Mathematics

Answer:

  x = 21

Step-by-step explanation:

From the rules of secants (and tangents), you know that ...

   x^2 = 7·(7 +56)

   x = √(7·63) = √441 = 21

_____

When secant lines intersect, the product of distances from the point of intersection to the two points on the circle is a constant. The tangent line is a degenerate case where the two points of intersection are the same point (hence the product of distances is x^2). For the other secant, the near distance is 7, and the far distance is 7+56  = 63.

Interestingly, this property holds whether the secants intersect inside the circle or outside (as here). That makes it easier to remember, since there's really only one rule, not three.

Nafessa graphs a line with slope 5 that passes through the point (3,-2).
Zina [86]
We know m = 5, x = 3, and y = -2, and that the point slope form is y = mx + b, so plugging these in we can solve for b;

-2 = 5 * 3 + b

-2 = 15 + b

b = -17

So the equation for the line would be;

y = 5x - 17

b is the y intercept, so that is answered (0,-17), to solve for the x intercept you have to plug 0 in for y in the equation, so;

0 = 5x - 17

17 = 5x

x = 17/5

So the x intercept would be (17/5,0)

Can someone help me evaluate this?
yawa3891 [41]

Answer:

\frac{4}{9}

Step-by-step explanation:

So first rewrite the inside of the parentheses as improper fractions:

\frac{8}{9} ÷ (\frac{25}{4}*\frac{16}{5}-18)

Now simplify the inside:

\frac{8}{9} ÷ 2

Which is:

\frac{8}{18}=\frac{4}{9}

What are the domain and range of the function on the graph? The domain includes all integers, and the range is y ≥ 0. The domain
Lisa [10]

Answer:

The domain of the function i.e. the value of x can be any real number and the range of the function is y > 0.

Step-by-step explanation:

On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and curves up and increases in quadrant 1.

Therefore, as x tends to - ∞, the y-value tends to 0 but not equal to zero and as x tends to +∞, the y-value also tends to +∞.

Hence, the domain of the function i.e. the value of x can be any real number and the range of the function is y > 0. (Answer)
