A 2-column table with 6 rows. First column is labeled Beat number with entries 2, 3, 4, 5, 6, 7. Second column is labeled Note Frequency (Hertz) with entries 261.6, 392.0, 392.0, 444.0, 444.0, 392.0. Use the information from the table to describe the relationship between musical frequency of notes and the beats in a tune. The musical frequency of notes is decreasing between beat numbers and .

b. x + 1

step-by-step explanation:

i'am smart

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
