A submarine submerged at a depth of -35.25 meters dives an additional 8.5 meters.What is the new depth of the submarine

1 answer:

3 0

A submarine is now at a depth of -35,25 meters. If it dives 8,5 more, we need to subtract that from the current depth, like so:

-35,25 - 8,5 = -43,75 meters

Answer:

Step-by-step explanation:

We would apply the formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the population after t years.

t represents the number of years.

P represents the initial population.

r represents rate of growth.

From the information given,

P = 5655

r = 1.4% = 1.4/100 = 0.14,

a) Therefore, the equation that estimates the population t years after 2010 is

A = 5655(1 + 0.14)^t

A = 5655(1.14)^t

b) in 2022, the number of years t = 2022 - 2010 = 12

Therefore,

A = 5655(1.14)^12

A = 27245

Use matrix inversion to solve the collection of systems of linear equations. HINT [See Example 4.] (a) −x − 4y + 2z = −10 x + 2y

omeli [17]

Answer:

Step-by-step explanation:

given is a system of linear equations in 3 variables as

$-x - 4y + 2z = −10\\ x + 2y - z = 11 \\x + y - z = 14$

This can be represented in matrix form as

AX=B Or

$\left[\begin{array}{ccc}-1&-4&2\\1&2&-1\\1&1&-1\end{array}\right] *\left[\begin{array}{ccc}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}-10\\11\\14\end{array}\right]$

So solution set

X would be $A^{-1} B$

|A|=-1(-1)+4(0)+2(-1)=--1

Cofactors of A are

-1 0 -1

-2 -1 -3

0 1 2

So inverse of A is

1 2 0

0 1 -1

1 3 -2

Solution set would be

x=12

y=-3

z=-5

Barb is making a bead necklace. She strings 1 white bead,then 3 blue beads,then 1 white bead,and so on. Write the numbers for th

nataly862011 [7]

The numbers for the first eight beads that are white are; 1, 5, 9, 13, 17, 21, 25, 29

<h3>Arithmetic Sequence</h3>

We are told that she strings in this order;

1 white
3 blue
1 white bead

Now, after the first white bead, the next white bead is the 5th bead in total.

This means the difference in interval between white beads is; 5 - 1 = 4 beads

Thus, the numbers for the first eight beads that are white are;

1, (1 + 4), (1 + 4 + 4), (1 + 4 + 4 + 4).....

Thus, we have;

1, 5, 9, 13, 17, 21, 25, 29
