What conclusion can you draw about angles of elevation for parasailing boats traveling at the same speed?
Answers
Question:
A boat is travelling at 30 mph has a 400 ft. tow line results in the height of the rider in the parasail above the water level of 300 ft.
a) Draw a labelled diagram of the situation
b) Determine the angle of elevation of the parasail rider
c) Parasailing boats traveling at the same speed will have the same angle of elevation
Answer:
a) Please find the attached drawing of the parasail boat created with MS Visio
b) The angle of elevation of the parasail rider from the boat is approximately 48.6°
Step-by-step explanation:
a) Please find the labelled diagram of the parasailing boat created with MS Visio
b) sing trigonometric ratios, we have;
[tex]sin(\theta) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
The opposite leg = The height of the parasail rider above water = 300 ft.
The hypotenuse = the length of the tow line = 400 ft.
θ = The angle of elevation of the parasail rider
[tex]\therefore sin(\theta) = \dfrac{300 \, ft.}{400 \, ft.} = 0.75[/tex]
θ = Arctan(0.75) ≈ 48.6°
The angle of elevation above the horizontal of the parasail rider from the boat, θ ≈ 48.6°
c) From the construction of the drawing and the derivation of the angle of elevation given only the length of the tow line and the height given to the parasail rider by the speed of the both,
Parasailing boats traveling at the same speed, having the same length of tow line, will have the same angle of elevation, provided other factors that have an effect on the angle of elevation are the same

can someone help me find the slope . and tell me how you got the steps and answer. question-What is the slope of the line that passes through the points (-4, -8) and (-10, 8)?
Answers
Answer:
m = -8/3
Step-by-step explanation:
Keep in mind that slope is defined as m = rise / run, or, alternatively,
m = (change in y ) / (change in x).
If we start at (-10, 8) and move to (-4, -8),
the x coordinate is seen to increase by 6 from -10 to -4, and
the y coordinate decrease by 16 from 8 to -8.
Thus, the slope of the line segment connecting these two points is
m = -16 / 6, or m = - 8/3

3x - 5y = 1
3x - y = -7
I currently cannot download any files.
Answers
Answer:
Y=7+3x, x=-3, y=-2
Step-by-step explanation:
3x-5y=1. Equation 1
3x-y=-7. Equation 2
-y=-7-3x isolate for y in equation 2
y=7+3x multiplied by -1 to get positive y
3x-5(7+3x)=1 substitute y value of equation 2 (7+3x) into equation 1
3x-35-15x=1
-12x=36
x=-3
solve for y.
3x-5y=1
3(-3)-5y=1
-9-5y=1

x=7
Step-by-step explanation:
180=25x+5
175=25x
7=x
Answer:
x = 7
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
We know that,
→ Sum of all angles in a line is 180°.
Forming the equation,
→ (13x + 2) + (12x + 3) = 180°
Then the value of x will be,
→ (13x + 2) + (12x + 3) = 180°
→ 13x + 2 + 12x + 3 = 180°
→ (13x + 12x) + (2 + 3) = 180°
→ 25x + 5 = 180°
→ 25x = 180 - 5
→ 25x = 175
→ x = 175/25
→ [ x = 7 ]
Hence, the value of x is 7.

Perimeter is 3 + 3 +3 +4 +5 = 18 feet
Area = 3*3 = 9, 1/2*3*4 = 6, 9 + 6 =15 square feet
perimeter = 2.5 +2.5+ 2.5+2.5+0.5+0.5 = 11 meters
Area = 3*.5 = 1.5, 3*2=6, 6+1.5 = 7.5 square meters
perimeter = 3.14*2*3 = 18.84 +8 = 26.8 inches

Step-by-step explanation:
The perimeter of a shape is just the lengths of its sides added up. Since a square has 4 equal sides, and a side is 26.4, the answer is 26.4 * 4 = 105.6 ft
Add up all of the sides to get the perimeter.
26.4 + 26.4 + 26.4 + 26.4 = 105.6
At a larger pizza party, there are 18 people. Each person wants 3 slices, and each pizza has 8 slices. How many pizzas should they order?

18 people × 3 slices each = 54 slices
54 ÷ 8 = 6.75
7 pizzas
Answer:
They should order 7 pizzas.
Step-by-step explanation:
18 people x 3 slices per person = 54 slices you will need for everyone
54 slices divided by 8 = 6.75 pizzas.
Round 6.75 to 7 pizzas.
They should order 7 pizzas because you cannot ask the pizza place for 6.75 pizzas.
