Answer:

78.54 ft²

Step-by-step explanation:

Hello!

The formula for the area of a circle is A = πr², where r is the radius.

Given r is 5, find the area:

A = πr²
A = π*5²
A = 25π
A = 78.5398163397 ≈ 78.54

The area is 78.54 ft²

If theres 3 apples and you take 2 away, how many do you have?

Degger [83]

The answer depends on the perspective; however, this question is often meant to be a "trick question"; with the answer being: 2 (two) apples!
_______________________________________________
The rationale behind this answer is that if there are three apples, but you "take 2 away" you now have "2" apples, because YOU are the one who "took away the 2 apples"—so presumably, YOU have the "2 apples" that YOU "took away"!

Answer:

$\sqrt{\frac{9}{4}}$ < $\frac{5}{3}$ < $\sqrt{5}$ < 2.5

Step-by-step explanation:

Given the following numbers, $\sqrt{\frac{9}{4}}, \sqrt{5}, 2.5, and, \frac{5}{3}$ , let's express each as whole or decimal numbers, to find out the least to the greatest.

$\sqrt{\frac{9}{4}} = \frac{\sqrt{9}}{\sqrt{4}}$

$\frac{3}{2} = 1.5$

$\sqrt{5}$ ≈ 2.2

2.5 (already in decimal form)

$\frac{5}{3}$ ≈ 1.7

From the least to the greatest, we have:

$\sqrt{\frac{9}{4}}$ < $\frac{5}{3}$ < $\sqrt{5}$ < 2.5

PLZ NEED A PROFESSIONAL :( Which is the equation of a parabola with a directrix at y = 2 and a focus at (5, 0)

inysia [295]

Answer:

Answer D (the fourth one)

Step-by-step explanation:

First, we need to set up a (y−k)^2=4p(x−h). After plugging in all of your values, you would get (x-5)^2=-4(y-1). Now, we need to solve in terms of y by dividing each side by the factors that don't contain the variable. Your final solution should be $y = -\frac{1}{4}(x - 5^{2}) + 1$
