Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.

Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:

r= 10 ft

Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
= 2(π)(10)
= 20π ft
Answer:
1.85
Step-by-step explanation:
equation will be 10(h+1.75)=36
hamburger price is $1.85
Its like x² + 4x +20 = 0,
x = [-4 + √[(4²) - (4*1*20)]]/(2*1) = [-4 + √(16-80)]/2 = [-4 + √(-64)]/2 = [-4 + 8√(-1)]/2 = -2 + 4i,
x = [-4 - √[(4²) - (4*1*20)]]/(2*1) = [-4 - √(16-80)]/2 = [-4 - √(-64)]/2 = [-4 - 8√(-1)]/2 = -2 - 4i,
here i = √(-1), its a complex number.
so solution is a complex number,
x = -2 - 4i & -2 + 4i.
Step-by-step explanation:
When a factor appears in both the numerator and denominator, that is a hole in the function.
Therefore, the domain of h(x) is (-∞, 4) (4, ∞).
Which means the range of h(x) is (-∞, 5) (5, ∞).
