Answer:
t =
Step-by-step explanation:
Given that t varies inversely as the square root of u then the equation relating them is
t = ← k is the constant of variation
To find k use the condition t = 3 when u = 4, thus
k = t = 3 × = 3 × 2 = 6
t = ← equation of variation
When u = 49, then
t = =
Answer:
Circumference of the smaller circle = 2.1x units
Step-by-step explanation:
Given question is incomplete; here is the complete question.
Two similar circles are shown. The circumference of the larger circle, with radius OB, is 3 times the circumference of the smaller circle, with radius OA. Radius OB measures x units. Which expression represents the circumference of the smaller circle with radius OA ?
Radius of the larger circle OB = x units
Radius of the smaller circle OA = y units
Circumference of larger circle = 2πx units
Circumference of smaller circle = 2πy units
Since circumference of larger circle is 3 times the circumference of smaller circle,
2πx = 3(2πy)
2πx = 6πy
x = 3y
y =
Therefore, circumference of the smaller circle = units
= units
= 2.094x
≈ 2.1x
Circumference of the smaller circle circle = 2.1x units
Not necessarily the case, because the function tends to infinity when sin(x) approaches 0 and it is 1 (minimum value) when sin(x) = 1. Look at the picture to know what it looks like.
Step-by-step explanation:
I hope I'm correct. I've never learnt differentiation for log and exponents before
The correct answer would be 14. When divided by 2, the answer is 7 but it is unable to be evenly divided by 6.
