The number 1.3,1/1/3,1.34 in least to greatest
elixir [45]
1.3, 1 1/3, 1.34

The decimal version of 1 1/3 is 1.333 (so on)

so 1.3 is less than 1.333 and 1.333 is less than 1.34

1.3<1.333<1.34

I’m working on 3 and 4 only maybe if I can have some explanation so I can understand and do more of these next week.
guapka [62]

4.b.

Answer:  See below.

Step-by-step explanation:

<h2><u>For the equation f(x) = 2x</u></h2>

3.a.  f(6) means use x = 6 in the equation f(x) = 2x

so f(6) would be f(6)= 2(6)

<u>f(6) = 12</u>

3.b.  f(-11) = 2(-11)

<u>f(-11) = -22</u>

3.c.  f(2.75) = 2(2.75)

<u>f(2.75) = 5.5</u>

3.d.  This is turned around.  We are told f(x)=20, so what would x need to be for f(x) to be 20?  Since f(x) = 2x, we can say 20 = 2x.  Therefore x = 10

f(10) = 20

<u>The rest of (3) are solved in the same fasion.h</u>

<u></u>

<h2><u>For the equation  f(x)= 5x+50</u></h2>

4.a.  f(7) = 5(7)+50

<u>f(7) = 85</u>

4.b. f(-12)

  f(-12) = 5*(-12)+50

<u>f(-12) = -60</u>

<u></u>

Continue in the same fashion for these types of problems.

a ladder leans against the sufe of a house. the angle of elevation of the ladder is 70 degrees when the bottom of the ladder is
nekit [7.7K]

Answer:

≈ 35.1 ft

Step-by-step explanation:

The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°

Using the cosine ratio, with l being the length of the ladder.

cos70° = \frac{adjacent}{hypotenuse} = \frac{12}{l} ( multiply both sides by l )

l × cos70° = 12 ( divide both sides by cos70° )

l = \frac{12}{cos70} ≈ 35.1 ( to the nearest tenth )

The ladder is approx 35.1 ft long
