Mathematics
1 answer:
Tamiku [17]4 years ago
3 0

Answer:

Step-by-step explanation:

d^2 = (x2 - x1)^2 + (y2 - y1)^2

x1 = 9

x2 = -1

y1 = -3

y2 = 8

d^2 = (-1 -9)^2 + (8 - - 3)^2

d^2 = (-10)^2 + 11^2

d^2 = 100 + 121^2

d^2 = 221

221 is not prime, it is 13 * 17 which doesn't factor down any further.

So

d = sqrt(221)

Using the pythagorean theorem, calculate the length of the missing sides (c1, c2, c3)​
katrin [286]

Answer:

the Pythagorean theorem states:  a^2 + b^2 = c^2  

1) in this case a=18 and b1=25

18^2 + 25^2 = c1^2  

324 + 625 = c1^2

949 = c1^2

√949 = c1

cca. 30.8 = c1

2) in this case a=18 and b' = b2 - b1 = 40 - 25 = 15

in the picture im attaching i highlighted the triangles we are working with, and there you can clearly see that b' (the horizontal line at the bottom of the red tr.) is the difference between the lines b2 and b1

now you can use the same technique as in the first case, and the final answer will be cca. 23.4 = c2

3) in this case a=18 and b'' = b4 - b3 = 75 - 55 = 20

same thing as number 2, final answer cca. 26.9 = c3

How do I solve these equations?
zimovet [89]
Can you use a calculator? If yes, then isolate 7) cot 8) tan 2 theta, etc. Then, input the inverse of that trig into the calculator. 

Ex. #7 cot theta= -6/5
Then, input arccot (-6/5) (aka inverse cot (-6/5)) into your calculator.

There are 18 pieces of chalk. The ratio of chalk that is yellow to chalk that is not yellow is 1:2. How many pieces of chalk are
vovangra [49]

Number of pieces of chalk that are yellow is 6

<h3><u>Solution:</u></h3>

Given that there are 18 pieces of chalk

To find: number of pieces of chalk that are yellow

Given that,  ratio of chalk that is yellow to chalk that is not yellow is 1 : 2

Therefore,

chalk that is yellow : chalk that is not yellow = 1 : 2

Let the chalk that is yellow be 1x

Let the chalk that is not yellow be 2x

Also, total pieces of chalk = 18

That is,

chalk that is yellow + chalk that is not yellow = 18

1x + 2x = 18

3x = 18

x = 6

number of pieces of chalk that are yellow = 1x = 1(6) = 6

Thus 6 chalk pieces are yellow
