Find X in the figure below.

Mathematics
1 answer:
Hitman42 [59]3 years ago

<h3>Answer:</h3>

x = 3

<h3>Explanation:</h3>

The product of the lengths of segments from the intersection point to the circle is the same for both secants.

... 1×6 = 2×x

... 6/2 = x = 3 . . . . . divide by 2

_____

<em>Comment on secant geometry</em>

Interestingly, this relation is true whether the point of intersection of the secants is inside the circle or outside.

When it is outside, the product is of the distance to the near intersection with the circle and the distance to the far intersection with the circle.

it cost $3.45 to buy 3/4 lb of chopped walnuts how much would it cost to purchase 7.2 lb of walnuts ​
andreev551 [17]

Answer:

Step-by-step explanation:

$33.12

you would divide 3.45 by 3 to get 1/4, which is 1.15, then multiply that by 4 to get the cost for one pound, which is 4.6. multiply 4.6 times 7.2 to get your answer of 33.12

Please help i missed this class and have no idea how to do this!
Nadya [2.5K]

Answer:

x = -16\frac{2}{3}

Step-by-step explanation:

When there are two lines that intersect at one point, the two angles that are directly opposite each other are equal. So in this case, (6x+175) = (3x + 127)

6x + 175 = 3x + 125

6x - 3x = 125 - 175

3x = -50

x = -50 ÷ 3

x = -16\frac{2}{3}

n many population growth problems, there is an upper limit beyond which the population cannot grow. Many scientists agree that t
givi [52]

Answer:

\frac{dP}{dt} = rP(1 - \frac{P}{K}) = 0.017P(1 - \frac{P}{16})

Step-by-step explanation:

The logistic function of population growth, that is, the solution of the differential equation is as follows:

P(t) = \frac{KP_{0}e^{rt}}{K + P_{0}(e^{rt} - 1)}

We use this equation to find the value of r.

In this problem, we have that:

K = 16, P_{0} = 2, P(50) = 4

So we find the value of r.

P(t) = \frac{KP_{0}e^{rt}}{K + P_{0}(e^{rt} - 1)}

4 = \frac{16*2e^{50r}}{16 + 2*(e^{50r} - 1)}

4 = \frac{32e^{50r}}{14 + 2e^{50r}}

56 + 8e^{50r} = 32e^{50r}}

24e^{50r} = 56

e^{50r} = 2.33

Applying ln to both sides of the equality

50r = 0.8459

r = 0.017

So

The differential equation is

\frac{dP}{dt} = rP(1 - \frac{P}{K}) = 0.017P(1 - \frac{P}{16})

Please help really fast :)​
olasank [31]

Answer:

Step-by-step explanation:

The two smaller angles add up to the measure of the total angle, so

(like a lot of geometry) it is really just an Algebra 1 problem with a nice picture to go with it --->  (5x + 13°) + (3x + 33°) = 70°

8x + 46° = 70°

8x = 24°

x = 3°

There is no actual question shown, but I imagine you want one or more of the following:

x = 3°

∠ABC = 3(3°) + 33° = 9°+ 33° = 42°

∠CBD = 5(3°) + 13° = 15° + 13° = 28°

Hope this helps.
