Given the point:
(x, y) ==. (9, 6)
Let's write the equation of the horizontal line that goes through the given point.
On a horizonal line, every point on the line has the same value of y.
The slope of a horizontal line is 0.
Since every point on a horizontal line has the same value of y, to find the equation of a horizontal line, we are to use the y-coordinate of the point to find the equation of the horizontal line.
We have:
y-coordinate of the point = 6
Hence, the equation of the horizontal line that goes through the point is:
y = 6
ANSWER:
y = 6

Two birds spot a cat trying to jump up to their cage Find the angle of depression of the cat.
Step 1
Draw the triangle for clarity
From the diagram above it is clear, the angle of depression is equal to the angle of elevation since both angles are alternate interior angles. Therefore, we can go ahead to find the angle of elevation which is equal to the angle of depression.
Step 2
Find the angle of depression using SohCahToa
To find this angle we will use the ratio Cah written as
[tex]\begin{gathered} \cos x=\frac{adjacent}{\text{hypotenuse}} \\ \text{adjacent}=4ft \\ \text{hypotenuse}=5ft \end{gathered}[/tex][tex]\begin{gathered} \cos x=\frac{4}{5} \\ x=\cos ^{-1}(\frac{4}{5}) \\ x=36.86989765^{\circ}_{} \\ x\approx36.9^{\circ}\text{ to 1 decimal places} \end{gathered}[/tex]Hence the angle of depression of the cat, x to 1 decimal place = 36.9°

Let us find out if the given two triangles ABC and DEF are similar triangles or not.
Triangle ABC is a right-angled triangle so we can apply the Pythagorean theorem to find the missing side.
[tex]a^2+b^2=c^2[/tex]Where a and b are the shorter sides and c is the longest side (hypotenuse)
[tex]\begin{gathered} 20^2+21^2=c^2 \\ 400+441=c^2 \\ 841=c^2 \\ \sqrt[]{841}=c \\ 29=c \\ c=29 \end{gathered}[/tex]Similarly, we can apply the Pythagorean theorem to triangle DEF to find the missing side.
[tex]\begin{gathered} d^2+e^2=f^2 \\ 40^2+e^2=58^2 \\ e^2=58^2-40^2 \\ e^2=3364-1600 \\ e^2=1764 \\ e=\sqrt[]{1764} \\ e=42 \end{gathered}[/tex]Now, recall that two triangles are similar if the ratio of the corresponding sides is equal.
The corresponding sides are
AB = DE
BC = EF
AC = DF
[tex]\begin{gathered} \frac{DE}{AB}=\frac{EF}{BC}=\frac{DF}{AC} \\ \frac{40}{20}=\frac{42}{21}=\frac{58}{29} \\ \frac{2}{1}=\frac{2}{1}=\frac{2}{1} \end{gathered}[/tex]As you can see, the ratio of the corresponding sides of the two triangles is equal.
Hence, the triangles ABC and DEF are similar.

The length of a rectangle is given by the function l(x)=12x2+2x+4. The width of the rectangle is given by the function w(x)=3x−1.Which function represents the area of the rectangle?
The area of a rectangle is given by the next equation:
Area = Length * Width
Where
Length =1/2x²+2x+4.
and
Width = 3x−1
Replacing:
Area = (1/2x²+2x+4)* (3x-1)
Solve the operation:
(1/2x²* 3x) + (1/2x²*-1)+(2x*3x)+(2x*-1)+(4*3x)+(4*-1)
Simplify:
3/2x³-1/2x²+6x²-2x+12x-4
= 3/2x³+11/2x²+10x-4
Hence, the correct answer is a(x)=3/2x³+11/2x²+10x-4
Answer:a(x)=3/2x³+11/2x²+10x-4

Jimmy's school is selling tickets to a play. On the first day of ticket sales the school sold 12 senior citizentickets and 5 child tickets for a total of $173. The school took in $74 on the second day by selling 1 seniorcitizen ticket and 5 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.
SOLUTION
Let s represent senior citizen tickets
and let c represent child ticket
On the first day the school sold 12 senior tickets and 5 child's tickets for $173.
This will be represented algebraically by 12s + 5c = 173 ..... equation 1
The following day they sold 1 senior ticket and 5 child's tickets for $74.
This will be represented by s + 5c = 74 ....... equation 2
Now we will solve equations 1 and 2 simultaneously we have

