The correct answer would be A
Anon25 [30]4 years ago
6 0

Answer:

The answer is A

Step-by-step explanation:

A * 2 = 1/2πr^2 * 2

2A / π = πr^2 / π

\sqrt{\frac{2a}{\pi } }= \sqrt{r^2}

So, the answer is A because r = \sqrt{\frac{2a}{\pi } }

Find the equation for the line that passes through the points and . State your
gavmur [86]

Answer:

y = 2x.

Step-by-step explanation:

The slope = (6 - (-4))/(3 - (-2))

= (6 + 4)/(3+2)

= 10/5

= 2.

Using this and the point (3, 6) we have:

y - 6 = 2(x - 3)

y = 2x - 6 + 6

y = 2x.

Varvara68 [4.7K]

Answer:  B: 0.81 miles

Step-by-step explanation:

The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

The formula for this is: a^2 + b^2 = c^2

So let the first side or a be .19

and the second side be .28

and now we are looking for c which is the missing side

.19^2 + .28^2 = c^20.0361 + 0.784 = .1145

get the square root of .1145

√.1145 = it is approximately 0.34

get the total distance by adding three sides

= .34 + .19 + .28

= 0.81

Solving Quadratic Equations posttest <br><br> A.<br> B.<br> C.<br> D.
beks73 [17]

Answer:

D. x = 3 \pm \sqrt{10}

Step-by-step explanation:

x^2 - 6x - 1 = 0

x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}

a = 1; b = -6; c = -1

x = \dfrac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(-1)}}{2(1)}

x = \dfrac{6 \pm \sqrt{36 + 4}}{2}

x = \dfrac{6 \pm \sqrt{40}}{2}

x = \dfrac{6 \pm \sqrt{4 \times 10}}{2}

x = \dfrac{6 \pm 2 \sqrt{10}}{2}

x = 3 \pm \sqrt{10}
