Answer:

1.7 units

Step-by-step explanation:

Let (1.6,0.1) be (x1,y1) and (2.4,1.6) be (x2,y2)

By using distance formula,

d= sqrt (x2-x1)^2 + (y2-y1)^2

=sqrt (2.4-1.6)^2 + (1.6-0.1)^2

=sqrt (0.8)^2 + (1.5)^2

=sqrt 0.64+2.25

=sqrt 2.89

=sqrt (1.7)^2

=1.7

Therefore,the distance between them is 1.7 units

Please help! Find x if 2(x+1)=x+5
Digiron [165]

Answer:

x=3

Step-by-step explanation:

2(x+1)=x+5

Use the distributive property to multiply 2 by x+1.

2x+2=x+5

Subtract x from both sides.

2x+2−x=5

Combine 2x and −x to get x.

x+2=5

Subtract 2 from both sides.

x=5−2

Subtract 2 from 5 to get 3.

x=3

The speed of the current is 7 mph. The boat travels three times slower against the current than with the current. What is the sp
svlad2 [7]
Let
x--------> <span>the speed of the boat in mph

we know that
</span>going upstream the speed is x-7 
<span>going downstream the speed is x+7 
</span>
let the distance be d 
<span>time to go upstream = d/(x-7) </span>
<span>time to go downstream = d/(x+7)
</span>
time going upstream is 3 times going downstream 
so
<span>3d/(x+7) = d/(x-7) </span>
<span>divide by d </span>
<span>3/(x+7) = 1/(x-7) </span>
<span>3x-21 = x+7 </span>
<span>2x = 28 </span>
<span>x = 14 
</span>
the answer is
<span>the speed of the boat in still water is 14 mph</span>

The graph is falling on the left hand side and rising on the right hand side.

Since the two ends of graph are in opposite direction, the exponent of variable has to be odd. For an even exponent of leading term, the two ends are in same direction.

Since the graph is falling on left and rising on right, this indicates that the coefficient of leading term is positive.

So, the leading term must have:
1) Odd exponent
2) Positive Coefficient

Thus, option Fourth is the correct answer
