Here we have to find the length of arc AB.

Length of an arc = ( central angle/360)×2 πr

= ( 64.6 / 360 ) × 2 × 5 miles × 22 / 7

= 0.179 × 220 miles / 7

= 39.38 miles / 7

= 5.625 miles.

The required answer is 5.625 miles.

Remark
The circumference of a complete circle = 2*pi*r
A part of the circumference = k * 2* pi * r / 360 where k is the measure of any central angle.

Givens
k = 64.6 degrees
r = 5 miles

Formula
Walking distance = k/360 * 2 * pi * r

Sub and Solve
Walking Distance = (64.6/360) * 2 * 3.14 * 5
Walking distance = 5.6346 miles

Position vectors m and n have terminal points of (2, ) and (1, y), respectively.
OLEGan [10]
This problem involves the dot product.

You must provide all info for position vector m.  Your (2,) is inadequate.

Supposing that the terminal point of vector m were (2,3), then

m dot n would equal 8, or 8 = 2*2+3*y.  Then 8 = 4 + 3y, and 4 = 3y, and y =3/4.

Please type in the terminal point of vector m and then answer this question following the above example.

Factor completely 4x2 16x. 4x(x 4) x(4x 4) 4(x2 4x) Prime.
vladimir2022 [97]

Answer:

4x(x+4)

Step-by-step explanation:

With the expression 4x^{2} +16x, start by looking to see if you can take out any x-values. As you can see, both 4x^{2} and 16x have an x to the first power. You can factor that out, leaving you with the expression x(4x+16). Now you look for the largest numerical value that you can take out. Both 4 and 16 are divisible by 4, so you can factor out the number 4, leaving you with the expression 4x(x+4).

A passenger traub keaves a depot 1.5 hours after a freight train leaves the same depot. The passenger train is travleing 18 mph
skelet666 [1.2K]

Answer:

Speed of passenger train=18+30=48 mph

Speed of freight train=30 mph

Step-by-step explanation:

Let x be the speed of freight train.

Speed of passenger train=x+18 mph

Time taken by freight train=1.5+2.5=4 hrs

Time taken by passenger train to overtake the freight train=2.5 hrs

Distance=Speed\times time

By using this formula

Distance traveled by passenger train=2.5(x+18)  miles

Distance traveled freight train=4x

According to question

2.5(x+18)=4x

2.5 x+45=4x

45=4x-2.5 x

45=1.5 x

x=\frac{45}{1.5}=30

Speed of freight train=30 mph

Speed of passenger train=18+30=48 mph
