ian is trying to estimate the distance across the lake d. he knows the measures shown in the diagram. which estimate is closest
masya89 [10]

Answer:  The estimate is closest to the distance d is 4.2 miles


Step-by-step explanation:

In the given image, we can see that there is a right triangle, in which d is the side opposite to the right angle (largest angle in the triangle) which means its the longest side of the triangle.

[Since side opposite to the larger angle is larger]

Therefore, by Pythagoras Theorem we have

d^2=(3.6)^2+(2.2)^2\\\Rightarrow\ d^2=12.96+4.84\\\Rightarrow\ d^2=17.8\\\Rightarrow\ d=\sqrt{17.8}\\\Rightarrow\ d=4.2190\approx4.2

The estimate is closest to the distance d is 4.2 miles.

The fourth term of an=(1/2)^n is
wariber [46]

Answer:

1/16

Step-by-step explanation:

The formula for the sequence a_n=\frac{1}{2}^n is used to find the nth term of the sequence.

To find the fourth term, substitute n=4:

a_4=\left(\frac{1}{2})\right ^4,\\a_4=\frac{1^4}{2^4}=\boxed{\frac{1}{16}}

A 4500 kg vehicle and a 3700kg vehicle are both moving at a speed of 85m/s toward east.Calculate the momentum of each veheicle?
lana [24]
The momentum formula is
p = m*v

where,
p = momentum (not sure why p is chosen but many physics books tend to pick this letter)
m = mass in kilograms
v = velocity in meters per second

So let's calculate the momentum for the 4500 kg vehicle
p = m*v
p = 4500*85
p = 382500 kg m/s

And let's do the same for the 3700 kg vehicle
p = m*v
p = 3700*85
p = 314500 kg m/s
