OverLord2011 [107]

Answer:

David=$8.8

Jo=$13.2

Mary=$22

Step-by-step explanation:

2+3+5=10

44/10=4.4

David=4.4x2=$8.8

Jo=4.4x3=$13.2

Mary=4.4x5=$22

8.8+13.2+22=44

If sin42 degrees = 2/3 then cos48 degrees = what? <br> If tan20.5= 3/8, the tan69.5= what?
Anna11 [10]

Big ifs, question writers. These are of course approximations.

The "co" in cosine comes from complementary angles. It means since

42^\circ + 48 ^\circ = 90^\circ

\sin 42^\circ = \cos 48^\circ

Answer: cos 48° = 2/3

Similarly,

20.5^\circ +69.5^\circ = 90^\circ

\tan 69.5^\circ = \cot 20.5^\circ = \dfrac{1}{\tan 20.5^\circ} = \dfrac 8 3

Answer: tan 69.5° = 8/3

Given that tangent theta = negative 1, what is the value of secant theta, for StartFraction 3 pi Over 2 EndFraction less-than th
vivado [14]

The value of tangent theta is equal to the negative 1.  At this value the value of secant theta is \sqrt{2}.

<h3>What is tangent theta?</h3>

The tangent theta in a triangle is the ratio of sine theta and cos theta. It can be written as,

\rm tan\theta=\dfrac{sin \theta}{cos \theta}

Given information-

The value of tangent theta is equal to the negative 1.

\tan \theta=-1

The tangent theta in a triangle is the ratio of sine theta and cos theta. It can be written as,

\rm tan\theta=\dfrac{sin \theta}{cos \theta}

The value of tangent theta is equal to the negative 1. Thus put the value in above expression as,

\rm -1=\dfrac{sin \theta}{cos \theta}\\

Simplify it further as,

\rm -cos \theta=sin \theta

When the value of cosine and sine theta is equal, then the angle exist in 4th quadrant with the value of \dfrac{7\pi}{4}. Which extent to the \sqrt{2}/2 for the cosine function.

In the trigonometry cosine theta is the reciprocal of the secant theta. Thus,

\rm \dfrac{1}{sec\theta}=\dfrac{\sqrt{2}}{2}\\sec\theta=\sqrt{2}

Thus the value of secant theta is \sqrt{2}

Determine any data values that are missing from the table, assuming that the data represent a linear function.
Varvara68 [4.7K]

Answer:

c. 14

Step-by-step explanation:

Let the missing y value be y2.

If the data represent a linear function, then:

\frac{6 - 2}{2 - 1} = \frac{y_2 - 6}{4 - 2}

\frac{4}{1} = \frac{y_2 - 6}{2}

4 = \frac{y_2 - 6}{2}

Multiply both sides by 2

4 \times 2 = \frac{y_2 - 6}{2} \times 2

8 = y_2 - 6

Add 6 to both sides

8 + 6 = y_2 - 6 + 6

14 = y_2

The missing value is 14
