The math teacher gives each student a map of the amusement park that use a coordinate plane the meeting locates is at(0,0) on th

GrogVix [38]

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

To find:

The actual distance between first and second ride.

Solution:

Distance formula: Distance between two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using the distance formula, we get the distance between first ride and second ride in the map is

$d=\sqrt{(3-0)^2+(0-4)^2}$

$d=\sqrt{9+16}$

$d=\sqrt{25}$

$d=5$

So, the distance between first ride and second ride in the map is 5 units.

We have,

1 units = 100 ft

5 units = 500 ft

The actual distance between first and second ride is 500 ft.

Therefore, the correct option is C.

1 over the square root of 8 = 4^(m − 2)?

andrew11 [14]

Answer:

5.5

Step-by-step explanation:

$\frac{1}{ \sqrt{8} } = {4}^{(m - 2)} \\$

Squaring both sides

$\frac{1}{8} = {4}^{2(m - 2)} \\ \frac{1}{8} = {4}^{2} \times {4}^{(m - 2)} \\ \frac{1}{8 \times {4}^{2} } = {4}^{(m - 2)} \\ \frac{1}{8 \times 16} = {4}^{(m - 2)} \\ \frac{1}{128} = {4}^{(m - 2)} \\ log_{4}(128) = (m - 2) \\ \frac{7}{2} = m - 2 \\ m = \frac{11}{2} = 5.5$

Duive.

lesya692 [45]

Answer:

-27

Step-by-step explanation:

Number be x

Eight added to number: x+8

sum is doubled: 2*(x + 8)

-11 less than number: x -11

2*(x + 8) = x -11

2*x + 2*8 = x - 11

2x + 16 = x - 11

2x - x = -11 -16

x = -27
