I NEED HELP PLS!!!!

hram777 [196]

Answer:

15

Step-by-step explanation:

For these kind of problems, its best to use a Venn Diagram.

Lets break down the information:

<em>There are 50 students total.</em>

<em>25 take Math competiton classes.</em>

<em>29 take Geometry</em>

<em>12 take history and </em><em><u>no math classes</u></em>

<em>19 take </em><em><u>both math classes</u></em>

Now, make a Venn Diagram.

[Look at the photo attached. Also, the blank spaces in the Venn Diagram are ones that no student takes.]

The 12 taking history and no math classes and 3 kids not taking any of those classes look like they're the only ones not taking either math class.

12 + 3 = 15.

So the answer is 15.

[I'm not sure if this is correct or if I made a mistake so please let me know! Thank you! I hope this helps!]

A sequence starts from -2. The term to term rule is 'square and subtract 3' find the first six numbers of the sequence

alexandr1967 [171]

Answer:

The first six numbers are $-2,1,-2,1,-2,1$

Step-by-step explanation:

First term is $-2$

The term to term rule is 'square and subtract $3$ '

Second term $=(-2)^{2} -3=1$

Third term $=(1)^{2} -3=-2$

Fourth term $=(-2)^{2} -3=1$

Fifth term $=(1)^{2} -3=-2$

Sixth term $=(-2)^{2} -3=1$

The first six numbers are $-2,1,-2,1,-2,1$

Problem: A piece of farmland is a watering plot of land in a circular pattern. A sewer line needs to be installed from a new hou

Musya8 [376]

The entry and exit points of (2, 3), and (12, 6), and 200 ft. extension of the sprinkler system gives;

(1) The sewer line crosses the farmland at (6.53, 4.36), and (8.48, 4.9)

(2) The longest installable sprinkler system is approximately 172.4 feet

<h3>How can the points where the line crosses the farmland be found?</h3>

1. The slope of the sewer line is found as follows;

m = (6 - 3)/(12 - 2) = 3/10 = 0.3

The equation of the sewer line can be expressed in point and slope form as follows;

(y - 3) = 0.3×(x - 2)

y = 0.3•x - 0.6 + 3

y = 0.3•x + 2.4

The equation of the circumference of the sprinkler can be expressed as follows;

(x - 8)² + (y - 3)² = 2²

Therefore;

(x - 8)² + (0.3•x + 2.4 - 3)² = 2²

Solving gives;

x= 6.53, or x = 8.48

y = 0.3×6.53 + 2.4 = 4.36

y = 0.3×8.48 + 2.4 = 4.9

Therefore;

The sewer line crosses the farmland at (6.53, 4.36), and (8.48, 4.9)

2. When the farmland does not cross the sewer line, we have;

sewer line is tangent to circumference of farmland

Slope of radial line from center of the land is therefore;

m1 = -1/0.3

Equation of the radial line to the point the sewer line is tangent to the circumference is therefore;

y - 3 = (-1/0.3)×(x - 8)

Which gives;

y = (-1/0.3)×(x - 8) + 3

The x-coordinate is therefore;

0.3•x + 2.4 = (-1/0.3)×(x - 8) + 3

x ≈ 7.5

y = 0.3 × 7.5 + 2.4 ≈ 4.65

The longest sprinkler system is therefore;

d = √((7.5 - 8)² + (4.65 - 3)²) ≈ 1.724

Which gives;

The longest sprinkler system is 1.724 × 100 ft. ≈ 172.4 ft.
