Answer:

The answer to your question is $\sqrt{65}$

Step-by-step explanation:

Data

Point A = (-9, -6)

Point B = (-2, -2)

Process

To solve this problem, substitute the values in the equation.

Formula

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

- Identify the values of x1, x2, y1 and y2

x1 = -9 y1 = -6 x2 = -2 y2 = -2

-Substitution

dAB = $\sqrt{(-2 + 9)^{2}+ (-2 + 6)^{2}}$

-Simplification

dAB = $\sqrt{7^{2} + 4^{2}}$

dAB = $\sqrt{49 + 16}$

dAB = $\sqrt{65}$

lana [24]

Answer:

$Day\ 3 = 16237$

$Day\ 1 = 16390$

$Day\ 2 = 16550$

Step-by-step explanation:

Given

$Day\ 1 = 16390$

$Day\ 2 = 16550$

$Day\ 3 = 16237$

Required

Order from least to greatest

Comparing 16390, 16550 and 16237.

The order of arrangement from least to greatest is:

16327, 16390 and 16550.

So, we have:

$Day\ 3 = 16237$

$Day\ 1 = 16390$

$Day\ 2 = 16550$

Find the opposite of 1/3 and of -7/12

dimaraw [331]

Opposite number is the same number with the opposite sign:

So the opposite of $\frac{1}{3}$ is $-\frac{1}{3}$ , since the original number is positive

opposite of $- \frac{7}{12}$ is $\frac{7}{12}$ , since the original number is negative

pochemuha

Answer:

The quadratic function whose graph contains these points is $y=-x^{2}-2x-2$

Step-by-step explanation:

We know that a quadratic function is a function of the form $y=ax^{2}+bx+c$ . The first step is use the 3 points given to write 3 equations to find the values of the constants a,b, and c.
