A surveyor is studying a map of the community and is using vectors to determine the distance between two schools. On the map, th

e surveyor determined that school A is at (7, 12), and school B is at (–21, –13). The scale of the map is 1 unit = 100 meters.
Which vector represents the path from school A to school B, and what is the actual distance between them?


a) components: LeftAngleBracket 28, 25 RightAngleBracket, actual distance: about 37.54 meters
b) components: LeftAngleBracket 28, 25 RightAngleBracket, actual distance: about 3,754 meters
c) components:LeftAngleBracket negative 28, negative 25 RightAngleBracket, actual distance: about 37.54 meters
d) components:LeftAngleBracket negative 28, negative 25 RightAngleBracket, actual distance: about 3,754 meters

Find the inequality represented by the graph.
Simora [160]

Answer:

y < \frac{3}{4}x

Step-by-step explanation:

Since the line is dotted and shaded down that mean the sign is <.

The slope is rise over run or 3/4.

Since the line intercepts the y-intercept at (0,0) that means that the y-int is 0

So the full equation is y < 3/4 x

1 . The lengths of the legs of a right triangle are 25 cm and 60 cm. What is the length of the hypotenuse?
Svetlanka [38]
a^{2}+ b^{2} = c^{2} that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.' 
25^{2}+ 60^{2}= x^{2}
625+3600=x^{2}
4225=x^{2}
Therefore,
\sqrt{4225}=x
65=x
The length of the hypotenuse is B.65 centimetres.

Marco is studying a type of mold that grows at a fast rate. He created the function f(x) = 345(1.30)x to model the number of mol
Ivahew [28]

1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.


Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:


345(1.30)^4 = \boxed{985.35}


Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.
