Since F(X) = 3^X,
F(4) = 3^4 = 81
Answer:
She needs to purchase 50 square feet of wood .
Step-by-step explanation:
we can find the number of square feet of wood needed to purchase by finding the area of the table
The area of the table = area of the triangle + area of the rectangle
Area of the triangle:
Area of the triangle = 
On substituting the values from the attached figure , we get
Area of the triangle = 
Area of the triangle = 
Area of the triangle = 10 square feet
Area of the rectangle:
Area of the rectangle = Length X Breadth
On substituting the values from the attached figure , we get
Area of the triangle = 
Area of the triangle = 40 square feet
Thus the area of the table = 10 + 40 = 50 square feet
Float
because the water weighs more so it will hold it.
Answer:
70
Step-by-step explanation:
7^2 - ( 6-3^3)
PEMDAS
Parentheses first
7^2 - ( 6-3^3)
The exponent in the parentheses first
7^2 - ( 6-27)
7^2 - ( -21)
Now the exponent
49 - (-21)
Now subtract
49 +21
70
