Standard form of a circle" (x-h)²+(y-k)²=r², (h,k) being the center, r being the radius.
in this case, h=-2, k=6, (x+2)²+(y-6)²=r²
use the point (-2,10) to find r: (-2+2)²+(10-6)²=r², r=4
so the equation of the circle is: (x+2)²+(y-6)²=4²

Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. {5,5/3,5/9,5
Tanya [424]

The formula for the general term of the given sequence 5, 5/3, 5/9, 5/27 is  a_{n} = \frac{5}{3^{n} }.

According to the given question.

We have a sequence  5, 5/3, 5/9, 5/27.

As, we know that "a sequence is an arrangement of any objects or a set of numbers in a particular order followed by some rule"

If we see the given sequence 5, 5/3, 5/9, 5/27 it is following a pattern in which the nummerator of all the terms are same but the denominator is increasing by by power to 3 like 3^0 = 1, 3^1 = 3, 3^2 = 9 and so on.

Thereofre, the genereal term  a_{n}, of the given sequence is given by

a_{n} = \frac{5}{x^{n} } , where n belong to whole numbers.

Hence, the formula for the general term of the given sequence 5, 5/3, 5/9, 5/27 is  a_{n} = \frac{5}{3^{n} }.

1)1.10w+2.35(172-s)=294.20
When you solve
1.10x+2.35(172-x)=294.20 solve for x
X water=88
S=172-88=84
2)2t+4(40-f)=100
When you solve
2x+4(40-x)=100 solve for x
X=30 for t
40-30=10 for f
Hope it helps

Tony owns a car lot. He orders cars and motorcycles at a ratio 5:2. Find an equivalent ratio if Tony ordered 25 cars. Then find
Romashka-Z-Leto [24]

Answer:

10 motorcycles and 30 cars

Step-by-step explanation:

If there are 25 cars and a 5:2 ratio, then 25/5=5, and 5x2=10, then there will be 10 motorcycles.

                   5:2

   Divide by 5 | Multiply by 2

If there are 12 motorcycles, then 12/2=6 and 6x5=30. The ratio is reversed because the translation required is reversed.

                     2:5

   Divide by 2 | Multiply by 5

Question 2 (1 point)<br>What is the range of the data below?<br>42?<br>28?<br>41?<br>22?​
maxonik [38]

Answer:

the range is 20

Step-by-step explanation:

so here is how you find the range here is an example

the range data is 42 , 28 , 41, and 22

you first order  the range data from least to greatest which is 22 , 28 , 41 , 42

after you order the numbers you want to get the largest number from the data and subtract it from the smallest number in the data which is 42 - 22 = 20

20 is the range

i hope this helps. i had this question on my test today and got a 100%
