An inscribed triangle with the hypotenuse being the diameter of the circle has angle A be 42 degrees. Angle C is 90 degrees. The
eduard

Answer:

The Radius of circle is 7.15 cm  

Step-by-step explanation:

Given as :

A Triangle is inscribed into circle

The center of circle is O

The Diameter of circle = AK = d

The hypotenuse of triangle being the diameter of circle

The Area of triangle = 50 cm²

Let The radius of circle = r cm

The Triangle is right angle at c

So , ∠ACK = 90°

∠CAK = 42°

∠AKC = 180° - (90° + 42°)

So, ∠AKC = 48°

Now, ∵ Area of triangle ACK = 50 cm²

So, \dfrac{1}{2} × AC × CK = 50

Or, AC × CK = 50 × 2

i.e , AC × CK = 100        ..........1

From figure

Sin 48° =  \dfrac{AC}{AK}

Or, 0.74 =  \dfrac{AC}{d}

∴ AC = 0.74 d             ..........2

<u>Similarly</u>

Sin 42° =  \dfrac{CK}{AK}

Or, 0.66 =  \dfrac{CK}{d}

∴ CK = 0.66 d               .............3

<u>Putting eq 2 and 3 value into eq 1</u>

i.e  AC × CK = 100  

Or, 0.74 d  × 0.66 d = 100  

Or, 0.4884 × d² = 100  

∴ d² = \dfrac{100}{0.4884}

Or, d² = 204.75

Or, d = \sqrt{204.75}

Or, d = 14.30

So, The diameter of circle = d = 14.30 cm

Now, Radius of circle = \dfrac{\textrm diameter}{2}

Or, r =  \dfrac{\textrm 14.30 cm}{2}

i.e r = 7.15 cm

So, The Radius of circle =  r = 7.15 cm

Hence, The Radius of circle is 7.15 cm  Answer

Scientist released 5 foxes into a new habitat in year 0. Each year, there were four times as many foxes as the year before. How
prisoha [69]

Answer:

The function that this scenario represents is:

P(x) = 5(4) ^ x

Step-by-step explanation:

The initial number of foxes was 5. The following year they had

year 1: 5 * (4) = 20 foxes

year 2: 5 * 4 * (4) = 80 foxes

year 3: 5 * 4 * 4 * (4) = 320 foxes

year x: 5 * 4 ^ x foxes

Then the equation that models the situation is an equation of exponential growth. Where P(x) is the population of foxes in year x.

So:

P(x) = 5(4) ^ x

Write an equation off the line that passes through the point -4 -3 and is parallel to 4 y- X=- 16
ycow [4]
Parallel lines on a graph need to have the same slope. So if you put 4y-x=-16 is slope-int form, you get y=1/4x-4. Now, you have to make another equation like this. So since you know that the slope has to be 1/4, the start of the equation for a line that passes (-4,-3) is y=1/4x. Now, When you plug in -4 is in the x, you get 1/4(-4)=-3. However, -1=-3 is not true. So, what do you add or subtract to -1 to get -3? You get -2, which is the y-intercept in the slope-int form, mx+b. So for your final equation, you get y=1/4x-2
