Two trains are traveling at constant speeds on different tracks.

Two Trains Are Traveling At Constant Speeds On Different Tracks.

Answers

Answer 1

Answer:

Train B is traveling faster

Step-by-step explanation:

From the picture, we want to know which train is traveling faster

We can know this by knowing the speed of the trains

Mathematically;

speed = distance/time

Train A

12.5 m in 1 second

speed = 12.5/1 = 12.5 m/s

Train B

100 m in 4 seconds

speed = 100/4 = 25 m/s

So train B is traveling faster

This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m

in 1 second

[tex]x = 110 \\ (exterio \: angles \: of \: a \: traingle \: sum \: up \: to \: 360)[/tex]

Answer:

x = 110

Step-by-step explanation:

Assuming you require the value of x

The sum of the external angles of a triangle = 360°

The 3 angles shown are external angles.

Subtract the sum of the 2 given angles from 360 for x

x = 360 - (140 + 110) = 360 - 250 = 110

Using the variables it gives us it is B=150m

Step-by-step explanation:

1.) $1800-$1350=$450

$1350 is the total balance after 3 months and $450 is the amount he has payed in those 3 months

2.) 450/3=150

You do 450/3 to find how much he is paying per month. If you want to check your work do 1800-1050=750 then do 750/5=150

So you put the numbers in B = Zachary's balance after m months and you get B=150m

the initial fee for the installation, $35
the initial fee for the installation, $100
the cost per hour of installation work, $35
the number of hours to complete the installation, x

Answers

Answer:

the cost per hour of installation work, $35

Step-by-step explanation:

y = 35x + 100

the slope of a function is the coefficient of x, therefore, it is 35. $100 is the initial fee, since it ia the y intercept, and $35 is the cost per hour. y is the total amount, and x is the number of hours. Therefore, the only possible answer is the third choice,

Find the zeros of the function algebraically.
f(x) = 16x4 − 49x2

Answers

Answer: Plz mark me brainlest

Step-by-step explanation:

Just Simply Use Identity:

 

  a^2 - b^2 = ( a+b) ( a-b)

   Then:

     ( 49X^4 - 36 X^2) = 0

       (7 X^2 + 6 X) ( 7X^2 - 6X) =0

       7X^2 + 6X = 0, then           X( 7X +6) =0    X=0,  7x +6 =0   X = -6/7

           7X^2 -6x =0                   X( 7x - 6) =0   X =0   7x -6 =0    X =6/7

Pull out a factor of x² from f(x) :

16x⁴ - 49x² = x² (16x² - 49)

Now write it as a difference of squares, then factorize:

16x⁴ - 49x² = x² ((4x)² - 7²)

16x⁴ - 49x² = x² (4x - 7) (4x + 7)

Set this equal to 0 and solve for x :

x² (4x - 7) (4x + 7) = 0

x² = 0   or   4x - 7 = 0   or   4x + 7 = 0

x = 0   or   x = 7/4   or   x = -7/4

sin^2x + sin^2x + cos²x

Answers

Answer:

Answer:

A. 2 sinx cosx - 1 + 2 sin^2 x.

Step-by-step explanation:

sin2x = 2 sinx cosx

cos2x = cos^2x - sin^2x

So sin2x - cos2x =  2 sinx cosx - ( cos^2x - sin^2x)

But cos^2 x = 1 - sin^2 x, so we have:

2 sinx cosx - (1 - sin^2 x - sin^2x)

= 2 sinx cosx - 1 + 2 sin^2 x.
