Suppose a spherical balloon grows in such a way that after t seconds, its volume is V = 4 sqrt(t) cm3.

1 answer:

3 0

The volume at time t = 25 seconds
since V = 4 sqrt(t) cm3,
V(5)= 4*sqrt(25)cm^3=4*5=20cm^3

Answer: Slope: -1/2

Step-by-step explanation: To find slope take 2 points that lie on the line and use this formula to solve: I will use (0, -2) and (2, -3) to solve

↑ ↑ ↑ ↑

y2 - y1 x1 y1 x2 y2

-----------

x2 - x1

So, for this question, substitute the x and y values from the points above to solve.

-3 - (-2)

----------- = - 1/2

2 - 0

Hope this helped. :)

xand y are light house. y being 20km due east of x and from a ship due south of x the bearing of y was 055°. what is the distanc

leonid [27]

Answer:

I) |xz| ≈ 28.6 km

II) |yz| ≈ 34.8 km

Step-by-step explanation:

Let's assume that the position of ship due south of x is z (aà pictor representation of the question is attached)

|xy| = 20 km, |xz| = ?, |yz| = ?, θ(y) = 55°

Using Trigonometric ratio - SOHCAHTOA

I) Tan θ = |xz| ÷ |xy| ⇒ Tan 55° = |xz| ÷ 20

|xz| = 20 * Tan 55 = 20 * 1.428

|xz| = 28.56 km

|xz| ≈ 28.6 km

II) Cos θ = |xy| ÷ |yz| ⇒ Cos 55° = 20 ÷ |yz|

|yz| * Cos 55° = 20 ⇒ |yz| = 20 ÷ Cos 55°

|yz| = 20 ÷ 0.574 = 34.84 km

|yz| ≈ 34.8 km
