Answer:
StartRoot 2 squared + 6 squared EndRoot
Step-by-step explanation:
we have
A(4,3) and B(-2,1)
we know that
the formula to calculate the distance between two points is equal to

substitute the given values



therefore
StartRoot 2 squared + 6 squared EndRoot
<u>Answer:</u>
The equivalent of -1/3t = 4/3 is t = -4
<u>Solution:</u>
Need to determine such value of t so that when it is multiplied by -1/3, we should get 4/3
That is we need to solve following expression for value of t.

On multiplying both the sides by 3 we get

Now multiplying both the sides by -1 we get

Let’s recheck the value of t

Hence for t = -4, expression -1/3 t is equal to 4/3.
Answer:
The answer is option 3.
Step-by-step explanation:
You have to substitute H+=2×10^(-9) into the equation of pH :
pH = -log[H+]
H+ = 2×10^(-9)
pH = -log[2×10^-9]
= 8.70 (3s.f)
Answer:
the value of X is 4dfffdrs
The proportion is 4:7 compared to the proportion ?:42. The way I prefer to do this is 7÷4=1.75. 1.75 is the difference between the smaller and larger rectangles. Then take 42÷1.75=24. The perimeter of the smaller rectangle is D. 24.
