Answer:

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-2)/(3-(-4))

m=7/(3+4)

m=7/7

m=1

Answer:

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-4, 2) and (3, 9).

Substitute:

$m=\dfrac{9-2}{3-(-4)}=\dfrac{7}{3+4}=\dfrac{7}{7}=1$

Answer:

111111 $\times$ 1111110 is the simple expression.

Step-by-step explanation:

The expression to be solved:

$\dfrac{6,666,666\times666,666 }{1+2+3+4+5+6+5+4+3+2+1} - \dfrac{777,777\times777,777}{1+2+3+4+5+6+7+6+5+4+3+2+1}$

First of all, let us solve the first term:

$\dfrac{6,666,666\times666,666 }{1+2+3+4+5+6+5+4+3+2+1}\\\Rightarrow \dfrac{6666666\times666666 }{36}\\\Rightarrow \dfrac{6666666\times666666 }{6\times 6}\\\Rightarrow 1111111\times 111111$

Now, the right term:

$\dfrac{777777\times777777}{1+2+3+4+5+6+7+6+5+4+3+2+1}\\\Rightarrow \dfrac{777777\times777777}{49}\\\Rightarrow \dfrac{777777\times777777}{7 \times 7}\\\Rightarrow 111111 \times 111111$

So, the expression to be solved becomes:

$1111111\times 111111-111111\times 111111\\\Rightarrow 111111(1111111-1)\\\Rightarrow 111111\times 1111110$

Does anyone know how to do 7a?

Calculate the circumference of the two semi circles, which equals a full circle. Then add the two sides of the track.
Circumference is pi x diameter = 3.14 x 22.8 = 71.592, so, you would need to add 71.592 + 49.2 + 49.2 = 169.992 meters, and that would be the length of one lap of the track.

Find the distance between the following points: (0,0,0) and (-2,6,3)

marusya05 [52]

9514 1404 393

Answer:

3. 7

Step-by-step explanation:

The distance formula applies in 3 dimensions as well as 2.

d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)

d = √((-2)² +6² +3²) = √(4 +36 +9) = √49

d = 7

The distance between the two points is 7 units.
