Answer:
The coordinates of point Q are 
Step-by-step explanation:
The coordinates of point Q can be found looking at the graph
We need to find the value of x-coordinate and y-coordinate by looking at graph.
Check the value of x-coordinate that matches point Q similarly check the value of y-coordinate that matches point Q
Looking at the graph Point Q is at x=4 and y=2.5 or 
So, The coordinates of point Q are 
Answer:
13
Step-by-step explanation:
Given x = 2, y = 3 and z = 4. We'll evaluate the value of x² + y² with given condition.
First, remind that we are only given the expression of x-term and y-term only and therefore, z-term is not included - it's not to be considered.
Substitute x = 2 and y = 3 in the expression:

Hence, the value of x² + y² when x = 2 and y = 3 is 13.

Answer:
V = 2010.6193m^3
Step-by-step explanation:
This is right assuming 8m is the radius and 10m is the height
The area of the trapezoid is 43.5 inches²
Step-by-step explanation:
The formula of the area of a trapezoid is
, where:
and
are the two parallel bases- h is its height
∵
=
feet
∵
= 14 inches
∵ h = 3 inches
- Change the length of
from feet to inches
∵ 1 foot = 12 inches
∴
feet =
× 12 = 15 inches
∴
= 15 inches
Substitute the values of
,
and h in the
formula of the area
∴ 
∴ A = 43.5 inches²
The area of the trapezoid is 43.5 inches²
