The distance between R and S on the coordinate grid is ___ units. (Input whole numbers only.)
Anna35 [415]

Answer:

35

Step-by-step explanation:

coordinate of point S(20,5) and R(-15,5)

Distance between S and R is given by,

\sqrt{ {(x2 - x1)}^{2}  +  {(y 2 - y1)}^{2} } \\   \sqrt{ {(20 - ( - 15))}^{2} +  {(5 - 5)}^{2}  }  \\  \sqrt{ {(20 + 15)}^{2}  + 0}  \\  \sqrt{ {(35)}^{2} }  = 35units

the first term of an arithmetic sequence is equal to 200 and the common differencence is equal to -10. find the value of the 20t
olga_2 [115]

Answer:

The value for 20th term is 10.

Step-by-step explanation:

First, you have to find the formula for the sequence.

an = a + d(n - 1)

let \: a = 200,d =  - 10

an = 200 - 10(n - 1)

an = 200 - 10n + 10

an =  - 10n + 210

Given that the formula of this sequence is an = -10n + 210. Next, you have to find 20th term :

let \:n = 20

20th \: term =  - 10(20) + 210

20th \: term =  - 200 + 210

20th \: term = 10

(Correct me if I am wrong)

Which quadratic equation has roots - 2 and 1/5 :
Sladkaya [172]

Answer:

5 {x}^{2}  \:  +  \: 8x \:  - 2 \:  =  \: 0

Step-by-step explanation:

sum \: of roots =  - 2 +  \frac{1}{5}  = - \frac{8}{5}  \\ product \: of \: roots =  - 2 \times  \frac{1}{5}  =  -  \frac{2}{5}  \\ from \: general \: equation \\ a {x}^{2}  + bx + c = 0 \\  {x}^{2}  +  \frac{8}{5} x  \: -   \frac{2}{5}  = 0 \\ 5 {x}^{2}   \:  +  \: 8x \:  - 2 \:  =  \: 0
