Answer:

all options are correct.

Step-by-step explanation:

The correct options among all the options are:

  • <em>Ancient mathematicians used trigonometry to find angles of triangles.</em>

        Trigonometry is used to find the size of a missing side or angle in a right-    angled triangle using the sine, cosine or tangent ratios.

  • <em>Ancient mathematicians used trigonometry to track the position of the sun.</em>

It is also used in oceanography in calculating the height of tides in oceans.

  • <em>Tangent was the first trigonometric relationship used by mathematicians.</em>

The three main functions in trigonometry are Sine, Cosine and Tangent.The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions.

  • <em>Cosine was the first trigonometric relationship used by mathematicians. </em>
  • <em>Sine was the first trigonometric relationship used by mathematicians.</em>

A rectangle is 9 ft long and 40 in. wide. What is its area in square feet? (Note: 1 ft = 12 in.)
ivolga24 [154]

Answer: first option

Step-by-step explanation:

Let's make the following conversion:

40 inches to feet (Knowing that 1 feet=12 inches):

(40in)(\frac{1ft}{12in})=3.333ft

The formula for calculate the are of  a rectangle is:

A=l*w

Where l is the lenght and w is the width.

Therefore, when you substitute values, you obtain the following result:

l=9ft\\w=3.33ft\\\\A=(9ft)(3.333ft)\\A=30ft

The cost, c(x), for a taxi ride is given by c(x) = 3x + 2.00, where x is the number of minutes. What does the slope mean for thi
xxTIMURxx [149]
Simple...

you have: C(X)=3x+2.00

x=number of minutes

Pay attention to the y=mx+b form where m=slope-->>

3x is the slope...

so it's 3(times the number of minutes) <<---or (x)

This means that the slope is 3, or the fancy way of saying it-->>"rate of change."

The rate of change of the cost of the taxi ride is $3.00 per minute.

Thus, your answer.
