Malcom coasted 32 miles from moon ridge to me tone and then pedaled back hard. If the round trip took 4 hours, what was malcoms
AURORKA [14]

Answer:

Malcom's average speed was 16 miles/hour.

Step-by-step explanation:

Given:

Distance from moon ridge to me tone = 32 miles.

Now including returned back journey.

So we can say that.

Total distance traveled = 32+32 =64\ miles

Also Given:

Time taken to travel total distance = 4 hours.

We need to find the average speed in miles per hour.

Solution:

Now we know that;

average speed is equal to Total distance traveled divided by Total time taken to travel the total distance.

framing in equation form we get;

average speed = \frac{64}{4}=16 \ mi/hr

Hence Malcom's average speed was 16 miles/hour.

3e-4=6e(45+2e) what's e
Lyrx [107]

Answer:

​  Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*e-4-(6*e*(45+2*e))=0  

Step by step solution :

Pulling out like terms

3.1     Pull out like factors :

  -12e2 - 267e - 4  =   -1 • (12e2 + 267e + 4)  

Trying to factor by splitting the middle term

3.2     Factoring  12e2 + 267e + 4  

The first term is,  12e2  its coefficient is  12 .

The middle term is,  +267e  its coefficient is  267 .

The last term, "the constant", is  +4  

Step-1 : Multiply the coefficient of the first term by the constant   12 • 4 = 48  

Step-2 : Find two factors of  48  whose sum equals the coefficient of the middle term, which is   267 .

Find the initial point P of a vector u with terminal point Q(2,0,2), such that:9Fdhe iiial point P of a vector iu with terminal
denpristay [2]

Answer:

  a)  P = (-3, 4, 3)

  b)  P = (7, 4, 1)

Step-by-step explanation:

a) You want Q-P = (5, 4, -1) where Q = (2, 0, 2). Solving for P, we get ...

  P = Q - (5, 4, -1) = (2-5, 4-0, 2-(-1))

  P = (-3, 4, 3)

__

b) The vector in the opposite direction of the one given is the given one multiplied by -1.

  P = Q - (-1)(5, 4, -1) = (2+5, 0+4, 2-1)

  P = (7, 4, 1)
