Hello the answer would be 18

Explanation:
lines KH and JK are congruent.

Line KH=c+18
Line JK=2c

2c=36 divide by 2
c=18

I don’t know how to explain it any other way.. sorry if you don’t understand but mark my answer as brainliest if it helped you out, please.

Answer:

G=(T²+N²)/4

Step-by-step explanation:

(√4G-N²)²=T²

4G-N²=T²

4G=T²+N²

G=(T²+N²)/4

Unit Test / 16 of 25

Rzqust [24]

Answer:

Step-by-step explanation:

For the minimum free throws, he must put every throw to the basket.

So, let n be the number of throws for Tuesday, in which all the throws are successful.

So, over both the days, total free throws he makes= 15+n.

Total numbers of throws that went in the basket= 6+n.

As he wants at least 80% of his balls to go in the basket.

So, 6+n is greater than or equal to 809% of 15+n, i.e

$6+n\geq \frac{80}{100}\times (15+n)$

$\Rightarrow 30+5n\geq 60+4n$

$\Rightarrow n\geq 30.$

Hence, the minimum number of free throws required on Tuesday to reach his goal is 30.

Find a formula for the general term of the sequence 5 3 , − 6 9 , 7 27 , − 8 81 , 9 243 , assuming that the pattern of the first

Mkey [24]

Answer:

The formula to the sequence

5/3, -6/9, 7/27, -8/81, 9/243, ...

(-1)^n. (4 + n). 3^(-n)

For n = 1, 2, 3, ...

Step-by-step explanation:

The sequence is

5/3, - 6/9, 7/27, - 8/81, 9/243, ...

We notice the following

- That the numbers are alternating between - and +

- That the numerator of a number is one greater than the numerator of the preceding number. The first number being 5.

- That the denominator of a number is 3 raised to the power of (2 minus the position of the number)

Using these observations, we can write a formula for the sequence.

(-1)^n for n = 1, 2, 3, ... takes care of the alternation between + and -

(4 + n) for n = 1, 2, 3, ... takes care of the numerators 5, 6, 7, 8, ...

3^(-n) for n = 1, 2, 3, ... takes care of the denominators 3, 9, 27, 81, 243, ...

Combining these, we have the formula to be

(-1)^n. (4 + n). 3^(-n)

For n = 1, 2, 3, ...
