Answer:
k = 5
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 20 when x = 4, then
20 = 4k ( divide both sides by 4 )
5 = k
4 can go into the number 50, 12 times.
To get the answer, you keep dividing by 4 until the answer is above 50.
4 times 12 is 48, so it would be able to go in 12 times. If you were to multiply higher, it would be incorrect.
Answer:
1) y = = 6.69 ft
2)x =
3)x =
4)x = 12 units
Step-by-step explanation:
The above problems can be solved by trigonometry.
1) sin(26.5) = 0.446 =
y = = 6.69 ft
2)sin(x) =
sin(x) = 0.552
x =
3) tan(x) =
x =
4) sin(45) = =
x = 12 units
