Find the circumference of a circle with an area of 615.75 square inches.

A=pie×radius squared is the area formula of a circle. The circumference formula or a circle is C=pie×diameter. 615.75=(3.14)(radius) squared. Divide both sides by the 3.14. What ever 615.75 divided by 3.14 is-is radius squared. The square root is your radius. The radius is half the diameter, so double what you have right now as the radius to get the diameter. Now since C=pie×diameter, your circumference is your pie×your diameter. Whatever your answer is-is your circumference.

A function, f(x) = 4x + 5, has a domain 0 < x < 50. What is its range?

Roman55 [17]

Answer:

f(x) = 4x+5 ; 0 ≤ x ≤ 50

The range is the possible output values of f(x)

4(0) + 5 = 5 smallest output value in range

4(50) + 5 = 55 largest output value in range

The outputs are between 5 and 55 including the endpoints so

the range is [5, 55]

F(x)=8x^2-2x+3<br> g(x)=12x^2+4x-3<br> what is h(x)=f(x)-g(x)?

Trava [24]

Answer: $h(x)=-4x^2-6x+6$

Step-by-step explanation:

To find the function h(x), you need to subtract the function $f(x)=8x^2-2x+3$ and the function $g(x)=12x^2+4x-3$ .

$h(x)=f(x)-g(x)\\h(x)=8x^2-2x+3-(12x^2+4x-3)$

Distribute the negative sign:

$h(x)=8x^2-2x+3-12x^2-4x+3$

Now you can add the like terms:

$h(x)=-4x^2-6x+6$

Therefore, you get that the function h(x) is:

$h(x)=-4x^2-6x+6$
