1.In a right triangle, &lt;A and &lt;B are acute. Find the value of csc A, when tan A = 8/15.
bekas [8.4K]

Answer:

(1)csc A=\dfrac{17}{8}

(2)sec A=\dfrac{17}{15}

Step-by-step explanation:

<u />Tan A=\dfrac{8}{15}\\$In Trigonometry, $Tan A=\dfrac{Opposite}{Adjacent}\\$Therefore:\\Opposite=8, Adjacent=15<u />

Using Pythagoras theorem

Hypotenuse^2=Opposite^2+Adjacent^2\\Hypotenuse^2=8^2+15^2\\Hypotenuse^2=289\\Hypotenuse^2=17^2\\Hypotenuse=17

<u>Question 1</u>

Now, cosecant = 1/sin

Therefore:

csc A=\dfrac{Hypotenuse}{Opposite}\\csc A=\dfrac{17}{8}

<u>Question 2</u>

Now, secant = 1/cos

Therefore:

sec A=\dfrac{Hypotenuse}{Adjacent}\\sec A=\dfrac{17}{15}

Again, look for repeated entries in the domain.  If present, the relation cannot be a function.  1 maps 6 to 1, 2, and 3; 2 maps 5 to -1 and 9; 3 maps 1 to -6 and 0; and only 4 has no double mapping.  Therefore 4 is a function and the answer.

Explain how you can write an equation for a line with slope 1/2 that crosses the y-axis at the point (0,-1).
andre [41]

Answer:

y= 1/2x-1

Step-by-step explanation:

The equation of a line is y= mx+c

m represents the slope of the line

c represents the y-intercept

So we plug in our information into the equation.

The slope is 1/2 so y= 1/2x + c

The line crosses at (0,-1) which makes -1 the y-intercept as the line crosses at this point on the y-axis.

Therefore, y= 1/2x-1
