Find x Round to the nearest tenth
nikdorinn [45]

Answer:

15.5

Step-by-step explanation:

So the formula here is the square of the tangent length is equal to the product of the exterior part of the secant line and total length of the secant.

So that means we have x^2=10(14+10).

After simplifying the right hand side we have the equation is x^2=10(24) or x^2=240.

To get rid of the square on the x, we square root both sides.

x=sqrt(240)

x=15.49193338

To the nearest tenths, the answer is x=15.5

So 15.5 inches is the length of x.

Suppose Z denotes the set of all integers, Z denotes the set of all positive integers, and Z− denotes the set of all negative in
ikadub [295]

Answer:

a) False

b) False

Step-by-step explanation:

We are given the following information:

Z is a set of all integers, Z^+ is a set of all positive integers and  Z^- is a set of all negative integers.

Q is a set of all rational numbers, Q^+ is a set of all positive rational numbers and Q^- is a set of all negative rational numbers.

N is a set of all natural numbers.

a) False

We will show this with the help of a counter example.

Z = 3\\Q = \frac{3}{4}\\\displaystyle\frac{Z}{Q} = \displaystyle\frac{3}{\frac{3}{4}} = \displaystyle\frac{8}{3}

which is a rational number and not an integer.

b) False

We will show this with the help of a counter example.

Z = 3\\Z^- = -5\\\displaystyle\frac{Z}{Z^-} = \displaystyle\frac{3}{-5} = -\displaystyle\frac{3}{5}

which is a rational number and not a natural number.

Sedaia [141]

Answer:

Step-by-step explanation:

28x^3 = 2 * 2 * 7 * x * x * x

16x^2Y^2 = 2 * 2 * 2 * 2 * x * x * y *y

GCF = 2 * 2 * x *x = 4x^2
