><u>:</u><u>-</u> 6.4 cm
<h3><u>To</u><u> </u><u>Find</u><u> </u><u>Out</u><u>:</u></h3>
- <u>Volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>Can</u><u>.</u>
<h3><u>Solution</u><u>:</u></h3>
Radius = (Diameter/2)
ㅤㅤㅤㅤ3.6 cm/2
ㅤㅤㅤㅤ1.8 cm
<u>So</u><u>,</u><u> </u><u>Radius</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>soup</u><u> </u><u>can</u><u> </u><u>is</u> 1.8 cm.
Volume øf cylinder = Volume øf can
Volume of cylinder = π r²h
(π = 22/7)
(r = radius = 1.8 cm)
(h = height = 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7×(1.8 cm)²× 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7× 3.24 cm² × 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7 × 20.736 cm³
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= (456.192/7) cm³
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 65.17 cm³
So, the Volume of the soup can is 65.17 cm³

With each gallon you need 11 gallons with 2 parts red 9 parts yellow and since 11x4= 44 you need to do this 4 times
4x2(red)= 8
4x9(yellow)=36
36+8=44
basically 8 gallons of red
i hope this made sense
Answer:
0.078125.
Step-by-step explanation:
This is a geometric sequence with first term a1 = 20 and common ratio r = 10/20 = 5/10 = 0.5.
nth term = a1 r^(n -1) so here:
9th term = 20(0.5)^(9-1)
= 20(0.5)^8
= 0.078125.
