Answer:

Part A: 1

Part B: -4

Step-by-step explanation:

In a coordinate (x,y), the x-coordinate represents the input of a function and the y-coordinate represents the output.

Part A:

We're looking for the point the line passes through with an x-coordinate (input) of -3. This point is (-3,1) and therefore the output is 1 when the input is -3.

Part B:

We're looking for the point the line passes through with a y-coordinate (output) of 2. This point is (-4,2) and therefore an input of -4 yields an output of 2.

My quadrilateral has no lines of symmetry but it does have rotation symmetry. what is it?”
Elina [12.6K]

We have to identify the quadrilateral with no line of symmetry and have rotational symmetry.

Line of symmetry  is the imaginary line which divide the given quadrilateral in two equal halves.

Rotational symmetry is when an object is rotated around a center point (turned) a number of degrees and the object appear the same.

Parallelogram is a quadrilateral which has no line of symmetry as we can not draw any imaginary line which divides the parallelogram in two equal halves.

But Parallelogram has rotational symmetry as when a parallelogram is rotated around a center point (turned) a number of degrees and parallelogram appear the same.

Hence, Parallelogram is the quadrilateral.

Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters. Write an addition expression in the form Desc
Alex Ar [27]

The sum means that Eric is 3.3 m above sea level.

<h3>What is an addition expression?</h3>

This is a way of taking the sum of two or more expressions.

Given the following parameters

  • The distance while descending = -13.7 meters
  • The distance while ascending = +15.2 meters

An additional expression in the form of Descent + Ascent to represent this situation will be -13.7 + 15+ 2

<u>Calculate the sum:</u>

Sum =  -13.7 + 15+ 2Sum = 3.3 meters

Hence the sum means that Eric is 3.3 m above sea level.

Find the exact values of a) sec of theta b)tan of theta if cos of theta= -4/5 and sin&lt;0
Gre4nikov [31]

Answer:

Using trigonometric ratio:

\sec \theta = \frac{1}{\cos \theta}

\tan \theta = \frac{\sin \theta}{\cos \theta}

From the given statement:

\cos \theta = -\frac{4}{5} and sin < 0

⇒\theta lies in the 3rd quadrant.

then;

\sec \theta = \frac{1}{-\frac{4}{5}} = -\frac{5}{4}

Using trigonometry identities:

\sin \theta = \pm \sqrt{1-\cos^2 \theta}

Substitute the given values we have;

\sin \theta = \pm\sqrt{1-(\frac{-4}{5})^2 } =\pm\sqrt{1-\frac{16}{25}} =\pm\sqrt{\frac{25-16}{25}} =\pm \sqrt{\frac{9}{25} } = \pm\frac{3}{5}

Since, sin < 0

⇒\sin \theta = -\frac{3}{5}

now, find \tan \theta:

\tan \theta = \frac{\sin \theta}{\cos \theta}

Substitute the given values we have;

\tan \theta = \frac{-\frac{3}{5} }{-\frac{4}{5} } = \frac{3}{5}\times \frac{5}{4} = \frac{3}{4}

Therefore, the exact value of:

(a)

\sec \theta =-\frac{5}{4}

(b)

\tan \theta= \frac{3}{4}
