Answer: About 3.06

Step-by-step explanation:

  We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

  Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

      cos(θ) = \frac{adjacent}{hypotenuse }

      cos(40) = \frac{x}{4}

      0.766 ≈ \frac{x}{4}

      3.06 ≈ x

      x ≈ 3.06

A sequence is defined by the formula f(n+1)=f(n)-3. If f(4)=22, what is f(1)?
Vlad [161]
<h3>Answer: Choice C) 31</h3>

==============================================

Explanation:

The recursive rule

f(n+1)=f(n)-3

can be rearranged to

f(n) = f(n+1)+3

after adding 3 to both sides

----------------

Now let's say we plug in n = 3

f(n) = f(n+1)+3

f(3) = f(3+1)+3

f(3) = f(4)+3

f(3) = 22+3

f(3) = 25

Repeat for n = 2

f(n) = f(n+1)+3

f(2) = f(2+1)+3

f(2) = f(3)+3

f(2) = 25+3

f(2) = 28

Each time we keep adding 3 to get the previous term (since the original recursive rule says to subtract 3 to get the next term; we just go backwards of what the instructions say).

Lastly, we can find that f(1) = f(2)+3 = 28+3 = 31 making the answer to be choice C.

In a sample of 100 randomly selected concert attendees, the concert organizers find that 11 of them left the show early. The con
3241004551 [841]

Answer:

A) ≈22.4 concert attendees might have left early.

B) 605 attendees might leave early.

Step-by-step explanation:

A) 11/100, or 11%, of the sample left early.

    11% of all the concert attendees is (11/100) × 2040 ≅ 22.4

    attendees who might have left early.

B) 11% of the total attendance is 11% × 5500 = 605 attendees who might

    leave early.

Please helpppppp mee thanks everyone ​
netineya [11]

Answer:

\frac{32}{35}

Step-by-step explanation:

To answer this question you need to get the same denominator (bottom number of a fraction ) on both values

Because 7 is a factor of 35, you can multiply the whole fraction by 5, (so that the first fraction has a denominator of 35 which is the same as the other value)

\frac{4}{7}×5= \frac{20}{35}

then you add them up but remember if the denominator is the same you do <u>not </u> add them.

\frac{20}{35} +\frac{12}{35} = \frac{32}{35}

Hope the answer is right, Ask if unsure :)
