Find an equation of the circle that has center (-1, 3) and passes through (1. 1)

pshichka [43]

Answer:

(x + 1)² + (y - 3)² = 8

Step-by-step explanation:

radius (r): √(1 - (-1))² + (1 - 3)² = √8 = 2√2

Formula for circle with center (h,k): (x – h)² + (y – k)² = r²

(x + 1)² + (y - 3)² = 8

In a study investigating a link between walking and improved health, researchers reported that adults walked an average of 873

Rainbow [258]

Answer:

$H_0:\mu =873\\\\H_a: \mu$

Step-by-step explanation:

Given : In a study investigating a link between walking and improved health, researchers reported that adults walked an average of 873 minutes in the past month for the purpose of health or recreation.

Claim : The true average number of minutes in the past month that adults walked for the purpose of health or recreation is lower than 873 minutes.

i.e. $\mu$

We know that the null hypothesis contains equal sign , then the set of hypothesis for the given situation will be :-

$H_0:\mu =873\\\\H_a: \mu$

Which equation represents the line that is perpendicular yo y=3/2x+1 and passes through (-12,6)

klemol [59]

Answer:

y = -2/3x - 2

Step-by-step explanation:

Step 1: Find slope m of perpendicular line

Simply take the negative reciprocal of the given line

m = -2/3

y = -2/3x + b

Step 2: Find b

6 = -2/3(-12) + b

6 = 8 + b

b = -2

Step 3: Rewrite perpendicular equation

y = -2/3x - 2
