Answer:
Distance between Henry and his uncle is <u>74.25km.</u>
Step-by-step explanation:
Speed of Hawk with wind = 50+5
=55km/hr
Speed of Hawk against wind = 50-5
=45km/hr
we know that ,
Let the distance between Henry and uncle is d,
According to the question ,
d= 74.25km
Hence , the answer is 74.25km
First find slope
(8-5)/(4-0) = 3/4
Y = 3/4x + b
5 = 3/4(0) + b, b = 5
Solution: y = 3/4x + 5
Answer:
x=1 y=-5
Step-by-step explanation:
7(5x-2y=15) ---> 35x-14y=105
2(7x+7y=-28) --> + <u>14x+14y=-56</u>
49x=49 --->x=1
5(1)-2y=15 ---> 5-2y=15 ---> -2y=10 ---> y=-5
Answer:
D) The circle is centred at (-8,3) and has a diameter 20
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the circle
( x + 8)² +( y-3)² = 100
⇒ ( x + 8)² +( y-3)² = 10²
Standard form of the circle ( x-h)² +(y-k)² = r²
Centre of the circle (h , k) = (-8 , 3)
Radius of the circle r = 10
Diameter of the circle 'd' = 2r = 2(10) =20
<u><em>Final answer:-</em></u>
The circle is centred at (-8,3) and has a diameter 20
