SCUBA diving set

Mathematics
1 answer:
lys-0071 [83]3 years ago
4 0

Answer:

Step-by-step explanation:

Snorkel, mask, and flippers Slope: 2 (so in the equation, it would look like 2x).

Snorkel, mask, and flippers Y-intercept: 10 (12 - 2 = 10, which is 0 hours, possibly the initial amount)

Snorkel, mask, and flippers Slope intercept form: y = 2x + 10

The hull speed of a boat in knots per hour is determined by the length of the waterline. The waterline is the length of the boat
777dan777 [17]

Answer:

The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.

Step-by-step explanation:

Let the function h = 1.34\cdot l, where l is the length of the waterline, measured in feet and h is the hull speed of the boat, measured in knots per hour. If we know that h = 4\,\frac{kt}{h}, then the length of the waterline is:

l = \frac{h}{1.34}

l = \frac{4}{1.34}

l = 2.985\, ft

The length of the waterline when hull speed is 4 knots per hour in feet is 2.985 feet.

if kevin took 1/10 of an hour to use 1/2 of package of napkins. how many hours would it take to use 2 packages?
sladkih [1.3K]

Answer:

2/5 hours

Step-by-step explanation:

We can write a proportion to solve

1/10 hour          x hours

----------------   = -------------------

1/2 package        2 packages

Using cross products

1/10 * 2 = 1/2 x

1/5 = 1/2x

Multiply each side by 2

1/5 * 2 = 1/2x *2

2/5  =x

2/5 hours

Suppose you begin a job with an annual salary of $32,900. Each year you are assured of a 5.5% raise. What its the total amount t
olga2289 [7]

Answer: the total amount that you can earn in 15 years is $737245. Option C

Step-by-step explanation:

You receive an annual salary of $32,900 and each year, you are assured of a 5.5% raise. Assuming there was no raise, you get 100% of your previous salary each year. With a raise of 5.5%, you will get 100 + 5.5 = 105.5% of your previous salary for each year. This is a geometric progression and we want to determine the sum of 15 terms(15 years).

The formula for the sum of terms in a geometric progression is

Sn = [a(r^n - 1)]/ r - 1

Sn = sum of n terms

a = the first term

n = number of terms

r = common ratio

From the information given,

a = 32900

n = 15

r = 105.5/100 = 1.055

S15 = [32900(1.055^15 - 1)] / 1.055 - 1

S15 = [32900(2.23247649 - 1)] / 0.055

S15 = 32900 × 1.23247649) / 0.055

S15 = 737245.0277

S15 = $737245

PLEASE HELP! NEED TO SUBMIT ASAP!!!!!!!! PLEASE, THANK YOU IN ADVANCE!!!!! 11PTS

This is a table with 6 lines.
In each line, the number in the first column is the 'x' value.

All you have to do on each line is ...

--- substitute the 'x' value in (100 + 23x), simplify it,
and write the result in the middle column

then

--- substitute the 'x' number in  90(1.2ˣ) , simplify it,
and write the result in the last column.

On the first line, x=0.

100 + 23x  =  100 + 0 = 100.  Write 100 in the middle column.

90(1.2ˣ) = 90(1) = 90.  Write 90 in the last column.

Then go on to the second line, where x=1.

You'll make it.

What is the equation of the line that passes through the point (-5,-2) and has a slope of -6/5
tatyana61 [14]

Answer:

The answer is

<h2>y =  -  \frac{6}{5} x - 8  \\</h2>

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1) \\

where

m is the slope

( x1 , y1) is the point

From the question the point is (-5,-2) and the slope is - 6/5

The equation of the line is

y + 2 =  -  \frac{6}{5} (x + 5) \\ y + 2  =  -  \frac{6}{5} x - 6 \\ y =  -  \frac{6}{5} x - 6 - 2

We have the final answer as

y =  -  \frac{6}{5} x - 8  \\

Hope this helps you
