A boat sails directly away from a skyscraper located on the edge of a large lake. The skyscraper is 120 meters tall. A photographer on the boat is taking pictures of the skyscraper with a camera that has a 28° viewing lens.
Let's begin by identifying key information given to us:
[tex]\begin{gathered} Height(h)=120m \\ \theta=28^{\circ} \\ d=\text{?} \end{gathered}[/tex]We will use the Trigonometric ratio (SOHCAHTOA) to solve for d. In this case, we will use ''TOA''
[tex]\begin{gathered} TOA\Rightarrow tan\theta=\frac{opposite}{adjacent} \\ tan\theta=\frac{opposite}{adjacent} \\ opposite\Rightarrow height=120m \\ adjacent\Rightarrow d \\ \theta=28^{\circ} \\ tan28^{\circ}=\frac{120}{d} \\ d\cdot tan28^{\circ}=120 \\ d=\frac{120}{tan28^{\circ}}=225.687\approx226 \\ d=226m \end{gathered}[/tex]Find the absolute change and the relative change in the following cases.The number of refugees in the world increased from 8.7 million in 2005 to 16.1 million in 2015.
absolute change is determined by the absolute value of the subtraction of the number of refugees in both years:
absolute change = | 16.1 million - 8.7 million | = 7.4 million
Relative change is given by the quotient between final value and initial value, just as follow:
relative change = final value / initial value
= 16.1 million / 8.7 million
= 1.85
Hence, the absolute change is 7.4 million and relative change is of 1.85

Gordon works for a graphic design firm and is creating a label for a food truck vendor. The vendor specializes in finger food and wants to sell food in right conical containers so that they are easy for people to hold. To complete his label, Gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. Gordon has been told that the containers have a diameter of 4 inches and a height of 6 inches.
Part A
Find out the slant height of the cone
Applying the Pythagorean Theorem
AC^2=AB^2+BC^2
we have
AC ----> slant height
AB=4/2=2 in
BC=6 in

What is the arc length of each sector between any two cars? (4 points)c.) What is the area of each sector between any two cars?
The carnival ride is in shape of wheel with 25ft radius.
The wheel has 20 cars attached to the center of the wheel. Since the cars are evenly distributed, we can thus find the
the measure of the angle between each car by dividing 360 degrees by 20.
#A:
The measure of each central angle between any two cars is:
[tex]\frac{360}{20}=18^0[/tex]#B:
Hence, we can find the length of the arch between any two cars is given by the length of arc formula given below:
[tex]\begin{gathered} \frac{\theta}{360}\times2\pi r \\ \text{where,} \\ r=\text{radius} \\ \theta=\text{measure of each central angle betw}een\text{ two cars} \end{gathered}[/tex]Let us calculate this length below:
[tex]\begin{gathered} \theta=18^0 \\ \frac{18}{360}\times2\pi\times25 \\ =2.5\pi=7.85\text{ (to the nearest hundredth)} \end{gathered}[/tex]#C:
We are asked to find the area of each sector between two cars.
The area of a sector of a circle is:
[tex]\frac{\theta}{360}\times\pi\times r^2[/tex]Since we have all the parameters, let us calculate this area:
[tex]\begin{gathered} Area=\frac{18}{360}\times\pi\times25^2 \\ \\ Area=98.13\text{ (to nearest hundredth)} \end{gathered}[/tex]Therefore, the final answers are:
#A: angle = 18 degrees
#B length = 7.85 feet
#C Area = 98.13 squared feet
What is the solution to -4y=28 please explain
You have the equation -4y=28
To solve this equation you need to clear the value of the unknown variable y, meaning, you have to simplfy the equation until you reach y=
For this, since y is multiplied by -4 you have to divide it by -4 to leave y alone, and what you do in one side of the equation must be done to the other side to keep the equality:
[tex]\begin{gathered} -4y=28 \\ \frac{-4y}{-4}=\frac{28}{-4} \\ y=-7 \end{gathered}[/tex]The value of y=-7
Find the area of the sector of a circle with diameter 30 feet and an angle of 3Pi/5 radians. Round your answer to four decimal places.
half the diameter is the radius, so
[tex]r=15[/tex]now we can calculate the total area of the circle , and then will calculate the area for the angle
[tex]\begin{gathered} A=\pi\times r^2 \\ A=\pi\times15^2 \\ A=225\pi \end{gathered}[/tex]the area of the circle is 225pi, this is the corresponding area for the complete angle of the circle, therefore it is equivalent to 2pi
now we create a relation to find the area corresponding to the indicated angle

[tex]\begin{gathered} 225\pi\longrightarrow2\pi \\ x\longrightarrow\frac{3}{5}\pi \end{gathered}[/tex]where x is the area covered by the angle
we solve ussing cross multiplication, x is equal to: multiply the values that are found diagonally and make them equal
[tex]\begin{gathered} x\times2\pi=\frac{3}{5}\pi\times225\pi \\ \end{gathered}[/tex]and solve for x
[tex]\begin{gathered} x=\frac{\frac{3}{5}\pi\times225\pi}{2\pi} \\ \\ x=\frac{135\pi^2}{2\pi} \\ \\ x=67.5\pi\approx212.0575 \end{gathered}[/tex]The rounded area is 212.0575 square feet
Given ST is tangent to circle Q, find the value of r
Given the figure of the circle Q
As shown, ST is tangent to circle Q
So, ST is perpendicular to the radius QS
So, the triangle QST is a right-angle triangle
We can apply the Pythagorean theorem where the legs are QS and ST
And the hypotenuse is QT
The side lengths of the triangle are as follows:
QS = r
ST = 48
QT = r + 36
So, we can write the following equation:
[tex]\begin{gathered} QT^2=QS^2+ST^2 \\ (r+36)^2=r^2+48^2 \end{gathered}[/tex]Expand then simplify the last expression:
[tex]\begin{gathered} r^2+2*36r+36^2=r^2+48^2 \\ r^2+72r+1296=r^2+2304 \end{gathered}[/tex]Combine the like terms then solve for (r):
[tex]\begin{gathered} r^2+72r-r^2=2304-1296 \\ 72r=1008 \\ \\ r=\frac{1008}{72}=14 \end{gathered}[/tex]So, the answer will be r = 14

time=0
replace
[tex]\begin{gathered} y=a(b)^x \\ 2363=a(b^0) \\ 2363=a\cdot1 \\ 2363=a \end{gathered}[/tex]b) If the number of bacteria doubles every 157 minutes
[tex]\begin{gathered} (2363\cdot2)=2363(b^{157}) \\ (2363\cdot2)=2363(b^{157}) \\ 4726=2363b^{157} \\ \text{divide both sides by }2363 \\ \frac{4726}{2363}=\frac{2363b^{157}}{2363} \\ 2=b^{157} \\ 2^{(\frac{1}{157})}=(b^{157})^{\frac{1}{157}} \\ 1.00442471045\text{ =b} \end{gathered}[/tex]so, the function is
[tex]y=2363(1.00442471045)^x[/tex]Step 2
