Best explained/correct answer gets brainliest.
Nuetrik [128]
3, 15, 75, 375, and here's why:
Basically, it's asking you to take 3, and multiply it by five each time to get a pattern.

1: 3
2: 
3*5 = 15
3: 
15*5 = 75
4: 
75*5 = 375

Add these together: 
3 + 15 + 75 + 375 = 468

Your answer is "A)", 468.

Find an equation of the line perpendicular to the graph of 14x-7y=8 that passing through the point at (-2,5).
MAXImum [283]

Answer:

2x + 4y = 16.

Step-by-step explanation:

14x - 7y = 8

Convert to slope-intercept form:

-7y = -14x + 8

y = 2x - 8/7

The slope is 2 so the line perpendicular to it has a slope of -1/2, so we have:

y = 1/2x + c

This line passes through the point (-2, 5) so:

5 = -1/2* (-2) + c

5 = 1 + c

c = 5 - 1 = 4

So our equation is y = -1/2x + 4.

Convert to standard from

4y = -2x + 16

2x + 4y = 16.

Helpppp plzzz The frequency histogram shows the lengths of trails in a large park.
Rus_ich [418]

Answer:

13 trails

Step-by-step explanation:

The histogram shows following numbers of trails:

  • <u>0 - 6 km long</u> - 5 trails;
  • 6 - 12 km long - 9 trails;
  • 12 - 18 km long - 7 trails;
  • 18 - 24 km long - 3 trails;
  • <u>24 - 30 km long</u> - 4 trails;
  • <u>30 - 36 km long</u> - 1 trail;
  • <u>36 - 42 km long</u> - 3 trails.

So, there are 5 trails with length less than 6 km and 4 + 1 + 3 = 8 trails that are at least 24 km long.

In total, 5 + 8 = 13 trails
