Answer:
The length of one lap of the track would be about 377 feet
Step-by-step explanation:
- The length of any circular path is equal to the circumference of the circular path
- The circumference of a circle C = π d, where d is the lengths of its diameter
∵ A circular race track has a diameter of 120 feet
→ That means the length of each lap equal the circumference of the track
∴ The length of one lap = C
∵ The diameter of the track is 120 feet
∴ d = 120 feet
∵ C = πd
∴ C = π(120)
→ Use π = 3.141
∴ C = (3.141)(120)
∴ C = 376.92 feet
→ Round it to the nearest whole number
∴ C ≅ 377 feet
∴ The length of one lap of the track would be about 377 feet

Answer:
Step-by-step explanation:
So 1 is infinite solutions, because -32.4 is equal to -32.4 no matter what you do to it now, because adding, subtracting, whatever will not change teh fact that these are equal because the stuff has to be done on both sides. the solutions for this are INFINITE.
Answer:
Value of x is, 8
Step-by-step explanation:
Given: ,.....[1]
To find the value of x:
Using exponent rules:
Taking square both sides in [1] we have;
Simplify:
or
Multiply both sides by we get;
Simplify:
or
Simplify:
x = 8
Therefore, the value of x is, 8
B. f(x) = 3(0.7)ˣ
Decay means an overall decrease in the original value. Exponential equations are written in the form:
amount after time n = original amount x (decay OR increase factor)ⁿ
The value of the factor is less than one in the case of a decay.
