Use the information in the diagram to find the length of segment AD. Round your answer to the nearest hundredth.
Lana71 [14]

Based on the lengths of the given triangles and the length of segment BD, the length of segment AD is 22.20.

<h3>What is the length of segment AD?</h3>

The triangle ABC is a right angled triangle with segment AB being the hypothenuse.

We can therefore find this length using the Pythagoras Rule:

Hypothenuse ² = a² + b²

Hypothenuse ² = 28.6² + 23.2²

Hypothenuse ² = 1,356.20

Hypothenuse = √1,356.20

= 36.83

Length of AD:
= AB - BD

= 36.83 - 14.60

= 22.2

¿Cuál de los siguientes puntos no pertenece a la función cuadrática f(x) = 1-x^2 ?
dusya [7]

Answer:

<h2>A. (0,1)</h2>

Step-by-step explanation:

The question lacks the e=required option. Find the complete question below with options.

Which of the following points does not belong to the quadratic function

f(x) = 1-x²?

a.(0,1) b.(1,0) c.(-1,0)

Let f(x) = 0

The equation becomes 1-x² = 0

Solving 1-x² = 0 for x;

subtract 1 from both sides;

1-x²-1 = 0-1

-x² = -1

multiply both sides by minus sign

-(-x²) = -(-1)

x² = 1

take square root of both sides;

√x² = ±√1

x = ±1

x = 1 and x = -1

when x = 1

f(x) = y = 1-1²

y = 1-1

y = 0

when x = -1

f(x) = y = 1-(-1)²

y = 1-1

y = 0

Hence the coordinate of the function f(x) = 1-x² are (±1, 0) i.e (1, 0) and (-1, 0). The point that does not belong to the quadratic function is (0, 1)

I need 33. B) find the exact time when the radius reaches 10 inches<br><br> 100 points! Plz help
stealth61 [152]

Step-by-step explanation:

You have found a function r(V(t)). We can see that this function is a one variable function. The variable is time.

So in this specific function we can call r(v(t)), r(t).

So:

r(t) =  \sqrt[3]{ \frac{3 \times (10 + 20t)}{4\pi} }

If α is the moment that the radius is 10 inches and since the function above gives radius in inches we have to solve the equation:

r( \alpha ) = 10

Which is the same as:

\sqrt[3]{ \frac{3 \times (10 + 20 \alpha )}{4\pi} }  = 10 \\  \frac{3 \times (10 + 20 \alpha )}{4\pi}  = 1000 \\ (10 + 20 \alpha ) =  \frac{4000\pi}{3}  \\ 20 \alpha  =  \frac{(4000\pi - 30)}{3} \\  \alpha  =  \frac{(4000\pi - 30)}{60}

How many times does a dragonfly's wing beat per minute
marshall27 [118]
<span>A dragonfly beats its wings about 30 times a second. This is necessary to allow the insect to keep itself airborne, due to the relative weight of its body. Luckily, dragonflies have two sets of wings, or they would have to work even harder to stay up in the air.</span>
