3. A scuba diver was exploring a reef 32.12 m below sea level. The diver ascended to the surface at a rate of 8.8 m/min. (a) Wri
Mandarinka [93]
A. T= d/r
A good way to remember this is by making a pyramid with 3 parts and putting distance at the top and rate and time in the other two parts. This way you can visibly see the equation and use it if you need to find one for rate.

B. It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something. 

C. Just plug in the numbers into the formula.
T= d/r
T= 32.12 m /<span>8.8 m/min
T= 3.65 min

If c=4h calculate C when h=7
ra1l [238]
Hey there!
In this problem, we see that c is equal to four multiplied by h.
If we plug in our value for h, we get:
c = 4(7)
Simplify right side:
c = 28
Hope this helps!

Express the polar coordinates (-1, 180) as Cartesian coordinates.
Mashcka [7]
Answer: The correct point is (1, 0)

In polar coordinates, the first number is the distance from the origin in any direction. The second number is an angle measurement that tells us the direction to go from the origin.

Therefore, we have to move -1 one unit (or backwards) from the origin. Now, all we need to know is the direction to move.

The second number is 180, so we make an angle of 180 degrees and move in that direction.

But where do we start?

We always start from the origin straight right along the x-axis. That is degrees 0. So a 180 degree angle would move us left along the x-axis. But remember, we are moving back 1 space, so we will end up at (1, 0).

Kirti has developed formulas to help her determine the size of her rectangular flower garden each spring. If she wants to plant
Ksju [112]

Answer:

A(n) = L(n) × W(n) and A(n)=0.5n^{2} +2n+2

Step-by-step explanation:

We are given that the length of the rectangular garden is L and width is W.

Also, in terms of 'n',

Length is given by, L(n) = n + 2

Width is given by, W(n) = 0.5n + 1.

Now, we know that, Area of rectangle = Length × Width.

Therefore, area of Kirti's garden is given by, A(n) = L(n) × W(n).

Thus, formula of area in terms of L(n) and W(n) is A(n) = L(n) × W(n).

Moreover, as A(n) = L(n) × W(n).

i.e. A(n) = (n+2) × (0.5n+1)

i.e. A(n)=0.5n^{2} +n+2 \times 0.5n+2

i.e. A(n)=0.5n^{2} +n+n+2

i.e. A(n)=0.5n^{2} +2n+2

Hence, the formula for area in terms of 'n' is A(n)=0.5n^{2} +2n+2.
