Which expression can be used to determine the length of segment AB? On a coordinate plane, triangle A B C has points (4, 3), (ne

JulijaS [17]

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

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the given values

$AB=\sqrt{(1-3)^{2}+(-2-4)^{2}}$

$AB=\sqrt{(-2)^{2}+(-6)^{2}}$

$AB=\sqrt{40}\ units$

therefore

StartRoot 2 squared + 6 squared EndRoot

What is equivalent to -1/3t=4/3

stepan [7]

<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.

$-\frac{1}{3} t=\frac{4}{3}$

On multiplying both the sides by 3 we get

$\begin{array}{l}{-\frac{1}{3} t \times 3=\frac{4}{3} \times 3} \\\\ {=>-t=4}\end{array}$

Now multiplying both the sides by -1 we get

$\begin{array}{l}{-t \times-1=4 \times-1} \\ {=>t=-4}\end{array}$

Let’s recheck the value of t

$-\frac{1}{3} t=-\frac{1}{3} \times-4=\frac{4}{3}$

Hence for t = -4, expression -1/3 t is equal to 4/3.

Anyone I’m really lost

Savatey [412]

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)

The ratio of the perimeters of two rectangles is 4 to 7. The perimeter of the larger rectangle is 42 inches.

adelina 88 [10]

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.
