The speed of an object in space is shown in the graph.

Mathematics
1 answer:
Virty [35]3 years ago
4 0

Step-by-step explanation:

the slope is the ratio y/x (or here distance/time) indicating how many units y changes, when x changes a certain amount of units when going from one point to another.

so, we have 2 points here

(0.2, 3)

(0.4, 6)

x (or time) changes by 0.2 units (from 0.2 to 0.4).

y (or distance) changes by 3 units (from 3 to 6).

therefore, the slope is 3/0.2 = 3/(1/5) = 3/1 / 1/5 = 3×5/1×1 = 15

that means based on the graph, that the object travels 15 miles in 1 minute.

Prove that 1/1+sinA -1/1+sinA =2tanAsinA​
enyata [817]

Step-by-step explanation:

\frac{1}{1 +  \sin( \alpha ) }  \frac{1}{1 -  \sin( \alpha ) }  \\  \frac{1 -  \sin( \alpha ) + 1 +  \sin( \alpha )  }{(1 +  \sin( \alpha ))(1 -  \sin( \alpha ))  }  \\  =  \frac{2}{1 -  {sin}^{2} \alpha }  \\  \frac{2}{ {cos}^{2} \alpha  } = 2  \:  {sec}^{2}  \alpha

8^x times 2^(4-x) = 1<br> Find x.<br> With detailed steps.
Dafna1 [17]

Answer: x= -1

Step-by-step explanation:

In mathematics when you have bases that are the same while multiplying you add the powers. In this case we do not have the same bases so we are going to make it look like 8 is 2. So we sort of simplify it. So we get 8 and put into like 2^4. We do not eliminate the power x that was already there though. So we will have 2^4x × 2^4-x. So like I said earlier we add the powers. Soo we will have

  1. 4x +4-x
  2. 4x-x=1
  3. 3x+4-4 =1-4
  4. 3x/3 = -3/3
  5. x= -1

2x + x + x + 2y × 3y × y​
Vilka [71]

Answer:

\large\boxed{4x+6y^3}

Step-by-step explanation:

2x+x+x+2y\times3y\times y\\\\=(2x+x+x)+(2y\times3y\times y)\\\\=4x+(2\times3)(y\times y\times y)\\\\=4x+6y^3

A bag contains n blue and m red marbles. You randomly pick a marble from the bag, write down its color, and then put the marble
Oksana_A [137]

Answer:

(mn+n²)/(m+n)

Step-by-step explanation:

probability of blue marble= n/(n+m)

probability of red marble= m/(n+m)

probability that process stops = Probability of both blue + probability of both red=  n/(n+m) × n/(n+m) + m/(n+m)×m/(n+m)

                        = (n²+m²)/(n+m)²

P(1st marbel is blue)= P(blue and red) + P(blue and blue)

                                  = mn/(n+m) + n²/(n+m)

                                   = (mn+n²)/(m+n)

P(1st marble is blue | process stops)= ( (mn+n²)/(m+n)× (n²+m²)/(n+m)²)/ ((n²+m²)/(n+m)²)

= (mn+n²)/(m+n)
