Answer:
B = (-7,10)
Step-by-step explanation:
Given that , a line AB has midpoint (-2,4) and the coordinates of A is ( 3 , -2). We need to find out the coordinates of B .
- Let coordinate of B be ( p,q ). We can use midpoint formula , as ,
=> Midpoint = ( x₁ + x₂ / 2 , y₁ + y₂/2 )
=> ( -2,4 ) = ( p + 3)/2 , ( q -2 )/2
=> -2 = p + 3/2
=> p + 3 = -4
=> p = -3 - 4
=> p = (-7)
<u>Also </u><u>:</u><u>-</u><u> </u>
=> q - 2/2 = 4
=> q -2 = 8
=> q = 8 + 2
=> q = 10
<h3>
<u>Hence</u><u> the</u><u> </u><u>coordinates</u><u> </u><u>of </u><u>B </u><u>is</u><u> </u><u>(</u><u> </u><u>-</u><u>7</u><u>,</u><u>1</u><u>0</u><u> </u><u>)</u><u> </u><u>.</u></h3>
0.125 the first one, even though im not sure.
First, find the amount of time is taken to travel 1 mile :
time taken to travel 1 mile = 20/6 = 3 ⅓ mins
hence, time taken to travel 9 miles = 3 ⅓ x 9 = 30 mins
time taken to travel 10 miles = 3 ⅓ x 10 = 33 ⅓ mins
Answer:
H >= 6.25
6.5 hours per week
Step-by-step explanation:
75-50=25
JT must complete 25 more hours of exercise in 4 weeks. 25/4=6.25. So JT has to exercise 6.5 hours each week.
>= (means greater than or equal to)
