Domain is what can be put into the function to make it work
Considering that there are no numbers that 3x^2 cannot handle then the domain is all real numbers
Answer:
10 units
Step-by-step explanation:
Area of the triangle (A') = 1/2bh
A' = 1/2bh............ Equation 1
Where b = base of the triangle, h = height of the triangle
From the diagram,
Given: b = 12.5 unit, h = 4 unit
Substitute into equation 1
A' = 1/2(12.5)(4)
A' = 25 squared unit.
Also,
Area of the rectangle (A) = Lenght(L)×width(w)
A = Lw............ Equation 2
From the question,
If the area of the rectangle is 40% larger than the area of the triangle
Therefore,
A = 1.4A'
A = 1.4(25)
A = 35 squared unit.
Also given: w = 3
= 7/2
Substitute into equation 2
35 = L×7/2
7L = 35×2
7L = 70
L = 70/7
L = 10 units
Answer:
$4,500
Step-by-step explanation:
For simple interest,
I = prt,
where
I = interest
p = principal
r = annual interest rate
t = number of years
We have p = $5,000, r = 9% = 0.09; t = 1 year
I = $5,000 × 0.09 × 1
I = $450
