Answer:

6.5 cm

Step-by-step explanation:

Here, the tangent line squared is equal to the secant line times the secant line outside the circle.

That is 20.2² = 14.7 * (14.7 + 2x) --> it is 2x because the secant goes through the whole circle.

Simplify: 408.04 = 216.09 + 29.4x

Subtract: 191.95 = 29.4x

Divide: x = 6.528911565 ≈ 6.5 cm

The second term in a geometric sequence is 20. The fourth term in the same sequence is 45/4, or 11.25. What is the common ratio

Elanso [62]

We use equations for geometric sequence. We do as follows:

a(n) = a(1) r^(n-1)
20 = ar^(2-1)
20 = ar
a = 20/r

11.25= ar^(4-1)
11.25 = ar^3
11.25 = (20/r)r^3
r = 0.75

Hope this answers the question. Have a nice day.

Mixed numbers have both fractions and _____ numbers.

Vladimir [108]

Answer:

"Whole"

Step-by-step explanation:

A mixed number is made out of two parts: the fraction and the whole number.

Other material would say that a mixed number has three parts: the numerator, denominator, and the whole number. This is also correct, as the numerator and denominator make up the fraction in the mixed number.

The fraction is the 'incomplete' part of the mixed number, and the whole number is the 'complete' part of the mixed number.

For example:

$3.25 = 3\frac{1}{4}$

0.25 = 1/4

3.00 = 3

"Whole" should fill in the blank and make the statement true.
