At what value of w does the graph have a vertical asymptote? Explain how you know and what this asymptote means in the situation.
Answers
Vertical asymptote are vertical lines which corresponds to the zeros of the denominator of our rational function. Then, the zeros of T(w) ocurr when
[tex]530-w=0[/tex]which gives
[tex]w=530[/tex]Therefore, the vertical asymptote is w = 530.
The asymptote is a line that the graph function approaches but never touches. In our case, this means that the speed of the wind is very close to 530 mph but never touches this value.

x+y=3
y=2x-3
Answers
Answer:
The answer would be y=3, and there is only one solution.
Step-by-step explanation:
In the first expression, x+y=3, we can rearrange it to get it in terms of x so we can substitute it for x in the second expression.
x+y=3
Subtract y from both sides: x=-y+3
Substitute x=-y+3 into the second expression: y=2(-y+3)+3
Distribute the 2: y=-2y+6+3
Simplify the right side: y=-2y+9
Add 2y to both sides: 3y=9
Divide by 3: y=3
Since there is a single y coordinate, that means that there is only one solution.

5 2/5 × 0.8A. 4.32B. 5.76C.7.80D.2.75
Answers
Answer:
A. 4.32
Explanation:
First, we need to transform the mixed number 5 2/5 into a decimal number as:
[tex]5\frac{2}{5}=5+\frac{2}{5}=5+0.4=5.4[/tex]Then, we can multiply 5.4 by 0.8, so:
[tex]5\frac{2}{5}\times0.8=5.4\times0.8=4.32[/tex]To multiply 5.4 by 0.8, we can multiply the numbers normally without taking into account the decimal points. So 54 times 08 is equal to:
Then, 5.4 has one digit after the decimal point and 0.8 has one digit after the decimal point. So, in total, we have two digits after the decimal point. It means that the result is equal to 4.32 because we need two digits after the decimal point.
Therefore, the answer is 4.32

(a) Find an angle between 0 and 2π that is coterminal with -13π/12.
To get coterminal angles, we simply have to add or subtract 2π. In this problem, we are looking for a coterminal angle that is between 0 and 2π, so we will add 2π to -13π/12:

Answers
The given function is
[tex]w(x)=70x[/tex]Where x is minutes.
(a) To find the number of words typed in 5 minutes, we just need to replace the variable for 5 and solve
[tex]w(5)=70(5)=350[/tex]Therefore, there are typed 350 words in 5 minutes.
(b) We do the same process for 8 minutes.
[tex]w(8)=70(8)=560[/tex]Therefore, there are typed 560 words in 8 minutes.
(c) To find the type for 280 words, now we replace the other variable w(x), and solve for x
[tex]280=70x[/tex]We divide the equation by 70
[tex]\frac{280}{70}=\frac{70x}{70}\rightarrow x=4[/tex]Therefore, 280 words take 4 minutes.

[tex]\begin{gathered} slope=1.82 \\ where \\ slope=\frac{increase\text{ in amout of money spent}}{increase\text{ in the number of hours worked}} \end{gathered}[/tex]Thus, we have
[tex]\begin{gathered} 1.82=\frac{increase\text{ in amount of money spent}}{1} \\ \Rightarrow predicted\text{ increase in amount of money spent on entertainment = \$1.82} \end{gathered}[/tex]B) Predicted amount of money spent on entertainment for a student with no number of hours worked
This implies that from the equation of the line of best fit, the value of x is zero.

We have start with circle B, which is a circle with radius equals to 3 and centered at (4, 4).
The circle A has a radius equals to 4. If we dilate the image of the circle B around the center of circle A by the ratio between the radius, we're going to have circle A.
Translation means the displacement of a figure or a shape from one place to another. If we translate the circle B 8 units to the left, The image is going to have the same center as circle A.
The transformations that takes circle B to circle A are a dilation around (4, 4) by a factor of 4/3, and then a horizontal translation of 8 units to the left.

It is given to us that -
∠5 = 130
and, ∠3 = 13x
We have to find out the value of x.
Here, we have two parallel lines. Parallel lines are the lines that do not intersect at any points.
There is also a transversal that passes through the two parallel lines in the same plane intersecting the parallel lines at two separate points.
When a transversal cuts two parallel lines, there are different angles formed as shown in the figure.
∠3 and ∠5 are co-interior angles that lie on the same side of the transversal.
So, ∠3 + ∠5 = 180
=> 13x + 130 = 180
=> 13x = 50
=> x = 3.84
Thus, from the value of the sum of co-interior angles, we find that the value of x is 3.84.
