For the plane curve defined by x = 7 cos t, y = 5 cos t, for t in [0, 2π] the ordered pair that corresponds to t = π/6 is ___

Allushta [10]

Answer:

The ordered pair is: $(\frac{7\sqrt{3}}{2},\frac{5\sqrt{3}}{2})$

Step-by-step explanation:

We are given the following plane curve:

$x = 7 \cos{t}$

$y = 5 \cos{t}$

Ordered pair for a value of t:

We find (x,y) for these values of t. So, when $t = \frac{\pi}{6}$

$x = 7 \cos{\frac{\pi}{6}} = 7\frac{\sqrt{3}}{2} = \frac{7\sqrt{3}}{2}$

$y = 5 \cos{\frac{\pi}{6}} = 5\frac{\sqrt{3}}{2} = \frac{5\sqrt{3}}{2}$

The ordered pair is: $(\frac{7\sqrt{3}}{2},\frac{5\sqrt{3}}{2})$

The radius of a cylinder is 3x – 2 cm. The height of the cylinder is x +3 cm. What is the

VashaNatasha [74]

Surface Area of the cylinder is 6x² + 83x - 58 cm²

Step-by-step explanation:

Step 1: Given surface area of the cylinder, A = 23r + 2rh. Here, r = (3x - 2) and h = (x + 3)

⇒ A = 23(3x - 2) + 2(3x - 2)(x + 3)

⇒ A = 69x - 46 + (6x² + 18x - 4x - 12)

⇒ A = 6x² + 83x - 58 cm²

Consider the following formula used to estimate the height, h, of a seeding after w weeks since planting h=(1/5)w + (8/5)which o

Bogdan [553]

Answer:

w=5h-8

Step-by-step explanation:

Take the original formula h=(1/5)w+(8/5)

Subtract -8/5 on both sides to isolate the w, so h-8/5=(1/5)w

Now you have to get rid of the 1/5, so multiply 5(h-8/5), the 5 in the 8/5 cross each other out. You are left with 5h-8
