Step-by-step explanation:
The organizers want the zip line to have two platforms (towers / anchors). The first platform (on the higher ground) should be about 50 m away from the second platform. The slope length from the top of platform one to the top of platform two should be about 70 m. What would be the angle of depression from platform one to two to the nearest degree?
Answer:
The angle if depression is 44.4 degree.
Step-by-step explanation:
horizontal distance, d = 50 m
slope length, L = 70 m
The angle of depression is given by
[tex]cos\theta=\frac{d}{L}\\\\cos \theta = \frac{50}{70}\\\\cos \theta = 0.714\\\\\theta = 44.4^o[/tex]

What is the area of the polygon given below?
Answer:
C, which is 340!
Step-by-step explanation:
Split the polygon into two rectangles to make it easier (see the attachment below), and calculate the areas of both rectangles. Then add the areas of the two rectangles, 264+76=340. So the answer is 340 square units, or C. Hope this helped!! :)
The area of polygon = 340 square units.
How to estimate the area of the polygon?Area of rectangle = Length [tex]\times[/tex] [tex]\tmes[/tex]breadth
Area of rectangle (side A) = 19 [tex]\times[/tex] 4 = 76
Area of rectangle (Side B) = 24 [tex]\times[/tex] 14 = 264
To estimate the area of the polygon, add both of the equations then we get
Area of the polygon
= Area of a rectangle (side A) + Area of a rectangle (Side B)
= 76 + 264
Area of the polygon = 340 square units.
Therefore, the correct answer is option C. 340 square units.

Y=
Answer:
y=2
Step-by-step explanation:
3 = (y+7)/3
Multiply each side by 3
3*3 = (y+7)/3 *3
3*3 = y+7
9 = y+7
Subtract 7 from each side
9-7 = y+7-7
2 =y
Answer:
2 = y
Step-by-step explanation:
3 = y + 7 ÷ 3
multiply both side of equation by 3
3 × 3 = y + 7 ÷ 3 / 3
9 = y + 7
subtract 7 from both side
9 - 7 = y + 7 - 7

Step-by-step explanation:
using pythagoras theorem
a^2 + b^2 = c^2
4^2 + y^2 = 21^2
16 + y^2 = 441
y^2 = 441 - 16
y^2 = 425
[tex]y = \sqrt{425}[/tex]
[tex]y = 5\sqrt{17}[/tex]
y = 13.2
a^2 + b^2 = c^2
4^2 + x^2 = 7^2
16 + x^2 = 49
x^2 = 40 - 16
x^2 = 33
x = [tex]\sqrt{33}[/tex]

What is the simplest radical form of the expression? (8x5y3)23
This may be incorrect, so sorry if it is! The answer I got is 2760y.
somebody help me out !
Answer:
224
Step-by-step explanation:
Hello!
To find f(-7) you simply plug the value, -7, into the function.
This will get you:
f(-7) = 4(-7)^2 - 4(-7)
Remember that the square of a negative number is a positive! Also, remember to use the order of operations (PEMDAS)!
This will get you:
f(-7) = 4(49) - 4(-7)
f(-7) = 196 - (-28)
f(-7) = 224

How do you ratify the denominator for 2/ 2(sqrt2)? When I multiply by sqrt2/sqrt 2 I'm still left with a radical in the denominator.
Answer: [tex]\dfrac{\sqrt{2}}{2}[/tex]
Step-by-step explanation:
Given
The fraction is [tex]\dfrac{2}{2\sqrt{2}}[/tex]
Making denominator a number, multiply and divide by [tex]\sqrt{2}[/tex]
[tex]\Rightarrow \dfrac{2}{2\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}\\\\\Rightarrow \dfrac{2\sqrt{2}}{2\sqrt{2}\times \sqrt{2}}=\dfrac{2\sqrt{2}}{2\sqrt{2\times 2}}\\\\\text{cancel out the common term 2}\\\\\Rightarrow \dfrac{\sqrt{2}}{2}[/tex]
how much work is done when you lift an object that weighs 150 N to a height of 5 meters
Answer:
Work done = 150 x 5 = 750 J
Step-by-step explanation:
Work done is the measure of energy transferred to an object when a force is added causing the object to move a distance in the direction of the force.
The equation for work done is force time the distance and is measured in Joules. Therefore the formula is W = F x D
work done (W) is measured in joules (J)
force (F) is measured in newtons (N)
distance (d) is in the same direction as the force and is measured in
metres (m)
W = F x D
w = 150 x 5
W = 750 J
