Answer:
The glass can hold 8. (I think)
Step-by-step explanation:
I will do 9 only. You can do 11.
Question 9
sin(60) = x/8
sin(60)(8) = x
4•sqrt{3} = x
x^2 + y^2 = 8^2
(4•sqrt{3})^2 + y^2 = 64
16(3) + y^2 = 64
48 + y^2 = 64
y^2 = 64 - 48
y^2 = 16
sqrt{y^2} = sqrt{16}
y = 4
Do 11 the same way.
Question:
13 + b > 34
<em>Step 1: Keep variable on one side, and subtract 13 on both sides.</em>
b > 21
<em>Step 2: Now that you have the value of b, create a number line that includes the number "21"</em>
<em />
<em>Step 3: Since it is not "or equal too" we will use an open dot, since we do not contain that point. Put dot over 21. </em>
<em />
<em>Step 4: The sign is ( > ) meaning greater than. Therefore all points greater than 21 is </em><em>true</em><em>. See graph. </em>

Inupt values for y and evaluate to get y values
(x,y)
if x=0
y=3(0)-1
y=0-1
y=-1
(0,-1)
if x=1
y=3(1)-1
y=3-1
y=2
(1,2)
if x=2
y=3(2)-1
y=6-1
y=5
(2,5)
if x=3
y=3(3)-1
y=9-1
y=8
(3,8)
look for the points
(0,-1) (1,2) (2,5) (3,8)
B
