: $24.48 per year + price * 0.85
: $36.83 per year + price * 0.75
Substitute each value into both equations as price.
A:
129.4635
129.4625
B:
98.158
101.84
C:
145.2055
143.3625
D:
155.703
152.615
A is the lowest value where the second value is lower than the first.
Answer:
300
Step-by-step explanation:
75 multiplied by 4 is 300
Simple, finding markdown, use these two formulas.
Markdown=Original-New
and
Percent Markdown= Markdown Amount/Original*100
So,
Markdown=612-450
M=162
Markdown%= 162/612*100
M%=0.2647*100
M%=26.5 (rounded)
Thus, there was a 26.5% decrease.
Answer:
f[g(x)] = 4x²+1/16
Step-by-step explanation:
We need to put g(x) into f(x).
f[g(x)] = 1/(1/2x+4)²
f[g(x)] = 1/(1/4x²+16) Solve the exponential.
f[g(x)] = 1/(1/4x²+16) Simply the fraction.
f[g(x)] = 4x²+1/16
Answer: 20 meters.
Step-by-step explanation:
The formula for calculate the area of a square is:

Where "s" is the side length of the square:
The formula for calculate the area of a rectangle is:

Where "l" is the lenght and "w" is the width.
Based on the information provided, you know the sum of the areas of the square land and the adjacent land is 600 m². This is:

Knowing that the width of the adjacent land is 10 meters:

Since the lenght of the adjacent land and the side lenght of his actual land are equal:

You can substitute this into
:

Applying the Quadratic formula, you get:

Since the side lenght cannot be negative, you can determine that this is:
