Answer:
h ≈ 235
Step-by-step explanation:
We know there is a tower with h height. There is also a wire (that's diagonal) travelling to the ground. It touches the ground. The angle it makes with the ground is 57°.
Refer to the image below of what the problem should look like.
Refer to the trigonometric ratios:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
We can use sine because we are looking for the opposite side (to the angle) and we have the hypotenuse. So:
sine = opposite side/hypotenuse
sin(57) = h/280
sin(57) / 1 = h / 280
Cross multiply:
sin(57) (280) = 1 (h)
Input to calculator:
h = 234.827759...
h ≈ 235

Answer:
y=-2x+1
Step-by-step explanation:
First, you calculate the slope, which is rise over run: -9+5 / 5-3 = -2. Then, find b by substituting the coordinates (of either one point) into the slope-intercept formula, y = mx + b.
Answer:
Step-by-step explanation:
The slope intercept form of a line is
y=mx+b, where m=slope and b= y intercept
The slope of a line is defined as
m=(y2-y1)/(x2-x1), in this case we have points (3,-5) and (5,-9)
m=(-9-(-5))/(5-3)
m=-4/2
m=-2, so our line is now
y=-2x+b, using point (3,-5) we can now solve for b
-5=-2(3)+b
-5=-6+b
1=b so the completed line is
y=-2x+1

A deep sea diver started at sea level (0 feet) and dove at a rate of 5.6 feet per minute. If the diver dove for ½ hour, what rational number represents his position relative to sea level? Show your work. A. 168 feet B. 2.8 feet C. -2.8 feet D. -168 feet
Answers
Given:
A deep sea diver started at sea level (0 feet).
Rate of diving = 5.6 feet per minute.
Time = [tex]\dfrac{1}{2}[/tex] hour
To find:
The rational number that represents his position relative to sea level.
Solution:
We know that,
1 hour = 60 minutes
[tex]\dfrac{1}{2}[/tex] hour = 30 minutes
A deep sea diver, dove at a rate of 5.6 feet per minute.
Distance covered in 1 minute = 5.6 feet
Distance covered in 30 minute = 30 × 5.6 feet
= 168 feet
The diver dove 168 feet in [tex]\dfrac{1}{2}[/tex] hour. Since it is below the sea level, therefore it should be negative.
So, the rational number that represents his position relative to sea level is [tex]-168[/tex] feet.
Therefore, the correct option is D.

Hello There!
The shown figure is a trapezoid
The formula for area of a trapezoid is
[tex]A=\frac{a+b}{2} h[/tex]
where a = base 1
b = base 2
h = height
the dimensions given are
13 & 7 - bases
5 - height
so all we have to do is plug in the values into the formula
[tex]A=\frac{7+13}{2} 5\\7+13=20\\\frac{20}{2} = 10\\10*5=50\\A=50[/tex]
So we can conclude that the area of the trapezoid is 50 cm²

Which shape shows the cross-section of the square pyramid when it is cut by a plane parallel to the base?
Answers
Answer:
Triangle
Step-by-step explanation:
A pyramid is a strong-solid shape that is comprised of triangles, square shapes, squares, and different polygons. Pyramids are arranged depending on the state of their base. For instance, the outline given is a square-based pyramid in light of the state of its base(which is a square). Different sorts incorporate the three-sided based pyramid, three-sided based pyramid, and other polygon-based pyramids.
In the event that this square pyramid is cut with a plane that is corresponding to the base of the pyramid, the state of its cross-area will be a triangle since the shapes that are corresponding to the base are altogether triangles. So slicing the plane corresponding to the base is like removing one side of the triangle making up the pyramid.

Answer:
C = 150.72 cm
A = 1808.64 [tex]cm^{2}[/tex]
Step-by-step explanation:
circumference = 2π[tex]r[/tex]
r = 24 (48 ÷ 2)
substitute 24 for r
C = 2 × 3.14 × 24
C = 150.72
Area = π[tex]r^{2}[/tex]
r = 24
substitute 24 for r
A = 3.14 × [tex]24^{2}[/tex]
A = 3.14 × 576
A = 1808.64
= 3.14 x 48
= 150.72 cm
radius =48 divide by 2
= 24
area = π x r x r
= 3.14 x 24 x 24
= 1808.64 cm2
