Answer:
3 ft
6 ft
9 ft
Step-by-step explanation:
Set up your equation;
18=x+2x+2x+3
simplify;
5x+3=18
18-3= 15
5x=15
15/5=3
x=3
Then plug everything in;
3(2)=6
3(2)+3=9
Use the formula of Axis of symmetry, i.e -b/2a and solve for x which will be your answer.
Therefore x= -16
First, we define variables:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23
Answer:
the coach did purchase 23 large hats
d. 23
Answer:
B
Step-by-step explanation:
A) supplementary angle
C) i dont really know how to explain this im sorry
D) same as above
The average value of the given function is .
According to the statement
we have given that the function f(x) and we have to find the average value of that function.
So, For this purpose, we know that the
The given function f(x) is
And now integrate this function with the limit 0 to a then
Now integrate this then
Then the value becomes according to the integration rules is:
Now put the limits then answer will become as output is:
Now solve this equation then
Now
This is the value which represent the average of the given function in the statement.
So, The average value of the given function is .
