a circle centered at the origin contains the point (0,-9). does (8, square root 17) also lie on the circle? explain.
belka [17]

Answer:

Yes

Step-by-step explanation:

The radius of the circle is 9. If we imagine the distance to (8,  sqrt 17) as a right triangle, where one leg is 8 and the other is square root 17, we can use the Pythagorean formula to solve this

8^2 (64) + sqrt 17^2 (17)= c^2

81=c^c

9=c

we can see that since the radius to the origin is 9, this point indeed lies on the circle.

Describe in detail two different real-world situations in which you could use the Pythagorean Theorem.
omeli [17]

Answer:

you can use it in architecture and construction

Step-by-step explanation:

say you are building a sloped roof. If you know the height of the roof and the length for it to cover, you can use the Pythagorean Theorem to find the diagonal length of the roof's slope. You can use this information to cut properly sized beams to support the roof, or calculate the area of the roof that you would need to shingle. I hope this helps!

The length of a rectangle is increasing at a rate of 9 cm/s and its width is increasing at a rate of 7 cm/s. When the length is
Hunter-Best [27]

Answer:

<em>129 </em>cm^2/s

Step-by-step explanation:

Increasing rate of length, \frac{dl}{dt}= 9 cm/s

Increasing rate of width, \frac{dw}{dt} = 7 cm/s

Length, l = 12 cm

Width, w = 5 cm

To find:

Rate of increase of area of rectangle at above given points.

Solution:

Formula for area of a rectangle is given as:

Area = Length \times Width

OR

A = l \times w

Differentiating w.r.to t:

\dfrac{d}{dt}A = \dfrac{d}{dt}(l \times w)\\\Rightarrow \dfrac{d}{dt}A = w \times \dfrac{d}{dt}l +l \times \dfrac{d}{dt}w

Putting the values:

\Rightarrow \dfrac{dA}{dt} = 5 \times 9 + 12 \times 7\\\Rightarrow \dfrac{dA}{dt} = 45 + 84\\\Rightarrow \bold{\dfrac{dA}{dt} = 129\ cm^2/sec}

Sylvio loaned a friend $1500 at a simple annual interest rate of 5%. How many years did it take Sylvio’s friend to repay him if
olchik [2.2K]

Answer:

Option B. 3 years.

Step-by-step explanation:

Sylvio loaned a friend $1,500 at a simple annual interest rate of 5%.

Formula of simple interest = I = P(rt)

I = Interest ($225)

P = Principal amount ( $1,500)

r = 5% = 0.05

t = time ( ? )

Now put the values to find the years.

225 = 1500( 0.05t)

225 = 75t

75t = 225

t =  

t = 3

It will take 3 years to repay him if Sylvio earned $225 in interest.
