Answer:
( 8.5 , 6.5 )
Step-by-step explanation:
Midpoint formula = ( x₁ + x₂ / 2 ) , ( y₁ + y₂ / 2 )
x₁ = 4
x₂ = 13
y₁ = 10
y₂ = 3
Midpoint = ( 4 + 13 / 2 ) , ( 10 + 3 / 2 )
Midpoint = ( 17 / 2 ) , ( 13 / 2 )
Midpoint = 8.5 , 6.5
Answer:
483.87yd^2
Step-by-step explanation:
Given data
Height= 4yd
Radius= 7yd
The expression for the surface area of a cylinder is given as
Surface area= 2πr (4+ 7)
Surface area= 2*π*7 (4 + 7)
Surface area = 14π (11)
Surface area= 154*3.142
Surface area= 483.87yd^2
Hence the surface area is 483.87yd^2
4(x^2 - 1)(x - 3)(x + 3)^2 = 0
(x + 1)(x - 1)(x - 3)(x + 3) = 0
x = -1, 1, 3, -3
Cosine = adjacent/hypothenuse
Adjacent = angle between the right angle and C
Adjacent = 21
Hypothenuse = longest side
Hypothenuse = 35
Solution: 21/35