Trigonometric Equations
Solve for x in R:
[tex]sin\text{ }\frac{x}{4}=\frac{\sqrt{2}}{2}[/tex]There are two angles whose sine is the given value: 45° and 135°. We need to express them in radians:
[tex]45^o=45\text{ }\frac{\pi}{180}=\frac{\pi}{4}[/tex][tex]135^o=135\frac{\pi}{180}=\frac{3\pi}{4}[/tex]Thus, we have two solutions:
[tex]\begin{gathered} \frac{x}{4}=\frac{\pi}{4} \\ x=\pi \\ And: \\ \frac{x}{4}=\frac{3\pi}{4} \\ x=3\pi \end{gathered}[/tex]Both solutions point to the same terminal angle, so we only have one solution in the first rotation of the angle:
x = π
Since it's required to find the solution for all the real numbers, we must account for all the possible angles in any number of rotations clockwise or counterclockwise as follows:
x = π + 2kπ
Where k is an integer number. For example, for k = 1, we have the already-found solution above x = 3π
the volume of a recrangular prism is 72 centimeters.the prism is 2 centimeters wide and 4 centimeters high. what is the length of the prism
The volume of a rectangular prism is given by:
[tex]V=w\cdot l\cdot h[/tex]We know that the volume is 72 cub cm, the width is 2 cm and the height is 4 cm. Plugging this value in the equation we have:
[tex]72=2\cdot l\cdot4[/tex]Solving the equation for l we have:
[tex]\begin{gathered} 72=2\cdot l\cdot4 \\ 72=8l \\ l=\frac{72}{8} \\ l=9 \end{gathered}[/tex]Therefore the lenght of the prism is 9 cm.
The missing side length in the right triangle is __ cm.
364
1) Assuming this is a right triangle, the side whose length is 365 is the hypotenuse, so we can write out the Pythagorean Theorem:
365² = 27² +c²
133225 =729+ c²
133225 -729 = c²
132496= c² Take the square root on both sides
√132496 = √c²
c = 364
2) Hence, the missing leg is 364 cm

(b)Dan leaves his house on his bike. He rides at a constant speed until he reaches a lemonade stand, where he parks his bike and takes a rest. Then he turns around and bikes home as fast as he can.
Answer:
The correct answer is the second graph.
Explanation:
Dan leaves his house at a constant speed. Then, the time starts counting, and his graph is a line that starts in (0, 0)
Then, he stops, we can see this part in the graph constant. Because he is not moving, the distance from his house remains the same.
Finally, goes back and we can this as a line. Since he is going at a faster speed, the line is more steep.
This is what we can see in the second graph

A triangle with side lengths 8, 15, and 17 is a right triangle by theconverse of thePythagorean Theorem. What are the measures of the other 2 angles?Round your answers to the nearest whole number.HINT: Draw a diagram of this problem and label your triangle.The méasure of the smaller acute angle is ____degreesand the larger acute angle measures_______degrees.
We are given a right-angle triangle with side lengths 8, 15, and 17.
Since it is a right triangle, one angle must be 90°
Let us find the other two angles of this right triangle.
With respect to angle x, the opposite side is 15 and the hypotenuse side is 17.
Recall from the trigonometric ratios,
[tex]\begin{gathered} \sin (x)=\frac{\text{opposite}}{\text{hypotenuse}} \\ \sin (x)=\frac{15}{17} \\ x=\sin ^{-1}(\frac{15}{17}) \\ x=61.9\degree \end{gathered}[/tex]So, the second angle is 61.9°
Recall that the sum of angles inside a triangle must be equal to 180°
So, the third angle can be found as
[tex]\begin{gathered} y+61.9\degree+90\degree=180\degree \\ y=180\degree-90\degree-61.9\degree \\ y=28.1\degree \end{gathered}[/tex]So, the third angle is 28.1°
The measure of the smaller acute angle is 28.1 degrees and the larger acute angle measures 61.9 degrees.
