You are looking at the New York ball drop on New Year’s Eve at a distance of 100 m away from the base of the structure. If the ball drops at a constant rate of 2 m/s, what is the rate of change of the
angel between you and the ball when the angle is ( ?
The question is an illustration of related rates.
The rate of change between you and the ball is 0.01 rad per second
I added an attachment to illustrate the given parameters.
The representations on the attachment are:
[tex]\mathbf{x = 100\ m}[/tex]
[tex]\mathbf{\frac{dy}{dt} = 2\ ms^{-1}}[/tex] ---- the rate
[tex]\mathbf{\theta = \frac{\pi}{4}}[/tex]
First, we calculate the vertical distance (y) using tangent ratio
[tex]\mathbf{\tan(\theta) = \frac{y}{x}}[/tex]
Substitute 100 for x
[tex]\mathbf{y = 100\tan(\theta) }[/tex]
[tex]\mathbf{\tan(\theta) = \frac{y}{100}}[/tex]
Differentiate both sides with respect to time (t)
[tex]\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}[/tex]
Substitute values for the rates and [tex]\mathbf{\theta }[/tex]
[tex]\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
This gives
[tex]\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
[tex]\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
Divide both sides by 2
[tex]\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }[/tex]
[tex]\mathbf{ \frac{d\theta}{dt} = 0.01 }[/tex]
Hence, the rate of change between you and the ball is 0.01 rad per second

Given the endpoints D(-2, 3) and L(4,1)
Find the midpoint of DL.
Answer:
Midpoint = (1,2)
Step-by-step explanation:
Using coordinates: D(-2,3) and L(4,1)
Using the midpoint formula:
Midpoint of DL = (D1 + L1) / 2, (D2 + L2) / 2
Midpoint of DL = (-2 + 4) / 2, (3 + 1) / 2
Midpoint of DL = (2) / 2, (4) / 2
Therefore the midpoint of DL is (1,2)

3b- 4/2 = c , for b
please explain the steps
Answer:
b = c/3 + 2/3
Step-by-step explanation:
3b - 4/2 = c
the goal is to have b all by itself on one side of the equals sign.
start by moving the fraction over to where c is by adding.
3b = c + 4/2
adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.
Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)
b = c/3 + 2/3
notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3

Write 16 as a percentage of 54, give your answer correct to the nearest whole number.
Answer:
30
Step-by-step explanation:
16/54 as a percentage is 29.6296%. round up to get the nearest whole number.
29.6296 rounded up is 30
Answer:
16 = 30% of 54

A bird weighs 10 N and is standing 3 m up whats its GPE
Answer:
30 J
Step-by-step explanation:
Given : -
Height ( h ) = 3m
Weight ( W ) = 10 N
To find : GPE = ?
Note : -
GPE is Gravitational Potential Energy.
It is expressed in Joules ( J ).
Formula : -
W = mg
mg = 10 N
Formula : -
GPE = mgh
GPE = 10 x 3
GPE = 30 J
Therefore,
A bird weighs 10 N and is standing 3 m, it's
GPE is 30 J.
Answer:
The answer is GPE = 300 Nm (Newton meters)
Step-by-step explanation:
The bird's mass weighs to 10 Newtons.
Presuming this took place on Earth, the gravitational force is 10 Newtons.
The bird is standing 3 meters above the ground.
Using the GPE formula (GPE = mgw,) the answer should be 300 Newton metres.

write the log equation as an exponential equation. you do not need to solve for x.
Answer:
[tex]5^{1/6} =2x[/tex]
Step-by-step explanation:
Log and exponential forms are inverses. Additionally, the information from one can be used to write in it another form. In a log equation, there are three parts. The formula is [tex]log_{b}(x)=y[/tex]. The formula for exponential equations is [tex]b^y=x[/tex]. This means to find this equation in exponential form write 5 as the base, 1/6 as the power, and 2x as the other side of the equation. This looks like, [tex]5^{1/6} =2x[/tex].

Answer:
ΔAOK ≅ ΔBOL by SAS
Step-by-step explanation:
Hello there!
We are given:
Line segment AB intersects line segment KL at point O
O is the midpoint of AB
O is the midpoint of L
We want to prove that ΔAOK is congruent to ΔBOL
From the given picture, line segments AK and LB don't exist, but we can draw them in
Once we've drawn them in, we can use the given information to help us
Since O is the midpoint of AB, AO = OB by the definition of a midpoint
O is also the midpoint of LK, and because of that, LO=OK, also because of the definition of a midpoint
Since O is the intersection of AB and KL, that means that O would help form the vertical angles <LOB and <KOA (which are congruent because of vertical angles theorem)
Now, we have 2 sides and an angle which are congruent.
In the answer, we already have ΔAOK filled in
Remember that when naming congruent triangles, the congruent pieces need to match
A corresponds with B
O corresponds with O
K corresponds with L
So, that means ΔAOK ≅ ΔBOL
The reason is because of SAS (side-angle-side). The reason why it's SAS is because we have 2 pairs of congruent sides and one angle which is congruent

Paula orders a macaroni salad and coleslaw each weighing 3.75 and 2.25 pounds respectively
so, to find how many more pounds of macaroni salad than coleslaw we do,
3.75-2.25=1.50
therefore, macaroni salad has 1.50 pounds more than coleslaw.
