Answer:

Step-by-step explanation:

C(3 , -2) & D (7, -8)

Distance = $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$CD = \sqrt{(7-3)^{2}+(-8-(-2))^{2}}\\\\=\sqrt{(7-3)^{2}+(-8+2)^{2}}\\\\=\sqrt{(4)^{2}+(-6)^{2}}\\\\=\sqrt{16+36}\\\\=\sqrt{52}\\\\$

A singer-songwriter wishes to compose a melody. each note in the melody must be one of the 1010 notes in her vocal range. how m

Damm [24]

I assume the question was for a sequence of 3 notes out of the possible 10. If not, use the number 1010 and 33 with the same plan.

There would be 720 different sequences.

To find the number of ways, just multiply the number of possibilities for each note.

There are 10 for the first, then 9 for the second, and finally 8.
10 x 9 x 8 = 720

While dining at yet another 5 star restaurant, which is my normal, I received the bill for $95.11 which by the way included an a

viktelen [127]

Answer:

$16.54

Step-by-step explanation:

First step we need to do is to find the bill without the 15% tips:

95.11 = 1.15x

x = $82.70 is the original bill

Now we can add the 20% tips and multiply it into the original:

82.70 x 1.2 = $99.24 is the new bill

To find out how much you tipped:

99.24 - 82.7 = $16.54 is your new tip

The graph of a linear relationship has a slope of -5 and passes through the point (2, -12). Write the equation of the line in sl

DerKrebs [107]

<h3>Answer:</h3>

y=-5x-2

<h3>Solution:</h3>

We are given the line's slope and a point that it passes through.
Using the given information, we can write the equation of the line in Point-Slope Form:
$y-y_1=m(x-x_1)$
In this formula, y₁ stands for the y-coordinate of the point, m stands for the slope of the line, and x₁ stands for the x-coordinate of the point.
In this case, y₁ is equal to -12, m is equal to -5, and x₁ is equal to 2.
Plug in the values:
y-(-12)=-5(x-2)
y+12=-5(x-2)
Now, convert into Slope-Intercept Form, y=mx+b:
y+12=-5x+10
y=-5x+10-12
y=-5x-2

Hope it helps.
