Answer:

2cm = 15 mi

you have to figure out how far 7cm equals, so you would have:

6cm = 45 mi

that leaves 1 cm left, so if 2cm = 15 mi then 1 cm would equal 7.5 mi.

so your distance would be 45 mi + 7.5 mi = 52.5 mi to the next town.

The point (-3/5,y)in the third quadrant corresponds to angle θ on the unit circle.
anastassius [24]
The given point (-3/5 , y) lies in the third quadrant.
It is also given that the point lies on a unit circle.

For a point (x,y) lying on a unit circle a and y are defined as:

x = cos θ
y = sin θ

So, we can say for the point (-3/5 , y) the value -3/5 is equal to cos θ

sec θ is the reciprocal of cos θ.

So, sec θ = -5/3

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

Using Pythagorean identity we can first find sin θ.

sin \theta = - \sqrt{1- cos^{2}\theta }  \\  \\ 
sin\theta= \sqrt{1-( -\frac{3}{5})^{2} }=-  \frac{4}{5}

Since the point lies in 3rd quadrant, both sin and cos will be negative.

So, now we can write:

cot\theta= \frac{ \frac{-3}{5} }{ \frac{-4}{5} } \\  \\ 
cot\theta= \frac{3}{4}

Answers:
sec θ = -5/3
cot θ = 3/4

The graph of f(x) = StartRoot x EndRoot is reflected across the x-axis and then across the y-axis to create the graph of functio
allsm [11]

Answer:

The true statements:

The only value that is in the domains of both functions is 0.

The range of g(x) is all values less than or equal to 0.

==================================

Step-by-step explanation:

See the attached figure:

As shown: f(x) = √x with blue color

When f(x) is reflected across the x-axis the result will be (-√x) with red color.

Then the is reflected result across the y-axis to create the graph of function g(x) = -√(-x) with green color.

<u>Domain </u>of f(x) = [0,∞) & <u>Range</u> of f(x) = [0,∞)

<u>Domain </u>of g(x) = (-∞,0] & <u>Range </u>of g(x) = (-∞,0]

So, according to previous, we will check the statements:

1) The functions have the same range. <u>(Wrong)</u>

2) The functions have the same domains. <u>(Wrong)</u>

3) The only value that is in the domains of both functions is 0. <u>(True)</u>

4) There are no values that are in the ranges of both functions. <u>(Wrong)</u>

5) The domain of g(x) is all values greater than or equal to 0. <u>(Wrong)</u>

6) The range of g(x) is all values less than or equal to 0. <u>(True)</u>
